Microsoft Flight Simulator

The AMD Ryzen 7 5800XT and AMD Radeon RX 7800 XT combination delivers a highly playable Microsoft Flight Simulator experience across the board, with the data revealing a clear shift in system bottleneck as resolution increases. The measured frames per second (FPS) at 1080p and 1440p suggest a CPU-leaning workload at lower settings, while 4K results place the emphasis squarely on the GPU, a classic pattern for this simulation title.

Resolution Scaling

The transition from 1080p to 4K produces a substantial performance hit, but the magnitude of that drop is heavily dependent on the graphics preset. At the Low preset, the average FPS falls from 147.5 at 1920x1080 to 119.4 at 2560x1440, a reduction of roughly 19%. Pushing further to 3840x2160 brings the average down to 86.1, which represents a 41.6% decrease from the 1080p baseline. This scaling pattern indicates that even at Low settings, the GPU is still the limiting factor at higher resolutions, though the 5800XT's strong single-thread performance keeps the CPU from becoming a major constraint.

The High preset shows a similar trend but with a more pronounced drop at 4K. Starting at 85.7 FPS at 1080p, the average dips to 71.1 at 1440p, a 17% reduction, before falling to 48 at 2160p. That final step from 1440p to 4K represents a 32.5% loss in performance, which is a steeper decline than the 1080p to 1440p transition. This suggests that the RX 7800 XT's 16 GB memory buffer and 624.1 GB/s bandwidth are being taxed heavily at 4K with High settings, as the pixel count and texture detail begin to saturate the GPU's capabilities.

The Ultra preset delivers the most demanding workload, with averages of 84.1 at 1080p, 68.8 at 1440p, and 50.6 at 4K. The scaling from 1080p to 1440p is a 18.2% reduction, while the leap to 4K costs another 26.5% of performance. Interestingly, the gap between High and Ultra at 1080p is minimal, with only 1.6 FPS separating them, but at 4K the difference widens to 2.6 FPS. This indicates that the CPU can keep pace with the higher preset at lower resolutions, but at 4K the GPU's rendering load becomes the primary constraint.

A key observation is the relationship between the Low and Ultra presets across resolutions. At 1080p, the spread between them is 63.4 FPS, reflecting the CPU's ability to feed frames quickly when the GPU is less burdened. At 4K, this spread narrows to 35.5 FPS, as the GPU's raw throughput becomes the dominant factor. The data suggests that for users targeting high refresh rates at 1080p, the CPU is doing more of the heavy lifting, while at 4K the RX 7800 XT's 37.32 TFLOPS of FP32 performance and 233.3 GPixel/s pixel rate are the key determinants of final frame rates.

Settings Recommendations

For users prioritizing a smooth experience at 1920x1080, the High preset is the clear winner, delivering 85.7 FPS while maintaining substantial visual detail. The Ultra preset offers only 1.6 FPS more, which is within the margin of error and not worth the extra load on the system. The Medium preset at 114.7 FPS is also viable for high refresh rate displays, but the jump from Medium to High is only 29 FPS, making High the best compromise between image quality and speed.

At 2560x1440, the Medium preset stands out with a 90.3 FPS average, providing a solid baseline for 60 Hz and entry-level 144 Hz monitors. The High preset at 71.1 FPS is still playable but represents a 21% performance loss for marginal visual gains. The data suggests that users should stick with Medium at 1440p to keep frame rates comfortably above 60, while those with adaptive sync displays might find the 68.8 FPS of Ultra acceptable.

For 4K, the situation is more constrained. The Low preset at 86.1 FPS is the only setting that provides a comfortable margin above 60 FPS, making it the recommended choice for most users. The Medium preset at 65.7 FPS is borderline, and while it is playable, it leaves little headroom for complex scenes with dense scenery or weather effects. The High and Ultra presets, at 48 and 50.6 FPS respectively, are best reserved for users who prioritize visual fidelity over smoothness and are willing to accept lower frame rates in a non-competitive simulation context.

Measured FPS Breakdown

At 1920x1080, the full range of presets shows strong performance. The Low preset leads with 147.5 FPS, followed by Medium at 114.7 FPS, then High at 85.7 FPS, and finally Ultra at 84.1 FPS. The difference between High and Ultra is negligible, suggesting that the Ultra preset's additional effects are not heavily taxing the RX 7800 XT at this resolution. The gap between Low and Medium is 32.8 FPS, indicating that Medium is a significant step up in visual fidelity without a proportional frame rate penalty.

Moving to 2560x1440, the order remains the same but the margins shift. Low is 119.4 FPS, Medium is 90.3 FPS, High is 71.1 FPS, and Ultra is 68.8 FPS. The reduction from 1080p to 1440p is consistent across presets, averaging around 18-20%, which shows that the GPU is scaling predictably with pixel count. The High and Ultra presets are nearly identical here, with only 2.3 FPS separating them, reinforcing the idea that the Ultra preset offers minimal returns at this resolution.

At 3840x2160, the performance curve becomes steeper. Low is 86.1 FPS, Medium is 65.7 FPS, High is 48 FPS, and Ultra is 50.6 FPS. Notably, the Ultra preset outperforms High by 2.6 FPS, which is an anomaly in the data. This could be due to specific rendering paths or CPU-GPU interaction effects, but the result is consistent with the measured rows. The drop from Medium to High is 17.7 FPS, a 27% reduction, which is the largest single-step decline across all resolutions, highlighting the strain of High settings at 4K.

GPU Role

The AMD Radeon RX 7800 XT plays a decisive role in shaping Microsoft Flight Simulator's performance, particularly as resolution increases. The GPU's base clock is 1295 MHz with a boost clock of 2430 MHz, and its game clock is rated at 2124 MHz. These clocks, combined with the 3840 shading units and 240 texture mapping units, provide the compute power necessary to handle the game's complex rendering of terrain, weather, and aircraft models. The 96 ROPs deliver a pixel rate of 233.3 GPixel/s, which is critical for filling the screen at 4K resolutions.

The 16 GB of GDDR6 memory on a 256-bit bus provides 624.1 GB/s of bandwidth. In this game, the data shows that at 1080p, the GPU is not the primary bottleneck, as evidenced by the 147.5 FPS at Low settings. However, at 4K, the GPU's raw compute becomes the limiting factor, with the Ultra preset only reaching 50.6 FPS. The memory configuration appears sufficient, as there is no indication of a stutter or frame time issue typically associated with memory capacity limits, but the bandwidth is taxed by the high resolution.

The GPU's position in the market is solid, with an average benchmark score of 32619, placing it in the 76th percentile of all GPUs. Its nearest rivals are all within 0.7% of its score, indicating that this card is well-matched against its direct competitors. In the context of this game, the RX 7800 XT's performance at 4K with High settings (48 FPS) is the weakest result measured, but the Low preset's 86.1 FPS shows that the card has substantial headroom when settings are dialed back. The GPU's DirectX 12 Ultimate support and 12_2 feature level are relevant for the flight simulator's use of modern rendering features, though the measured data does not isolate specific API performance. The RX 7800 XT's 263 W TDP and dual-slot design suggest it is a power-hungry card, but its performance in this benchmark demonstrates that it is capable of delivering playable frame rates across most resolution and setting combinations.
