The Steam Deck (RDNA2 iGPU) is a handheld card with 4GB of VRAM, and Project Zomboid is a relatively light game to run. Paired with a balanced Intel Core i5-8600K-class CPU it averages about 77 FPS at 1080p with FrameCoach's tuned settings — up from roughly 77 FPS with everything on High.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 77 | 77 |
| 1440p | 46 | 62 |
| 4K | 26 | 55 |
At 1080p expect around 77 FPS, at 1440p about 62 FPS, and at 4K roughly 55 FPS with optimized settings. Project Zomboid doesn't use upscaling, so the gains come from trimming the heaviest settings.
