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 222 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 189 FPS. At 4K, all settings exceed 94 FPS.
The GeForce RTX 5090 is 251% above the recommended GPU (GeForce GTX 980) for Rust. The Core i9-9990XE is 146% above the recommended CPU (Core i7-4790K).
The Core i9-9990XE sets the FPS ceiling at all 1440p settings, all 4k settings, while the GeForce RTX 5090 still has headroom. The FPS ceiling is closely matched at all 1080p settings.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
This CPU/GPU pair is mostly balanced in Rust. Across tested presets: GPU limits in 0/12, CPU limits in 0/12, and balanced in 12/12. Peak observed performance in the sampled cells is around 350 FPS.
The Core i9-9990XE and GeForce RTX 5090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | Balanced | Balanced | Balanced | Balanced |
| 4K (Ultra HD) | Balanced | Balanced | Balanced | Balanced |
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 and then monotonic-smoothed across heavier presets and resolutions, 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 146% above and your GPU is 251% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Core i9-9990XE paired with the GeForce RTX 5090 can run Rust smoothly up to 4k achieving around 94 FPS at Ultra quality. Your GPU is 251% above the recommended specs, and your CPU is 146% above 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 i9-9990XE is currently the limiting factor — the GeForce RTX 5090 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: 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 Core i9-9990XE and GeForce RTX 5090 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.
