Roblox

The AMD Ryzen 7 5700 paired with the NVIDIA GeForce RTX 3080 is a formidable combination for Roblox, delivering frame rates that far exceed the requirements of most displays. The data shows a system that is heavily GPU-limited at lower resolutions but maintains exceptionally high performance across all tested settings, making it an excellent choice for high-refresh-rate gaming in this sandbox title.

Resolution Scaling

The measured FPS data reveals a classic performance curve as resolution increases. At 1080p, the system operates in a CPU-bound territory, with frame rates reaching 484 FPS on Low settings. Dropping to 1440p reduces that figure to 324.5 FPS, a decrease of 33%, while 4K Low brings it down to 180.8 FPS, which is 63% lower than the 1080p result. This scaling pattern indicates that the CPU is the limiting factor at 1080p, as the RTX 3080 has ample headroom to render more frames than the processor can feed.

The gap between resolutions narrows as settings increase, which is a sign of the GPU taking on more work. At High settings, the 1080p score of 384.9 FPS drops to 258.6 FPS at 1440p (a 33% reduction) and then to 145.2 FPS at 4K (a 62% reduction from 1080p). The consistency of these percentage drops across settings suggests that the GPU scaling is predictable, but the absolute numbers remain high enough that even the most demanding 4K Ultra preset holds 119.1 FPS, which is still well above the 60 FPS standard.

The real insight comes from comparing the Low and Ultra presets at each resolution. At 1080p, the difference between Low (484 FPS) and Ultra (311.4 FPS) is 36%, showing that the GPU has enough power to absorb the extra graphical load without collapsing. At 4K, the same comparison shows Low (180.8 FPS) versus Ultra (119.1 FPS), a 34% difference, meaning the GPU is still the primary driver of performance even at the highest pixel count. This indicates that while the CPU holds the system back at 1080p, the RTX 3080 remains the dominant component at 4K, where its 10 GB of GDDR6X memory and 760.3 GB/s bandwidth are fully utilized.

Settings Recommendations

For players targeting the highest refresh rates, the Low preset is the obvious choice, delivering 484 FPS at 1080p and 324.5 FPS at 1440p. These numbers are far beyond what any consumer display can show, so the Low preset is only useful for competitive play where every millisecond counts. However, the data suggests that most users will find the Medium preset to be the sweet spot, as it offers a significant visual upgrade over Low while maintaining 435.3 FPS at 1080p and 293.6 FPS at 1440p. The performance penalty from Low to Medium is 10% at 1080p and 9.5% at 1440p, which is a negligible cost for the improved visuals.

The High preset is the recommended choice for balanced gameplay, as it delivers 384.9 FPS at 1080p and 258.6 FPS at 1440p. These frame rates are still high enough for any 240 Hz or 360 Hz monitor, and the visual fidelity is noticeably better than Medium. The transition from Medium to High costs 11.6% performance at 1080p and 11.9% at 1440p, which is a reasonable trade-off for the graphical enhancement. The Ultra preset is where the system starts to show strain, dropping to 311.4 FPS at 1080p and 208.2 FPS at 1440p, but even these numbers are playable on high-refresh displays.

At 4K, the recommendation shifts. The Ultra preset yields 119.1 FPS, which is above the 60 FPS threshold and suitable for 120 Hz displays, but the High preset at 145.2 FPS offers a 22% improvement with a modest visual difference. For 4K gaming, High is the preferred setting, as it balances the RTX 3080's capabilities with the demands of the resolution. The Low preset at 4K is not recommended, as the visual downgrade is severe for only a 25% gain over High.
