S.T.A.L.K.E.R. 2 – Ultimate Engine Tweaks v1.0
Definitive Unreal “Engine.ini” changes with the goal to remove most stutters, improve performance and stability, decrease input latency, improve picture clarity. All with no visual loss.
After many hours of testing, I would like to share my definitive custom “Engine.ini” changes for the game.
My goal was to just include as many optimizations 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 Windows/Steam, whatever folder you will find there)
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.
The initial Shader Pre-Compilation Loading may take longer after the .ini changes, but then the game will be smoother during gameplay.
