GPU Role

The AMD Radeon RX 7800 XT is the primary driver of visual output, and its specifications directly influence the measured results. With a base clock of 1295 MHz and a boost clock of 2430 MHz, the GPU's performance scaling is evident when moving between settings presets. The 16 GB of GDDR6 memory is a critical asset for Microsoft Flight Simulator, as the game's high-resolution textures and detailed scenery can consume significant memory capacity. The 256-bit memory bus, paired with a bandwidth of 624.1 GB/s, ensures that this capacity is fed efficiently, which is particularly relevant at higher resolutions like 2560x1440 and 3840x2160 where data transfer demands increase.

The GPU's architecture, RDNA 3.0, is built on a 5 nm process and features 3840 shading units and 96 ROPs. These specifications contribute to its ability to handle the game's complex lighting and shadow calculations. The pixel rate of 233.3 GPixel/s and texture rate of 583.2 GTexel/s provide theoretical ceilings that the measured FPS data aligns with. For instance, the difference between the Ultra preset, which averages 48.4 FPS at 4K, and the Low preset, which averages 84.2 FPS at the same resolution, demonstrates how the GPU's workload scales with graphical complexity. The data suggests that the GPU is not the limiting factor at lower resolutions, but it becomes more stressed as resolution increases, evidenced by the FPS drop from 144.9 at 1080p Low to 84.2 at 4K Low.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends heavily on the target resolution and desired frame rate. At 1920x1080, the High preset delivers an average of 86 FPS, which is a solid balance between visual fidelity and smoothness, while the Ultra preset only drops this to 80.9 FPS. For users prioritizing maximum frame rates at this resolution, the Low preset achieves 144.9 FPS, but the Medium preset at 113.2 FPS offers a more balanced experience.

Moving to 2560x1440, the High preset provides an average of 70.3 FPS, which is generally acceptable for a flight simulator. The Ultra preset at 69.1 FPS is nearly identical, suggesting diminishing returns from the extra graphical load. The Medium preset at 91.2 FPS is a strong recommendation for those wanting headroom, as it provides a significant boost over High without a substantial visual compromise. At 3840x2160, the Medium preset averages 69.9 FPS, making it the most practical choice for 4K play, as the High preset drops to 52.3 FPS and the Ultra preset falls to 48.4 FPS, which may be too low for some users. The Low preset at 84.2 FPS remains viable for competitive or high-refresh-rate 4K displays.

Measured FPS Breakdown

The measured data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the frame rates are consistently high, with the Low preset leading at 144.9 FPS, followed by Medium at 113.2 FPS, High at 86 FPS, and Ultra at 80.9 FPS. This shows a clear progression where each settings tier reduces performance, but even the most demanding Ultra preset maintains an average above 80 FPS.

At 2560x1440, the performance scales down predictably. The Low preset averages 117.8 FPS, which is a modest drop from the 1080p result. The Medium preset averages 91.2 FPS, while the High and Ultra presets produce nearly identical results at 70.3 and 69.1 FPS respectively. This indicates that at 1440p, the difference between High and Ultra settings has minimal impact on frame rate, suggesting the CPU or other system components are beginning to play a more significant role.

At 3840x2160, the GPU workload becomes more demanding. The Low preset averages 84.2 FPS, the Medium preset averages 69.9 FPS, the High preset averages 52.3 FPS, and the Ultra preset averages 48.4 FPS. The gap between Low and Medium is 14.3 FPS, while the gap between Medium and High is 17.6 FPS, and the gap between High and Ultra is 3.9 FPS. This pattern shows that the transition from Medium to High has the most significant performance cost at 4K, while the jump from High to Ultra is relatively minor.

Resolution Scaling

The performance drop from 1080p to 4K reveals important insights about the system's bottleneck. At the Low settings preset, the average FPS decreases from 144.9 at 1920x1080 to 117.8 at 2560x1440, a reduction of 27.1 FPS, and then to 84.2 at 3840x2160, a further reduction of 33.6 FPS. This represents a total drop of 60.7 FPS from 1080p to 4K, or approximately 42% of the 1080p performance. This scaling suggests that the GPU is the primary limiting factor at higher resolutions, as the pixel count increases significantly.

At the Ultra settings preset, the FPS drops from 80.9 at 1080p to 69.1 at 1440p, a decrease of 11.8 FPS, and then to 48.4 at 4K, a further decrease of 20.7 FPS. The total drop of 32.5 FPS represents a 40% reduction from the 1080p baseline. The similarity in the percentage drop between Low and Ultra settings indicates that resolution scaling affects the system consistently regardless of graphical load, confirming that the GPU's rendering capabilities are the key constraint. The Ryzen 9 5900X, with its high multi-threaded performance ranking in the 90th percentile among all CPUs, appears to be more than capable of feeding the GPU, as evidenced by the fact that frame rates drop in near-linear fashion with resolution rather than showing signs of CPU stalling.
