Rust

The Intel Core i9-14900K paired with the NVIDIA GeForce RTX 4090 delivers exceptional performance in Rust, with measured frame rates that far exceed the 60 FPS playability threshold across all tested resolutions and presets. The data shows a system that is heavily overqualified for this title, but the specific margins of headroom vary significantly depending on the resolution and graphical settings chosen. At 3840x2160, the combo averages 75 FPS on High settings, 89.6 FPS on Medium, and 128.6 FPS on Low, while the Ultra preset dips to an average of 56.2 FPS, narrowly missing the playable mark. Moving to 2560x1440, the frame rates rise substantially: 126 FPS on High, 146 FPS on Medium, 221.8 FPS on Low, and 92.4 FPS on Ultra. At 1920x1080, the performance is even more impressive, with the Ultra preset averaging 136.7 FPS, High at 178.9 FPS, Medium at 212.1 FPS, and Low at 275.2 FPS.

Measured FPS Breakdown

The measured FPS data for this combination reveals a clear pattern of performance scaling across resolutions and settings. At 3840x2160, the system produces an average of 128.6 FPS on Low settings, which represents the highest frame rate at this resolution. The Medium preset delivers 89.6 FPS, while High settings yield 75 FPS. The Ultra preset at 4K is the only configuration in the entire dataset that falls below the 60 FPS threshold, with an average of 56.2 FPS. This indicates that while the RTX 4090 is powerful enough for most 4K scenarios, Rust's Ultra preset at this resolution imposes a substantial load that even this flagship GPU cannot fully overcome.

At 2560x1440, the performance headroom expands considerably. Low settings produce an average of 221.8 FPS, which is nearly four times the playability threshold. Medium settings average 146 FPS, and High settings average 126 FPS. The Ultra preset, which struggled at 4K, achieves a comfortable 92.4 FPS average at this resolution. The scaling from 4K to 1440p shows an approximate 65% improvement in frame rate for the Ultra preset (from 56.2 to 92.4 FPS), while the Low preset improves by roughly 72% (from 128.6 to 221.8 FPS).

The 1920x1080 results demonstrate that this combination is essentially unconstrained at lower resolutions. The Low preset averages 275.2 FPS, Medium averages 212.1 FPS, High averages 178.9 FPS, and even the demanding Ultra preset maintains an average of 136.7 FPS. The difference between 1440p and 1080p is notable but smaller than the jump from 4K to 1440p: the Ultra preset improves by about 48% (from 92.4 to 136.7 FPS), while the Low preset improves by about 24% (from 221.8 to 275.2 FPS). This diminishing scaling suggests that at lower resolutions, the CPU begins to play a more significant role in limiting frame rates, as the GPU has ample headroom.

Best Settings per Resolution

At 3840x2160, the best playable setting is High, which achieves an average of 75 FPS. This is the most demanding preset that maintains a frame rate above the 60 FPS threshold. While Medium and Low also remain playable at 89.6 and 128.6 FPS respectively, High offers the best balance of visual quality and performance. Ultra at 4K should be avoided, as it averages only 56.2 FPS.

For 2560x1440, the Ultra preset is the recommended choice, averaging 92.4 FPS. This provides the highest visual fidelity while still delivering smooth gameplay. The High preset at 126 FPS and Medium at 146 FPS offer higher frame rates for competitive play, but they do not provide the same visual quality as Ultra.

At 1920x1080, Ultra is again the best setting, with an average of 136.7 FPS. This is well above the 60 FPS threshold and provides the full visual experience. The lower presets all offer even higher frame rates, with Low reaching 275.2 FPS, which would be beneficial for players using high-refresh-rate monitors or seeking the absolute lowest input latency.

The Verdict

This PC can absolutely run Rust, and it does so with substantial headroom at most settings. The verdict data confirms that at 1920x1080, all four presets (Low, Medium, High, and Ultra) are playable, with the Ultra preset averaging 136.7 FPS. At 2560x1440, the same is true: all presets are playable, with Ultra averaging 92.4 FPS. At 3840x2160, three of the four presets are playable (Low at 128.6 FPS, Medium at 89.6 FPS, and High at 75 FPS), but Ultra falls to 56.2 FPS, which is below the playable threshold.

The system's ability to handle Ultra settings at 1440p and 1080p, while requiring a drop to High at 4K, demonstrates that it is well-suited for Rust in virtually all gaming scenarios. The only limitation is the 4K Ultra preset, which represents the most demanding configuration possible for this title. For players who prioritize frame rate over visual fidelity, even the 4K Low preset provides a highly responsive 128.6 FPS average.

CPU and GPU Roles

The data reveals an interesting dynamic between CPU and GPU load across resolutions. At 3840x2160, the GPU is clearly the limiting factor, as evidenced by the Ultra preset dropping to 56.2 FPS while the CPU remains capable of much higher performance. The scaling from 4K to 1440p shows a dramatic improvement in frame rates across all settings, indicating that the GPU has significant headroom at lower resolutions. For example, the Ultra preset improves from 56.2 FPS at 4K to 92.4 FPS at 1440p, a 64% increase, which is primarily due to the reduced pixel count.

At 1920x1080, the scaling becomes less pronounced, suggesting that the CPU begins to play a larger role. The Ultra preset improves from 92.4 FPS at 1440p to 136.7 FPS at 1080p, a 48% increase, while the Low preset improves from 221.8 to 275.2 FPS, only a 24% increase. This diminishing return indicates that at 1080p, the Core i9-14900K's processing power is becoming a more significant factor, as the RTX 4090 has more than enough capacity to render the frame at lower resolutions.

The Core i9-14900K's benchmark scores support its role as a capable partner: it achieves a Cinebench R23 multi-core score of 39,399.5 and a single-core score of 2,262.5, alongside a Geekbench single-core score of 2,655. These results place it at the 95th percentile among all CPUs, ensuring that it can keep pace with the RTX 4090's output at any resolution. The CPU's 24 cores and 32 threads, with a boost clock of 6.00 GHz, provide ample processing power for Rust's simulation and world-generation tasks. For players using 1080p or 1440p displays, the GPU will be the primary driver of performance, while at 4K, the GPU's raw throughput becomes the deciding factor.
