The Steam Deck (RDNA2 iGPU) is a handheld card with 4GB of VRAM, and Mafia II: Definitive Edition is a relatively light game to run. Paired with a balanced Intel Core i5-8600K-class CPU it averages about 60 FPS at 1080p with FrameCoach's tuned settings — up from roughly 60 FPS with everything on High.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 60 | 60 |
| 1440p | 36 | 63 |
| 4K | 20 | 44 |
At 1080p expect around 60 FPS, at 1440p about 63 FPS, and at 4K roughly 44 FPS with optimized settings. Mafia II: Definitive Edition doesn't use upscaling, so the gains come from trimming the heaviest settings.
