Best The Callisto Protocol settings for the NVIDIA RTX 4080 (2026)

On a NVIDIA RTX 4080 (paired with a balanced Intel Core i9-14900K-class CPU), The Callisto Protocol runs at roughly 80 FPS at 4K with our optimized settings — up from about 60FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA RTX 4080 is a flagship 4K-class graphics card with 16GB of VRAM, and The Callisto Protocol is a demanding, graphically heavy game. Paired with the Intel Core i9-14900K, it runs well at 4K — about 80 FPS with FrameCoach's optimized settings, a clear jump from roughly 60 FPS with everything on High.

Across resolutions you can expect around 174 FPS at 1080p and 105 FPS at 1440p, dropping to roughly 80 FPS at 4K. The Callisto Protocol supports ray tracing and the NVIDIA RTX 4080 can technically run it, but it's the single most expensive option here — we keep it off to hit a smooth frame rate and suggest turning it on only if you have frames to spare. Its 16GB of VRAM is plenty for The Callisto Protocol, so textures can stay maxed. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.

💡 The Callisto Protocol: Prone to shader-compilation stutter - ray tracing makes it worse.
🚀 Biggest free win: enable DLSS (Quality) — about +35% FPS for a small sharpness trade.
Recommended settings
Upscaling — DLSSQuality+35% 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.
Texture QualityUltra-1% FPS
Surface sharpness - cheap if it fits your VRAM.
Shadow QualityHighbaseline
Shadow resolution and range. High is the value pick.
Screen Space ReflectionsMediumbaseline
Reflections on the prison's wet metal surfaces. Medium is plenty without ray tracing.
VolumetricsMediumbaseline
Fog and light shafts - core to the grim atmosphere but a real cost. Medium is a clean trade.
ParticlesHighbaseline
Gore and combat particle effects. Lowering smooths the brutal melee fights.
Ambient OcclusionMediumbaseline
Soft contact shadows for depth. Medium is a cheap, good-looking option.
Anti-AliasingHighbaseline
Edge smoothing. Medium keeps the image clean cheaply.
