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
Performance Report
At 1080p, frame rates range from 55 to 113 FPS depending on quality settings. At 1440p, frame rates range from 37 to 74 FPS. At 4K, frame rates range from 13 to 31 FPS.
The GeForce GTX 680 is 49% below recommended, but 1% above minimum for Rust. The Ryzen 7 7800X3D is 180% above the recommended CPU (Core i7-4790K).
Rust supports: AFMF. This game does not have native DLSS 3 or FSR 3 Frame Generation support. AFMF is AMD-exclusive and not compatible with GeForce GTX 680.
The GeForce GTX 680 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.
Approximated average price on current market:
Combo price: $424. At 1080p Ultra, this combo delivers 55 FPS, equivalent to 0.13 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k medium, the GeForce GTX 680 sets the ceiling at about 22 FPS, while the Ryzen 7 7800X3D has headroom up to 133 FPS. In this scenario, the GPU limits the CPU potential by 83% (FPS gap: 111 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce GTX 680 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 44% | GPU Limits CPU 60% | GPU Limits CPU 55% | GPU Limits CPU 63% |
| 1440p (2K QHD) | GPU Limits CPU 63% | GPU Limits CPU 73% | GPU Limits CPU 66% | GPU Limits CPU 68% |
| 4K (Ultra HD) | GPU Limits CPU 77% | GPU Limits CPU 83% | GPU Limits CPU 82% | GPU Limits CPU 83% |
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 180% below recommended and your GPU is 49% below recommended, but both meet minimum specs. Playable at Low/Medium settings, 1080p or below.

The Ryzen 7 7800X3D and GeForce GTX 680 will struggle to run Rust at smooth framerates. At 1080p Ultra, you can expect around 55 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $424 ($384 CPU (Rank #212 Value) + $40 GPU). Since the GPU is the main limiting factor, investing in a stronger GPU will improve your framerates and overall value. 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 GeForce GTX 680 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.
Rust supports AFMF, but your GeForce GTX 680 is not compatible with these technologies. Frame Generation is typically available on newer GPUs like the RTX 40-series (DLSS 3) or modern AMD cards (FSR 3).
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 setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
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.
