At 4k low, the GeForce RTX 4090 sets the ceiling at about 273 FPS, while the Core i9-11900KF has headroom up to 356 FPS. In this scenario, the GPU limits the CPU potential by 23% (FPS gap: 83 FPS). Overall distribution: GPU limits 8/12 cells, CPU limits 0/12, balanced 4/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Core i9-11900KF frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 8% | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | GPU Limits CPU 15% | Balanced | GPU Limits CPU 10% | GPU Limits CPU 7% |
| 4K (Ultra HD) | GPU Limits CPU 23% | GPU Limits CPU 16% | GPU Limits CPU 19% | GPU Limits CPU 13% |
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.

The Core i9-11900KF + GeForce RTX 4090 pairing runs this title with CPU utilization between 12% and 46% and GPU utilization between 13% and 55%. Core i9-11900KF keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 25% at 1080p to 39% at 4K, while CPU averages move from 28% to 29%.
Neither component is close to saturation: CPU tops out at 46% and GPU at 55%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput.
At 1080p, averages sit around CPU 28% and GPU 25%. At 1440p, that shifts to CPU 29% and GPU 34%, and at 4K it reaches CPU 29% and GPU 39%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) High is the most balanced preset based on this dataset. It runs around CPU 30% (14-46%) and GPU 40% (24-55%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i9-11900KF remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core i9-11900KF and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Core i9-11900KF paired with the GeForce RTX 4090 can run Roblox smoothly up to 4k achieving around 248 FPS at Ultra quality. Your GPU is 843% above the recommended specs, and your CPU is 1022% above the recommended requirements.
This CPU + GPU combo costs approximately $1998 ($349 CPU (Rank #279 Value) + $1649 GPU (Rank #77 Value)). Your GeForce RTX 4090 provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end card with a significantly better value rating.
Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your Roblox performance right now. GPU fully utilized at: 1080p low, 1440p low, 1440p high, 1440p ultra, 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 Core i9-11900KF 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.
