🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.
Recommended settings
Upscaling — FSRBalanced+55% FPS
The Callisto Protocol (Unreal Engine 4) supports DLSS and FSR. Enable it first - the game is demanding and stutter-prone.
Ray Tracing (Reflections / Shadows)Offsaves FPS
Ray-traced reflections and shadows. Heavy and known to worsen the game's stutter - keep Off for smoother frames.
Shadow QualityLow+10% FPS
Shadow resolution and range. High is the value pick.
Screen Space ReflectionsOff+7% FPS
Reflections on the prison's wet metal surfaces. Medium is plenty without ray tracing.
Volumetric QualityLow+6% FPS
Fog and light shafts - core to the grim atmosphere but a real cost. Medium is a clean trade.
Effects QualityLow+6% FPS
Gore and combat effects. Lowering smooths the brutal melee fights.
Ambient OcclusionOff+5% FPS
Soft contact shadows for depth. Medium is a cheap, good-looking option.
Anti-AliasingOff+4% FPS
Edge smoothing. Medium keeps the image clean cheaply.
Texture QualityUltra-1% FPS
Surface sharpness - cheap if it fits your VRAM.
