A true test for system memory. Procedural maps can exhaust RAM quickly; 16GB is the minimum, and 32GB is recommended. CPUs with 3D V-Cache (AMD X3D) offer massive performance gains here.
Actual FPS may vary based on RAM speed, background processes, and other system factors

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k high, the Radeon RX 6600 LE sets the ceiling at about 29 FPS, while the Ryzen 7 7800X3D has headroom up to 107 FPS. In this scenario, the GPU limits the CPU potential by 73% (FPS gap: 78 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Radeon RX 6600 LE 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 33% | GPU Limits CPU 37% | GPU Limits CPU 35% | GPU Limits CPU 36% |
| 1440p (2K QHD) | GPU Limits CPU 48% | GPU Limits CPU 53% | GPU Limits CPU 48% | GPU Limits CPU 46% |
| 4K (Ultra HD) | GPU Limits CPU 68% | GPU Limits CPU 71% | GPU Limits CPU 73% | GPU Limits CPU 70% |
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.

Yes, the Ryzen 7 7800X3D paired with the Radeon RX 6600 LE can run Rust smoothly up to 1440p achieving around 81 FPS at Ultra quality. Your GPU is 24% above the recommended specs, and your CPU is 180% above the recommended requirements.
This CPU + GPU combo costs approximately $544 ($384 CPU (Rank #212 Value) + $160 GPU (Rank #24 Value)). Your build is already very cost-efficient, but if you want even more FPS, the next good option is upgrading the GPU. For example, upgrading to the GeForce RTX 5060 for around $299 (Rank #2 for value) could deliver noticeably better performance.
For Rust, upgrading the GPU would give you the most noticeable improvement. The Radeon RX 6600 LE 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 high, 1080p low, 1080p medium, 1080p ultra, 1440p high, 1440p low, 1440p medium, 1440p ultra, 4k high, 4k low, 4k medium, 4k ultra.
Yes! Rust supports AFMF, and your Radeon RX 6600 LE is compatible with AFMF. With Frame Generation enabled, you can expect a 1.5x-2x FPS multiplier on top of native framerates, significantly boosting perceived smoothness.
Rust requires at minimum a Core i7-3770 (CPU) and GeForce GTX 670 (GPU) with 10 GB RAM and 25 GB (SSD) storage. For the recommended experience, you need a Core i7-4790K and GeForce GTX 980 with 16 GB RAM. Your Ryzen 7 7800X3D and Radeon RX 6600 LE both exceed the recommended specs, so you're well-positioned for a great experience.
These Rust 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.
