Q. I can't locate the right path where to paste the Engine.ini A. Just press Win + R and copy/paste the following path in the box it will appear if you have Xbox / Game Pass version:
%localappdata%\Sandfall\Saved\Config\WinGDK
or this one if you have Steam/GOG/Other versions:
%localappdata%\Sandfall\Saved\Config\Windows
then hit enter and you will end up in the correct folder where to put the Engine.ini
Q. When I launch the game the modded Engine.ini is automatically deleted or reverted to default one? A. Right-Click on my Engine.ini -> Properties -> make sure the "Read-Only" box is selected -> Apply/OK It's important. If the file keeps getting deleted or reverted, un-tick the "Read-only" box -> Apply -> re-tick it -> Apply/OK Q. When I right click on Engine.ini Properties I have a security warning stating "This file came from another computer and might be blocked to help protect this computer"? A. That's just a warning that tells you the file comes from another PC (mine). It will still work without issues.
Q. My CPU usage is skyrocketing to 100% after the mod A. This is initial shader compilation which may continue in-game even after the initial precompilation loading screen. Wait 4-5 minutes at max to let the game finish it and CPU usage / performance will return normal.
Q. I have noticeable ghosting A. To improve ghosting I highly recommend updating the game's DLSS .dlls to latest DLSS4 version (easiest method: DLSS Swapper) and force the "Latest" DLSS preset via NVIDIA Profile Inspector or NVIDIA App. It will make an huge difference for the better. Also always use the latest version of the mod.
Q. I have the same or worse performance after the mod A. For super high-end PCs the performance difference may be small but you should still notice reduced stuttering, more consistent 1% lows, lower input latency and better visual clarity. For mid and low-end PCs the fps difference may be much bigger on top of all that. If for some specific PC configs you end up with worse performance try deleting shaders cache including the files which end with "cache" located in the "Saved" folder from the above path and open the game again. If you still have worse performance just delete my Engine.ini and on next boot the game will recreate its default one. You don't need to verify the game files or reinstall it to restore it to what it was before the mod.
Q. Will this mod downgrade visuals/graphics? A. No :) "Lossless" means this mod was created with the goal to optimize everything I could in Unreal Engine without sacrificing visuals and/or altering your in-game graphics' choices (except for Chromatic Aberration and Film Grain removal which you can still revert back by changing their described lines within the Engine.ini itself) With improvements to AA, Sharpening, DLSS/FSR/XeSS you should actually have even better visuals after the mod.
Q. Can I use it together with Oblivion Optimiser, Oblivion Ultra+, Oblivion "Uber-Tweaks" or whatever? A. No. Don't mix my Engine.ini with other mods which will do their own optimization tweaks to the engine or they may conflict with each other. You can try each of them separately and choose the one which performs the best for you and only use that exclusively. You can still install any other "non-optimization" mods.
Q. Will this Engine.ini disable Achievements? A. Straight and simple: no. :)
Q. Will this Engine.ini work/load also with future game patches? A. Yes. Just be sure the file is set to "Read-only"
Q. The game crashes when opening it and/or during gameplay after a while A. Make sure your PC is actually stable under sustained load (e.g. you are not using an excessive overclock/undervolt). You can test it using OCCT (launch a 1 hour "CPU+RAM" test, followed by another 1 hour "3D Adaptive" test. If you have even a single error, you need to fix your PC stability first) Another solution if you use Vortex is to open it, go to the game section -> Load Order and click the last button ⛔ on the top bar ("Reset Plugins File") If even doing the above you still crash, try lowering PoolSizeVRAMPercentage=60 (both in [TextureStreaming] and [ConsoleVariables] sections of the .ini), then remember to set the .ini to Read-only again.
Q. I noticed you were extremely fast in creating the mod after the game launched. How? A. The .ini is the result of months of testing also with other UE games. The feedback gathered from all of them made me expand/improve it over time and, yes, it is compatible with all UE games (with minor modifications), that's also why you saw me uploading the mod so fast at the beginning.
I went from an average of 97 FPS without the mod to 111 FPS with it, running the same gameplay sequence (from the start up to the port) — 5800X3D, 7900XT, 32GB RAM, 4K, using XeSS on balanced and Frame Generation via OptiScaler
Works perfect, thanks! A lot of the stutter in cinematics is gone, and the mod increased the performance overall. I Even recomended it to two friends of mine and worked perfect for themtoo.
So I have a different issue that I think may be tied to an engine variables or the like, and its to do with audio. Essentially, only in very select areas/instances, the audio crackles/stutters/distorts, on every audio format I've tried. It's made those particular sections very hard to play as it's legitimately painful to hear multiple times. Was wondering if you know anything about that, since I saw a few Audio-related variables being changed, and also an "AudioQualityLevel" in the game's base ini file? Also will likely just test this mod to see if it helps the issue.
So it did not completely fix the issue, but it did improve it to the point where it occurs much less, is less severe, and isn't painful for my ears, which is nice.
There is no need. Swap DLSS .dll to latest DLSS4 one using DLSS Swapper and force "Latest" preset for it in NVIDIA Profile Inspector or NVIDIA App then use DLSS Quality in-game (it will look much better than native and even better than DLSS3 DLAA)
To reduce/remove shimmering of fine details (like hairs), combine my latest mod with ClairObscurFix

So on this....I am only version 0.0.10 for ClairObscurFix mod due to the cropping issue. Is that version still going to remove the shimmering or do I need his latest?
Hey - I don't seem to get any change at all in my FPS from using this mod..
The weird thing is, I got a 10-15 fps improvement from your oblivion mod, so I don't understand why this one for Expedition 33 is not having any effect for me.
I'm on 9070xt, 5800x, 64gb ram. The only reason for this difference I can think of is that I was able to use FSR natively in Oblivion, whereas in Expedition 33, I am using Optiscaler to redirect DLSS to FSR 4, at DLAA setting.
If you can suggest anything else to try, please let me know!
(For info, I also tried this mod and it also had no effect on my performance.... https://www.nexusmods.com/clairobscurexpedition33/mods/4)
The main difference is that Oblivion Remastered is a disaster, optimization wise, so it benefits much more from my modded Engine.ini
Clair Obscur, on the contrary, is much better in this regard so you will notice less improvements in fps or stability but should still clearly notice improvements in input latency and picture clarity over vanilla.

Try the mod and let us know if it improves.
Thanks for the feedback ;)
Enjoy ;)
This Hotfix addresses the following:
Clair Obscur: Expedition 33 may crash [5283401]
https://nvidia.custhelp.com/app/answers/detail/a_id/5667/
Edit: nvm, still getting crashes :')
Just follow the instructions for installation in the Description and for more info everything is in the pinned FAQ here.
In that case delete the line (and its duplicates)
