# Resolution Scaling

The measured FPS data for Rust with the AMD Ryzen 7 7700 and NVIDIA GeForce RTX 4080 reveals a clear pattern of how performance scales across the three tested resolutions. At 1080p with Low settings, the combo produces 238 FPS, which drops to 198 FPS at 1440p and 117 FPS at 4K. That represents a 17% reduction from 1080p to 1440p, and a further 41% reduction from 1440p to 4K. The scaling is substantial, indicating that higher resolutions place progressively heavier demands on the GPU.

Looking at High settings, the pattern continues but with slightly different proportions. The combo achieves 163 FPS at 1080p, 112 FPS at 1440p, and 66 FPS at 4K. The drop from 1440p to 4K is 41%, nearly identical to the Low settings drop. However, the drop from 1080p to 1440p is 31% at High settings, notably steeper than the 17% drop observed at Low settings. This suggests that at higher quality presets, the GPU's workload increases more rapidly as resolution climbs.

The Medium settings data provides the only min/max FPS readings in the dataset. At 1080p Medium, the average is 193 FPS with a minimum of 164 FPS and maximum of 222 FPS. At 1440p Medium, the average drops to 133 FPS with a minimum of 113 FPS and maximum of 153 FPS. At 4K Medium, the average falls to 79 FPS with a minimum of 67 FPS and maximum of 90 FPS. The spread between minimum and maximum FPS narrows as resolution increases — 58 FPS spread at 1080p, 40 FPS at 1440p, and 23 FPS at 4K. This tightening range at higher resolutions indicates that frame pacing becomes more consistent when the GPU is more heavily utilized.

Ultra settings show the steepest resolution scaling. The combo produces 124 FPS at 1080p, 85 FPS at 1440p, and 50 FPS at 4K. The 4K result of 50 FPS is the lowest measured value across the entire dataset. The drop from 1080p to 1440p is 31%, and from 1440p to 4K is 41%. These percentages align closely with the High settings scaling, suggesting that the relative performance penalty for resolution increases is consistent across the higher quality presets.

The data indicates that at 1080p, the CPU likely becomes the limiting component at lower settings, as evidenced by the 238 FPS Low result versus 193 FPS Medium — a relatively modest 19% drop. At 4K, the GPU is clearly the bottleneck, as the difference between Low and High settings is 117 FPS versus 66 FPS, a 44% reduction. The resolution scaling pattern therefore demonstrates a shift from CPU-bound behavior at 1080p Low to GPU-bound behavior at 4K across all settings.

For Rust, the CPU's role appears significant at lower resolutions and settings. At 1080p Low, the combo achieves 238 FPS, which is likely near the CPU's maximum frame delivery capability for this game. The modest 19% drop from Low to Medium settings at 1080p (238 to 193 FPS) suggests that the CPU is partially limiting performance, as the GPU workload increases without a proportional FPS reduction. At 1440p, the Low to Medium drop is 33% (198 to 133 FPS), showing the GPU becomes more involved. By 4K, the Low to Medium drop is 32% (117 to 79 FPS), similar to 1440p but at lower absolute values.

The nearest rivals to the Ryzen 7 7700 in average benchmark score include the AMD Ryzen AI 9 365 (0.1% higher), Intel Core 5 221E (0.2% lower), AMD Ryzen 9 270 (0.4% lower), and Intel Core i9-13905H (0.6% lower). These deltas are all under 1%, indicating the 7700 sits in a tightly contested performance tier. For Rust specifically, the 8-core/16-thread configuration with a 5.30 GHz boost clock provides strong single-thread performance for game logic and physics, while the 16 threads handle background tasks and compilation workloads common in this survival game.

Measured FPS Breakdown

The dataset contains 12 measured FPS entries covering three resolutions and four quality settings. At 1920x1080, the combo produces 238 FPS on Low, 193 FPS on Medium (164 min, 222 max), 163 FPS on High, and 124 FPS on Ultra. The progression from Low to Ultra shows a 48% reduction in average FPS, with each step up in quality costing roughly 15-19% performance. The Medium preset's min FPS of 164 is still higher than the Ultra average of 124, indicating that even the worst-case frame dips at Medium remain faster than the average experience at Ultra.

At 2560x1440, the results are 198 FPS on Low, 133 FPS on Medium (113 min, 153 max), 112 FPS on High, and 85 FPS on Ultra. The Low to Ultra reduction is 57%, steeper than at 1080p due to the increased pixel count. The Medium preset's min FPS of 113 is just 1 FPS above the High average of 112, suggesting that Medium's worst frames are comparable to High's typical frames. The max FPS at Medium of 153 is above the High average by 37%, showing that Medium can deliver substantially higher peak performance.

At 3840x2160, the combo delivers 117 FPS on Low, 79 FPS on Medium (67 min, 90 max), 66 FPS on High, and 50 FPS on Ultra. The Low to Ultra reduction is 57%, consistent with the 1440p scaling. The Medium preset's min FPS of 67 is notable because it stays above 60 FPS, while the High average of 66 FPS is just above that threshold. The Ultra average of 50 FPS falls below 60 FPS, making it the only setting/resolution combination that cannot maintain a consistent 60 FPS experience.

Comparing across resolutions at the same setting, the 1080p to 4K drops are 51% for Low, 59% for Medium, 60% for High, and 60% for Ultra. The Low setting shows a smaller relative drop, suggesting that at 1080p Low, the CPU is the bottleneck and moving to 4K does not proportionally reduce FPS. The 59-60% drops for Medium, High, and Ultra indicate a consistent GPU-bound scaling pattern once the CPU headroom is exhausted.

GPU Role

The NVIDIA GeForce RTX 4080 is based on the AD103 chip using the Ada Lovelace architecture, manufactured on a 5 nm process from TSMC. It features 9,728 shading units, 304 texture mapping units, and 112 raster output processors. The GPU has 76 ray tracing cores and 304 tensor cores, with a base clock of 2205 MHz and a boost clock of 2505 MHz. The memory subsystem consists of 16 GB of GDDR6X on a 256-bit bus, providing 716.8 GB/s of bandwidth at 22.4 Gbps effective speed.

In synthetic benchmarks, the RTX 4080 scores 34,457 in PassMark G3D and 20,671 in GPU compute. The Geekbench results show 214,739 for OpenCL and 263,779 for Vulkan. The 3DMark Steel Nomad DX12 score is 6,567. The GPU's percentile ranking of 86 versus all GPUs places it in the upper tier of the database. Its average benchmark score of 54,247 positions it close to the RTX 4080 SUPER (0.1% higher), while the AMD Radeon Pro W5700X is 1.1% higher and the AMD Radeon RX 6750 GRE 12 GB is 2.6% higher.

For Rust, the GPU's role becomes dominant at higher resolutions and settings. At 4K Ultra, the combo produces 50 FPS, indicating the GPU is fully saturated. The 16 GB VRAM capacity is unlikely to be a limiting factor for this game, as Rust's texture and asset demands are typically within this capacity at 4K. The 716.8 GB/s memory bandwidth provides ample throughput for the game's streaming and rendering needs.

The GPU's performance scaling across settings at 4K shows 117 FPS on Low, 79 FPS on Medium, 66 FPS on High, and 50 FPS on Ultra. This represents a 57% reduction from Low to Ultra. The incremental costs are 24% from Low to Medium, 16% from Medium to High, and 24% from High to Ultra. The larger jumps from Low to Medium and High to Ultra suggest that these preset transitions introduce more demanding rendering features, while the Medium to High step is comparatively modest.

At 1080p, the GPU has substantial headroom, as evidenced by 238 FPS on Low. However, the Ultra preset still only reaches 124 FPS, showing that even at 1080p, the most demanding settings can stress the GPU. The RTX 4080's 48.74 TFLOPS of FP32 compute and 280.6 GPixel/s pixel rate provide the raw throughput needed for Rust's rendering workloads, though the game's optimization characteristics determine how effectively this hardware is utilized.

Settings Recommendations

For 4K gaming, the measured data suggests that Medium settings (79 FPS average, 67 FPS minimum) provide the best balance of visual quality and performance. High settings at 4K drop to 66 FPS average, which is still above 60 FPS but offers less headroom for demanding scenes. Ultra at 4K drops to 50 FPS, which falls below the 60 FPS threshold and may result in noticeable stuttering during intense moments. Low at 4K produces 117 FPS, but the visual fidelity reduction is substantial for a game like Rust where visibility of distant structures and environmental details matters.

At 1440p, High settings (112 FPS) offer an excellent experience with plenty of headroom above 60 FPS and even above 100 FPS. Medium (133 FPS) provides additional performance for high-refresh-rate displays, while Ultra (85 FPS) remains playable and offers the best visual quality. For competitive play where frame rate is paramount, Low settings at 1440p deliver 198 FPS, which exceeds the refresh rate of most gaming monitors.

At 1080p, the choice depends on the refresh rate of the display. For 144 Hz monitors, Medium settings (193 FPS average, 164 FPS minimum) ensure that even the worst-case frame dips stay above the refresh rate. For 240 Hz displays, Low settings (238 FPS) are necessary to approach that refresh rate, though the 164 FPS minimum at Medium may still be acceptable. Ultra at 1080p produces 124 FPS, which suits 120 Hz displays but falls short of 144 Hz refresh rates.

The Medium preset across all resolutions provides the most consistent frame pacing, based on the min/max data available. At 1080p Medium, the spread is 58 FPS (164-222), at 1440p Medium it is 40 FPS (113-153), and at 4K Medium it is 23 FPS (67-90). The narrower spread at higher resolutions indicates more stable frame times, which can contribute to a smoother perceived experience despite lower average FPS.

For players prioritizing visual quality, High settings at 1440p (112 FPS) or 4K (66 FPS) deliver strong results. The jump from High to Ultra costs 24% performance at 4K (66 to 50 FPS) and 24% at 1440p (112 to 85 FPS), which may not justify the visual improvements depending on personal preference. The data suggests that High represents a sweet spot where the visual enhancements over Medium are significant, but the performance cost over Ultra is manageable.
