Can the Steam Deck (RDNA2 iGPU) run The Callisto Protocol? (2026)

👍 Yes, with tuned settings

~50 FPS at 1080p with optimized settings

The Steam Deck (RDNA2 iGPU) is a handheld card with 4GB of VRAM, and The Callisto Protocol is a demanding, graphically heavy game. Paired with a balanced Intel Core i5-8600K-class CPU it averages about 50 FPS at 1080p with FrameCoach's tuned settings — up from roughly 23 FPS with everything on High.

Resolution	All-High FPS	Optimized FPS
1080p	23	50
1440p	14	30
4K	8	17

💡 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.

At 1080p expect around 50 FPS, at 1440p about 30 FPS, and at 4K roughly 17 FPS with optimized settings. With only 4GB of VRAM, keep textures a notch below max at higher resolutions to avoid stutter. The single biggest improvement is FSR upscaling — set it to Quality.
