The Celeron T3500 + GeForce RTX 4090 pairing runs this title with CPU utilization between 46% and 85% and GPU utilization between 17% and 56%. Celeron T3500 stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 29% at 1080p to 40% at 4K, while CPU averages move from 66% to 66%.
The utilization pattern is relatively even. The GeForce RTX 4090 reaches 42% average at its highest-load preset, while the Celeron T3500 peaks at 68% average. This suggests a fairly controlled load distribution, but the actual FPS-limiting side should still be read from the limiter analysis above.
At 1080p, averages sit around CPU 66% and GPU 29%. At 1440p, that shifts to CPU 66% and GPU 39%, and at 4K it reaches CPU 66% and GPU 40%. 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 66% (48-84%) and GPU 42% (27-56%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Celeron T3500 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Celeron T3500 and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

The Celeron T3500 and GeForce RTX 4090 will struggle to run Roblox at smooth framerates.
This CPU + GPU combo costs approximately $1659 ($10 CPU + $1649 GPU (Rank #77 Value)). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
This setup is already well-balanced for Roblox. No significant bottleneck - CPU and GPU are well matched across all settings. Both the Celeron T3500 and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
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 hardware falls below the minimum requirements for this game, which may result in poor 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.
