Rust

The Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 4080 Mobile delivers a compelling, though not flawless, Rust experience. The dataset reveals a system that is heavily GPU-limited at higher resolutions, while the CPU proves adequate for high-refresh-rate 1080p play. The measured frames per second (FPS) across the three resolutions and four settings presets provide a clear picture of where this combination excels and where its performance ceiling resides.

Resolution Scaling

The FPS data across the three tested resolutions—1920x1080, 2560x1440, and 3840x2160—demonstrates a classic performance curve dominated by the GPU's rendering load. At the "Ultra" preset, the average FPS drops from 89 at 1080p to 61 at 1440p, a 31.5% reduction, and then to 36 at 4K, a further 41% reduction from the 1440p figure. This steep decline as pixel count increases is the signature of a GPU-bound scenario, where the RTX 4080 Mobile's raw throughput is the limiting factor.

The scaling pattern shifts when examining the "Low" preset. Here, the average FPS at 1080p is 204, which falls to 142 at 1440p and 84 at 4K. The relative drop from 1080p to 1440p is 30.4%, which is nearly identical to the drop seen on the "Ultra" preset. However, the absolute numbers are much higher, suggesting that while the GPU is still the primary constraint, the workload is less demanding. The fact that the 4K "Low" average of 84 FPS is still higher than the 1080p "Ultra" average of 89 FPS is telling. It indicates that the graphical settings have a more profound impact on the frame rate than the resolution itself, a clear sign that the GPU is working hard but not fully saturated until the highest settings are engaged.

The "Medium" preset provides the most granular data, with minimum and maximum FPS values recorded. At 1080p, the average is 139 FPS with a minimum of 118 and a maximum of 159. Moving to 1440p, the average drops to 95 FPS (min 81, max 110), and at 4K, it falls to 56 FPS (min 48, max 65). The consistent drop of roughly 40 FPS between 1080p and 1440p, and another 39 FPS between 1440p and 4K, underscores the linear scaling of the GPU load. The range between minimum and maximum FPS also narrows as resolution increases, indicating that frame time variance becomes less pronounced when the GPU is more consistently saturated.

The data indicates that at 1080p, the system is capable of pushing frame rates well beyond the 144Hz mark on lower settings, making it highly responsive. At 1440p, it remains a strong performer for high-refresh-rate monitors, particularly on "High" and "Medium" settings. The 4K experience is playable but demands the "Low" or "Medium" presets to maintain smooth frame rates, as the "High" and "Ultra" presets fall below the 60 FPS threshold. The limiting component at 4K is unequivocally the GPU, as the CPU's performance headroom is not the bottleneck at these pixel counts.

Settings Recommendations

The benchmark results suggest that the optimal experience balances visual fidelity with frame rate stability. For players targeting 60 FPS as a baseline, the "Medium" preset is the clear choice at 1440p, delivering an average of 95 FPS with a minimum of 81. This preset offers a significant visual upgrade over "Low" while maintaining a comfortable margin above the 60 FPS target. At 1080p, the "High" preset provides an average of 117 FPS, which is an excellent balance for competitive play on high-refresh-rate displays, sacrificing only a small amount of performance compared to "Medium" (139 FPS) for a substantial graphical improvement.

At 4K, the "Medium" preset is the only viable option for a consistently smooth experience, with an average of 56 FPS and a minimum of 48. While not a locked 60 FPS, it is playable. The "Low" preset at 4K is the safer bet for a more stable frame rate, averaging 84 FPS, but it will compromise the visual quality significantly. The "Ultra" preset is generally not recommended at any resolution if frame rate is a priority, as it is the only preset that drops below 60 FPS at 1440p (61 FPS average) and falls to a demanding 36 FPS average at 4K.

For most users, the "High" preset at 1440p appears to be the "sweet spot" for this hardware combination. It achieves an 81 FPS average, which is a smooth experience, while providing a high level of graphical detail. At 1080p, "High" is also excellent, but the jump to "Ultra" (89 FPS average) is a modest 24% performance cost for the highest fidelity, which may be acceptable for players who prioritize visuals over maximum frame rates. The data strongly suggests that "Ultra" is a showcase preset for this combo, not a competitive one.

FAQ

Q: Can this system run Rust at 4K with high settings?

GPU Role

The NVIDIA GeForce RTX 4080 Mobile is the dominant component in this system. It features 7424 shading units, 58 RT cores, and 232 tensor cores based on the Ada Lovelace architecture. Its 12 GB of GDDR6 memory on a 192-bit bus provides a bandwidth of 432.0 GB/s, which is a significant asset for high-resolution texture streaming. The GPU's boost clock of 1665 MHz and its 24.72 TFLOPS of FP32 compute power are the primary drivers of the FPS figures observed.

The GPU's performance is the main factor in the FPS scaling seen across resolutions. The transition from 1080p to 1440p to 4K increases the pixel shading workload, which directly impacts the GPU's frame rendering time. The data shows that the RTX 4080 Mobile can handle 1080p and 1440p with ease, but at 4K, its performance drops to the point where settings must be lowered to maintain a high frame rate. The "Ultra" preset at 4K, with an average of 36 FPS, demonstrates the GPU's limit when pushed with maximum visual effects and a high pixel count.

The GPU's 81st percentile ranking among all GPUs, and its average benchmark score of 38135, place it in a high-performance tier. Its nearest rival, the NVIDIA GeForce RTX 5080 Mobile, has a nearly identical average score (38349), a difference of only 0.6%. This indicates that the RTX 4080 Mobile is a top-tier mobile GPU, and its performance in Rust reflects that. The GPU's 12 GB of VRAM is not a limiting factor in these benchmarks, as the game's memory usage at these settings does not appear to exceed that capacity. The RTX 4080 Mobile is unequivocally the star of this show, and its capabilities define the overall gaming experience.
