Silent Hill 2 (2024) - Ultimate Engine Tweaks
After weeks of research and 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 (except for specific traversal stuttering which is impossible to fix except by the devs themselves), 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%\SilentHill2\Saved\Config\Windows
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.
