The Steam Deck (RDNA2 iGPU) is a handheld card with 4GB of VRAM, and Metal Gear Solid Δ: Snake Eater is a one of the most punishing games to run on PC. Paired with a balanced Intel Core i5-8600K-class CPU it averages about 54 FPS at 1080p with FrameCoach's tuned settings — up from roughly 21 FPS with everything on High.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 21 | 54 |
| 1440p | 12 | 33 |
| 4K | 7 | 19 |
At 1080p expect around 54 FPS, at 1440p about 33 FPS, and at 4K roughly 19 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.
