Q: Is there a measurable FPS difference between Low and Ultra at 4K?

A: Yes, the gap is substantial. Low averages 28 FPS at 3840x2160, while Ultra averages 12 FPS. That is a 16 FPS difference, representing a 57 percent drop from the lowest preset to the highest preset.

Settings Recommendations

The measured data for Rust with this hardware paints a clear picture: only the Low preset provides a consistently playable experience, and even then, only at 1080p. At 1920x1080, Low delivers 69 FPS average, which is the sole configuration in the entire dataset to exceed 60 FPS. Medium at the same resolution drops to 46 FPS, which remains technically playable but introduces noticeable compromises in smoothness. High drops further to 39 FPS, and Ultra bottoms out at 30 FPS.

The pattern repeats at 1440p with lower absolute numbers. Low produces 48 FPS, Medium 32 FPS, High 27 FPS, and Ultra 20 FPS. At 4K, the situation becomes marginal across the board: Low averages 28 FPS, Medium 19 FPS, High 16 FPS, and Ultra 12 FPS. The Medium preset at 4K has a recorded min FPS of 16 and max FPS of 22, showing tight frame pacing but at an unplayable level.

Given these measurements, the recommended preset is Low at 1080p. It is the only configuration where the average FPS clears the 60 FPS bar, and it does so with a 21 FPS margin over the next best option (Medium at 1080p). Players who prioritize visual fidelity over frame rate could consider Medium at 1080p, which offers a 46 FPS average, but the data suggests this is a compromise that sacrifices smoothness without achieving a locked 60. At higher resolutions, no preset reaches even 50 FPS, so the practical ceiling for this combo is 1080p with Low settings.

The Ultra preset is not recommended at any resolution. Its best showing is 30 FPS at 1080p, and at 4K it falls to 12 FPS. The performance cost of Ultra over High is consistent: roughly 23 percent at 1080p, 26 percent at 1440p, and 25 percent at 4K. The visual return on that investment is not quantifiable from the data, but the frame rate penalty is severe enough that the preset should be avoided for any gameplay scenario.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a system that is heavily GPU-limited at every resolution. At Low settings, the transition from 1920x1080 to 2560x1440 reduces the average from 69 to 48 FPS, a 30 percent decrease. Moving from 1440p to 4K drops the average from 48 to 28 FPS, another 42 percent reduction. The cumulative effect from 1080p to 4K at Low is a 59 percent loss in frame rate, from 69 to 28 FPS.

The scaling pattern holds across all presets. At Medium, 1080p yields 46 FPS, 1440p yields 32 FPS, and 4K yields 19 FPS. That is a 59 percent total drop from 1080p to 4K, nearly identical to the Low preset's scaling. At High, the numbers are 39 FPS at 1080p, 27 FPS at 1440p, and 16 FPS at 4K, a 59 percent reduction. Ultra follows the same trajectory: 30 FPS at 1080p, 20 FPS at 1440p, and 12 FPS at 4K, a 60 percent drop.

The consistency of this 59-60 percent scaling across all four presets is significant. It indicates that the GPU is the bottleneck at every resolution and every quality level. If the CPU were the limiting factor, the FPS would scale less severely with resolution, because the CPU workload remains roughly constant while the GPU workload increases with pixel count. Instead, the nearly uniform percentage drops suggest that the Intel Arc B370's rendering throughput is the dominant constraint.

The 1080p to 1440p transition costs 30 percent of performance, while the 1440p to 4K transition costs 41-42 percent. This is a steeper than linear scaling, which aligns with the pixel count increases: 1440p has 1.78 times the pixels of 1080p, and 4K has 2.25 times the pixels of 1440p. The GPU cannot maintain frame rates as pixel count grows, confirming that the Arc B370's 6.144 TFLOPS FP32 throughput is inadequate for higher resolutions in Rust.

Measured FPS Breakdown

At 1920x1080, the measured results span a wide range depending on settings. Low averages 69 FPS, which is the highest figure in the entire dataset. Medium averages 46 FPS with a recorded range of 39 to 53 FPS. High averages 39 FPS. Ultra averages 30 FPS. The spread from Low to Ultra is 39 FPS, meaning Ultra delivers only 43 percent of the frame rate achievable on Low.

At 2560x1440, all averages shift downward by roughly 30 percent. Low averages 48 FPS. Medium averages 32 FPS with a range of 27 to 37 FPS. High averages 27 FPS. Ultra averages 20 FPS. The difference between Low and Ultra at this resolution is 28 FPS, with Ultra providing 42 percent of Low's performance.

At 3840x2160, the numbers become marginal. Low averages 28 FPS. Medium averages 19 FPS with a range of 16 to 22 FPS. High averages 16 FPS. Ultra averages 12 FPS. The Low to Ultra gap narrows to 16 FPS, but the relative ratio remains consistent: Ultra produces 43 percent of Low's average FPS.

The Medium preset is the only one with recorded min and max FPS values across all three resolutions. At 1080p, the range is 39 to 53 FPS around a 46 FPS average, indicating a 14 FPS variance. At 1440p, the range is 27 to 37 FPS around a 32 FPS average, a 10 FPS variance. At 4K, the range is 16 to 22 FPS around a 19 FPS average, a 6 FPS variance. The narrowing range at higher resolutions suggests that frame pacing becomes more consistent as the GPU becomes more saturated, though the absolute frame rates are too low for playability at 4K.

The data shows that Low at 1080p is the only configuration that exceeds 60 FPS, and Low at 1440p is the only other configuration that exceeds 45 FPS. Every other combination falls below 46 FPS, and most fall below 40 FPS. The Ultra preset never exceeds 30 FPS at any resolution, capping at exactly 30 FPS at 1080p.

GPU Role

The Intel Arc B370 is the primary performance limiter in this combination. Its benchmark score of 1184 in 3DMark Steel Nomad DX12 places it at the 5th percentile among all GPUs, and its nearest rivals are all legacy parts: the ATI Mobility Radeon HD 5570 (0.2 percent faster), ATI Radeon HD 5770 (0.5 percent faster), AMD Radeon HD 7650M (0.7 percent faster), and AMD FirePro M2000 (1.4 percent slower). This is a GPU that competes with hardware from over a decade ago.

The GPU's architecture is Xe3-LPG on a 3 nm process from Intel, with 1280 shading units, 40 texture mapping units, and 20 raster output pipelines. It has 10 ray tracing cores. The clock speeds range from a 300 MHz base to a 2400 MHz boost, which is a wide frequency spread indicating aggressive boosting behavior. The pixel rate is 48.00 GPixel/s and the texture rate is 96.00 GTexel/s. FP32 performance is 6.144 TFLOPS.

Critically, the memory subsystem is System Shared. The GPU has no dedicated VRAM; it uses the system's main memory, with bandwidth listed as System Dependent. This means the memory performance scales with the CPU's memory configuration, which in this case is dual-channel DDR5 with 102.4 GB/s bandwidth on the CPU side. The GPU's effective memory bandwidth is therefore constrained by the same memory bus that serves the CPU, creating potential contention.

The 25 W TDP and IGP form factor further confirm that this is not a discrete-class part. The GPU is integrated into the processor package, sharing thermal and power budgets with the CPU. Despite its low power draw, the Arc B370's rendering throughput is the bottleneck in Rust at every resolution and preset, as evidenced by the uniform 59-60 percent FPS scaling from 1080p to 4K.

The measured FPS data corroborates the benchmark score. At 1080p Low, the GPU manages 69 FPS, which is nearly 2.5 times the 28 FPS it achieves at 4K Low. The GPU's texture rate of 96.00 GTexel/s and pixel rate of 48.00 GPixel/s are simply insufficient for the pixel throughput demanded by 4K in Rust, particularly with higher quality settings that increase overdraw and texture sampling.

CPU Role

The Intel Core Ultra 7 265K is a far more capable component than the GPU, and its benchmark results place it near the top of the desktop CPU hierarchy. It sits at the 94th percentile among all CPUs, with an average benchmark score of 70,879. Its nearest rivals are the Intel Xeon 6511P (0.2 percent faster), Intel Xeon Platinum 8270 (0.7 percent faster), Intel Core i7-14700KF (1 percent slower), and AMD Ryzen 7 9700F (1.3 percent slower). The CPU is competitive with or slightly ahead of these alternatives.

The CPU's specifications are substantial. It has 20 cores and 20 threads, running at a 3.90 GHz base clock and 5.50 GHz boost clock. The Arrow Lake-S architecture uses a 3 nm process from TSMC with 17,800 million transistors on a 243 mm² die. Cache is configured as 192 KB L1 per core, 3 MB L2 per core, and 30 MB shared L3. Memory support is dual-channel DDR5 with 102.4 GB/s bandwidth, and ECC memory is supported.

In synthetic benchmarks, the CPU shows strong multi-threaded and single-threaded performance. Cinebench R23 scores are 35,850 multi-core and 2,020 single-core. Geekbench scores are 23,085 multi-core and 2,713 single-core. PassMark results are also robust: 58,594 multithread, 4,928 single-thread, 143,242 integer math, 189,629 floating point math, and 665,554 data compression. These figures indicate a CPU that is far from being the limiting factor in Rust.

The measured FPS data confirms that the CPU is not the bottleneck. If the CPU were the constraint, the frame rates would be similar across resolutions, because the CPU workload in Rust (physics, entity updates, server-side simulation) does not scale with pixel count. Instead, the FPS drops dramatically with resolution, falling from 69 FPS at 1080p Low to 28 FPS at 4K Low. This resolution-dependent scaling is the signature of a GPU-limited configuration.

The CPU's 20 cores and 20 threads provide ample headroom for Rust's simulation and rendering threads. The 125 W TDP and unlocked multiplier allow for further tuning, though the data does not include overclocking results. The CPU's 94th percentile ranking and its narrow margins against the Xeon 6511P and Xeon Platinum 8270 indicate that it is punching at or above its weight class, but the Arc B370's 5th percentile GPU ranking drags the overall combo down to the 2710th position out of 2953 combinations.

The Core Ultra 7 265K's integrated graphics, the Arc Xe-LPG Graphics 64EU, is separate from the Arc B370 GPU. The B370 is a different part, with 1280 shading units and a 2400 MHz boost clock, whereas the CPU's IGP has 64 execution units. The presence of the B370 as a discrete-class IGP (25 W TDP, no power connectors) means the system is using the B370 for rendering in these Rust benchmarks, not the CPU's built-in graphics. The CPU's role is to feed the GPU with draw calls and simulation data, and its robust single-threaded score of 2,020 in Cinebench R23 ensures it does so without introducing frame pacing issues.
