Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title, and the data for the AMD Ryzen 9 5900X paired with the AMD Radeon RX 6700 XT shows a system that is capable but requires careful settings management to hit high frame rates. The measured results across three resolutions and four quality presets reveal a clear performance hierarchy, with the GPU acting as the primary bottleneck in most scenarios. This analysis breaks down the measured FPS to explain where the hardware excels, where it struggles, and how to configure the game for the best experience.

Resolution Scaling

The FPS drop from 1080p to 4K is significant, confirming that this system is heavily GPU-limited at higher resolutions. At Low settings, the average frame rate falls from 123.2 FPS at 1920x1080 to 97.9 FPS at 2560x1440, a 20.5% decrease. Moving to 3840x2160, the average plummets to 68.9 FPS, which is a 44.1% reduction from the 1080p result. This steep decline indicates that the Radeon RX 6700 XT's rendering throughput is the limiting factor as pixel count increases.

The pattern persists across all quality presets. At High settings, the average FPS drops from 69.0 at 1080p to 58.7 at 1440p and then to 40.4 at 4K. The gap between 1440p and 4K remains consistently large, suggesting that the jump to 4K requires nearly double the pixel processing power, which the GPU cannot provide. The data shows that 1080p is the only resolution where this combination can consistently exceed 60 FPS on higher presets, while 1440p is playable but requires a mix of Medium and High settings to stay smooth. 4K is only viable on Low settings, where the 68.9 FPS average is borderline for a flight sim but still represents a playable experience. The scaling behavior indicates that for 4K gaming, a more powerful GPU would be necessary, while the CPU has ample headroom.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, with a base clock of 3.70 GHz and a boost clock of 4.80 GHz. Its benchmark results are strong, with a Cinebench R23 multi-core score of 33150 and a single-core score of 4680. This processing power is crucial for Microsoft Flight Simulator, which simulates complex physics, weather, and AI traffic. However, the measured FPS data suggests that the CPU is not the primary constraint in most tested configurations.

The evidence for this lies in the FPS scaling with resolution. At 1080p with Low settings, the system achieves 123.2 FPS, which is a high frame rate that requires solid single-thread performance. Yet, when the resolution is increased to 4K, the FPS drops dramatically to 68.9 FPS at the same Low preset. If the CPU were the bottleneck, the FPS would remain relatively flat across resolutions, as the CPU work would not change. Instead, the FPS drops, indicating that the GPU is struggling to keep up with the increased pixel load. The CPU's 64 MB of L3 cache and high single-core score (3469 in Passmark) help maintain minimum frame rates in complex scenes, but the overall average is dictated by the GPU.

In comparison to its nearest rivals, the Ryzen 9 5900X holds its own, with an average benchmark score of 39453. It sits within 1% of the Intel Core i7-13700 and AMD EPYC 4245P, and is 0.7% behind the AMD Ryzen 7 PRO 8845HS. This indicates that for this game, the CPU is not a weak link; it provides consistent performance that allows the GPU to be the deciding factor. The data suggests that the processor is more than capable of feeding the Radeon RX 6700 XT, and users should focus on GPU settings to improve frame rates.

GPU Role

The AMD Radeon RX 6700 XT is the clear performance limiter in this configuration, based on the measured data. It features 12 GB of GDDR6 memory on a 192-bit bus, providing 384.0 GB/s of bandwidth. Its boost clock is 2581 MHz, and it has a high pixel rate of 165.2 GPixel/s. These specifications are respectable, but the FPS results show that the card is stretched thin at higher resolutions and quality settings. The GPU's average benchmark score is 33721, placing it in the 77th percentile of all GPUs, but its nearest rivals include the RX 6800, which is only 0.7% faster in average score.

The impact of the GPU is most visible in the difference between Low and Ultra settings. At 1080p, the average FPS drops from 123.2 on Low to 67.3 on Ultra, a 45.4% reduction. This is a massive performance hit for a single quality tier jump, indicating that the Ultra preset's effects (shadows, textures, volumetric clouds) are extremely taxing on the GPU. At 4K, the difference is less pronounced in absolute terms (68.9 FPS on Low vs 40.3 FPS on Ultra), but the relative cost is similar. The 12 GB of VRAM is likely sufficient for the tested presets, but the GPU's compute power is insufficient for smooth 4K gameplay at high settings.

The GPU's performance relative to its rivals is telling. It is 1.3% faster than the NVIDIA RTX A5000 and 1% slower than the AMD Radeon RX 480 in average benchmark score, which is an odd comparison group. However, the practical data shows this is a mid-range card that excels at 1080p and can handle 1440p with adjustments. For Microsoft Flight Simulator, users should treat the RX 6700 XT as a 1080p-to-1440p card, not a 4K solution, unless they are willing to accept lower frame rates or reduced visual quality.

Settings Recommendations

Based on the measured FPS rows, the optimal balance of visual quality and performance is achieved with the Medium preset at 1440p. The data shows an average FPS of 75.4 at 2560x1440 on Medium, which is smooth and playable for a flight simulator. This setting provides a significant visual upgrade over Low (97.9 FPS) while maintaining a comfortable margin above the 60 FPS threshold. At 1080p, the High preset delivers 69.0 FPS, which is also a solid choice if the user prioritizes detail over resolution. However, the Medium preset at 1080p (92.2 FPS) offers a more consistent experience, especially in busy airport areas where frame rates can dip.

For users with 4K displays, the data clearly shows that High and Ultra presets are not viable, with averages of 40.4 and 40.3 FPS respectively. The Low preset at 4K (68.9 FPS) is the only option that approaches playability, but it sacrifices many visual features that make the game immersive. A better approach is to run the game at 2560x1440 on Medium or High settings, which looks good on a 4K monitor and stays well within the performance envelope. The Ultra preset is only recommended for screenshot purposes or if the user has a variable refresh rate monitor and can tolerate frame rates in the 40-50 FPS range, as seen at 1080p (67.3 FPS) and 1440p (51.4 FPS).

FAQ

Q: Can this system run Microsoft Flight Simulator at 4K?

A: Yes, but only on Low settings, where the measured average FPS is 68.9. At Medium settings, the average drops to 52.8 FPS, which is not smooth. High and Ultra presets at 4K produce averages of 40.4 and 40.3 FPS, which are too low for a consistent experience.

Q: What is the best resolution for this CPU/GPU combo?

A: The data indicates that 2560x1440 on Medium settings provides the best balance, with an average FPS of 75.4. This resolution also offers a good visual upgrade over 1080p without the steep performance cost of 4K.

Q: Is the CPU or GPU the bottleneck in this game?

A: The GPU is the primary bottleneck. Evidence shows that FPS drops significantly when resolution increases at the same settings, which is a classic sign of GPU limitation. The CPU's strong single-thread performance (4680 in Cinebench R23) is sufficient to avoid holding back the GPU.

Q: How much performance is lost going from High to Ultra settings?

A: At 1080p, the average FPS drops from 69.0 on High to 67.3 on Ultra, a small 2.4% loss. At 1440p, the drop is more significant, from 58.7 on High to 51.4 on Ultra, a 12.4% loss. The Ultra preset is not worth the performance cost at higher resolutions.

Q: Should I use the Low preset for competitive multiplayer?

| 1920x1080 | Low | 123.2 |

The data shows a clear pattern: at each settings level, the FPS decreases as resolution increases. The largest single jump in performance cost is moving from 1440p to 4K, particularly on High settings where the average FPS falls from 58.7 to 40.4. At 1080p, the difference between Low and Ultra is 55.9 FPS, while at 4K, the same settings difference is only 28.6 FPS, suggesting that the GPU is so saturated at 4K that additional settings have a smaller relative impact. For the best experience, prioritize 1440p Medium, which yields 75.4 FPS, or 1080p High, which yields 69.0 FPS, depending on the user's display and preference for resolution versus detail. The Ultra preset is only playable at 1080p (67.3 FPS) and should be avoided at 1440p and 4K.
