Rust

Rust, with the Intel Core i5-14600K and NVIDIA GeForce RTX 5090 D, demonstrates a clear GPU-bound progression as resolution climbs, though the CPU's strong single-core performance keeps 1080p and 1440p framerates exceptionally high. The data shows that at 1920x1080, the combination delivers an average of 250 FPS on Low settings, which drops to 197 FPS on High and 150 FPS on Ultra. This scaling pattern, where the gap between Low and Ultra is 100 FPS at 1080p, narrows to 80 FPS at 2560x1440 (221 vs 103) and further to 80 FPS at 3840x2160 (141 vs 61), indicates that the RTX 5090 D's massive compute capacity is being progressively taxed by pixel count, while the i5-14600K's 5.30 GHz boost clock ensures it never becomes the primary limiter even at lower resolutions.

The transition from 1080p to 1440p sees an average FPS drop of approximately 21-24% across settings, while moving from 1440p to 4K yields a steeper 41-42% reduction. This non-linear decline is typical for a GPU with 32 GB of GDDR7 memory and 104.8 TFLOPS FP32 performance, as Rust's draw calls and object density at 4K begin to saturate the rendering pipeline. At 3840x2160 Medium, the combo maintains 95 FPS with a minimum of 81 FPS, suggesting that even demanding scenes stay well above playable thresholds. The Ultra preset at 4K drops to 61 FPS, which is still smooth for a survival game but represents the first setting where framerate dips below the 80 FPS mark seen at High, confirming that the GPU is the dominant constraint at this resolution.

Resolution Scaling

The measured FPS data reveals that the RTX 5090 D's performance scales predictably with resolution, but the rate of decline is steeper than typical for high-end GPUs due to Rust's engine overhead. From 1920x1080 to 2560x1440, the average FPS drops by 41 FPS on High (197 to 136) and 79 FPS on Low (250 to 221), representing a 21% and 12% reduction respectively. The relatively smaller percentage drop on Low suggests that at 1080p Low, the CPU's 14 cores and 20 threads are beginning to influence performance, as the GPU has ample headroom to render frames faster than the game logic can feed it.

Moving from 2560x1440 to 3840x2160, the reductions become more uniform across settings: High falls from 136 to 80 FPS (41% drop), Medium from 161 to 95 FPS (41% drop), and Low from 221 to 141 FPS (36% drop). This consistency indicates that at 4K, the GPU's shading units and memory bandwidth (1.79 TB/s) are the limiting factors, with the i5-14600K's 24 MB shared L3 cache and 3.50 GHz base clock providing sufficient data throughput. The Ultra preset at 4K, at 61 FPS, is 24% slower than High, which reflects the exponential cost of maximum draw distances and anti-aliasing in Rust's open-world environments.

The data also shows that the gap between Low and Medium settings narrows as resolution increases. At 1080p, the difference is 35 FPS (250 vs 215), at 1440p it is 60 FPS (221 vs 161), and at 4K it is 46 FPS (141 vs 95). This pattern suggests that Medium settings introduce GPU-intensive effects that become more expensive at higher pixel counts, while Low settings at 4K still allow the RTX 5090 D to push 141 FPS, which is remarkable for a game known for its server-side physics and player-built structures.

Measured FPS Breakdown

At 1920x1080, the combo delivers a full range of framerates across all presets. Low settings produce an average of 250 FPS, which is the highest measured value in the entire dataset. Medium settings average 215 FPS with a minimum of 183 FPS and maximum of 247 FPS, showing tight frame pacing. High settings drop to 197 FPS, while Ultra averages 150 FPS. The 100 FPS spread between Low and Ultra at 1080p demonstrates that the RTX 5090 D's 104.8 TFLOPS of compute power is only partially utilized at this resolution, with CPU-bound scenarios likely capping performance at the highest framerates.

At 2560x1440, the performance scales down predictably. Low settings average 221 FPS, which is still exceptionally high for a survival game. Medium settings average 161 FPS with a minimum of 136 FPS and maximum of 185 FPS, representing the best balance of smoothness and visual fidelity. High settings average 136 FPS, while Ultra drops to 103 FPS. The 118 FPS difference between Low and Ultra at 1440p indicates that the GPU is now more engaged, but the i5-14600K's performance remains sufficient to avoid major bottlenecks.

At 3840x2160, the RTX 5090 D's 32 GB of GDDR7 memory and 512-bit bus width become critical. Low settings still achieve 141 FPS, which is impressive for 4K. Medium settings average 95 FPS with a minimum of 81 FPS, making it the most stable preset at this resolution. High settings average 80 FPS, while Ultra drops to 61 FPS. The 80 FPS gap between Low and Ultra at 4K is the smallest of any resolution, confirming that the GPU is the primary constraint and that the CPU has ample headroom to support even the most demanding graphical settings.

Settings Recommendations

For players prioritizing competitive performance, the Low preset at 2560x1440 (221 FPS) or 1920x1080 (250 FPS) offers the highest framerates, though the data shows diminishing returns beyond 200 FPS for most displays. The Medium preset is the best all-rounder: at 2560x1440 it provides 161 FPS average with a minimum of 136 FPS, which is 25 FPS faster than High and 58 FPS faster than Ultra while maintaining visual clarity. The min/max data for Medium (136-185 at 1440p, 183-247 at 1080p) indicates stable frame pacing, which is crucial for Rust's PvP encounters where sudden frame drops can be fatal.

At 4K, the Medium preset (95 FPS, min 81 FPS) is the recommended choice for a smooth experience, as it stays above the 80 FPS threshold that High barely meets. The Ultra preset at 61 FPS is playable but risks dropping below 60 FPS in dense player-built bases or during large raid battles. For players with high-refresh-rate 4K monitors, the High preset at 80 FPS offers a better balance than Ultra, with only a 15 FPS cost over Medium but significantly better shadows and draw distances. The data suggests that Medium at any resolution provides the most consistent experience, as it is the only preset with measured minimum FPS values across all three resolutions, indicating better frame-time stability.

The 1080p Medium preset (215 FPS, min 183 FPS) is overkill for most displays but ensures no drops below 180 FPS, making it ideal for esports-style play on 240Hz monitors. For 1440p users, Medium at 161 FPS (min 136 FPS) is the sweet spot, offering 25 FPS more than High and 58 FPS more than Ultra with minimal visual compromise. The data does not show any advantage to using Low at 1080p beyond the 250 FPS average, which exceeds the refresh rate of virtually all consumer monitors.

CPU Role

The Intel Core i5-14600K, with its 14 cores (likely a mix of performance and efficiency cores) and 20 threads, plays a critical role in Rust's performance. The CPU's 5.30 GHz boost clock and 24 MB shared L3 cache are essential for handling the game's server-side simulation, which includes player positions, building destruction, and environmental changes. The Passmark single-thread score of 4270 and Cinebench R23 single-core score of 2064 indicate strong per-core performance, which is more important than raw multi-core throughput for Rust's game logic threaded across several main threads.

The CPU's multi-core capabilities, evidenced by a Cinebench R23 multicore score of 24491 and Passmark multithread score of 38682, ensure that background tasks like asset streaming and physics calculations do not interfere with the main render thread. The 125W TDP and Intel Socket 1700 platform provide sufficient power delivery for sustained boosts, which is crucial during long gaming sessions. The i5-14600K's 90th percentile ranking among all CPUs, with nearest rivals like the Intel Xeon Gold 5318H (0.2% lower) and AMD EPYC 4345P (0.3% higher), shows that it competes with server-grade parts in synthetic benchmarks while offering better gaming-specific optimizations.

The data shows that the CPU's influence is most pronounced at 1080p Low, where the 250 FPS average likely approaches the engine's internal frame rate cap or the CPU's ability to process game ticks. At higher resolutions, the GPU takes over as the primary bottleneck, but the i5-14600K's consistent performance ensures that it never causes framerate drops below the GPU's output. The 3.50 GHz base clock and 5.30 GHz boost clock provide a wide dynamic range, allowing the CPU to idle efficiently during less demanding scenes and ramp up during large-scale raids. The 10 nm process node and Raptor Lake architecture deliver the single-thread performance that Rust's Unreal Engine-derived codebase requires, making this CPU an ideal match for the RTX 5090 D in this title.
