You're welcome


Sand of time team : Antoher fantastic guide is by a user of our very own Sands of Time mod!  His in depth guide will most definitly get you pointed in the right direction.  In fact, our very own optimization guide intitially helped him out with modding his own game.  After reading through his excellent guide, we were gratefule to be an influence / aid to / for him. We suggest you check it out!
ff7legend : Your guide has helped me stabilize my game big time. Especially the bit regarding the making of a Merged Patch in TES5Edit [...]Just handed you a kudos Sthaagg for providing such a helpful guide & the quick updates to your guide.
Shagreth : You f***ing rock, thank you for writing all this down for us. This has to be the best performance guide out there at the moment, sure, there are other great ones -- but none have kept up with the times.
RageSpike : Thanks so much for this guide and your advise, I haven't crashed a single time yet and I play with a lot more mods and 2k textures.
Looks like the last thing that needed fixing was my OS after the guide settings.

I just can't believe how well it runs, I've gotten used to the crashes, if I don't crash in 1 hours I called that good, now it just never happens!
BlueGunk : You have some excellent advice here. Thanks and well done - a help for a lot of people. I got to a lot of this through trial and error, and learning. I wish I could have had your page here in earlier times!
MrFlame : Your guide is a must for every ENB user, it's incredible, my FPS is now almost 56-58 EVERYWHERE, i mean EVERYWHERE, even with that killer SFO 2.0+ mod installed ! Thank you so much :) !
I've been struggling with performance and stuttering ussues for more than 800+ hours of Skyrim and now it's just whao
Baloo42 : This guide is so good, it should be deemed illegal, and considered as Skyrim porn, more illegal than 7B-Bombshell. The Skyrim Holy Grail! - Keep spreading the good word


This guide is designed as a comprehensive tutorial for optimizing your PC, adjusting configuration settings, and maximizing performance of your Skyrim game play. It starts with preparing your PC, with recommendations for INI files, dealing with mod conflicts, setting up Crash Fixes, installing and configuring ENBoost or ENB presets, and other tweaks and fixes. I hope you find this guide beneficial.
I'm interested in your performance boosts gained from using this guide, especially gains in FPS from the tweaks. A good tool to measure and record this is Skyrim Performance Monitor. When posting performance gains, please include info on you hardware; CPU, GPU, RAM, MB, and operating system. If you have a lot of info including images and graphs in your post, include it in spoiler tags. If you need to know how to use spoiler tags, go to this Nexus wiki page.

Skyrim is a strange beast, it's a game that you can play indefinitely, talented modders produce amazing stuff and it's very hard to make a choice, for example my currently load order was designed to be a light version of my previous one, but now I must merge my mods because I reach out the limit of 255. But if you want to appreciate this game, you must tame this beast, if you don't take time to do this, it could be a very frustrating experience.

This guide is based on information from SoT, STEP, Nexus and Boris' forum and personal experience.

It took me several hours to compile all that stuff for your convenience :), I did it because it's very hard to know which informations are up-to-date or not despite my experience (I mod all my Bethesda games since morrowind)...

I hope you will appreciate it. If this guide help you, don't forget to endorse :)

Before do anything, save all your skyrim configuration, it's must be your first rules when you mod something :

Always do a backup.

I've got a lot of mods (if i count merged ones near 400) and a lot of 2K texture mod (around 120 gb), with this setup, my game run constantly above 45 FPS in exterior nearly totally stuttering free and i can play without any crashes. I hope it will be the same for you.

Notice: As says before, it's a step-by-step guide, you can use some tips independently but if you want to gain full enhancement, you need to follow every part. For example don't take my enblocal.ini without reading how to well configure it nor well configure your skyrim's ini.

I am not fluent in English because it's not my native language, so i did my best but i know it is far away to be perfect, so be tolerant. I apologize in advance for your headache after reading this guide ;).

Any critic is good if it is constructive (and if you do it kindly, it's better ;))

For Reference this guide was tested on :

  • CPU: Intel Core I7 3770K
  • RAM: 8 Go
  • GPU: Nvidia GTX 970
  • SKyrim on SSD (a standard one by Intel)
  • Skyrim is in Fullscreen Borderless windows mode with a resolution of 2560 x 1080
  • Windows 7 Pro 64 bits
  • Standard Drivers from NVIDIA 364.72

1.Prepare your PC

It seems stupid but, If you want a stable game you need a stable system.
Like I say before skyrim is very sensitive, a lot of small software can have bad interaction with it.

Check and tweak
  1. Do a Virus scan with a good antivirus (you can use Bitdefender online. it's fast and reliable)
  2. Do the same about malware with a tool like Anti-malware by Malwarebyte (use free version, you can run it one times by month).
  3. Install Glary Utilities and do a "One Click Maintenance", you can use advanced function if you know what you do to check health of your system, remove software, disable automatic running app. This software is a swiss army knife, use it (do backup when asked).
  4. Defragment your hard drive (you can use windows tools or another one), you can perform this maintenance one time by month. If you have a SSD, Defragment can be harmful because it can reduce your SSD lifetime. You must use a software especially for SSD, i suggest you MyDefrag (because i use it ^^), it's more an optimization than a defrag.

If you use Avast Anti-virus, do a favour for yourself, and replace it by Avira Antivirus. Protection is better, instead of Avast, you can exclude folder AND processus and it don't create a hook on your game process. Why they did that ? I don't know, but they did it, and it can lead to issues especially with ENB.

Set up your PC

If you use a nvidia card, grab nvidia-inspector, run it, click on the tools icon, select "Elder Scrolls V: Skyrim" profile, and set it like picture below (or grab my profile in download section)

I'm sorry for AMD/ATI user, I don't have it, so i can't post setting but I think you certainly have same option maybe with different name, if someone give me a screenshot, I add it.

About VSYNC: My game seems more smooth with this setting, it could not be the same for you, but you need to remember one rule, you must have vsync enable, through game, ENB or driver, it not a matter, but don't disable vsync.

About Frame limiter : To avoid crazy physics, you must cap your frame to 60 (58 is better) max, you can set it to a lower value, but don't go under 31 to avoid longer loading time, if you use ENB to limit your FPS, it's raise the limit to 35 when you load automatically.

  • Don't install Skyrim in Program File (you can move it after installation, follow these instructions)
  • Disable your Steam overlay for Skyrim
  • add an exception to your skyrim and mod organizer folder in your anti-virus
  • if your antivirus can ignore processus from real time monitoring, exclude : skse_loader, enbhost.exe and TESV.exe

A lot of anti-virus think skse's dll or enb are bad, because they try to inject some code in your gaming process, but we know it's good for our skyrim ;). So let them do their job ;)

Before playing :

Set your anti-virus to silence/gamer mode to avoid popup message or alert during your play.

Application with overlay like EVGA PrecisionX 16, MSI Afterburner, Avast antivirus (again^^), EMET, D3D Overrider, Razer and Logitech utility (not exhaustive list), can have bad interaction with ENB, so close it before playing, don't forget to disable your Steam overlay too.

2.Useful software and mod to stabilize Skyrim

List of useful software (don't forget to endorse their respective author) :

  • USE A MOD MANAGER, my preference is Mod Organizer, Easy to learn, useful and powerful, what else ? ;), I stongly suggest you to read documentation.
  • Use LOOT to ordering your mod, you can nearly blindly trust it. Don't forget to read mod description author notices important information about load order, you can add your own rules to LOOT to ensure respect of Modders' indication.
  • Install Wrye Bash. We will use it to create a bashed Patch later.
  • Install TES5edit, We'll use it later and it's a useful tool to check interact.
  • Install SkyrimTools by Mark Fairchild, it's a very handy tool to clean & repair your save if you need it
  • Install SKSE, last version (installer version is the easy one). A lot of mod use it and it includes Sheson memory Patch
  • Install Crash fixes by meh321 and SKSE Plugin Preloader

Follow this procedure to install SKSE correctly with MO :


Configuring SKSE's INI (include in my package):

Edit you SKSE.ini in "Skyrim folder"\Data\SKSE (create it if you don't have one) :

;fix for problem with overlay texture like tatoo

;Skse try to clean unused script, can't harm anything 
;show missing esp when you try to load a save

Configuring Crash fixes by meh321

This fix replace completely SSME and SKSE Memory patch, and improve drastically how skyrim manage memory.
Thank you is not enough for this amazing tweaks, please don't forget to endorse this mod.

  1. First extract SKSE Plugin Preloader, copy d3dx9_42.dll in your skyrim folder (where you found TESV.exe).
  2. Then Install Crash fixes by meh321 as usual SKSE plugin
  3. Check if you have a file named named "CrashFixPlugin_preload.txt" in Data\SKSE\Plugings (beside CrashFixPlugin.ini and CrashFixPlugin.dll), if not, create it.
  4. Open CrashFixPlugin.ini, and set UseOSAllocators to 1
  5. That's all

Special instruction for windows 10 users : (Thanks to  macrocosm144)
Windows 10 could block Crash Fixes' dll which prevent skyrim to be launched.
to avoid this problem, you need to follow these steps :
  1. Right click on the dll file.
  2. Select Properties
  3. Click on the General tab in the Properties window.
  4. Click on the Unblock option next to the Security detail which says “This file came from another computer and might be blocked to help protect this computer.”
  5. Windows might display an Access denied message box here, provide Administrator credentials if this box pops up

Notice: If you have problem take a look to troubleshoot section.

A very good tutotrial video by Tonycubed2 about how to configure it (more detailed) :

If crash fixe doesn't work for you (yet), follow these instruction to setup your skse :


Very Useful mod (don't forget to endorse their respective author):

3.Prepare your game

If you just do a fresh install of skyrim, download my INI files and use them as a base for your configuration, all following tweaks are already included.

If not, take some time to clean them, a lot of tweaks are out of date and can be harmful.


Don't mess with iRadialBlurLevel set it to 0 or remove it.

Some ENB authors ask you to change iRadialBlurLevel
But changing iRadialBlurLevel to anything other than the default may induce CTD. This setting is often erroneously placed inside SkyrimPrefs.ini, even by the Skyrim Launcher, that why a lot of people think that it's okay to change it. But no...

remove :


all section
all section

Don't mess with your ugrid and cell setting, use default, and learn how to install DyndoLOD instead :

uExterior Cell Buffer=36

If you already tweak these setting and start playing with them don't change your value except if you use Stable uGridsToLoad by Altimor, if you can don't use it, this plugin have known memory corruption problem.

Restore papyrus default setting :


;you can raise a little previous value, and only this one, but don't go above 800


;Don't activate your papyrus log, a lot of error is irrelevant and it's a resource hog


;if you need to enable it for testing set the 3 values above to 1

Add or set these line :

Avoid lightning pop-in.


It's avoid missing Esbern's voice bug and prevent problem with TES5Edit or other programs that don't read all the Skyrim vanilla BSAs.

sResourceArchiveList=Skyrim - Misc.bsa, Skyrim - Shaders.bsa, Skyrim - Textures.bsa, Skyrim - Interface.bsa, Skyrim - Animations.bsa, Skyrim - Meshes.bsa, Skyrim - Sounds.bsa
sResourceArchiveList2=Skyrim - Voices.bsa, Skyrim - VoicesExtra.bsa

Disable buggy bmp screenshot and enhance shadows transition


Disable all autosave, autosave can occurs at bad moment and could lead to corrupt savegame or CTDs

If you are like me and forget to save all the time, I strongly suggest you to use SafeAutosave and disable all autosave option in Skyrim settings.

In skyrimprefs.ini

With enb you don't need 8K shadow (the purpose of this guide is smooth gameplay no screen archery ;), and shadows is a ressource hog too) with a good enb you can use these setting :
;Raising previous value made shadows more blurry but an aura effect appears around characters, stay between 1 and 5

;if you raise these two previous values, you increase distance of shadows popping but in counterpart nearby shadows are ugly.

;you can try with 1024, 2048, 4096 or 8192, but 2048 is enough
; if you use only ENBOOST whithout graphic enhancement, you can use fShadowBiasScale=1.0000 to reduce shadows stripping

;Remove iRadialBlurLevel (see explanation above)

;Higher value induces micro-stuttering even you have a powerful rig, it's an engine limitation (detail here), very noticeable in 3rd person view

Important : Follow these guidelines to clean your ESM update.esm, Danwguard.esmhearthfire.esm, Dragonborn.esm

4.Modding good practices & Clean save procedure:

Now you've got a clean base setup, you can add some tips from the section below to your INI, and install all your mod.

  • Removing some mods will break your game, regardless of how careful you are or what procedures you use. Removing a scripted mod is always extremely risky, as is any quest mod or mods editing mechanics that may be active at the time. Removing a mod should always be a last shot at troubleshooting, never something to do simply because you decide you dont like the mod any more, if you can, just disable it in game.
  • If you can't disable it, use a dummy ESP to preserve your load order, you can found one in the file section.
  • Read carefully the mod's installation procedure, warnings and FAQ, before installing a new mod, even it's annoying.
  • Be wary, don't use outdated mod without checking the comments to be sure to known if it could create problems.
  • You can find useful information in the Dangerous Mod Masterlist can be found here and here maintain by Nazenn, it's a community driven guide, fell free to contact him through Nexus, Reddit or Steam about unstable mod if you think it's revelant to add them to this list or if an information is out of date.
  • If you use mod organizer, it's a good thing to create multiple profile to test your mod.
  • Always do a save before installing a mod, if you've got a problem at least you can use this save.

If you need to add or remove during a mod your playthrought follow these steps (but try to avoid that):

  1. To speedup this procedure i suggest you to install No Boring Sleep-Wait Menu by Humbro8282
  2. Ask at your follower to wait you outside
  3. If you have "needs mod" like ineeds or RN&D don't forget to disable it to avoid death by starvation ^^
  4. Disable all active effect: Open console (²) and type dispelallspells, it's also remove vampirism and lycanthropy, so you must reactivate it with console when this procedure is finish
  5. Store your inventory in a permanent storage (like in a player home, if you are homeless you can found a list of safe location here
  6. Save your game in a new slot or type save "before uninstall my mod"
  7. Quit skyrim
  8. Remove your mod (desactivate esp and remove file, restore original file, more easier if you use a mod manager like Mod organizer)
  9. Enable a dummy esp (download section) at the same place to preserve your load order and to avoid to break link between active mod and script.
  10. Load your save, Click yes when the warning windows about missing esp pop
  11. Wait until all your mod is loading
  12. Ask you follower to wait you but not in the house you are
  13. If you are homeless, or if your home have NPC, Open you console and type coc qasmoke in the game console. Note that if you pick up or open or use anything in here it creates savegame corruption and possibly CTD, so DON'T TOUCH ANYTHING
  14. Open console and type tfc
  15. Wait 31 days
  16. Open console and type tfc
  17. Save your game in a new slot or type save "after uninstall my mod"
  18. Quit
  19. Restart skyrim
  20. Load your save
  21. Open console and type pcb
  22. Open console and type coc riverwood, you can choose an another sell or go directly to your home if you know its cellname.
  23. Do a new save
  24. Quit
  25. Open your save with SkyrimTools
  26. Go to the "Clean" menu and select "Show Unattached Instances". This will filter the list and show only the script instances that aren't attached to anything.
  27. Go to the "Clean" menu and select "Remove Unattached Instances".
  28. Save to a new file.
  29. Load your savegame in Skyrim
  30. Finally you can play, don't forget to requip your stuff ;)

5.Avoid Mods conflict with a Merged & bashed Patch

A lot of people know Bashed patch, but before you create it, i suggest you to avoid a maximum of conflict in two minutes.
(if you have mod that use dynamic patch like skyproc, you must run it after creating these two patch)

Create a Merged Patch:

  1. Launch TES5Edit (if you use mod organizer you must launch it through it)
  2. if you use skyrpoc mod, or any dynamic patch (like bashed patch), you must deselect them
  3. if you use a NPC appearance overhaul, Merged patch could cause gray face bug, deselect it if you have this problem.
  4. Select OK and wait full loading (it's take some time)
  5. When loading is finish, you can do a right click on your mod list
  6. Go to "Other" menu, click on "Create Merged Patch" (see picture below)
  7. Click Yes on next message (Ignore warning that says TES5Edit don't support merged patch for Skyrim , just do it ;))
  8. Name your patch TES5Merged without extension (see picture below)
  9. Wait until completion, expand your new mod (Click on the small +)
  10. Do a right click on "Leveled NPC" and remove it, do the same for Leveled Item (see picture below)
  11. Do a right click on your new ESP and click on clean master
  12. Close TES5Edit, don't forget to save and activate your mod
  13. Your mod must be at the bottom of your actual load order

 Name it TES5Merged (not TESVMergedPatch), It will be properly managed by LOOT.

Now, we can create our bashed patch :

  1. Install Wrye Bash
  2. Launch Wrye Bash
  3. Right click on "bashed patch, 0.esp", and select "Rebuild Patch".
  4. At the "Deactivate these mods..." message, click OK.
  5. Select the boxes next to "Merge Patches", "Import Names", "Import Stats", "Tweak Settings", and "Leveled Lists".
  6. Next click [Build Patch]
  7. Activate it and place it after your Merged Patch

Now if you have mod with dynamic patch like DyndoLOD, ASIS, Perkus maximus or Dual Sheath redux, you must run it.

NOTICE: As all automated tools, it can do stupid choice, so I suggest you to open them in TES5Edit to ensure you that everything is good.
Errors in these patches can't harm your game but it could lead to undesired effect.

6.Now you are ready to install your ENB or ENBOOST

First, i suggest you to use a manager like ENB FXAA SweetFX Manager and Remover to manage your configuration. it's very useful to save your setting or clean your skyrim folder when you want to try a new preset.

Before choosing an ENB, go here and check your rig, ENB needs a configuration equivalent or superior than recommended requirements.
So if you can't reach it, you need to use only ENBOOST or a very light one.

I test my setup with various ENB, all of the one works with these setting :
A Bleak Vivid Weather Enb, Performance friendly with a dark atmosphere vibe.
SkySoul Final by Charlotte JC is amazing, I suggest you to test it, it works very well with vivid weather or purity (it's a high end ENB with heavy effect, check your configuration before)
ViVid Weather ENB A good preset from MangaClub
ViVidian ENB same as above, very good light effect, a lot of choice (performance and mod compatibility), compatible with all big weather mod.
Phinix Natural ENB (Set timer resolution may lead to CTD with this one). Good balance between graphics enhancement and performance, compatible with CoT5 and NLA.
The Baltic States ENBs Nice preset for Vivid Weather
DarkLight ENB Light Preset with nice light effects and contrast. performance friendly
All Mobiusbelmont's presets are very good
Natural Lighting Vivid Atmospherics, Very nice and performance friendly, I use it now.

Read carefully the installation procedure about needed mod or software. Like a lot of thing, it's very simple if you read the manual ;).

Installing ENb file is pretty straight you just need to :

  1. Copy ONLY the d3d9.dll and enbhost.exe from the ENB Wrapper folder to your Skyrim folder
  2. Copy the contents of the preset archive to your Skyrim folder
enbocal.ini and skyrimprefs INI edit for ENB users

That's the setting i use (tested with all ENB listed above) :

Edit your skyrimprefs.ini set or add settings below:

//it is not an error Skirym AF and ENB AF are cumulative and have a very low performance impact.

In enblocal.ini








//No need of any Vsync if you use borderless mode (recommended). If not prefer driver's features.

// Set EnableFPSLimit to false if you use Nvidia-inspector or other GPU software to cap your FPS (recommended)



// No need if you don't have parallax texture
// No need if you use SMAA
// No need if you don't have parallax texture

enblocal.ini for ENBOOST users


Important : Due how new crash fixes works, you must set ExpandSystemMemoryX64 to false.

As Boris says in this comment :
Just want to confirm that ExpandSystemMemoryX64 have it's own goal and not "same" thing. Because of very bad memory allocation code in most games, fragmentation greatly decrease amount of available memory and with ExpandSystemMemoryX64=true this issue partially fixed. It's not about amount of free memory, but how many big enough blocks can be allocated till game die from out of memory error. You may have 2 gb free memory, but unable to allocate even 1 mb buffer. This is not the same as fragmentation of hard disk drive, which just reduce performance.
DefaultHeapInitialAllocMB and ExpandSystemMemoryX64 are incompatible with each other just because OS and other software may put various crap in virtual address space (fragment it) and Sheson patch (SKSE now) do not test if it possible to allocate such big memory block, even that i warned authors about this issue very long time ago. You may blame ENB, but it's the fault of patches which MUST to try preallocate memory first and reduce size if failed. Finally, get rid of s*** running, every software these days trying to inject something in to game process, the chance to get big memory block is lower and lower every year

This fix defragments memory to increase amount of available memory that can be allocated to memory block, crash fixes bypass the use of memory block, so it's not needed anymore.

Very important :

If you experiment crash with windows 8/8.1/10, try to install DX9 runtime.

ReservedMemorySizeMb=64, this value can be change but it's must be a multiple of 32.
I suggest to start at 64 and try raise it until you get rid of all CTDs

Maximum value is 1024, but bigger number is not better, try to keep the value as low as possible. If you have too many CTD raise it, but do it step by step (for example: I use nearly 400 Mod, meged to bypass esp limitation, and I use 96) .


Windows 7 : This value depend of your OS and your VRAM, grab the tools provided by Boris VramSize and launch VRamSizeDX9.exe.
Take this value minus 170Mo for windows 7.

Windows 8/8.1/10 : Sadly, Windows version above 7 have a problem to manage DX9 game memory correctly , maximal value is 4064 Mo. If you set an upper value, you will get a CTD when you will reach the limit of 4064. (You don't need to minus value, just use VramSizeDx9 value)

VideoMemorySizeMb  sets the total memory that will be used for the ENBoost dynamic memory allocation. Not the total of VRAM that will be used by Skyrim engine.

In my case, i use Windows 7 pro 64 bits, i've got : 7808 - 170 = 7638

Trust Boris tool, ENB is his creation, he knows more that anyone how is tool works.
Don't trust any magical values you can find on any enb configurations.

These setting manage process priority and add some stability fix, but you can experience massive fps lag, set it like below


DataSyncMode=0 and PriorityMode=0 is the recommended setting and should always be used, unless If you have CTD or problem when you load a save, set it to :

PriorityMode=3 and DataSyncMode=2, according to Boris' advice, it is the best balance between fix and performance for Nvidia users and
some ATI/AMD users

or to :

DataSyncMode=1 and PriorityMode=0 is mostly the best balance for AMD/ATI users.

Be warned that you will experience stuttering and lag if you use PriorityMode=3 and DataSyncMode=2 (or DataSyncMode=1 and PriorityMode=0), and it should only be used as a last resort.

You can change it mid-play so you can enable it temporarily, and set it to 0 & 0 when you no longer need it.

If you want to use SWEETFX preset, RCRN or software SMAA, you need to set ProxyLibrary setting.

For example:
If you want to use RCRN with ENBOOST :
  • Follow their installation instruction
  • before copy d3d9.dll in skyrim folder, rename it to d3d9_RCRN.dll
  • EnableProxyLibrary=true
  • InitProxyFunctions=true
  • Set ProxyLibrary=d3d9_RCRN.dll
  • That's all

It's exactly the same way for other injector like Sweetfx or SMAA.

Notice: If you use ReShade, you must set InitProxyFunctions to false

7.Special instruction for Skyrim Reloaded - SKGE - SKGE's users with ENBOOST

Skyrim Reloaded - SKGE is an SKSE plugin that mainly modifies the rendering pipeline, adding new features and providing screen effects not supported in the vanilla game. Instead of using an injector like sweetfx or ENb it uses game engine.

For the moment, it not override all effect in game like you can do with sweetfx or enb, but this solution is very performance friendly and compatible with every mods. At this moment I use it with a sweetfx preset to enhance stuffs who are not managed by SKGE yet.

Installation are pretty easy :
  1. Download main archive
  2. Unpack it like other SKSE plugin
  3. Download my enblocal.ini, set it for ENBOOST (cf previous section)
  4. Set speedhack to false (This part has nothing to do with ENBOOST, source)
  5. That's all !!

If you use mods who alter camera, you must edit Data/SKSE/Pulgins/SkyrimReloaded.ini and set FoV = 0 and CameraMode = 0
If you want to use borderless fullscreen, set bFull Screen to 0 (skyrimprefs.ini) for windowed mode and SR will automatically use borderless mod

If you want to take advantage of SKGE and ENB features, use Fusion ENB Preset by DarkShenron, it is a very nice ENB preset tweaked to work with SKGE.

After that, you need to read SKGE documentation to configure or enable every features.

If you want to enable parrallax, you need to follow these instructions :

Edit your skyrimprefs.ini

Edit your enblocal.ini : 



Download my enbseries.ini (every effect are disabled except stuff needed by parallax)

That's all !

Note: This part will be updated when a new version will be released.

8.Last thing to do to avoid stuttering: Optimize your texture.

If you just want a smooth gameplay and don't do screen archery, you don't need 8K texture or 4K. With a good ENB 2K is a very good balance between Quality and Performance.
I strongly suggest you to cap your texture to 2048, no need to go under, performance gain is minimal (Except if you have less than 1Go Vram, cap it to 1K)
Even you don't want to reduce your texture resolution, you can optimize it by add mipmap file and compress it if needed.

To do that you need this tool Optimizer Textures, and grab the ini in the file section.
I add some exception to avoid errors and to ignore parallax file (they don't like optimization)
Use it on each mod, or use it through mod organizer (add it in the executable list, and choose your texture directory in data, after create a new mod based on the content of "Overwrite") when you will have finish to install all your texture mod but before run DynDOLOD if you use it.

I suggest you these settings :

Mipmaps setting and Resize patterns is the most important, don't go below 16x16 except if you want a Tetris game instead of skyrim.

9.Icing on the cake

You want to grab a little more performance ?

To grab a little more power and reduce micro-stuttering you can use these two small utilities, they help to optimize how windows handle your processor:

Windows System Timer Tool, Run it, set timer to 0.5 and minimize it, click on unset timer to get back your default setting. (Vividian ENB 7 works well with it, but I notice CTD with : PHINIX ENB 2.0.27, Tetrachromatic ENB (thanks to ff7legend for the report, more feedback is appreciate).

ParkControlFree, download version according to your system (32 or 64 bits) and install, Launch Parcontrol, select the Bitsum Highest Performance power profile, click on Apply. When your game session is over, launch it again, and set your usual power profile.

From website author FAQ :
"CPU core parking and frequency scaling can have a dramatic impact on real-time performance of bursting loads like audio/video, gaming, VOIP, and more.
That is a big reason we have made such a ‘fuss’ over them. It was nice to be ‘vindicated’ by Intel, who has moved core parking control to the hardware in new CPU generations because the OS’s management was so sub-optimal. As long as they retain the ability to disable core parking, and I’m sure they will, it should be a good change. Microsoft seemed to focus entirely on battery life in recent years, leaving performance to suffer, particularly for desktop users."

When Skyrim runs, CPU stressful situations often occur over a few nanoseconds, which would be fine if Windows could unpark your cores instantaneously, but it's not the case. Unparking your cores indefinitely will increase system stability, it will also boost performance based upon the situation.

It's not an overclocking and it's don't really reduce lifetime processor but it's may drain your battery faster on a laptop.

If you want to deeply understand what these tools do, please read carefully the description on respective author site.

Now, we will configure skyrim's cpu affinity to avoid a misuse of hyper-threading :

You don't need this tip, if your CPU is not hyper-threading.

If you don't know:

intel processor : you can go here, and check if your processor have it (do a search with your processor name, in performance section, check number for core and thread, if you have double thread than core, it is hyper threading).

AMD processor : I'm sorry i don't these processor very well, if you a fx processor, you can use this tips, for others, sincerely, i don't know.

Skyrim's engine works very well in on a multi-core CPU but it doesn't made difference between logical core (Hyper-Threading) and physical core.

These steps will explain you how to force skyrim to assign one process by core. The purpose of this tweak is to use only one real core, they are coupled by two (Core 0&1, 2&3,4&5, etc...), if your processor is old, Core 0 is the real one, core 1 a logical one, Core 2 - real, Core 3 - logical etc... Last processor generation uses only logical core, these explanations are designed to work with old or new processor.

This step will show you how many CPU cores you have, and how to figure the hex value to use at step 3 below for the CPU(s) you want to run the application on.

NOTE: If you should need any assistance with this step, then please feel free to post. I'll be happy to help.

A) Open Windows Task manager (CTRL+Shift+ESC) in more details view, click/tap on the Processes (XP, Vista, Windows 7) OR Details (Windows 8) tab, right click or press and hold on any process in the Name column, and click/tap on Set affinity. (see screenshot below)

NOTE: This will show you how many CPU cores you have. I have 8 CPU cores numbered from 0 to 7.

B) For how many CPU cores you have will also be how long the binary number will be. Since I have 8 CPU cores, the binary number will be 8 zeros 00000000. Each zero in the binary number represents a CPU core number from right to left. In my case with 8 CPU cores, the far right 0 in the binary number will be for CPU 0, and the far left 0 will be for CPU 7. (see screenshot below)

C) For each CPU number you want to run the application on, replace 0 (off) with 1 (on) in the binary number for the CPU numbers.

For Skyrim, if I wanted to run the application only on CPU 0, CPU 2, CPU 4 and CPU 6 then my binary number would be changed to 01010101. (see screenshot below):

D) Go here, and type your binary number from step 1C above into the Binary field. This will convert the binary number to a hexadecimal (hex) that you will need to use at step 3 below.

For example, with my 01010101 binary number, I get a hex value of 55. (see screenshot below)

 If you use mo, you need to edit SKSE shorcut to match to image below :

3. Replace 55 by your setting and update path accordingly to your setup.

That's all

If you don't use MO

You will need to create a shorcut to launch your game, do a right click on your desktop, click on New and Shortcut

3. Type the command below into the location area, and click/tap on the Next button.

cmd.exe /c start "skse" /affinity 55 "E:\Steamfast\Steamapps\common\skse_loader.exe" -forcesteamloader

3. Replace 55 by your setting and update path accordingly to your setup.

4. Type any name you would like to give the shortcut, and click/tap on the Finish button

That's all

I'm sorry for NMM's users but I don't use it so I can't provide any screenshot or explanation, if someone send me these informations i will add it.

10.List of useful tips

These tips is already in my cleaned INI.


11.Avoid strange FOV or HUD Problem with unsupported resolution or very wide screen

  1. Edit your skyrimprefs.ini and set "iSize H" and "iSize W" to match your resolution (ex: iSize H=1080 iSize W=2560 for me)
  2. Install this little utility Flawless Widescreen (works for a lot of other game)
  3. Activate the skyrim plugin
  4. Go to setting menu, choose configuration then Display detection; tick Display Detection override
  5. Configure as picture below (Update to match your resolution)

Enjoy :)



You still have stutter after follow all the step of this guide, even when you disable graphical enhancement ? (or you are a ENBOOST only user)
If you use ENB's frame limiter, disable it and use the one from your drivers.
Check if you have reduced Reserved Memory to minimal value.

If it still stutter :

Try to downgrade your enb to V0.279 or 0.292, if stutters vanish, sorry, you are unlucky.
Don't forget to check if your preset support older version (an easy way is to check if they use dawn / dusk features), most of them works out of the box with 0.20x series.

Don't forget to bring feedback and post your configuration in comment section

A little bit of explanation : Boris have stated that some people can encounter unknown problems which make your game stuttering when you use ENB 0.30x series.
Technically these version are very close and code modifications shouldn't induce problems, but it is a fact : it occurs for random users with no explanation.
Sadly Boris can't reproduce this on his side so for the moment it is the only way to solve that.

If you want to check by yourself, you've got a lot of posts on ENB forum about it.

Crash when you load your save from main menu:
  1. Open console
  2. type coc qasmoke
  3. Load your save

If it works or if this problem is recurrent, you can use this very clever mod: Continue Game No Crash by Utopium which do the job for you.

Suddenly, Skyrim crash when you save :
  1. Load an older save which hasn't CTD save glitch.
  2. Create a new save through main menu
  3. Open console (use ²) and type player.kill
  4. Load your latest save (the one which had CTD glitch)
  5. Type in player.kill
  6. after loading, try to save (Quicksaving is enough)

RS children / modded children and XPMSE users :

Big FPS drop when you are in a crowned area with kids arround :
Install XPMSE Skeleton for RSChildren by xp32 - Groovtama - Ranaline - DetectiveToaster to solve this problem.
If you don't use RS children, you need to rename file and replace original skeleton by these ones.
Thanks to Shubal for this fix

Crash fixes :

UseOSAllocators=1 and crashing when touching sliders in character creation or otherwise :
Set AlignHeapAllocate=1 in CrashFixPlugin.ini, downside is increased load time and increased memory usage. (Setting that I suggest by default)
NetImmerse Override is well known to have problem too, it you use it, replace it by racemenu.

UseOSAllocators=1 and crashing on game startup or loading save or shortly after:
Set ExpandSystemMemoryX64=false in enblocal.ini (Setting that i suggest by default)

Game says message box "running out of memory" and crashes:
Set ReduceSystemMemoryUsage=true in enblocal.ini (Setting that I suggest by default)

Game says message box "running out of memory" and crashes and ReduceSystemMemoryUsage=true :
  1. Edit CrashFixPlugin.ini and set CustomMemoryBlock=1
  2. Take a look at crash fixes in-game report by opening skyrim console (with ²)
  3. In CrashFixplugin.ini, increase or decrease CustomMemoryBlockTotalSizeMb until highest memory block usage's value is around 85% - 90%

How to determine the source of crashes from unkown exception addresses ?
Read the guide written by Overlord69 about it.

SkyUI retrun you an error code 7 :

In your skyrim.ini :

ReShade :
CTD at startup.
Set InitProxyFunctions=true to false

if you experiment crash with enb wrapper version on laptop equipped with a Nvidia Optimus technology.
  1. Rename your current d3d9.dll (from the game folder) to "d3d9orig.dll"
  2. Copy our d3d9.dll to the same folder (the game folder)
  3. Open NVidia control panel, and explicitly add your game's EXE file to the list of "high-GPU-requirement" programs.
  4. That's it!

Windows 10 users :
Crash fixes is blocked or a message like this : “Windows found that this file is potentially harmful. To help protect your computer, Windows has
blocked access to this file.” when you try to launch Skyrim
(Thanks to macrocosm144 ) :
Windows 10 could block Crash Fixes' dll which prevent skyrim to be launched.

To avoid this problem, you need to follow these steps :

  1. Right click on the dll file.
  2. Select Properties
  3. Click on the General tab in the Properties window.
  4. Click on the Unblock option next to the Security detail which says “This file came from another computer and might be blocked to help protect this computer.”
  5. Windows might display an Access denied message box here, provide Administrator credentials if this box pops up

CTD at start up with an ENB preset with sweetfx
No real solution, sweetfx is not totally compatible with windows 8/10, you can try to replace it by reshade.

TabletInputService induces a lot problem (random crashes, crash at startup, stutter, problem with borderless features), the best solution is to disable it. (Thanks to ibbanez)
Run command promt as Administrator and type :
sc config "TabletInputService" start= disabled
sc stop "TabletInputService"

If you want to reverse :


If you still have totally random crashes after using previous tips, use a timer (or check beginning/end of your logs) to see if the crashes happen every 15 minutes exactly. If they do, it's likely caused by the touch keyboard and handwriting panel service in Windows 10.(Thanks to JackArbiter)
To stop the virtual keyboard service and keep it from starting again, type services in the taskbar, click services, go down to touch keyboard and handwriting service, right click and stop it, and then rightclick>properties and select "disabled" for "startup type."

13.To do list:

  1. Add information about FPS cost for each tweaks if possible.
  2. Add information about FPS cost for ENB effects.

14.Removed Stuff (may still be useful):
