Rust

Rust’s measured performance with the AMD Ryzen 9 9900X and AMD Radeon RX 7800 XT shows a system that is heavily GPU-limited at higher resolutions, but capable of exceptional frame rates at 1080p. The data reveals a clear hierarchy: at 1080p Low, the combo achieves 199.5 FPS, but this drops to 32.9 FPS at 4K Ultra, indicating that the GPU is the primary bottleneck as resolution and settings increase. The combo ranks 600th out of 1717 tested combinations, placing it in the upper third of all systems, though the CPU and GPU individually perform near their respective peer groups.

Resolution Scaling

The frame rate scaling from 1080p to 4K demonstrates a classic GPU-bound scenario. At 1080p Low, the system produces 199.5 FPS, which is an excellent result for a competitive survival game. Moving to 1440p Low, the average drops to 136.5 FPS, a reduction of 31.6% as pixel count increases. At 4K Low, the average falls further to 81.2 FPS, representing a 59.3% drop from the 1080p Low figure. This steep decline with resolution is characteristic of a GPU bottleneck, as the CPU has ample headroom at lower resolutions.

The gap between settings widens dramatically at higher resolutions. At 1080p, the difference between Low (199.5 FPS) and Ultra (86.4 FPS) is 113.1 FPS. At 1440p, this gap narrows to 78.4 FPS (136.5 vs 58.1), and at 4K it shrinks to 48.3 FPS (81.2 vs 32.9). This convergence indicates that at 4K, both resolution and settings are pushing the GPU to its limits, leaving less performance headroom for settings adjustments. The data suggests that for maximum frame rates, playing at 1080p with lower settings is the optimal strategy, while 4K is only viable with Low settings.
