First of all, read this all careful, as you will miss some important Information and may get bad experience if you tweak your INIs wrong.

Save your current INIs before you use my different preset INIs. May be you first start opening yours and then choose one from my presets and compare it in Notepad and edit yours. The collection under main files contains all different presets for weak, medium, high and ultra hardware sets. You can find each of them as a standalone download under optional files.

If you're using an AMD Radeon graphics card, use the currently new final release, or even better Crimson 16.x, I'm using 16.7.3 currently and finally all stuttering has been gone, 16.3.x had some bugs, all supporting Windows 10.0 as well already, to continue with your good experiences on the game and graphics and my settings. When you use the new AMD Radeon Crimson Edition, take care you defined the game settings for Skyrim as mentioned before, as adjusting AMD game profiles is different as before with CCC. You are now able to adjust the predefined profiles in the new AMD Radeon Crimson UI.

But keep in mind, that usage of VRAM on Win8 and Win10 is still limited for DX9 games up to 4GB only, not higher as it was possible with Win7. Microsoft Platform Support Team is already investigating this bug, but if they will fix it is not sure, depending on how many users complaining. Details here.

With my settings on Ultra you get up to 62 FPS and usually an average of 45 to 58 FPS, almost more than the mandatory 30 FPS to experience smooth scripting. Even my Low settings for weak computers let you experiencing up to 60 FPS and so a smooth scripting execution.

Make sure your graphics card is set to SuperSampling, as the INI configuration doesn't use MultiSampling as it is usually useless, so it is disabled on the SkyrimPresf.ini section [Display] with iWaterMultiSamples=0 and iMultiSample=0 (same settings as switching this to off in SkyrimLauncher) and you get better graphics experiences without this setting. But you need to set your graphics card Anti-Aliasing Methode to SuperSampling and AA to 8x and option to overwrite application settings (if you use any ENB presets, you have to leave your graphics card to use application settings).

Optional you can set iMaxAnisotropy=1 (setting it to 1 is the same as setting Anisotropic Filtering to off in SkyrimLauncher) on your SkyrimPrefs.ini under the [Display] setting, as the game filter is not optimal, usually filter of your graphics card driver is better, but if you disable the in-game Anisotropy-Filter, you have to enable it on your graphics card settings with level 16x and option to overwrite application/game setting (except you use any ENB preset). If you use my own INIs, you have to do this, as I have switched AF to off on my settings.

When you use one of my presets, watch the INIs special sections as mentioned below on this text and edit it with the values from your own backup INIs, especially the values in regards of your language and graphics device, otherwise it will be reset by default Skyrim in-game configuration.

Remember to change your graphics reference in the SkyrimPrefs.ini under [Display] section (sD3DDevice=) and your display resolution (iSize H / iSize W). Otherwise the game will overwrite the whole INI. You must also check the language setting on [General] section (sLanguage=) in the Skyrim.ini, otherwise the Steam game management will start downloading the languages files for this language.

Mod Organizer and some other mod manager tools like STEP makes and uses its own Skyrim.ini and Skyrimprefs.ini located at Mod Organizer/profiles/your profiles name. So be aware to replace or change the right INIs to get your results.

My recommended graphics mods in install order:

Ruins Clutter Improved by raiserfx
HD Enhanced Terrain by Hritik Vaishnav
SkyFalls and SkyMills - Animated Distant Waterfalls and WindMills by SjoertJansen (don't use it with Purity mod!)

improved LOD trees by Prime8King (don't use if you use SFO, currently there is no compatibility patch)

HiRes Lods Trees for SFO by Mitradis
Enhanced Ore Veins by ClearanceClarence

watch the mod files on several mod recommendations they provide extra mod for nonENB users with similiar effects or patches for nonENB users. I usually use 2k resolution and texture of graphics mods, not more. And finally I use USLEEP and addons. My favorite HDT Animation resource are Knightmare077's and all the references listed on his description page. Havok physics are tied to the games frame-rate, so FPS below 40 or your CPU being stressed tends to cause HDT Physics Animations to behave glitchy. Also FPS above 60 breaks Havok, so make sure you use v-sync with iPresentInterval=1 on your skyrim.ini enabled. If you have a low hardware environment, HDT animations may not be for you.

Additionally I use idle mods like
Pretty Female Idles by Dualsun
Sexy idle Animation by Kamo1
choose one or the other, they both overwrite the same file. Watch the videos on the sites to select your idle style.

And I prefer to use mod recommendations from SkyrimTuner too, even I don't use his ENB presets.

Instead of the above listed texture mods, I used just Purity by Laast and the additional landscape and cities textures only. It is worth to try it out alternatively. And read the hints here. For my own, I just added some texture mods from Gamwich and ramccoid as well the one from ClearanceClarence listed.

Who like to use DoF effects, try DYNAVISION - Dynamic Depth of Field by Gopher and MyGoodEye. For me I discovered this settings are optimal:
Master DoF: Dynamic
Master DoF Strength: 0.7
DoF Strength for Combat: 0
DoF Strength for Interior: 80
DoF Strength for Running: 70
DoF Focus is off with Master DoF = Dynamic; if using Master DoF Static set DoF Focus Method to Sharp with speed setting 1.5.
You may adjust DYNAVISION as you like, in-game using the MCM system that comes with SkyUI 3 or later.
There is a nice video on YouTube where the author introduces his mod and settings.
Make sure you have not switched DoF off in your ini file. If you don't see any effect, open your Skyrimprefs.ini and look for 'bDoDepthOfField'. Make sure it is set to 1.

For some bug fixes (on the game executable) I use the Bug fixes mod from meh321, which may be updated for additional bug fixes in the future.

For game content fixes it is recommended to use Unofficial Skyrim Patches, mainly USLEEP. Most of Arthmoor's mods are also available in other languages to match your game language you use.

There is an Excel spreadsheet on the download section which column 'Activated' shows the install order of all of my current used mods too. You can also see some mods with my comments on the last version 2.0 and earlier under old files, if I discovered not acceptable bad impact on the game. I have started a new game, so the activated mods are on the current version 2.01 on the Excel sheet. Because I use now mainly only Purity mod and textures as well textures form ramccoid and Gamwich, there are less mods activiated, as already mentioned above. The listed German mods on the spreadsheet nearly all of them have an English original available.

There is also an archive with Excel sheets about my old assembled mods, which were active when I made one or the other screen shot. Just go by date of the pics, then you find the latest Excel sheet before pics taken, they include the activated mods on that time.

I have started an article too with change log for my own current SkyrimPrefs and INI settings.

Additional performance and stability is possible using
SKSE 1.7x and memory settings on skse.ini. When Steam game starts it will recognize SKSE and load it. No need for any manipulation on file names or anything else.

If you don't want to switch your uGridsToLoad settings very often, but you experiencing CTD or any other instability, use Crash fixes mod by meh321. You need to have SKSE installed too.

Install Safety Load if you have an infinite loading screen, CTDs or game freezes. The mod fixes a bug in memory allocation which cause deadlocks. You will need it even you have SKSE with the memory patch installed. SKSE memory patch hides the deadlock problem to occure earlier, because it allocates a larger memory block. If you don't suffering of CTDs, game freeze or infinite loading screen then you don't need this. If you use Crash fixes mod from meh321 and the setting UseOSAllocators=1 with SKSE Plugin Preloader by meh321 and sheson, you don't need Safety Load mod anymore.

If you going to switch your uGridsToLoad settings, you may use
Stable uGridsToLoad Cell Stabilizer which enables you to easily change your uGridsToLoad settings without damaging your saved game file. But be aware that if you save a game after you have altered this value, the new value will be incorporated into your saved game. This is worth noting because the game only allows you to load a saved game with a higher uGridsToLoad value in your INI. This means if you lower your uGridsToLoad value again, you won't be able to load up the saves which used the higher value. My INIs contain settings for uGridsToLoad=7, if you want to use lower value, you will ease the scripting engine, as scripts are not starting so early as with higher values too. This setting is known to have impact on performance regarding scripting, that is why I could level this by higher values for fUpdateBudgetMS in the past, but this became obsolete in the meantime too.

You may need some or several starts of Skyrim to make the Stabilizer work, give it a few tries.

Keep in mind to watch [Grass] section on Skyrim.ini regarding iGrassCellRadius=3 (which needs to be uGridsToLoad value -1 /2 for stability mandatory).

With my newest Skyrim.ini settings since version 1.9 you don't realy need a high uGridsToLoad setting. Compare on your own and make a screenshot with a lot of far distance objects, close the game, open Skyrim.ini under [General] section change uGridsToLoad=5 and uExterior Cell Buffer=36, save the INI, start your last savegame, make again the same screenshot, and close your game, and compare both pics. If you like it, you can stay with this settings, but consider what I said a few lines before. BTW, when you want to use uInterior Cell Buffer=, it should always be the half of uExterior Cell Buffer=.

Only use Crash fixes mod by meh321, if you can't load a savegame after you changed your uGridsToLoad settings, it will
work with Stable uGridsToLoad Cell Stabilizer enabled, don't use both. But keep watching on orphaned scripts with Save game script cleaner before and after every switch. And use FPS Counter or if you already use the newest Steam Client, you can enable integrated FPS Counter of the Steam Client, to make savegames at close to 60 FPS, sometimes you have to turn around and find a view to get this FPS. This makes sure you get the closest best performance when loading the savegame again on other uGridsToLoad settings. Best to be done in Cities or Houses.

If you don't use mods with a lot of scripting or none or only one follower, you can change the Papyrus setting in Skyrim.ini to default if you use one of my INI presets before version 2.x.


Except the Skyrim Project Optimization, I used nearly all of the recommendations from
Skyrim Stability Guide, Skyrim Graphics Guide and Real uGridsToLoad Solution and more.

Additionally you need ENBoost (currently v0.308) when you use UseOSAllocators=1 setting on Crash fixes mod by meh321, then you must use it just for this setting "ReduceSystemMemoryUsage=true", only to improve memory management for a better graphics experience. Read careful which files you need and what you need to configure in the enblocal.ini, to get the best experience on your graphics. There is no need to change anything on my INI presets provided here. If you start the game now, on the loading screen you will see a red line saying: PATCH SPEEDHACK ENBoost turned on in enblocal.ini, graphics modification disabled.

Use Boris Vorontsov's new tool VRamSizeTest run the VRamSizeDX9.exe to display the correct value for VideoMemorySizeMb for your enblocal.ini. and reduze value about 170 if you running on Win7 from the value provided and use that value. Windows 8/10 users reduze by 350.

With my own settings I use
uExterior Cell Buffer=64
uInterior Cell Buffer=32

with the hardware I am using currently: Intel Core i7-3840QM, 16GB RAM, AMD Radeon HD 7970M Crossfire, there are no CTD, and the system became stabile even when FPS drops under 30.


This can be different with other hardware, driver and ENBoost versions. For me I get better results in the meantime without ENBoost and at certain places up to 30% better FPS. If you missing stability on your game, try the mods from meh321.

If only running ENBoost without an ENB preset enabled, it is recommended to set ForceAnisotropicFiltering=false on enblocal.ini under [ENGINE] section when using a AMD Radeon graphics card, as it may cost less FPS to force via Crimson Radeon game config than running AF via enblocal.ini, and the result is identical. If you using a Nvidia graphics card, the setting should stay as ForceAnisotropicFiltering=true.

One thing to mention regarding crashes. During my long game play I discovered, that mostly crashes, especially when fast travel, the crash is occurred because of much scripting, because Vampires or Dragons are waiting at destination. I discovered when just choosing an interior area, you will be able to get to it, and you will recognize, when you leave this interior, there are some Vampires or Dragons waiting ;-)

Use load order from LOOT. Check the thread on LOOT and get the newest version, but read the release notes if you upgrade.

You have to travel a while through Skyrim until you get all advantages and all texture well loaded from your new settings.

If you want to use ENB presets, use Stakado Cinemascope ENB, Natural Performance ENB, Rudy ENB, NLA, RealVision, Millepon Diamond ENB, Kalicolas ENB, Saturn ENB, LuciEN ENB or AIR ENB.

Just change the settings on my INI presets according modders recommendation in regards of


if necessary. As the above settings should already be set on all of my INI presets by default.

Also when ENB preset and DoF enabled, it is sufficient to use Skyrim.ini settings on

uExterior Cell Buffer=36
uInterior Cell Buffer=18

And make sure you edit the right INIs, when you are using a mod manager.

You can use Skyrim INI Manager to manage your INI settings and presets.
