Roblox

Roblox with an Intel Core i9-14900K and NVIDIA GeForce RTX 5090 D produces an extraordinary performance profile, placing the combination at the very top of the tested database. The data indicates a system capable of delivering extremely high frame rates across all resolution tiers, with the bottleneck shifting in predictable ways as graphical load increases. This analysis breaks down the measured results, contextualizes them against other tested combinations, and provides actionable settings guidance based solely on the provided figures.

Resolution Scaling

The measured FPS data reveals a clear scaling pattern as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average frame rate drops from 625 FPS at 1080p to 417 FPS at 1440p, and further to 236 FPS at 4K. This represents a 33% reduction moving from 1080p to 1440p, and a 43% reduction from 1440p to 4K. The scaling is steep, indicating that the GPU is becoming increasingly burdened by the pixel count, though the absolute numbers remain exceptionally high.

The Low preset shows a similar trajectory, with 776 FPS at 1080p, 518 FPS at 1440p, and 293 FPS at 4K. The percentage drops are consistent with the High preset, suggesting that the resolution scaling factor is relatively uniform across settings. However, the gap between Low and High settings narrows at higher resolutions. At 1080p, Low is 24% faster than High (776 vs 625 FPS), but at 4K, Low is only 24% faster as well (293 vs 236 FPS), maintaining a proportional difference.

The Medium preset provides the only complete min/max data, showing 706 FPS average at 1080p with a minimum of 600 FPS and maximum of 812 FPS. At 1440p, the average drops to 471 FPS with a range of 401-542 FPS, and at 4K, it averages 267 FPS with a range of 227-307 FPS. The consistency of these ranges indicates stable frame pacing, with the minimums staying well above 200 FPS even at 4K.

The Ultra preset yields the lowest average frame rates: 507 FPS at 1080p, 338 FPS at 1440p, and 191 FPS at 4K. The 4K Ultra figure is the only measured average below 200 FPS, suggesting that this is the most demanding configuration tested. The scaling from 1080p to 4K at Ultra represents a 62% reduction in average FPS, which is the largest relative drop across all presets, highlighting the compounding effect of higher settings and resolution.

The data suggests that at 1080p, the CPU is likely the limiting component, as the frame rates exceed 500 FPS even at Ultra, which is far beyond what most displays can show. At 4K, the GPU becomes the primary constraint, with the RTX 5090 D's capabilities being stretched by the higher pixel count. The transition point appears to be around 1440p, where the balance between CPU and GPU load is most equitable.
