The AMD RX 580 (4GB) is a entry-level card with 4GB of VRAM, and Roblox is a lightweight, high-frame-rate esports title. Paired with a balanced Intel Core i5-8600K-class CPU it averages about 90 FPS at 1080p with FrameCoach's tuned settings — up from roughly 90 FPS with everything on High.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 90 | 90 |
| 1440p | 54 | 60 |
| 4K | 31 | 34 |
At 1080p expect around 90 FPS, at 1440p about 60 FPS, and at 4K roughly 34 FPS with optimized settings. Roblox doesn't use upscaling, so the gains come from trimming the heaviest settings.
