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 1080p low, the Core i5-14600T sets the ceiling at about 254 FPS, while the GeForce RTX 4090 could reach 270 FPS. In this scenario, the CPU limits the GPU potential by 6% (FPS gap: 16 FPS). Overall distribution: CPU limits 1/12 cells, GPU limits 0/12, balanced 11/12. Confidence is low because both ceilings are very close in this cell.
The Core i5-14600T and GeForce RTX 4090 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) | CPU Limits GPU 6% | 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, not generic utilization heuristics.

The Core i5-14600T + GeForce RTX 4090 pairing runs this title with CPU utilization between 26% and 54% and GPU utilization between 61% and 99%. Core i5-14600T keeps significant headroom across presets, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 77% at 1080p to 90% at 4K, while CPU averages move from 44% to 42%.
From a utilization perspective, this is a GPU-heavy load profile. At 4K (Ultra HD) High, the GeForce RTX 4090 averages 98% usage (96-99%), while the Core i5-14600T stays at 44% (33-54%). This shows the graphics pipeline is carrying most of the workload, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 44% and GPU 77%. At 1440p, that shifts to CPU 44% and GPU 78%, and at 4K it reaches CPU 42% and GPU 90%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
1440p (2K QHD) High is the most balanced preset based on this dataset. It runs around CPU 44% (34-54%) and GPU 86% (80-91%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core i5-14600T remains stable for consistent frame delivery.
Upgrade priority should be the GPU. The GeForce RTX 4090 reaches 98% average load at 4K (Ultra HD) High while the Core i5-14600T still has headroom, so a faster graphics card would deliver the largest uplift.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the Core i5-14600T paired with the GeForce RTX 4090 can run Rust smoothly up to 4k achieving around 96 FPS at Ultra quality. Your GPU is 244% above the recommended specs, and your CPU is 122% above the recommended requirements.
This CPU + GPU combo costs approximately $1904 ($255 CPU (Rank #164 Value) + $1649 GPU (Rank #77 Value)). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
This setup is already well-balanced for Rust. No significant bottleneck - CPU and GPU are well matched across all settings. Both the Core i5-14600T and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
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 i5-14600T and GeForce RTX 4090 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.
