Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The data shows a steep and consistent FPS penalty as resolution climbs, but the shape of that curve reveals a system that transitions from CPU-leaning at 1080p to firmly GPU-bound at 4K. At 1920x1080 with Low settings, the combo produces 271 FPS average; at 2560x1440 Low, that drops to 187 FPS, and at 3840x2160 Low it falls to 110 FPS. That represents a 31% reduction from 1080p to 1440p and a further 41% reduction from 1440p to 4K. The scaling is nearly linear in pixel count, which is a classic signature of GPU limitation at the higher resolutions.

However, at Ultra settings the scaling behaves differently. The 1080p Ultra average is 117 FPS, 1440p Ultra is 80 FPS, and 4K Ultra is 47 FPS. The drop from 1080p to 1440p is 31.6%, and from 1440p to 4K it's 41.3%. The percentage losses are almost identical across Low and Ultra presets, indicating that the GPU is the primary bottleneck throughout the resolution range, regardless of settings. The Intel Core Ultra 7 270K Plus, with its 24 cores and 24 threads, is clearly not the limiting factor at any resolution tested.

The Medium preset, which is the only setting with min and max FPS recorded at all three resolutions, shows the same pattern. At 1080p Medium, the average is 182 FPS with a minimum of 155 FPS and a maximum of 209 FPS. At 1440p Medium, the average drops to 125 FPS with a minimum of 106 FPS and a maximum of 144 FPS. At 4K Medium, the average is 74 FPS with a minimum of 63 FPS and a maximum of 85 FPS. The minimum FPS values track proportionally with the averages, suggesting consistent frame pacing rather than isolated stutters.

The High preset fills in the middle of the curve. At 1080p High, the average is 154 FPS; at 1440p High, it's 106 FPS; and at 4K High, it's 62 FPS. The High preset at 1440p delivers essentially the same average as the Ultra preset at 1080p (106 vs. 117 FPS), which is a useful reference point for players deciding between resolution and quality. The delta between Low and Ultra at each resolution is substantial: 154 FPS at 1080p (271 vs. 117), 107 FPS at 1440p (187 vs. 80), and 63 FPS at 4K (110 vs. 47). This spread indicates that Rust's settings have a major impact on GPU load.

The fact that 4K Ultra only achieves 47 FPS average puts this combo below the 60 FPS threshold for smooth gameplay at maximum quality. But 4K High at 62 FPS clears that bar, and 4K Medium at 74 FPS provides more headroom. The 4K Low result of 110 FPS shows that even at maximum resolution, the RTX 5070 Ti has substantial performance reserves when graphical fidelity is reduced.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5070 Ti carries 16 GB of GDDR7 memory on a 256-bit bus, yielding 896.0 GB/s of bandwidth. That configuration is more than sufficient for Rust at any of the tested settings, as evidenced by the consistent frame pacing in the Medium preset's min FPS values. The memory clocks run at 1750 MHz with 28 Gbps effective transfer, and the GPU's base clock is 2295 MHz with a boost clock of 2452 MHz. The boost behavior matters here because Rust's open-world rendering can sustain high GPU utilization, allowing the card to operate near its boost ceiling.

The GPU's 8960 shading units and 280 texture mapping units provide the raw compute needed for Rust's terrain and building rendering. The 96 ROPs handle pixel output, and at 4K Ultra the card still manages 47 FPS, which is a demanding pixel rate of over 8 million pixels per frame. The pixel rate of 235.4 GPixel/s and texture rate of 686.6 GTexel/s are benchmark-verified specs that align with the measured FPS results. When the settings drop to Low, the reduced shading and texture work allows the card to nearly triple its 4K frame rate.

The RTX 5070 Ti's 70 RT cores and 280 tensor cores contribute to features that Rust can leverage, though the measured results do not isolate ray tracing or DLSS performance. The GPU's FP32 throughput of 43.94 TFLOPS is the same as its FP16 throughput at a 1:1 ratio, indicating strong compute capability. The card's 300 W TDP and dual-slot design with a 1x 16-pin power connector are consistent with a high-end enthusiast tier, and the PCIe 5.0 x16 interface ensures no bandwidth limitation.

The GPU's benchmark profile shows a 3DMark Steel Nomad DX12 score of 6604, a Geekbench OpenCL score of 212363, and a Geekbench Vulkan score of 225122. The Passmark G3D score is 32974 with a GPU compute score of 20203. These synthetic results place the RTX 5070 Ti in the 86th percentile of all GPUs, and its nearest rivals in the database include the AMD Radeon RX Vega 64 (deltaPct -0.1), the Intel Arc A550M (deltaPct 0.4), the AMD Radeon RX 6900 XT (deltaPct -2), and the AMD Radeon RX 6800 XT (deltaPct 3.1). The RTX 5070 Ti's average benchmark score of 49957 is nearly identical to the RX Vega 64's 50001, despite the massive generational gap in architecture.

In Rust specifically, the measured FPS data indicates that the GPU is the deciding factor at 1440p and 4K, while the CPU's strong single-thread and multi-thread performance prevents it from becoming a bottleneck even at 1080p Low where 271 FPS is achieved. The Intel Core Ultra 7 270K Plus has a Cinebench R23 single-core score of 2439 and a multi-core score of 44253, with a Passmark single-thread score of 5068. These numbers confirm that the CPU can feed the GPU fast enough to reach high frame rates.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the full settings sweep shows a wide performance envelope. The Low preset delivers the highest average at 271 FPS. The Medium preset averages 182 FPS with a minimum of 155 FPS and a maximum of 209 FPS. The High preset averages 154 FPS. The Ultra preset averages 117 FPS. The progression from Low to Ultra is 271, 182, 154, and 117 FPS respectively, with each step up in quality costing a significant number of frames. The gap between Medium and High is 28 FPS, while the gap between High and Ultra is 37 FPS. The Medium preset's minimum of 155 FPS is still higher than the Ultra preset's average of 117 FPS, which underscores how much of a performance hit the Ultra settings impose.

At 2560x1440, the same pattern emerges with lower absolute numbers. The Low preset averages 187 FPS. The Medium preset averages 125 FPS with a minimum of 106 FPS and a maximum of 144 FPS. The High preset averages 106 FPS. The Ultra preset averages 80 FPS. The step from Low to Medium is 62 FPS, from Medium to High is 19 FPS, and from High to Ultra is 26 FPS. Notably, the 1440p High average of 106 FPS exactly matches the 1440p Medium minimum of 106 FPS, which means that even at Medium settings, frame drops can reach the High preset's average. The 1440p Medium maximum of 144 FPS is 14 FPS higher than the 1080p Ultra average of 117 FPS, showing that resolution scaling is not uniform across settings.

At 3840x2160, the results show the GPU working hardest. The Low preset averages 110 FPS. The Medium preset averages 74 FPS with a minimum of 63 FPS and a maximum of 85 FPS. The High preset averages 62 FPS. The Ultra preset averages 47 FPS. The 4K Medium minimum of 63 FPS is just above the 60 FPS threshold, while the 4K High average of 62 FPS leaves only 2 FPS of headroom. The 4K Ultra average of 47 FPS is the only measured result that falls firmly below playable frame rates. The spread from Low to Ultra at 4K is 63 FPS, which is the smallest absolute spread across all resolutions, but the percentage delta is consistent with the other resolutions.

The Medium preset is the only settings level where min and max FPS are recorded at every resolution, providing the most complete picture of frame time consistency. At 1080p, the Medium range is 54 FPS (155 to 209). At 1440p, the range is 38 FPS (106 to 144). At 4K, the range is 22 FPS (63 to 85). The narrowing range at higher resolutions indicates that the GPU's frame production becomes more consistent as it approaches its limit, which is typical behavior for a GPU-bound scenario.

The result is a combo that performs in the top percentile of all tested configurations, with only 198 combos delivering higher FPS in this specific game.

Settings Recommendations — which preset gives the best experience per the measured rows

The data supports different recommendations depending on the target resolution, but the Medium preset emerges as the most balanced choice across all three resolutions. At 1080p Medium, the combo averages 182 FPS with a minimum of 155 FPS, which is far above any competitive threshold. The High preset at 1080p still averages 154 FPS, and even Ultra at 117 FPS is playable. For 1080p users, the Ultra preset at 117 FPS is the best visual experience while maintaining high frame rates, and the Low preset at 271 FPS is available for competitive play where maximum frame rate is prioritized.

At 1440p, the Medium preset averages 125 FPS with a minimum of 106 FPS, which is an excellent balance of visual quality and performance. The High preset at 106 FPS is nearly identical to the Medium minimum, meaning that High settings will occasionally dip below the Medium average. The Ultra preset at 80 FPS is still above 60 FPS and provides the best image quality, but the Medium preset's 19 FPS advantage over High and 45 FPS advantage over Ultra make it the safer choice for consistent frame delivery. The 1440p Low preset at 187 FPS is the best option for high-refresh-rate monitors, but it sacrifices significant visual fidelity.

At 4K, the Medium preset at 74 FPS is the clear recommendation. It provides a 12 FPS advantage over High (62 FPS) and a 27 FPS advantage over Ultra (47 FPS), while maintaining a minimum of 63 FPS that stays above the 60 FPS threshold. The 4K High preset at 62 FPS is playable but leaves little margin for frame drops, and the 4K Ultra preset at 47 FPS is not recommended for smooth gameplay. The 4K Low preset at 110 FPS is the fastest option but may not take full advantage of the 16 GB VRAM and high-end GPU.

The measured data shows that the Medium preset offers the most consistent frame delivery, as evidenced by the recorded min and max FPS values at all three resolutions. The gap between minimum and maximum FPS is 54 FPS at 1080p, 38 FPS at 1440p, and 22 FPS at 4K, which indicates that frame pacing becomes more stable as resolution increases. For players who prioritize a smooth experience over maximum visual fidelity, the Medium preset is the best choice at 1440p and 4K, while the Ultra preset is viable at 1080p. The High preset is a middle ground that works well at 1080p and 1440p but is marginal at 4K. The Low preset is only recommended for competitive play at 1080p or 1440p where maximum FPS is the primary goal.
