Lowering your resolution provides the largest performance increase.
: Reduces input lag. It forces the CPU to process frames immediately rather than queuing them up, making mouse movement feel significantly snappier. Locking the File to Prevent Overwrites
: Change ShadowQuality , CasingShader , and DeferredAmbientQuality to "low" or "off" .
In this 2026 updated guide, we provide the definitive, safe, and most aggressive low-spec configuration file available. We will walk you through the download, the manual tweaks, and how to install it to achieve
If the config file isn't enough, try these additional methods:
<GamerProfile> <SoundProfile MusicVolume="100" MicVolume="100" VoiceChat="0" /> <RenderProfile MSAALevel="0" AlphaToCoverage="0" ResolutionX="1280" ResolutionY="720" RefreshRate="60" Fullscreen="1" Borderless="0" VSync="0" TripleBuffering="0"> <QualityProfile PostFX="0" MotionBlur="0" ShadowQuality="0" TerrainQuality="0" VegetationQuality="0" WaterQuality="0" ShaderQuality="0" TextureQuality="0" GeometryQuality="0" AmbientOcclusion="0" /> </RenderProfile> <NetworkProfile EnableUPnP="1" /> <GameProfile Sensitivity="1" InvertY="0" Difficulty="1" /> <ProfileSpecific GamepadLayout="0" /> </GamerProfile>
Use DirectX 9 instead of DirectX 11 for better stability and frame rates on older hardware. Recommended Performance Tools
