Rust

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce GTX 1660 Ti delivers a playable, if not consistently smooth, experience in Rust, with the data showing that the Low preset is the only reliable path to high refresh rates at mainstream resolutions. The measured frames per second (FPS) reveal a system that is heavily constrained by the graphics card, particularly as resolution and settings escalate, making preset selection the single most impactful decision for playability.

Settings Recommendations

The benchmark results are unequivocal: the Low preset is the recommended setting for this combination across all tested resolutions. At 1920x1080, the Low preset produces an average of 108.9 FPS, which is the only configuration in the entire dataset to break the 100 FPS barrier. This provides a significant cushion for the CPU-bound moments common in Rust's busy servers, where frame times can spike. The Medium preset at 1080p is the next best option, delivering 72.3 FPS, which is playable but leaves less headroom. The High preset at 1080p drops to 62.2 FPS, still acceptable for a survival title, but the Ultra preset falls to 43.6 FPS, which is a substantial hit.

The case for Low becomes even more compelling at higher resolutions. At 2560x1440, the Low preset maintains an average of 76.3 FPS, a figure that remains fluid. The Medium preset at 1440p drops to 48.9 FPS, while High yields 43.5 FPS and Ultra falls to 33.7 FPS. At 3840x2160, no preset achieves a truly playable framerate. Low leads with 44.8 FPS, followed by High at 27.5 FPS, Medium at 27.2 FPS, and Ultra at a near-unplayable 19.9 FPS. The data suggests that for a consistent 60 FPS experience, users should stick to 1080p with the Low preset; for 1440p, Low is the only option that approaches smoothness; and 4K is generally not viable for this pairing.

How This Combo Ranks

Within the database of tested combinations for Rust, this specific pairing of the Ryzen 5 4600G and GTX 1660 Ti ranks at position 1462 out of 1717 total combinations. This places it in the lower percentile of tested systems, indicating that while it is capable of running the game, it does not represent a high-performance configuration. The rank is a composite measure of the system's overall capability in Rust, and the FPS data supports this positioning—it is a mid-to-low tier setup that can manage playable framerates only with significant compromises to visual quality.

The rank of 1462 out of 1717 is a clear indicator that the system is closer to the bottom of the performance spectrum than the top. This is not a surprising result given the components involved. The Ryzen 5 4600G is a CPU that sits in the 75th percentile when compared to all CPUs in the benchmark database, suggesting it is a reasonably capable processor. However, the GTX 1660 Ti only reaches the 55th percentile among all GPUs, and its performance relative to its immediate rivals shows it is barely keeping pace with much older hardware. The GPU is the limiting factor, and the combo's low rank in Rust reflects the game's heavy reliance on GPU throughput at the settings tested.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is built on the Turing architecture with a TU116 chip and 6 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 288.0 GB/s. The card's base clock is 1500 MHz, with a boost clock of 1770 MHz. This configuration places it in the 55th percentile of all GPUs, and its average benchmark score of 13925 is nearly identical to the AMD Radeon RX 570X, which scores 13871 (a delta of just 0.4%). It also edges out the NVIDIA RTX A2000 Mobile (13821) and the GeForce GTX 680 (13812) by a slim 0.8% margin.

The data indicates that the GPU's role in Rust is absolutely critical. The measured FPS drops dramatically as settings increase, which is a classic sign of a GPU bottleneck. At 1080p, the difference between Low and Ultra is 65.3 FPS (108.9 vs 43.6), a performance penalty of over 60% for the highest visual quality. This steep decline is directly attributable to the GTX 1660 Ti's compute capabilities, which are taxed heavily by the more demanding shaders and effects at higher presets. The 6 GB VRAM buffer is sufficient for 1080p and 1440p at these settings, but the raw processing power of the TU116 chip is the primary constraint, preventing the system from achieving high framerates at anything above the Low preset.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the system's performance envelope. Starting at 1920x1080, the results are as follows: Low averages 108.9 FPS, Medium averages 72.3 FPS, High averages 62.2 FPS, and Ultra averages 43.6 FPS. The transition from Low to Medium incurs a 36.6 FPS drop, while moving from Medium to High costs 10.1 FPS, and from High to Ultra costs another 18.6 FPS. This shows that the largest single performance hit comes from the initial step up from Low, while the High to Ultra transition also carries a heavy penalty.

Moving to 2560x1440, the framerates scale down predictably. Low averages 76.3 FPS, Medium 48.9 FPS, High 43.5 FPS, and Ultra 33.7 FPS. The gap between Low and Medium widens in percentage terms, with a 27.4 FPS drop. The High preset at 1440p is nearly identical to the Ultra preset at 1080p, which illustrates the combined stress of increased resolution and settings. At 3840x2160, the system struggles. Low drops to 44.8 FPS, High to 27.5 FPS, Medium to 27.2 FPS, and Ultra to 19.9 FPS. The data shows that at 4K, even the Low preset fails to provide a smooth experience, and the Ultra preset is effectively a slideshow.

Resolution Scaling

The scaling from 1080p to 4K reveals the nature of the bottleneck. At the Low preset, the average FPS drops from 108.9 at 1080p to 76.3 at 1440p, a 29.9% reduction, and then to 44.8 at 4K, a further 41.3% reduction from the 1440p figure. This is a steep and consistent decline that points directly to the GPU. If the CPU were the limiting factor, the framerate would not degrade so dramatically as pixel count increases, because the CPU workload would remain relatively constant. The fact that the FPS nearly halves from 1440p to 4K at Low settings demonstrates that the GTX 1660 Ti is saturated.

At the Ultra preset, the decline is even more severe. The system produces 43.6 FPS at 1080p, 33.7 FPS at 1440p, and 19.9 FPS at 4K. The percentage drop from 1080p to 1440p is 22.7%, and from 1440p to 4K is 40.9%. The increasing severity of the drop at higher resolutions confirms that the GPU's fill rate and memory bandwidth are the limiting factors. The Ryzen 5 4600G, with its 6 cores and 12 threads and a boost clock of 4.20 GHz, is likely providing sufficient data to the GPU, but the graphics card cannot process it fast enough at higher resolutions. The data strongly suggests that for this combo, resolution scaling is a direct indicator of GPU headroom, and there is very little of it beyond 1080p.
