The Steam Deck (RDNA2 iGPU) is a handheld card with 4GB of VRAM, and Warhammer 40K: Space Marine 2 is a demanding, graphically heavy game. Paired with a balanced Intel Core i5-8600K-class CPU it averages about 56 FPS at 1080p with FrameCoach's tuned settings — up from roughly 26 FPS with everything on High.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 26 | 56 |
| 1440p | 15 | 34 |
| 4K | 9 | 19 |
At 1080p expect around 56 FPS, at 1440p about 34 FPS, and at 4K roughly 19 FPS with optimized settings. The single biggest improvement is FSR upscaling — set it to Quality.
