Microsoft Flight Simulator

Microsoft Flight Simulator presents a demanding workload that scales significantly with resolution, and the combination of the AMD Ryzen 5 5600F and AMD Radeon RX 7700 XT shows a clear shift in bottleneck behavior. At 1080p, the system delivers high frame rates that exceed 100 FPS on lower presets, but the transition to 4K reveals the GPU as the primary limiting factor, with average frame rates dropping by nearly half. The measured data indicates that this pairing is well-suited for high-refresh-rate 1080p and 1440p gaming, while 4K requires more conservative settings to maintain smooth performance.

Resolution Scaling

The measured FPS data reveals a pronounced scaling curve from 1080p to 4K, indicating that the Radeon RX 7700 XT becomes increasingly stressed as pixel count rises. At the Low preset, the average frame rate drops from 139 FPS at 1920x1080 to 112 FPS at 2560x1440, a reduction of approximately 19%, and then further to 82 FPS at 3840x2160, which is a 41% decline from the 1080p result. This steep drop at 4K highlights the GPU's memory bandwidth and shading throughput as the limiting factors, as the 12 GB VRAM and 432.0 GB/s bandwidth are challenged by the higher resolution demands.

The Medium preset shows a similar trend, with average FPS falling from 108 at 1080p to 87 at 1440p, and then to 64 at 4K. The gap between 1080p and 4K here is 44 FPS, or roughly 41%, which mirrors the Low preset's scaling. This consistency suggests that the GPU's rendering pipeline is the dominant constraint across these settings, rather than CPU-side bottlenecks. Notably, the Medium preset at 4K also reports a minimum FPS of 55 and a maximum of 74, indicating some frame time variance that could be perceptible in flight simulation scenarios.

The High preset results continue this pattern, with average FPS of 81 at 1080p, 65 at 1440p, and 48 at 4K. The percentage drop from 1080p to 4K is approximately 41%, again aligning with the other presets. This uniformity across settings implies that the scaling is resolution-driven, not settings-driven, which is typical for a GPU-limited scenario at higher resolutions. The Ultra preset shows the lowest absolute numbers, with 77 FPS at 1080p, 62 at 1440p, and 46 at 4K, but the relative drop from 1080p to 4K is about 40%, consistent with the overall trend.

What the data indicates is that the CPU, with its 6 cores and 12 threads based on Zen 3 architecture, is capable of feeding the GPU adequately at 1080p, as evidenced by the high frame rates on lower presets. However, as resolution increases, the GPU's workload scales non-linearly, and the RX 7700 XT's compute resources become the bottleneck. The 4K results, particularly at High and Ultra presets, fall below the 60 FPS threshold, suggesting that users targeting 4K should opt for Medium or Low settings to maintain playable performance. The 1440p results, in contrast, show that High and Ultra presets remain above 60 FPS, making this resolution the sweet spot for visual fidelity and performance balance.

GPU Role

The AMD Radeon RX 7700 XT plays a central role in determining the frame rates at higher resolutions, as evidenced by the measured FPS data. The GPU is built on the RDNA 3.0 architecture with a Navi 32 chip, featuring 3456 shading units and 96 ROPs. Its boost clock of 2544 MHz and game clock of 2171 MHz contribute to a peak FP32 throughput of 35.17 TFLOPS, which is the primary driver of pixel and texture processing in this flight simulator.

The memory subsystem consists of 12 GB of GDDR6 on a 192-bit bus, providing 432.0 GB/s of bandwidth. This configuration is adequate for 1080p and 1440p, as the frame rates at these resolutions remain high even on Ultra settings. However, at 4K, the data shows a consistent reduction of roughly 40% in average FPS across all presets, which correlates with the increased memory pressure and shading workload. The 4K Medium preset's minimum FPS of 55 indicates that the GPU's memory bandwidth is strained, leading to potential frame dips in complex scenes.

The GPU's benchmark scores reflect its mid-range positioning, with a Passmark G3D score of 22547 and a percentile rank of 67 among all GPUs. Its nearest rival, the NVIDIA GeForce RTX 5060 Mobile, scores 22435, a 0.5% delta, while the RTX 2080 scores 22895, a -1.5% delta. This places the RX 7700 XT in a competitive position, but the measured in-game data shows that Microsoft Flight Simulator's demands are substantial enough to push the GPU to its limits at 4K.

The GPU's TDP of 245 W and dual-slot design indicate it is a power-hungry component, but the performance data shows that it can deliver high frame rates when not constrained by resolution. The 1080p results, with Low averaging 139 FPS and Ultra at 77 FPS, demonstrate that the GPU has ample headroom at lower resolutions. The scaling to 4K reveals that the GPU's compute resources, rather than the CPU, are the limiting factor, as the Ryzen 5 5600F's specifications—6 cores, 12 threads, and a 32 MB L3 cache—are sufficient to avoid bottlenecking in this title.

The GPU's Passmark G3D score of 22547 is consistent with its average, showing that it performs reliably across different benchmark workloads.

The combo's rank of 1060 suggests that while the individual components are above average, the pairing does not synergize to produce top-tier results in this specific game. This is likely due to the demanding nature of Microsoft Flight Simulator, which stresses both the CPU and GPU heavily. The 4K performance, which falls below 60 FPS on High and Ultra presets, contributes to a lower overall rank compared to systems with more powerful GPUs that can maintain higher frame rates at higher resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For 1920x1080, the High preset provides an average of 81 FPS, which is smooth for most flight simulation scenarios. The Ultra preset at 77 FPS offers a marginal improvement in visual quality with only a 4 FPS penalty, making it a viable choice for users with 60 Hz monitors. For those seeking maximum frame rates, the Low preset at 139 FPS is available, but the visual fidelity reduction may not be worth the performance gain.

At 2560x1440, the High preset averages 65 FPS, which is above the 60 FPS threshold and provides a good balance of visual quality and performance. The Ultra preset at 62 FPS is also playable, offering a 3 FPS reduction for higher settings. The Medium preset at 87 FPS is a strong option for users who prioritize frame rate stability, as it provides a significant performance buffer above the 60 FPS minimum. The Low preset at 112 FPS is excessive for most users, but it could be useful for competitive play or when using high-refresh-rate displays.

For 3840x2160, the Medium preset is the highest that maintains playable performance, averaging 64 FPS with a minimum of 55 FPS. The High preset at 48 FPS and Ultra at 46 FPS fall below the 60 FPS threshold, which may result in noticeable stutter in a flight simulator where smooth visuals are important. The Low preset at 82 FPS is the only option that provides comfortable headroom at 4K, but it sacrifices significant visual detail. Users with 4K displays should prioritize the Medium preset as a starting point and adjust settings based on their sensitivity to frame rate fluctuations.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across resolutions and settings. At 1920x1080, the Low preset delivers an average of 139 FPS, the Medium preset averages 108 FPS with a minimum of 92 and maximum of 124, the High preset averages 81 FPS, and the Ultra preset averages 77 FPS. The spread from Low to Ultra is 62 FPS, showing a significant impact from graphical settings at this resolution.

At 2560x1440, the Low preset averages 112 FPS, the Medium preset averages 87 FPS with a minimum of 74 and maximum of 100, the High preset averages 65 FPS, and the Ultra preset averages 62 FPS. The difference between Low and Ultra is 50 FPS, indicating that settings have a substantial effect on performance even at this resolution.

At 3840x2160, the Low preset averages 82 FPS, the Medium preset averages 64 FPS with a minimum of 55 and maximum of 74, the High preset averages 48 FPS, and the Ultra preset averages 46 FPS. The gap between Low and Ultra is 36 FPS, which is smaller than at lower resolutions, confirming that the GPU is the limiting factor at 4K. The Medium preset's minimum FPS of 55 is the only sub-60 value recorded across all measured points, suggesting that frame dips are more pronounced at higher resolutions.

The data also shows that the scaling from 1080p to 1440p results in an average FPS reduction of approximately 20-25% across all presets, while the scaling from 1440p to 4K results in a reduction of approximately 25-30%. This non-linear scaling is characteristic of a GPU-bound scenario, where the rendering workload increases exponentially with pixel count. The 4K results, particularly at High and Ultra, indicate that the RX 7700 XT is not sufficiently powerful for maxed-out settings at this resolution, and users should plan their settings accordingly.
