The Steam Deck (RDNA2 iGPU) is a handheld card with 4GB of VRAM, and Phantom Blade Zero is a demanding, graphically heavy game. Paired with a balanced Intel Core i5-8600K-class CPU it averages about 59 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 | 59 |
| 1440p | 14 | 36 |
| 4K | 8 | 20 |
At 1080p expect around 59 FPS, at 1440p about 36 FPS, and at 4K roughly 20 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.
