The NVIDIA RTX 4090 is a flagship 4K-class card with 24GB of VRAM, and Fortnite is a demanding, graphically heavy game. Paired with a balanced Intel Core i9-14900K-class CPU it averages about 89 FPS at 4K with FrameCoach's tuned settings — up from roughly 90 FPS with everything on High.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 263 | 262 |
| 1440p | 159 | 157 |
| 4K | 90 | 89 |
At 1080p expect around 262 FPS, at 1440p about 157 FPS, and at 4K roughly 89 FPS with optimized settings. Its 24GB of VRAM is plenty for Fortnite. Fortnite doesn't use upscaling, so the gains come from trimming the heaviest settings.
