Microsoft Flight Simulator

The AMD Ryzen 9 5950X paired with the AMD Radeon RX 6700 XT delivers a highly playable experience in Microsoft Flight Simulator, though the data reveals a clear shift in bottleneck behavior as resolution increases. At 1080p, the system demonstrates strong headroom, with frame rates scaling dramatically between settings. Moving from Low to Ultra at 1920x1080, the average FPS drops from 121.7 to 65.5, a reduction of 56.2 frames that indicates the CPU and GPU are both contributing to the workload, but the graphics card is not yet saturated. At 1440p, the same settings span shows a tighter range, from 95.4 FPS on Low down to 51.8 FPS on Ultra. The scaling here is less steep than at 1080p, suggesting the GPU is beginning to take on a more dominant role. By 4K, the picture changes decisively. At 3840x2160, the average frame rate on Low is 70 FPS, but this collapses to 39.9 FPS on Ultra. The drop from Low to Ultra at 4K is a 30.1 FPS difference, which is proportionally smaller than the 56.2 FPS difference seen at 1080p, yet the absolute values are far lower. This pattern indicates that at 4K, the RX 6700 XT is the primary limiting factor, as the rendering load grows faster than the CPU can feed frames.

Resolution Scaling

The measured FPS data shows a consistent pattern of performance degradation as resolution climbs, but the rate of that degradation is not uniform across settings. At Low settings, the transition from 1080p to 1440p costs 26.3 FPS (from 121.7 to 95.4), while moving from 1440p to 4K costs another 25.4 FPS (from 95.4 to 70). This near-linear drop suggests that at Low settings, the system is largely unburdened, and the scaling is primarily driven by the GPU's pixel throughput. The RX 6700 XT, with its 12 GB of GDDR6 memory on a 192-bit bus delivering 384.0 GB/s, has enough bandwidth to handle the increased pixel count, but the raw compute power—13.21 TFLOPS FP32—begins to show its limits at higher resolutions.

At Ultra settings, the scaling is steeper in relative terms. The 1080p to 1440p transition drops from 65.5 to 51.8 FPS, a 13.7 FPS loss, while the 1440p to 4K transition drops from 51.8 to 39.9 FPS, an 11.9 FPS loss. This suggests that at Ultra, the game is pushing the GPU harder, and the additional pixel workload at 4K is compounded by the increased shading complexity. The data indicates that at 4K Ultra, the system is firmly GPU-bound, as the frame rate falls below the 40 FPS threshold, which is a significant drop from the 1080p result. The resolution scaling characteristics point to a system where 1080p and 1440p are the sweet spots for this combination, while 4K requires settings compromises to maintain smooth gameplay.

GPU Role

The AMD Radeon RX 6700 XT is the central component in determining the high-resolution performance ceiling. Its specifications—base clock of 2321 MHz, boost clock of 2581 MHz, and game clock of 2424 MHz—provide a solid foundation for this flight simulator. The GPU’s 12 GB of VRAM is a notable asset, as Microsoft Flight Simulator is known for loading large texture datasets, and the 192-bit memory bus with 384.0 GB/s bandwidth ensures the data can be fed to the shaders efficiently. The benchmark results show a PassMark G3D score of 19786, placing it in the 77th percentile of all GPUs, which indicates it sits above the median but is not a top-tier part.

The GPU’s nearest rivals in the benchmark database include the AMD Radeon RX 6800, which scores 33493 on average with a deltaPct of 0.7, meaning the RX 6700 XT is slightly behind. The data also lists the AMD Radeon HD 7950 and RX 480 as rivals with deltaPct values of -1, which is curious given their older architectures, but the average scores are close. The RX 6700 XT’s average benchmark score of 33721 suggests it is competitive with these parts, yet in actual game measurements, the GPU’s role becomes clearer. At 4K Ultra, the 39.9 FPS average indicates the GPU is struggling to maintain fluid motion, while at 1080p Low, the 121.7 FPS shows it has ample headroom. The RT cores, 40 in number, and the RDNA 2.0 architecture with DirectX 12 Ultimate support, do not appear to provide a significant advantage in this specific title, as the frame rates at 4K are modest.

CPU Role

The AMD Ryzen 9 5950X is a high-end desktop processor with 16 cores and 32 threads, based on the Zen 3 architecture on a 7 nm process. Its base clock of 3.40 GHz and boost clock of 4.90 GHz provide strong single-threaded performance, which is critical for flight simulators that often rely on a single main thread for game logic. The CPU’s benchmark scores confirm its capability: a Cinebench R23 multicore score of 38607 and a single-core score of 5450, with a PassMark single-thread score of 3470. The 3DMark single-thread score of 944 and 2-thread score of 1856 also indicate solid per-core performance.

The CPU’s role in the measured FPS is evident when comparing low-resolution results. At 1080p Low, the system achieves 121.7 FPS, which is a high frame rate that suggests the CPU is not the primary bottleneck at this setting. However, as settings increase to Ultra at 1080p, the FPS drops to 65.5, which is a 46.2% reduction. This drop is more likely attributed to the GPU’s increased workload, but the CPU’s 64 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are sufficient to avoid stalling. The CPU’s percentile rank of 93 among all CPUs places it in the top tier, and its nearest rivals include the Intel Core i5-14600K with a deltaPct of -0.2 and the Intel Xeon Gold 5318H with a deltaPct of 0.7, indicating the 5950X is competitive with these parts in synthetic benchmarks. In the game data, the CPU’s influence is most apparent at 1080p, where the frame rates are high enough to expose any CPU limitations, but the results show no obvious constraint, as the system scales well from Low to High settings before the GPU takes over.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system’s performance across three resolutions and four settings presets. At 1920x1080, the average frame rates are 121.7 FPS on Low, 93 FPS on Medium, 74.1 FPS on High, and 65.5 FPS on Ultra. The step from Low to Medium is a 28.7 FPS drop, while the step from Medium to High is an 18.9 FPS drop, and from High to Ultra is an 8.6 FPS drop. This diminishing return pattern shows that the largest performance hit comes from moving off Low settings, while the gap between High and Ultra is smaller, suggesting that Ultra adds visual fidelity without a proportional cost at this resolution.

At 2560x1440, the averages are 95.4 FPS on Low, 78.1 FPS on Medium, 57 FPS on High, and 51.8 FPS on Ultra. The difference between Low and Medium is 17.3 FPS, while the difference between High and Ultra is only 5.2 FPS. This indicates that at 1440p, the system is more sensitive to the Medium to High transition, which costs 21.1 FPS, and less sensitive to the High to Ultra transition. At 3840x2160, the averages are 70 FPS on Low, 53 FPS on Medium, 43.8 FPS on High, and 39.9 FPS on Ultra. The drop from Low to Medium is 17 FPS, from Medium to High is 9.2 FPS, and from High to Ultra is 3.9 FPS. The 4K results show that the system is heavily GPU-bound, with even the Low preset struggling to reach 70 FPS, and Ultra dipping below 40 FPS.

How This Combo Ranks

In the database of tested combinations for Microsoft Flight Simulator, this pairing of the Ryzen 9 5950X and RX 6700 XT holds the 979th position out of 1795 total combos. This rank places it in the middle of the pack, which is notable given the high-end nature of the CPU and the mid-range positioning of the GPU. The percentile rank for the CPU is 93, indicating it outperforms 93% of all CPUs in synthetic tests, while the GPU’s percentile is 77, showing it beats 77% of all GPUs. The combination of a top-tier CPU with a mid-range GPU results in a balanced system, but the rank suggests that many other combinations, likely with stronger GPUs, achieve higher frame rates in this specific title.

The combo’s rank of 979 out of 1795 means it sits at approximately the 54.5th percentile of tested combos. This is a reasonable position, considering that Microsoft Flight Simulator is a demanding title that favors high-end GPUs. The data shows that the CPU’s strong single-threaded performance helps at lower resolutions, but the GPU becomes the limiting factor at higher resolutions, which likely explains why the combo does not rank higher. The measured FPS at 4K Ultra of 39.9 FPS is below the 60 FPS target that many users prefer, and this is a direct consequence of the GPU’s capabilities rather than the CPU.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend heavily on the target resolution. At 1920x1080, the High preset delivers an average of 74.1 FPS, which is a smooth experience for most users. The Ultra preset at 65.5 FPS is also playable, but the 8.6 FPS gain from High to Ultra may not justify the additional visual load. For users seeking maximum frame rates, the Low preset at 121.7 FPS is an option, but it sacrifices significant visual quality. The Medium preset at 93 FPS offers a balance, providing a 25.4% improvement over High while maintaining decent visuals.

At 2560x1440, the High preset drops to 57 FPS, which is borderline for smooth gameplay, while Medium at 78.1 FPS is a better choice for consistent performance. The Ultra preset at 51.8 FPS is below the 60 FPS threshold, so it is not recommended unless the user prioritizes visual fidelity over frame rate. The Low preset at 95.4 FPS is the only setting that comfortably exceeds 60 FPS at this resolution, but it comes with a significant visual penalty. For 1440p, the Medium preset appears to be the sweet spot, offering a playable frame rate without excessive compromise.

At 3840x2160, the situation is more constrained. The Low preset at 70 FPS is the only setting that achieves a playable frame rate, while Medium at 53 FPS is borderline, and High at 43.8 FPS and Ultra at 39.9 FPS are below the threshold for smooth gameplay. For 4K, the Low preset is the recommended choice if the user wants to maintain fluid motion, while Medium is acceptable for users who can tolerate occasional dips. The data clearly shows that this combo is not suited for 4K Ultra, and users should either lower settings or reduce resolution to achieve a better experience.
