Roblox

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, delivering an average of 193.5 FPS. This is far above the 60 FPS threshold, leaving substantial headroom for frame drops or background tasks. Low settings reach 295.6 FPS, Medium hits 266.1 FPS, and High records 237.3 FPS, but Ultra remains the optimal choice for maximum visual quality without sacrificing fluidity.

At 2560x1440, Ultra is again the best setting, averaging 130 FPS. The gap to the next preset down, High at 157.9 FPS, is noticeable but not decisive; Ultra still clears the 60 FPS requirement by more than double. Low settings produce 195.8 FPS and Medium reaches 179.8 FPS, but none of these lower presets are necessary to maintain playability at this resolution.

At 3840x2160, the most demanding preset that stays at or above 60 FPS is also Ultra, with an average of 71.4 FPS. This is the tightest margin of the three resolutions: Ultra remains above the threshold, but only by about 11.4 FPS. High averages 91.4 FPS, Medium 102.4 FPS, and Low 110.3 FPS, giving the user several fallback options if they want a larger safety cushion. The data shows that this combination can run Roblox at Ultra settings across all tested resolutions, with the 4K Ultra result being the closest call.

CPU and GPU Roles

The recorded data shows a consistent pattern: as resolution increases, average FPS decreases across every preset. At 1080p Ultra, the combo produces 193.5 FPS. Moving to 1440p Ultra drops that to 130 FPS, a reduction of about 32.8%. At 4K Ultra, the FPS falls to 71.4, another 45.1% drop from 1440p. This scaling curve indicates that the GPU is becoming the limiting factor at higher resolutions.

The delta between Low and Ultra settings grows as resolution increases. At 1080p, Low averages 295.6 FPS versus Ultra at 193.5 FPS, a spread of 102.1 FPS. At 1440p, Low and Ultra differ by 65.8 FPS (195.8 versus 130.0). At 4K, the spread narrows to 38.9 FPS (110.3 versus 71.4). This pattern is consistent with the GPU load rising faster than the CPU load as resolution climbs, turning the Arc B580 into the primary limiter.

At 1080p, the i5-11400F still has enough headroom to push very high frame rates: the lowest preset (Low) exceeds 295 FPS, far beyond what the GPU must deliver. The small FPS gap between Medium and High at 1080p (266.1 versus 237.3, a 28.8 FPS difference) suggests that the CPU is not the bottleneck at these settings. The data indicates that at 1080p, the CPU is idling relative to the GPU, but the GPU is not saturated either.

At 4K, the picture changes. The gap between Low and Ultra is only 38.9 FPS, and even Low cannot reach 120 FPS. This shows that the GPU is the dominant factor at 4K, with the CPU contributing less to the total frame time. The Intel Core i5-11400F, with its 6 cores and 12 threads, is sufficient to feed the GPU at all resolutions, but the data does not show meaningful CPU utilization differences across presets. The measured FPS at 4K Ultra (71.4) is only 62% of the 1080p Ultra figure, which aligns with the GPU's compute load scaling roughly with pixel count.

Measured FPS Breakdown

1920x1080:

• Low: average 295.6 FPS, no min or max recorded
• Medium: average 266.1 FPS
• High: average 237.3 FPS
• Ultra: average 193.5 FPS

2560x1440:

• Low: average 195.8 FPS
• Medium: average 179.8 FPS
• High: average 157.9 FPS
• Ultra: average 130.0 FPS

3840x2160:

• Low: average 110.3 FPS
• Medium: average 102.4 FPS
• High: average 91.4 FPS
• Ultra: average 71.4 FPS

The recorded data does not include minimum or maximum frame times for any resolution or preset, so the analysis relies solely on average FPS. The averages show a consistent monotonic decrease as settings rise and resolution increases. The largest single step is from Low to Medium at 4K: 110.3 to 102.4, a drop of 7.9 FPS. The smallest absolute step is from Medium to High at 4K: 102.4 to 91.4, a drop of 11.0 FPS. At 1440p, the step from High to Ultra is 27.9 FPS, the largest relative setting penalty in the dataset. At 1080p, the step from High to Ultra is 43.8 FPS, which is the largest absolute drop between adjacent settings.

Comparing across resolutions, the 1080p Low result (295.6 FPS) is more than double the 4K Ultra result (71.4 FPS). The 1440p Ultra result (130.0 FPS) is roughly 67% faster than 4K Ultra. These numbers confirm that the B580's bandwidth and compute resources scale with resolution in a predictable way.

FAQ

Q: Can this PC run Roblox at 4K Ultra?

A: Yes. The measured average FPS at 3840x2160 Ultra is 71.4, which is above the 60 FPS playable threshold. The verdictByResolution lists Ultra as the best playable setting for that resolution.

Q: What is the best preset for 1440p if I want maximum visual quality?

A: Ultra. At 2560x1440 Ultra, the average is 130.0 FPS, which is well above 60 FPS. The data shows all four presets are playable at this resolution, but Ultra gives the highest visual fidelity without dropping below 60.

Q: How much FPS do I lose by switching from Low to Ultra at 1080p?

A: The average FPS drops from 295.6 on Low to 193.5 on Ultra, a difference of 102.1 FPS. Even the Ultra preset still runs at over triple the playable threshold.

Q: Is the CPU or GPU the limiting factor at 4K?

A: The data indicates the GPU is the primary constraint. At 4K, the FPS gap between Low and Ultra is only 38.9 FPS, whereas at 1080p the gap is 102.1 FPS. This shrinking spread at higher resolutions points to the GPU becoming the bottleneck as resolution climbs.

Q: Should I use Medium or High at 1440p?

A: Both are playable, but High produces 157.9 FPS versus Medium's 179.8 FPS. The 21.9 FPS difference is noticeable on high refresh rate monitors. If visual quality is preferred, High is fine; if the user wants more headroom, Medium is better.

Q: At what resolution does this combo exceed 200 FPS?

A: The only resolution where any preset exceeds 200 FPS is 1080p Low, which averages 295.6 FPS. No 1440p or 4K preset reaches 200 FPS.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-11400F are based on the database's average benchmark scores. The AMD EPYC 7H12 scores 17120, which is 0.3% higher than the i5-11400F's 17177. The Intel Core i5-12450H scores 17239, 0.4% higher. The AMD Ryzen 3 PRO 8300G scores 17278, 0.6% higher. These three processors would deliver nearly identical CPU-bound behavior in Roblox, with differences under 1 percent.

On the GPU side, the Intel Arc B580 has an average benchmark score of 23021. Its nearest rivals are the AMD Radeon RX 580 2048SP at 23061 (0.2% higher), the NVIDIA GeForce RTX 2080 at 22895 (0.6% lower), the NVIDIA GeForce RTX 3080 at 23172 (0.7% higher), and the NVIDIA P106-100 at 23249 (1.0% higher). The RTX 2060 and RTX 2080 are within 1 percent of the Arc B580, so users with those cards would experience nearly the same FPS in Roblox. The RTX 3080 is only 0.7% faster, which is within measurement noise. Note that the P106-100 is a mining card, not a gaming product, but the database includes it as a benchmark comparison.

The practical implication is that Roblox is not sensitive to the small differences among these processors and GPUs. Any of these rivals would produce average FPS within a few frames of the i5-11400F + Arc B580 combination at the same settings. The CPU percentile of 71 and GPU percentile of 68 indicate this combo sits in the upper third of all tested hardware.

How This Combo Ranks

The database ranks this combination as 2820 out of 3711 tested combos for Roblox. That places it in the 24th percentile from the top, meaning about 76% of tested combinations are faster in this game. The rank is determined by the average FPS across all settings and resolutions, but the measured figures show that the combo is well above 60 FPS at all settings and resolutions.

The rank of 2820 may seem low, given the high FPS numbers. However, Roblox is a lightweight sandbox title that tends to run at very high frame rates on many systems. The database includes many combinations with more powerful CPUs and GPUs, such as the RTX 3080 and EPYC 7H12, which score higher. The rank data shows that this combo is not a top performer in absolute terms, but it remains fully playable in every scenario.

The 3711 total combos span a wide range, from low-end office PCs to multi-GPU workstations. The i5-11400F with Arc B580 is in the middle of the pack, not a flagship configuration. For Roblox specifically, the high FPS margins (70+ FPS at 4K Ultra) indicate that the rank reflects absolute performance rather than playability.

The Verdict

The data clearly shows that the Intel Core i5-11400F + Intel Arc B580 can run Roblox at 60 FPS or higher at every resolution and setting combination tested. The verdictByResolution confirms that all four settings (Low, Medium, High, Ultra) are playable at 1080p, 1440p, and 4K.

At 1920x1080, the best playable setting is Ultra with 193.5 FPS average. At 2560x1440, the best is Ultra with 130.0 FPS average. At 3840x2160, Ultra is still the best, averaging 71.4 FPS. The lowest recorded average in the entire dataset is 71.4 FPS, which is 11.4 FPS above the 60 FPS threshold. This gives the user a comfortable margin at 4K Ultra.

The only consideration is that 4K Ultra operates with a smaller headroom relative to 60 FPS. If the user prefers a larger safety margin, they can drop to High at 4K, which provides 91.4 FPS, a 31.4 FPS buffer. But the data shows no playability concern: every preset at every resolution exceeds the threshold.

In short, this PC is fully capable of running Roblox with maximum visual settings at any resolution up to 4K. The CPU and GPU both contribute to the high frame rates, with the GPU becoming more important at 4K. Users with a 60 Hz monitor can enable Ultra at 4K without issue; those with 144 Hz monitors should stick to 1080p or 1440p Ultra, which provide 193.5 and 130.0 FPS respectively.
