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, all quality settings exceed 91 FPS. At 1440p, all settings exceed 72 FPS. At 4K, frame rates range from 32 to 78 FPS.
The GeForce RTX 4090 is 244% above the recommended GPU (GeForce GTX 980) for Rust. The Core i7-10510Y is 64% below minimum CPU requirement.
The Core i7-10510Y sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p low, the Core i7-10510Y sets the ceiling at about 91 FPS, while the GeForce RTX 4090 could reach 245 FPS. In this scenario, the CPU limits the GPU potential by 63% (FPS gap: 154 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i7-10510Y is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 63% | CPU Limits GPU 60% | CPU Limits GPU 50% | CPU Limits GPU 43% |
| 1440p (2K QHD) | CPU Limits GPU 59% | CPU Limits GPU 56% | CPU Limits GPU 40% | CPU Limits GPU 43% |
| 4K (Ultra HD) | CPU Limits GPU 47% | CPU Limits GPU 51% | CPU Limits GPU 54% | CPU Limits GPU 62% |
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 hardware is below minimum requirements. CPU is the limiting factor (64% below minimum). Expect performance issues. Low settings recommended.

Yes, the Core i7-10510Y paired with the GeForce RTX 4090 can run Rust smoothly up to 1440p achieving around 72 FPS at Ultra quality. Your GPU is 244% above the recommended specs, and your CPU is 70% below the recommended requirements.
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 Rust, upgrading the CPU would have the biggest impact on performance. The Core i7-10510Y is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-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.
Rust 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.
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 hardware falls below the minimum requirements for this game, which may result in poor 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.
