RustFPS onRyzen Threadripper PRO 9985WX&GeForce RTX 4090

Rust

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.

Percentages show how much potential FPS of the stronger component is lost because the other component has a lower FPS ceiling.
🧠Methodology

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.

The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Frequently Asked Questions

1Can the Ryzen Threadripper PRO 9985WX and GeForce RTX 4090 run Rust well?

Yes, the Ryzen Threadripper PRO 9985WX paired with the GeForce RTX 4090 can run Rust smoothly up to 4k achieving around 83 FPS at Ultra quality. Your GPU is 244% above the recommended specs, and your CPU is 1159% above the recommended requirements.

2Is there a more cost-effective setup to run Rust?

This CPU + GPU combo costs approximately $9648 ($7999 CPU (Rank #378 Value) + $1649 GPU (Rank #77 Value)). Your Ryzen Threadripper PRO 9985WX provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end processor with a significantly better value rating.

3Which component should I upgrade first to improve Rust performance?

Your Ryzen Threadripper PRO 9985WX is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Rust performance right now. CPU fully utilized at: 1080p ultra, 4k medium.

4Does this setup support Frame Generation for Rust?

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.

5What are the minimum and recommended specs for Rust?

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 Threadripper PRO 9985WX and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.

6How accurate are these Rust FPS estimates for the Ryzen Threadripper PRO 9985WX and GeForce RTX 4090?

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.
