On a NVIDIA RTX 5090 (paired with a balanced Intel Core i9-14900K-class CPU), Mafia II: Definitive Edition runs at roughly 245 FPS at 4K with our optimized settings — up from about 245FPS with everything maxed. Here's the configuration and what each setting costs.
The NVIDIA RTX 5090 is a flagship 4K-class graphics card with 32GB of VRAM, and Mafia II: Definitive Edition is a relatively light game to run. Paired with the Intel Core i9-14900K, it flies at 4K — about 245 FPSwith FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.
Across resolutions you can expect around 263 FPS at 1080p and 263 FPS at 1440p, dropping to roughly 245 FPS at 4K. Its 32GB of VRAM is plenty for Mafia II: Definitive Edition, so textures can stay maxed. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 263 | 263 |
| 1440p | 263 | 263 |
| 4K | 245 | 245 |
