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 34 to 68 FPS depending on quality settings. At 1440p, frame rates range from 25 to 51 FPS. At 4K, frame rates range from 17 to 34 FPS.
The Radeon HD 7870M is 63% below recommended, but 0% above minimum for Roblox. The Ryzen 7 7800X3D is 1465% above the recommended CPU (Core 2 Duo).
The Radeon HD 7870M sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Ryzen 7 7800X3D still has additional frame-generation headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k ultra, the Radeon HD 7870M sets the ceiling at about 17 FPS, while the Ryzen 7 7800X3D has headroom up to 205 FPS. In this scenario, the GPU limits the CPU potential by 92% (FPS gap: 188 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Radeon HD 7870M is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 7800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 80% | GPU Limits CPU 80% | GPU Limits CPU 83% | GPU Limits CPU 84% |
| 1440p (2K QHD) | GPU Limits CPU 82% | GPU Limits CPU 83% | GPU Limits CPU 87% | GPU Limits CPU 88% |
| 4K (Ultra HD) | GPU Limits CPU 87% | GPU Limits CPU 88% | GPU Limits CPU 91% | GPU Limits CPU 92% |
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 1465% below recommended and your GPU is 63% below recommended, but both meet minimum specs. Playable at Low/Medium settings, 1080p or below.

The Ryzen 7 7800X3D and Radeon HD 7870M will struggle to run Roblox at smooth framerates. At 1080p Ultra, you can expect around 34 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.
For Roblox, upgrading the GPU would give you the most noticeable improvement. The Radeon HD 7870M is the limiting factor here, while the Ryzen 7 7800X3D still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-limited 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 setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
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.
