Rust

The Intel Core i5-12400F paired with the AMD Radeon RX 7900 XT delivers a wide range of performance in Rust, scaling from playable at 4K to exceptionally fast at 1080p. The data shows a system that is clearly capable of running the game smoothly at standard resolutions, with the primary trade-off occurring at the highest 4K settings where frame rates dip below the 60 FPS threshold.

Measured FPS Breakdown

The measured frame rates for this combination in Rust show a clear pattern of performance scaling across resolutions and settings. At 3840x2160, the average frame rates range from 43.8 FPS on the Ultra preset to 100.6 FPS on Low. The Medium preset achieves an average of 63.3 FPS, while High sits at 58.3 FPS. This places the 4K experience in a narrow band where only the Low and Medium presets clear the 60 FPS playability threshold, with High falling just short and Ultra requiring a significant compromise.

Moving to 2560x1440, the results improve substantially. The Low preset reaches an average of 164.6 FPS, which is nearly 64% higher than the 4K Low result. Medium delivers 115 FPS, High produces 92.5 FPS, and the Ultra preset achieves 69.5 FPS. All four presets at 1440p comfortably exceed the 60 FPS threshold, making this resolution the sweet spot for balancing visual fidelity and performance. The jump from 4K to 1440p at the same preset yields a performance increase of roughly 34 to 59 FPS depending on the settings level.

At 1920x1080, the combination performs exceptionally well across the board. The Low preset averages 205.6 FPS, which is the highest measured result in the entire data set. Medium follows at 164.8 FPS, High at 136.6 FPS, and even the most demanding Ultra preset maintains a strong 106.8 FPS average. Every setting at 1080p provides a frame rate well above 100 FPS, indicating that this resolution is not a limiting factor for the hardware. The scaling from 1440p to 1080p shows an additional performance gain of approximately 37 to 41 FPS at each preset level.

The data does not include minimum or maximum frame rate values, so the analysis relies solely on average FPS. This means that transient dips or spikes cannot be quantified, but the consistently high averages suggest that the system maintains stable performance in typical gameplay scenarios.

Best Settings per Resolution

For 3840x2160, the most demanding preset that stays at or above 60 FPS is Medium, which delivers an average of 63.3 FPS. The High preset falls slightly below the threshold at 58.3 FPS, and Ultra drops further to 43.8 FPS. Players targeting 4K should use Medium settings to maintain smooth gameplay, as this is the highest visual quality that meets the 60 FPS requirement.

At 2560x1440, the Ultra preset achieves an average of 69.5 FPS, making it the best settings choice for this resolution. All four presets — Low, Medium, High, and Ultra — remain above 60 FPS, so there is no performance-based reason to lower settings below Ultra. This gives users full freedom to maximize visual quality at 1440p without sacrificing playability.

For 1920x1080, the Ultra preset delivers an average of 106.8 FPS, which is the best settings option at this resolution. Similar to the 1440p results, every preset at 1080p exceeds the 60 FPS threshold, allowing users to select Ultra without any concerns about frame rate drops. The combination of high averages and the large headroom above 60 FPS means that even the most demanding settings are fully playable at 1080p.

CPU and GPU Roles

The performance scaling across resolutions reveals which component plays a larger role in Rust at each setting level. At 3840x2160, the frame rates show a clear dependency on GPU capability, as the gap between Low (100.6 FPS) and Ultra (43.8 FPS) is substantial at 56.8 FPS. This wide spread indicates that the GPU is the primary bottleneck at 4K, with the RX 7900 XT's raw rendering power determining the outcome. The CPU's role is less prominent at this resolution, as the higher pixel count shifts the workload heavily toward the graphics card.

At 2560x1440, the spread between Low (164.6 FPS) and Ultra (69.5 FPS) narrows to 95.1 FPS, but the relative pattern remains similar. The GPU still drives performance differences between presets, but the CPU begins to contribute more as the resolution decreases. The fact that Ultra still exceeds 60 FPS at 1440p suggests that neither component is severely limiting at this setting, and the system has enough headroom to handle the increased load.

At 1920x1080, the pattern shifts noticeably. The spread between Low (205.6 FPS) and Ultra (106.8 FPS) is 98.8 FPS, but the absolute frame rates are high enough that both components are likely operating near their limits. The CPU's influence becomes more apparent at this resolution, as the lower pixel count reduces GPU load and allows the i5-12400F to keep pace with frame generation. The high averages across all presets indicate that the CPU is sufficient to feed the GPU at 1080p, preventing it from becoming a bottleneck.

The scaling between resolutions provides further insight into component roles. Moving from 4K to 1440p at the same preset yields a performance increase of 34 to 64 FPS, while moving from 1440p to 1080p yields an additional 37 to 41 FPS. This diminishing return pattern suggests that the GPU is more heavily utilized at higher resolutions, while the CPU's contribution becomes more significant at lower resolutions. Overall, the data indicates that the RX 7900 XT is the dominant factor at 4K, while the i5-12400F plays a more balanced role at 1440p and 1080p.

The Verdict

This combination can run Rust successfully, with clear playable settings defined for each resolution. At 3840x2160, the system achieves playable performance on Low (100.6 FPS) and Medium (63.3 FPS) presets, with Medium being the best settings choice. The High preset at 58.3 FPS and Ultra at 43.8 FPS fall below the 60 FPS threshold, so they are not recommended for 4K gaming.

At 2560x1440, all four presets — Low (164.6 FPS), Medium (115 FPS), High (92.5 FPS), and Ultra (69.5 FPS) — exceed the 60 FPS requirement. The Ultra preset is the best choice here, delivering smooth performance alongside maximum visual quality. This makes 1440p the ideal resolution for this system, as it provides a comfortable margin above the playability threshold even at the highest settings.

At 1920x1080, the system performs exceptionally well, with all presets exceeding 100 FPS. Low averages 205.6 FPS, Medium 164.8 FPS, High 136.6 FPS, and Ultra 106.8 FPS. The Ultra preset is the best settings option, offering a high frame rate that is more than sufficient for smooth gameplay. The verdict is clear: this PC can run Rust at 60 FPS or higher across all tested resolutions, with the only limitation being that 4K users must select Medium or lower settings to maintain playability. For 1440p and 1080p users, there are no restrictions — every preset is playable, and the highest quality settings are recommended.
