| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 205 | 205 |
| 1440p | 181 | 181 |
| 4K | 103 | 103 |
At 1080p expect around 205 FPS, at 1440p about 181 FPS, and at 4K roughly 103 FPS with optimized settings. Its 24GB of VRAM is plenty for Arma 3. Arma 3 doesn't use upscaling, so the gains come from trimming the heaviest settings.
