Roblox

Roblox is not typically the first title that comes to mind when discussing high-end PC hardware, but the data for the Intel Core Ultra 7 265K and AMD Radeon RX 7700 combination reveals a system with massive headroom. The measured frame rates are exceptionally high, indicating that this pairing is far more capable than the game demands, with the CPU and GPU both showing significant performance reserves.

Resolution Scaling

The performance drop from 1080p to 4K is the clearest indicator of how this system scales under increasing graphical load. At Low settings, the average frame rate falls from 386 FPS at 1920x1080 to 146 FPS at 3840x2160. That is a 62% reduction in frame rate when moving from Full HD to 4K. This steep decline points directly to the GPU becoming the primary limiting factor as pixel count multiplies. The RX 7700 is working much harder to fill those 4K pixels, and despite the significant drop, the result is still a very playable 146 FPS.

The scaling pattern is consistent across the other presets. At High settings, the average drops from 311 FPS at 1080p to 207 FPS at 1440p, and finally to 117 FPS at 4K. The step from 1080p to 1440p represents a 33% decrease in frame rate, while the step from 1440p to 4K represents a 43% decrease. This shows that the GPU load is compounding as resolution increases, which is expected, but the absolute numbers remain high enough that the game never approaches a performance wall.

The Medium preset shows a similar trend, with averages of 352 FPS at 1080p, 235 FPS at 1440p, and 133 FPS at 4K. The most demanding Ultra preset starts at 252 FPS at 1080p, drops to 168 FPS at 1440p, and bottoms out at 95 FPS at 4K. The difference between the Low and Ultra presets at 4K is 51 FPS, which demonstrates that the visual settings have a substantial impact on the GPU workload. The data suggests that at 1080p and 1440p, the CPU is likely providing a high ceiling, but at 4K, the GPU is the definitive bottleneck, as evidenced by the larger relative frame rate drops at that resolution.

Settings Recommendations

The measured data paints a clear picture of a system that excels at high refresh rates. For users with a 1080p or 1440p monitor with a high refresh rate (144Hz or higher), the Ultra preset is the best choice. The average frame rate of 252 FPS at 1080p and 168 FPS at 1440p is more than sufficient to take full advantage of such displays, and the visual quality improvements from the Ultra preset are essentially free in terms of playability.

For 4K gaming, the choice is more nuanced. The Ultra preset, with an average of 95 FPS, is perfectly playable and offers the best visual experience. The High preset, averaging 117 FPS, provides a meaningful 22 FPS increase, which might be preferable for users who prioritize smoother motion over the highest visual fidelity. The jump from High to Ultra at 4K costs about 19% of the average frame rate. Given the data, the High preset at 4K appears to be the sweet spot for balancing visual quality with a higher performance buffer, while Ultra remains viable for those who want the absolute best image quality without dropping below the 90 FPS mark.

The Medium preset offers a balanced middle ground, with an average of 352 FPS at 1080p, 235 FPS at 1440p, and 133 FPS at 4K. It provides a significant frame rate advantage over Ultra, but the visual difference may not be worth the performance loss for most users, especially since the High preset is available as an intermediate step. The Low preset is only recommended for competitive play where maximum frame rates are paramount, but the data shows that even the High preset at 1080p (311 FPS) and 1440p (207 FPS) provides ample performance headroom for most competitive scenarios.
