Rust

The Intel Core i5-11400F paired with the Intel Arc B390 is a combination that delivers playable performance in Rust only at 1080p with the lowest settings. At higher resolutions or with more demanding presets, the system falls below the 60 FPS threshold, making those configurations unsuitable for smooth gameplay. The data indicates a clear hardware bottleneck, primarily driven by the GPU, which ranks in the bottom percentile of all tested graphics cards.

Best Settings per Resolution

At 1920x1080, the only preset that maintains an average frame rate at or above 60 FPS is Low, which delivers 76 FPS on average. This is the sole configuration across all tested resolutions that meets the playability threshold. The next step up, Medium, drops to 51 FPS, which is below the 60 FPS target, so it cannot be recommended for a consistent experience. High settings at this resolution yield 43 FPS, and Ultra falls to 33 FPS.

For 2560x1440, no settings preset reaches 60 FPS. The best option is Low, averaging 53 FPS, which is close but still short of the target. Medium produces 35 FPS, High produces 30 FPS, and Ultra produces 23 FPS. At 3840x2160, the situation is more severe: Low averages 31 FPS, Medium averages 21 FPS, High averages 18 FPS, and Ultra averages 13 FPS. None of these are viable for 60 FPS gameplay.

Similar Performance Alternatives

The recorded benchmarks place the Intel Arc B390 near the bottom of the GPU performance spectrum. Its nearest rivals, based on averaged benchmark scores, include the NVIDIA GeForce GT 520MX, which scores 1.3% higher, and the NVIDIA GeForce 800M, which scores 1.5% higher. The NVIDIA GeForce GT 625 OEM and the GT 710 are also close, scoring 2.5% and 2.7% higher, respectively. These differences are minimal, meaning any of these GPUs would produce nearly identical frame rates in Rust. Users with any of these cards should expect the same inability to exceed 60 FPS at 1080p with Medium or higher settings.

On the CPU side, the Intel Core i5-11400F sits near the 71st percentile of all tested processors. Its nearest rivals include the AMD EPYC 7H12, which scores 0.3% higher, and the Intel Core i5-12450H, which scores 0.4% lower. The AMD Ryzen 3 PRO 8300G is 0.6% lower, and the Intel Core Ultra 7 164U is 0.6% higher. These CPU differences are negligible in gaming scenarios, so swapping between these processors would not meaningfully change the frame rates recorded for this combo. The system’s performance is entirely constrained by the GPU.

Measured FPS Breakdown

At 1920x1080, the recorded data shows a steady progression of frame rates across presets. Low averages 76 FPS, which is the only result above 60. Medium averages 51 FPS, with a minimum of 44 and a maximum of 59. High averages 43 FPS, and Ultra averages 33 FPS. The gap between Low and Medium is 25 FPS, indicating a significant performance cost for the next visual step up. The minimum and maximum values for Medium show a narrow range, from 44 to 59, which suggests consistent frame times at that preset, though still below the target.

At 2560x1440, the frame rates drop substantially. Low averages 53 FPS, which is 23 FPS lower than at 1080p. Medium averages 35 FPS, with a minimum of 30 and a maximum of 41. High averages 30 FPS, and Ultra averages 23 FPS. The step from 1080p to 1440p costs roughly 23 FPS at Low and 16 FPS at Medium, showing the resolution scaling penalty. The Medium preset’s minimum of 30 FPS is half the target frame rate, which would result in noticeable stutter during complex scenes.

At 3840x2160, the results are the lowest across the board. Low averages 31 FPS, which is less than half of the 60 FPS target. Medium averages 21 FPS, with a minimum of 18 and a maximum of 24. High averages 18 FPS, and Ultra averages 13 FPS. The data shows that this resolution is not suitable for any preset, as even the lowest graphics settings produce frame rates that are too low for a responsive experience. The range for Medium, from 18 to 24 FPS, shows that the system is under heavy load and cannot sustain a stable frame rate.

The Verdict

Based on the recorded data, this PC can run Rust, but only under strict conditions. At 1920x1080, the Low preset achieves an average of 76 FPS, which clears the 60 FPS threshold. This is the single playable configuration. The verdict by resolution confirms that 1080p with Low is the only viable path. At 2560x1440, all presets fall below 60 FPS, with the best case being Low at 53 FPS. At 3840x2160, even the lowest preset fails to reach 60 FPS, averaging 31 FPS. Therefore, users must accept 1080p Low for a playable experience. Any attempt to raise settings to Medium or above at 1080p results in frame rates between 33 and 51 FPS, which are not smooth enough for a survival game where reaction time matters. The system is not capable of delivering playable performance at higher resolutions, and the hardware’s bottleneck is the graphics card.

FAQ

Q: Can this PC run Rust at 1080p?

A: Yes, at 1080p with the Low preset, it averages 76 FPS, which is above the 60 FPS playable threshold. Medium, High, and Ultra all fall below 60 FPS.

Q: What is the best preset for 1440p?

A: No preset at 2560x1440 is playable. The lowest preset averages 53 FPS, which is below the 60 FPS target.

Q: Is 4K gaming possible with this combo?

A: No. At 3840x2160, even the Low preset averages only 31 FPS, which is far below the playable threshold.

Q: How does the GPU compare to its nearest rivals?

A: The Arc B390 is closely matched with the NVIDIA GeForce GT 520MX, which is 1.3% faster in benchmarks. The NVIDIA GeForce 800M is 1.5% faster, and the GT 625 OEM is 2.5% faster.

Q: What frame rate does Medium settings produce at 1080p?

A: Medium settings at 1920x1080 average 51 FPS, with a minimum of 44 and a maximum of 59. This is below the 60 FPS threshold.

Q: Is the CPU a limiting factor?

A: No. The CPU’s nearest rivals are within 0.6% of its score, meaning it is not the bottleneck. The GPU’s performance is the determining factor for frame rates.

How This Combo Ranks

In the database’s list of tested combos for Rust, this pairing is ranked 3312 out of 3723 systems. This places it in the lower 11% of results, confirming the weak performance observed in the frame rate data. The rank reflects the combined capability of the CPU and GPU, with the GPU’s low benchmark score dragging the overall position down. In practical terms, it shows that the majority of tested combos can achieve higher frame rates at more demanding settings. The data indicates that the Intel Core i5-11400F is not the issue, as it ranks in the 71st percentile for CPUs. The Arc B390, however, ranks in the 9th percentile for GPUs, making it the clear source of the low performance. Users with this combination should consider it a low-end solution that is only suitable for 1080p gaming at the absolute minimum settings, and even then it barely clears the 60 FPS bar. The large gap between this combo’s rank and the top performers underscores the need for a more powerful GPU to unlock higher presets and resolutions in Rust.
