Roblox

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which delivers an average of 171 FPS. The margin is substantial, leaving more than 110 FPS of headroom above the playability threshold.

At 2560x1440, the Ultra preset again clears the 60 FPS bar comfortably, with an average of 114 FPS. This is a typical result for a sandbox title where the rendering load scales moderately with resolution, and the recorded data confirms that even the highest settings remain well within playable territory.

At 3840x2160, the Ultra preset still holds an average of 65 FPS, which is above the 60 FPS threshold but with far less headroom than at lower resolutions. The data shows that 4K Ultra is the most demanding configuration tested, and the margin above the playability threshold is only 5 FPS. For users who prefer a larger safety buffer at 4K, dropping to High yields 80 FPS average, while Medium produces 90 FPS average and Low reaches 99 FPS average. However, based strictly on the requirement of maintaining at least 60 FPS, Ultra remains the best setting at every resolution tested.

CPU and GPU Roles

The recorded FPS scaling across resolutions reveals how the balance between CPU and GPU shifts as pixel count increases. At 1920x1080, the differences between presets are relatively large: Low averages 262 FPS, Medium 239 FPS, High 211 FPS, and Ultra 171 FPS. This spread of 91 FPS between Low and Ultra indicates that the GPU is still the primary limiter, but the CPU is capable of feeding very high frame rates without becoming a bottleneck.

Moving to 2560x1440, the same preset ladder shows Low at 175 FPS, Medium at 159 FPS, High at 141 FPS, and Ultra at 114 FPS. The absolute FPS values drop by roughly 33 to 39 percent compared to 1080p for each preset, which is consistent with the increased pixel count requiring more GPU work. The CPU load does not change meaningfully with resolution, so the scaling here is almost entirely GPU-driven.

At 3840x2160, the preset ladder compresses further: Low averages 99 FPS, Medium 90 FPS, High 80 FPS, and Ultra 65 FPS. The gap between Low and Ultra shrinks to 34 FPS, compared to 91 FPS at 1080p. This compression indicates that at 4K, the GPU becomes the dominant constraint, and raising settings has a smaller relative impact because the pixel fill rate is already the limiting factor.

Across all three resolutions, the CPU appears to be sufficient to keep frame rates high. The fact that 1080p Low reaches 262 FPS and 1080p Ultra still reaches 171 FPS suggests that the AMD Ryzen 5 3600 paired with the Intel Arc B570 does not create a severe CPU bottleneck, even at lower resolutions where CPU overhead is typically more visible. The data shows that the GPU is the more influential component for this game at every resolution tested, with the CPU providing enough throughput to support the high frame rates observed.

Measured FPS Breakdown

At 1920x1080, the full set of measurements is as follows. Low settings produce an average of 262 FPS. Medium settings produce an average of 239 FPS, with a minimum of 203 FPS and a maximum of 275 FPS. High settings produce an average of 211 FPS. Ultra settings produce an average of 171 FPS. Every preset at this resolution stays far above the 60 FPS playability threshold, with the lowest recorded minimum (203 FPS at Medium) still more than three times the threshold.

At 2560x1440, the measurements are: Low at 175 FPS average, Medium at 159 FPS average with a minimum of 135 FPS and a maximum of 183 FPS, High at 141 FPS average, and Ultra at 114 FPS average. The minimum at Medium, 135 FPS, remains well above the playability threshold. The step from High to Ultra costs 27 FPS, while the step from Low to Medium costs 16 FPS, showing that the more demanding settings impose a larger performance penalty at this resolution.

At 3840x2160, the measurements are: Low at 99 FPS average, Medium at 90 FPS average with a minimum of 77 FPS and a maximum of 104 FPS, High at 80 FPS average, and Ultra at 65 FPS average. The minimum recorded at 4K Medium is 77 FPS, which is still above the 60 FPS threshold. The Ultra preset, with an average of 65 FPS, is the only configuration tested that approaches the threshold, but it does not fall below it in the recorded average.

The Medium preset at each resolution is the only one with complete min and max data. At 1080p, the min-to-max range is 72 FPS. At 1440p, the range is 48 FPS. At 4K, the range is 27 FPS. This narrowing range at higher resolutions further supports the interpretation that GPU load dominates at 4K, reducing the variability introduced by scene complexity or CPU-side frame pacing.

FAQ

Q: Can this system run Roblox at 4K Ultra settings?

A: Yes. The recorded data shows an average of 65 FPS at 3840x2160 with Ultra settings, which is above the 60 FPS playability threshold. The margin is small, but the configuration clears the bar.

Q: What is the best settings preset for 1440p?

A: Ultra is the best preset at 2560x1440, with an average of 114 FPS. All four presets at this resolution exceed 60 FPS, so the choice comes down to visual quality versus frame rate preference.

Q: How much performance is lost when moving from 1080p to 4K?

A: At Ultra settings, the average drops from 171 FPS at 1920x1080 to 114 FPS at 2560x1440, then to 65 FPS at 3840x2160. The largest relative drop occurs between 1440p and 4K, where the average falls by 49 FPS.

Q: Is the minimum FPS ever below 60?

A: The only preset with recorded minimum data is Medium. At 1920x1080 the minimum is 203 FPS, at 2560x1440 it is 135 FPS, and at 3840x2160 it is 77 FPS. All recorded minimums are above 60 FPS.

Q: Which component is the limiting factor at 1080p?

A: The data indicates the GPU is still the primary limiter at 1080p, as shown by the 91 FPS spread between Low and Ultra presets. The CPU is capable of supporting frame rates above 260 FPS at Low settings, so it is not the bottleneck.

Q: Does the system meet the playability threshold at every resolution?

A: Yes. The verdict data lists High, Low, Medium, and Ultra as playable settings at 3840x2160, 2560x1440, and 1920x1080. The lowest average among all tested configurations is 65 FPS at 4K Ultra.

How This Combo Ranks

The combination of the AMD Ryzen 5 3600 and Intel Arc B570 ranks 2972 out of 3711 tested combos in Roblox. This places the system in the lower portion of the database, around the 20th percentile of all tested configurations. The rank reflects the fact that Roblox is not an exceptionally demanding title, and many higher-end combinations naturally achieve higher frame rates, but the absolute performance of this combo is still sufficient for smooth play at all tested resolutions.

The CPU alone sits at the 71st percentile among all CPUs in the database, while the GPU sits at the 65th percentile among all GPUs. The combo rank being lower than either individual component percentile suggests that the pairing, while balanced, does not push into the upper echelon of overall system performance for this specific game. The measured frame rates, however, show that this lower ranking does not translate into an unplayable experience. A rank near the bottom quarter of the database simply means many other systems produce higher averages, not that this one struggles to maintain 60 FPS.

The Verdict

This PC can run Roblox at every resolution and setting combination recorded in the database. At 3840x2160, the best settings preset is Ultra with an average of 65 FPS, which clears the 60 FPS threshold. At 2560x1440, Ultra averages 114 FPS. At 1920x1080, Ultra averages 171 FPS. All four presets at each resolution are listed as playable, meaning there is no configuration in the measured data that falls below the playability threshold.

The strongest performance is at 1080p, where even the most demanding preset leaves enormous headroom. The 1440p results are equally comfortable, with the Ultra preset still more than 50 FPS above the threshold. At 4K, the system remains playable at Ultra, but the margin narrows considerably. Users targeting a strict 60 FPS lock at 4K may prefer High settings for a buffer of 80 FPS average, but the data confirms that Ultra is technically playable.

Similar Performance Alternatives

The nearest rivals for the AMD Ryzen 5 3600, based on average benchmark score, are the Intel Core i7-1260P with a score of 17007 and a delta of 0.2 percent, the Intel Core i5-11400 with a score of 17067 and a delta of -0.2 percent, the AMD EPYC 7573X with a score of 17070 and a delta of -0.2 percent, and the AMD EPYC 7742 with a score of 16998 and a delta of 0.2 percent. Any of these CPUs would deliver effectively identical CPU-side performance in Roblox, since the delta between them is within a fraction of a percent.

The nearest rivals for the Intel Arc B570 are the NVIDIA GeForce RTX 3070 Mobile with an average score of 20534 and a delta of 0.1 percent, the Intel Arc A750 with a score of 20582 and a delta of -0.1 percent, the NVIDIA Quadro M4000M with a score of 20480 and a delta of 0.4 percent, and the AMD Radeon R9 M390X with a score of 20662 and a delta of -0.5 percent. Systems built with any of these GPUs, paired with a CPU of similar standing, would produce frame rates very close to those recorded for this combo. The Intel Arc A750 is the closest match in terms of architectural lineage and performance, while the RTX 3070 Mobile represents a comparable mobile option.

For users considering hardware changes, swapping either component for one of these near-identical rivals would not meaningfully alter the Roblox experience. The measured frame rates would remain within a small margin, and the playability verdict at each resolution would stay the same. The data shows that this performance tier is well established, with multiple CPUs and GPUs clustering around the same benchmark scores.
