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, frame rates range from 39 to 102 FPS depending on quality settings. At 1440p, frame rates range from 43 to 96 FPS. At 4K, frame rates range from 34 to 75 FPS.
The GeForce RTX 4090 is 843% above the recommended GPU (GeForce GTX 660) for Roblox. The Ryzen 5 3550H is 251% above the recommended CPU (Core 2 Duo).
The GeForce RTX 4090 sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Ryzen 5 3550H still has additional frame-generation headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the GeForce RTX 4090 sets the ceiling at about 38 FPS, while the Ryzen 5 3550H has headroom up to 192 FPS. In this scenario, the GPU limits the CPU potential by 80% (FPS gap: 154 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Ryzen 5 3550H frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 49% | GPU Limits CPU 60% | GPU Limits CPU 67% | GPU Limits CPU 77% |
| 1440p (2K QHD) | GPU Limits CPU 47% | GPU Limits CPU 57% | GPU Limits CPU 63% | GPU Limits CPU 73% |
| 4K (Ultra HD) | GPU Limits CPU 65% | GPU Limits CPU 68% | GPU Limits CPU 72% | GPU Limits CPU 80% |
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.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 251% above and your GPU is 843% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

The Ryzen 5 3550H and GeForce RTX 4090 will struggle to run Roblox at smooth framerates. At 1080p Ultra, you can expect around 39 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
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.
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, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 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 Ryzen 5 3550H 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.
