Q: What is the frame rate difference between 1080p and 4K at High settings?

A: At 1920x1080 with High settings, the system achieves an average of 43 FPS. Increasing the resolution to 2560x1440 at the same High preset drops the average to 30 FPS, and at 3840x2160, the average falls to 18 FPS. This represents a 58% reduction in average frame rate from 1080p to 4K, highlighting the GPU's inability to handle higher pixel counts.

Q: Does the system show any signs of being CPU-limited in Rust?

A: The data suggests the system is heavily GPU-limited. For instance, at 2560x1440, lowering settings from High to Low increases the average FPS from 30 to 53, a substantial jump that indicates the graphics processor is the limiting factor. A CPU bottleneck would show less variation in frame rates across different graphical presets.

Q: What is the FPS range at Medium settings across different resolutions?

A: At 1920x1080 with Medium settings, the average FPS is 51, with a minimum of 44 and a maximum of 59. At 2560x1440, the average drops to 35 FPS, with a minimum of 30 and a maximum of 41. At 3840x2160, the average is 21 FPS, with a minimum of 18 and a maximum of 24.

Settings Recommendations

The benchmark data provides a clear verdict on the optimal settings for this hardware combination: the Low preset is the only setting that delivers a frame rate suitable for a playable experience in Rust. At 1920x1080, the Low preset achieves an average of 76 FPS, which is the only measured configuration to exceed the 60 FPS threshold. The Medium preset at the same resolution yields 51 FPS, which may be acceptable for some users but represents a 33% performance hit for improved visuals. The High and Ultra presets at 1080p, with averages of 43 FPS and 33 FPS respectively, are not recommended as they fall below the smoothness standard.

The performance scaling across presets confirms the GPU's dominance in limiting frame rates. At 1080p, moving from Low to Medium costs 25 FPS, and from Medium to High costs another 8 FPS. This steep drop-off suggests that the Arc B390's rendering capabilities are quickly overwhelmed by increased graphical complexity. The data indicates that users seeking a stable experience should prioritize frame rate over visual fidelity. Attempting to run Rust at higher settings will result in sub-60 FPS averages, which can be detrimental in a survival game where responsiveness is critical for player-vs-player interactions and environmental awareness.

For users who insist on higher visual quality, the Medium preset at 1080p offers a compromise, but the 51 FPS average and minimum of 44 FPS indicate it may still experience noticeable dips during intense scenes. The Ultra preset is entirely impractical, as it produces the lowest frame rates across all resolutions, including a 13 FPS average at 4K. The recommendation is to stick with Low at 1080p for the best balance of smoothness and playability, as the data shows no other preset combination provides a comparable experience.

Resolution Scaling

The measured FPS data reveals a pronounced and expected scaling pattern as resolution increases, which strongly indicates that the Intel Arc B390 is the primary limiting component in this system. At Low settings, the average frame rate drops from 76 FPS at 1920x1080 to 53 FPS at 2560x1440, a 30% reduction, and further to 31 FPS at 3840x2160, a 59% reduction from the 1080p baseline. This steep decline is characteristic of a GPU that lacks the raw pixel throughput required for higher resolutions. The pixel rate of 60.00 GPixel/s and 7.680 TFLOPS of FP32 performance are simply insufficient for the demands of 1440p and 4K rendering in Rust.

The scaling pattern is consistent across all settings presets. At High settings, the average FPS falls from 43 at 1080p to 30 at 1440p and 18 at 4K. The Ultra preset shows the most severe scaling, with averages of 33 FPS at 1080p, 23 FPS at 1440p, and 13 FPS at 4K. This consistent drop-off across all presets confirms that the bottleneck is the GPU's rendering capabilities rather than any other system component. If the CPU were the limiting factor, we would expect to see frame rates plateau at lower resolutions as the GPU becomes less stressed, but the data shows no such plateau; instead, every resolution increase results in a significant frame rate penalty.

The data suggests that the system is not viable for 1440p or 4K gaming in Rust, regardless of settings. Even at Low settings, the 4K average of 31 FPS is far below the playability threshold. The 1440p Low setting, with an average of 53 FPS, is borderline but likely to suffer from stutter and inconsistent frame pacing. The resolution scaling analysis leads to a single conclusion: this configuration is fundamentally a 1080p gaming setup for Rust, and any attempt to run it at higher resolutions will result in a degraded experience.

Measured FPS Breakdown

At 1920x1080, the system's performance is variable but offers one playable configuration. The Low preset delivers the highest average frame rate at 76 FPS, which is the only setting to clear the 60 FPS mark. The Medium preset averages 51 FPS, with a recorded minimum of 44 and maximum of 59 FPS, indicating some frame time variance. High settings bring the average down to 43 FPS, while the Ultra preset averages just 33 FPS, which is a 57% reduction from the Low preset's performance. The data shows a clear hierarchy at this resolution, with each step up in settings costing a significant number of frames.

Moving to 2560x1440, the performance drops across the board, reflecting the increased pixel load on the Arc B390. The Low preset averages 53 FPS, which is a substantial 30% decrease from its 1080p counterpart. Medium settings average 35 FPS, with a range of 30 to 41 FPS, while High settings average 30 FPS. The Ultra preset at 1440p averages 23 FPS, which is below the threshold for a smooth experience in a fast-paced survival game. The data indicates that 1440p is not a viable resolution for this system, as even the lowest settings fail to maintain a consistent 60 FPS.

At 3840x2160, the performance is largely unplayable. The Low preset averages 31 FPS, which is the best result at this resolution but still insufficient for smooth gameplay. Medium settings average 21 FPS, with a minimum of 18 and maximum of 24 FPS, while High settings average 18 FPS. The Ultra preset at 4K produces an average of just 13 FPS, which is the lowest measured frame rate across all configurations. This resolution is clearly beyond the capabilities of the Intel Arc B390, and the data shows no setting can bring the frame rate into a playable range.

GPU Role

The Intel Arc B390 is the decisive factor in this system's Rust performance, and the benchmark data shows it is a severe limiting component. With an average benchmark score of 1482, the GPU sits in the 9th percentile of all GPUs, placing it in the bottom tier of performance. Its nearest rivals are all legacy NVIDIA parts, with the GT 520MX scoring 1463, the GeForce 800M scoring 1460, and the GT 625 OEM scoring 1446. The B390's 1.3% lead over the GT 520MX is negligible, indicating that its real-world gaming performance is comparable to hardware from over a decade ago.

The GPU's specifications explain its poor showing in Rust. It features 1536 shading units, 48 TMUs, and 24 ROPs, with a boost clock of 2500 MHz and a base clock of 300 MHz. The texture rate is 120.0 GTexel/s, and the pixel rate is 60.00 GPixel/s. These figures are modest for a modern game like Rust, which features large, open-world environments with complex geometry and dynamic lighting. The GPU's memory configuration is "System Shared," meaning it relies on the system's main memory rather than dedicated VRAM, which can introduce latency and bandwidth bottlenecks in demanding scenarios.

The 7.680 TFLOPS of FP32 compute performance is insufficient for the game's rendering requirements at higher resolutions. The graph of measured FPS shows that the GPU's performance collapses as resolution increases, which is a classic sign of a hardware bottleneck. The boost clock of 2500 MHz is high, but the relatively low number of shaders and ROPs limits the amount of work that can be done per clock cycle. The data indicates that the Arc B390 is only suitable for low-resolution, low-detail gaming, and its performance in Rust is a direct reflection of its limited hardware resources.

CPU Role

The Intel Core i3-12100F plays a secondary but stable role in this system's Rust performance, with benchmark data showing it is more than capable of feeding the GPU in most scenarios. The CPU scores in the 68th percentile of all processors, with an average benchmark score of 13494, placing it in the mid-range of desktop CPUs. Its nearest rivals are closely matched, with the Intel Core 3 N355 having a score of 13492 and the Intel Core i5-9500 having a score of 13452, showing that the i3-12100F offers competitive performance in its class.

The CPU's specifications are solid for a quad-core part. It has 4 cores and 8 threads, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. The Alder Lake architecture and 10 nm process node contribute to its efficiency. The cache hierarchy includes 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and a shared 12 MB L3 cache. The CPU's benchmark results show strong single-threaded performance, with a 3dmark single-thread score of 893 and a Cinebench R23 single-core score of 1674, which is important for Rust's game logic and physics calculations.

The data suggests that the CPU is not the primary bottleneck in this configuration. Evidence for this is found in the FPS scaling across settings at a fixed resolution. At 1080p, the average FPS ranges from 33 at Ultra to 76 at Low, a dramatic shift that indicates the GPU is the limiting factor. If the CPU were the bottleneck, the frame rates would remain more consistent across different settings. The i3-12100F's multi-threaded scores, such as 11860 in Cinebench R23 multi-core and 14015 in Passmark multithread, show it has sufficient processing power to handle the game's background tasks. The data implies that while the CPU is not the star of the show, it is performing its role without holding back the GPU, making the Arc B390 the clear target for any future upgrade.
