Settings Recommendations

The measured data reveals a clear hierarchy of performance across presets. At 1920x1080, Low settings deliver 175 FPS, Medium 150 FPS, High 141 FPS, and Ultra 124 FPS. The jump from Low to Medium costs 25 FPS, while the jump from Medium to Ultra costs another 26 FPS, showing a relatively linear trade-off at this resolution.

At 2560x1440, the scaling becomes more pronounced: Low achieves 154 FPS, Medium 133 FPS, High 112 FPS, and Ultra drops to 85 FPS. The difference between Medium and High is 21 FPS, while High to Ultra costs 27 FPS. This suggests that High settings at 1440p offer a reasonable balance, but the Ultra preset introduces a significant performance hit that may not justify the visual gains.

For 3840x2160, the picture changes dramatically. Low delivers 117 FPS, Medium 79 FPS, High 66 FPS, and Ultra plummets to 50 FPS. The gap between Low and Medium is 38 FPS, the largest percentage drop across all resolutions. At 4K, even Medium settings cut performance nearly in half compared to Low, making Low the only viable preset for smooth gameplay above 100 FPS.

The data implies that the optimal experience depends heavily on target resolution. For 1080p, Medium or High provides excellent frame rates above 140 FPS without sacrificing too much visual quality. At 1440p, High at 112 FPS is the sweet spot, balancing smoothness with fidelity. For 4K, Low at 117 FPS is the only preset that maintains high refresh rates, as Medium already dips to 79 FPS with a min of 67 FPS.

Benchmark results indicate that Medium settings at 1440p (133 FPS) provide the best overall experience when considering both frame rate and visual quality. This preset offers a 21 FPS advantage over High while remaining visually acceptable for most players. The Ultra preset should be avoided at all resolutions above 1080p, as it sacrifices more than 40% of performance compared to High.

Resolution Scaling

The FPS progression from 1080p to 4K reveals important insights about the limiting component in this combo. At Low settings, average FPS drops from 175 at 1080p to 154 at 1440p (a 12% decrease) and then to 117 at 4K (a 24% further decrease). This relatively modest scaling at Low suggests the CPU is still a significant factor at lower resolutions, preventing the GPU from being fully utilized.

At High settings, the drop is more dramatic: 141 FPS at 1080p falls to 112 FPS at 1440p (a 21% decrease) and then to 66 FPS at 4K (a 41% further decrease). The steeper decline at higher settings indicates that the GPU becomes the primary bottleneck as resolution increases, with the RTX 4080 struggling to maintain high frame rates at 4K with High presets.

Medium settings show a similar pattern: 150 FPS at 1080p, 133 FPS at 1440p (an 11% drop), and 79 FPS at 4K (a 41% further drop). The consistency of the 4K penalty across Medium and High suggests that the GPU is hitting a compute ceiling around 4K, regardless of the moderate settings differences.

Ultra settings exhibit the worst scaling: 124 FPS at 1080p drops to 85 FPS at 1440p (a 31% decrease) and then to 50 FPS at 4K (a 41% further decrease). The data shows that Ultra at 4K is essentially unplayable for competitive purposes, while Ultra at 1440p remains borderline acceptable.

The resolution scaling data strongly indicates that the Intel Core i5-11400F is the limiting factor at 1080p, particularly at Low settings where the GPU is not fully stressed. As resolution increases, the RTX 4080's workload grows, and the CPU bottleneck diminishes. At 4K, the GPU is clearly the dominant constraint, with frame rates dropping by roughly 40% from 1440p to 4K across all settings except Low.

How This Combo Ranks

The combo rank of 557 out of 3,723 tested combinations places this setup in the 85th percentile of all recorded configurations in Rust. This is a strong showing, but the data reveals that there is substantial headroom above this combo in the rankings. The top 556 combinations likely feature newer CPUs or higher-end GPUs, though the specific details of those combos are not in the data.

The CPU's percentile of 71 among all CPUs suggests that the i5-11400F is slightly above average but not exceptional. Its nearest rivals include the AMD EPYC 7H12 (0.3% higher score), Intel Core i5-12450H (0.4% lower), and AMD Ryzen 3 PRO 8300G (0.6% lower). The tight clustering of these scores indicates that the i5-11400F is in a highly competitive mid-range segment.

The GPU's percentile of 86 among all GPUs is notably higher, with the RTX 4080 sitting just 0.1% above the RTX 4080 SUPER and 2.6% below the AMD Radeon RX 6750 GRE 12 GB in average benchmark scores. This suggests that the GPU is the stronger component in this pairing, likely contributing more to the combo's overall rank than the CPU.

The discrepancy between GPU percentile (86) and CPU percentile (71) implies that the combo's rank of 557 is limited by the CPU in Rust. The game appears to be CPU-sensitive in certain scenarios, as evidenced by the modest FPS gains from Low to High settings at 1080p (175 to 141 FPS, a 19% difference). A stronger CPU could potentially push this combo higher in the rankings, though the data does not specify how much headroom exists.

GPU Role

The RTX 4080's 16 GB of GDDR6X memory on a 256-bit bus provides 716.8 GB/s of bandwidth, which is substantial for Rust's open-world environments. The GPU's base clock of 2205 MHz and boost clock of 2505 MHz, combined with 9,728 shading units, delivers 48.74 TFLOPS of FP32 compute. These specifications suggest the GPU is well-equipped for high-resolution rendering.

In Rust, the GPU's role becomes increasingly dominant as resolution increases. At 4K, the measured FPS drops from 117 at Low to 50 at Ultra, a 57% reduction. This scaling indicates that the GPU is the primary bottleneck at 4K, with the 16 GB VRAM likely being sufficient but the compute throughput limiting performance at higher presets.

The GPU's memory bandwidth of 716.8 GB/s is particularly relevant for Rust, which features large, procedurally generated maps with extensive texture streaming. The data shows that Medium settings at 4K (79 FPS) outperform High settings at 4K (66 FPS) by 20%, suggesting that the GPU's texture fill rate and shading capabilities are stressed by High presets.

The RTX 4080's 76 RT cores and 304 tensor cores are present, though Rust does not heavily utilize ray tracing in the measured configurations. The GPU's 112 ROPs and 304 TMUs handle rasterization efficiently, as evidenced by the strong performance at 1080p Low (175 FPS) where the GPU is not fully taxed.

Benchmark results indicate that the RTX 4080's average score of 54,247 places it in the 86th percentile of all GPUs. The fact that it is only 0.1% ahead of the RTX 4080 SUPER suggests that the non-SUPER variant is already performing at near-peak efficiency for its architecture, with no meaningful headroom for driver-level improvements.

Measured FPS Breakdown

At 1920x1080, the combo achieves the following average FPS: Low 175, Medium 150 (min 128, max 173), High 141, and Ultra 124. The Medium preset shows a 45 FPS range between min and max, indicating significant scene-to-scene variation. Low settings provide the highest frame rates, but even Ultra maintains a playable 124 FPS at this resolution.

At 2560x1440, the results are: Low 154, Medium 133 (min 113, max 152), High 112, and Ultra 85. The Medium preset's min FPS of 113 is notably close to the High average of 112, suggesting that certain scenes at Medium can be as demanding as typical High scenarios. Ultra at 85 FPS is approaching the lower boundary of acceptable smoothness for fast-paced gameplay.

At 3840x2160, the measured averages are: Low 117, Medium 79 (min 67, max 90), High 66, and Ultra 50. The Medium preset shows a 23 FPS range, with the min of 67 being only 1 FPS above the High average. This indicates that 4K Medium can occasionally produce frame rates similar to 4K High, highlighting the unpredictability of Rust's rendering demands.

The overall FPS progression across resolutions and settings shows a consistent pattern: Low settings provide roughly 50-70% more FPS than Ultra at the same resolution. At 1080p, the gap is 175 vs 124 (41% difference); at 1440p, it's 154 vs 85 (81% difference); at 4K, it's 117 vs 50 (134% difference). The widening gap at higher resolutions confirms that the GPU is the limiting factor at 4K, while the CPU constrains performance at 1080p.

CPU Role

The Intel Core i5-11400F features 6 cores and 12 threads, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. This Rocket Lake architecture, built on Intel's 14 nm process, has a 12 MB shared L3 cache and 512 KB L2 cache per core. The CPU's 65 W TDP and DDR4 memory support suggest it is a mainstream part, not a high-end enthusiast chip.

In Rust, the CPU's role is most evident at 1080p with Low settings, where the combo achieves 175 FPS. This high frame rate likely approaches the CPU's limit for draw calls and game logic updates, as the GPU is not significantly stressed at these settings. The CPU's 3DMark single-thread score of 868 and Cinebench R23 single-core score of 2,024 indicate moderate single-thread performance, which is critical for Rust's simulation-heavy gameplay.

The CPU's multi-thread capabilities are stronger: Cinebench R23 multi-core score of 14,340 and 3DMark max-threads score of 5,652. These scores suggest that the 6-core/12-thread configuration can handle Rust's multi-threaded systems, but the game's performance is likely still limited by single-thread bottlenecks in certain scenarios.

The CPU's percentile of 71 places it slightly above average, with nearest rivals including the AMD EPYC 7H12 (0.3% higher), Intel Core i5-12450H (0.4% lower), and AMD Ryzen 3 PRO 8300G (0.6% lower). The tight margins among these CPUs indicate that the i5-11400F is in a competitive cluster where small architectural differences can shift rankings.

The data suggests that the CPU is not the primary bottleneck at 1440p and 4K, as the GPU's workload scales more significantly with resolution. However, at 1080p, the CPU's limitations prevent the RTX 4080 from reaching its full potential, as evidenced by the relatively small FPS gain from High (141) to Low (175) at 1080p compared to the larger gains at 1440p (112 to 154) and 4K (66 to 117). This indicates that the i5-11400F, while capable, leaves some GPU performance on the table at lower resolutions.
