Rust

The AMD Ryzen 9 5900X and NVIDIA GeForce RTX 4080 combination delivers strong performance in Rust, with the data showing playable frame rates across all tested resolutions and settings, though the most demanding preset at 4K falls just short of the 60 FPS threshold. This analysis walks through the measured FPS data, component scaling, and how this pairing ranks against other tested configurations.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is High, which produces an average of 66 FPS. The Medium preset runs at 79 FPS, and Low reaches 117 FPS, but Ultra drops to 50 FPS, which falls below the playable threshold. The data shows that High is the optimal balance for 4K, keeping the average frame rate comfortably above 60 FPS while still offering substantial visual quality. Pushing to Ultra at this resolution costs 16 FPS compared to High, a 24% reduction that crosses the playability line.

At 2560x1440, the situation improves significantly. Ultra settings deliver an average of 85 FPS, making it the best setting that clears the 60 FPS mark. High runs at 112 FPS, Medium at 133 FPS, and Low at 179 FPS. The jump from 4K to 1440p allows the system to handle Ultra without issue, and the 85 FPS average leaves headroom for demanding scenes. Even the most intensive preset at this resolution stays well above the playable threshold.

At 1920x1080, all four presets exceed 60 FPS, and Ultra is the best choice with an average of 124 FPS. High runs at 163 FPS, Medium at 175 FPS, and Low at 203 FPS. The 1080p results show that this combination has substantial performance reserves, with even the heaviest settings nearly doubling the 60 FPS target. The data indicates that players at this resolution can enable maximum settings without worrying about frame rate drops.

CPU and GPU Roles

The scaling between resolutions and presets reveals how the CPU and GPU share the workload in Rust. At 1920x1080, the difference between Low and Ultra is 79 FPS (203 down to 124), which is a 39% drop. At 2560x1440, the same preset range shows a 94 FPS difference (179 down to 85), a 53% reduction. At 3840x2160, the gap widens further: 117 FPS at Low versus 50 FPS at Ultra, a 57% decline. This pattern indicates that the GPU becomes more dominant as resolution increases, since higher pixel counts place more strain on the graphics card.

The CPU role is most visible at lower resolutions. At 1080p, the Ryzen 9 5900X with its 12 cores and 24 threads keeps the frame rates high across all settings, but the scaling from Low to Ultra shows that even with a strong CPU, the GPU still drives the largest performance swings. At 4K, the CPU matters less because the GPU is the primary bottleneck; the 5900X provides enough headroom to avoid holding back the RTX 4080.

Comparing across resolutions at the same setting reinforces this. For High settings, moving from 1080p (163 FPS) to 1440p (112 FPS) is a 31% drop, and from 1440p to 4K (66 FPS) is another 41% reduction. For Low settings, the drops are 12% from 1080p to 1440p (203 to 179 FPS) and 35% from 1440p to 4K (179 to 117 FPS). The larger percentage drops at higher resolutions for the same preset confirm that the GPU is the limiting factor in 4K scenarios.

Measured FPS Breakdown

At 3840x2160, the measured data shows the following averages: Low runs at 117 FPS, Medium at 79 FPS with a minimum of 67 and maximum of 90, High at 66 FPS, and Ultra at 50 FPS. The Medium preset provides the only min/max data in this resolution, showing a 23 FPS spread between the lowest and highest observed frames. The progression from Low to Ultra is steady, with each step up in quality reducing the average by roughly 15 to 29 FPS. The Ultra preset falls below the 60 FPS playable threshold, making it unsuitable for smooth gameplay at this resolution.

At 2560x1440, the averages are much higher: Low at 179 FPS, Medium at 133 FPS with a minimum of 113 and maximum of 153, High at 112 FPS, and Ultra at 85 FPS. The Medium preset again offers min/max figures, with a 40 FPS spread. The drop from Low to Ultra is 94 FPS, but even the lowest average (Ultra at 85 FPS) remains well above the playable threshold. This resolution provides the best balance of visual quality and performance, with every preset clearing 60 FPS by a wide margin.

At 1920x1080, the data shows: Low at 203 FPS, Medium at 175 FPS with a minimum of 148 and maximum of 201, High at 163 FPS, and Ultra at 124 FPS. The Medium preset has a 53 FPS spread between minimum and maximum, which is the largest variation observed across all resolutions. Even the Ultra preset at 124 FPS is more than double the playable threshold, indicating that this combination can handle 1080p gaming with substantial room to spare. The scaling from Low to Ultra is 79 FPS, the smallest absolute drop among the three resolutions, which again points to the CPU’s stronger influence at lower pixel counts.

The Verdict

The verdict by resolution is clear from the data. At 3840x2160, the playable settings are High, Low, and Medium, with High being the best at 66 FPS. Ultra does not clear the 60 FPS threshold, so players at 4K must choose between High and Medium for smooth gameplay. The 66 FPS average at High provides a stable experience, though the 50 FPS at Ultra shows that maxing out the game at this resolution is not viable.

At 2560x1440, all four presets are playable, and Ultra is the best setting with an 85 FPS average. This resolution offers the full range of options, from Low at 179 FPS to Ultra at 85 FPS, all above the 60 FPS line. Players can use maximum settings without compromise, and the 85 FPS average at Ultra leaves headroom for demanding scenes or background processes.

At 1920x1080, every preset exceeds 60 FPS, with Ultra as the best at 124 FPS. The lowest average in this resolution is Ultra’s 124 FPS, which is still more than double the playable threshold. This combination can run Rust at maximum settings with excellent frame rates, making 1080p the most comfortable resolution for this hardware. Overall, the data shows that this PC runs Rust well at 1440p and 1080p with full settings, and at 4K with High or lower presets.
