Resolution Scaling

The measured frame rates for Roblox with the Intel Core i5-12400F and AMD Radeon RX 7600 XT show a clear pattern of performance scaling as resolution increases. At 1920x1080 with High settings, the combination delivers 254.9 FPS, which drops to 169.4 FPS at 2560x1440 and further to 97.3 FPS at 3840x2160. This represents a 33.5% reduction from 1080p to 1440p, and a 61.8% reduction from 1080p to 4K. The scaling is consistent across all settings presets, indicating that the frame rate drop is primarily driven by the GPU's rendering workload rather than any CPU limitation.

Examining the Low preset reveals a different story. At 1080p Low, the system produces 322.6 FPS, while 1440p Low yields 215.4 FPS, and 4K Low produces 120.9 FPS. The percentage drops are 33.2% and 62.5% respectively, nearly identical to the High preset scaling. This similarity suggests that the resolution scaling behavior is uniform regardless of graphical complexity, which is characteristic of a GPU-bound scenario at higher resolutions. The fact that even at Low settings the frame rate falls substantially from 1080p to 4K indicates the GPU is the limiting component once pixel count increases significantly.

Ultra settings show the most dramatic scaling. At 1080p Ultra, the system achieves 208.8 FPS, dropping to 137 FPS at 1440p and 76.4 FPS at 4K. The 4K result is the lowest measured across the entire dataset, representing a 63.4% reduction from 1080p Ultra. This steeper decline at Ultra settings suggests that the additional graphical features enabled at this preset amplify the GPU's workload disproportionately at higher resolutions. The gap between Low and Ultra at 4K is 44.5 FPS, whereas at 1080p the gap is 113.8 FPS, demonstrating that resolution scaling compresses the performance differences between settings.
