Best The Callisto Protocol settings for the NVIDIA GTX 650 (1GB) (2026)

On a NVIDIA GTX 650 (1GB) (paired with a balanced Intel Core i5-8600K-class CPU), The Callisto Protocol runs at roughly 13 FPS at 1080p with our optimized settings — up from about 6FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA GTX 650 (1GB) is a entry-level graphics card with 1GB of VRAM, and The Callisto Protocol is a demanding, graphically heavy game. Paired with the Intel Core i5-8600K, it is a real challenge at 1080p — about 13 FPS with FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.

Across resolutions you can expect around 13 FPS at 1080p and 8 FPS at 1440p, dropping to roughly 5 FPS at 4K. The Callisto Protocol offers ray tracing, but the NVIDIA GTX 650 (1GB) isn't built for it, so we leave it off. With only 1GB of VRAM, keep textures a notch below max in The Callisto Protocol at higher resolutions to avoid stutter. The biggest free win is FSR 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 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.
VolumetricsLow+6% FPS
Fog and light shafts - core to the grim atmosphere but a real cost. Medium is a clean trade.
ParticlesLow+6% FPS
Gore and combat particle 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.
