Scales from mobile devices to high-end PCs. The engine is lightweight and typically capped at 60 FPS. It requires a stable internet connection for asset streaming and a DX10 compatible GPU.
This game has a built-in FPS cap of 60 FPS
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 270 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 266 FPS. At 4K, all settings exceed 185 FPS.
The GeForce RTX 4090 is 843% above the recommended GPU (GeForce GTX 660) for Roblox. The Xeon Gold 6240 is 1037% above the recommended CPU (Core 2 Duo).
The Xeon Gold 6240 determines the performance ceiling at 1080p (low/medium), 1440p medium, all 4k settings, while the GPU has headroom. The system is well balanced at 1080p (high/ultra), 1440p (low/high/ultra).
At 4k medium, the Xeon Gold 6240 sets the ceiling at about 212 FPS, while the GeForce RTX 4090 could reach 254 FPS. In this scenario, the CPU limits the GPU potential by 17% (FPS gap: 42 FPS). Overall distribution: CPU limits 7/12 cells, GPU limits 0/12, balanced 5/12.
Your Xeon Gold 6240 is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 6% | CPU Limits GPU 16% | Balanced | Balanced |
| 1440p (2K QHD) | Balanced | CPU Limits GPU 9% | Balanced | Balanced |
| 4K (Ultra HD) | CPU Limits GPU 7% | CPU Limits GPU 17% | CPU Limits GPU 15% | CPU Limits GPU 16% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Yes, the Xeon Gold 6240 paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 185 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 1037% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Roblox, upgrading the CPU would have the biggest impact on performance. The Xeon Gold 6240 is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1440p medium, 4k low, 4k medium, 4k high, 4k ultra.
Roblox does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Roblox requires at minimum a Celeron D (CPU) and GeForce 6600 (GPU) with 1 GB RAM and 20 MB storage. For the recommended experience, you need a Core 2 Duo and GeForce GTX 660 with 4 GB RAM. Your Xeon Gold 6240 and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Roblox FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
