S.T.A.L.K.E.R. 2 - Ultimate Engine Tweaks

S.T.A.L.K.E.R. 2 - Ultimate Engine Tweaks (from Nexus Mods, please support the original author).

"After many hours of testing, I would like to share my definitive custom "Engine.ini" changes for the game.

https://www.nexusmods.com/stalker2heartofchornobyl/mods/17?tab=description

My goal was to just include as many optimisations as possible (both for CPU/GPU/RAM/SSD) in order to remove most stuttering, improve performance, reduce input latency and improve picture clarity (by removing Film Grain & Chromatic Aberration) all without any visual loss nor introducing glitches or crashes.

You can directly download my Engine.ini to replace or just copy all the lines below inside and at the bottom of your game Engine.ini, which is located in:



%localappdata%\Stalker2\Saved\Config\WinGDK

or for the Steam version here:

%localappdata%\Stalker2\Saved\Config\Windows

(if you can't see any Engine.ini file in it, just put mine there. To Uninstall just delete the Engine.ini and the game will recreate a new default one)



Please pay attention to some comment lines after ";" which may be related to specific configurations (e.g. VRR usage, VRAM amount etc.), so change them accordingly to your hardware.


If you do not have a Engine.ini file, just create a document and paste the following. Or download the .ini from Nexus Mods.
