Microsoft Flight Simulator

# Microsoft Flight Simulator with AMD Ryzen 9 9950X3D + AMD Radeon RX 6600 XT

The AMD Ryzen 9 9950X3D pairs a 16-core, 32-thread Zen 5 design with a 4.30 GHz base and 5.70 GHz boost clock, backed by 128 MB of shared L3 cache. Its benchmark profile shows a 96th percentile standing among all CPUs, with a Cinebench R23 multi-core score of 59712 and a single-core score of 8430. The Radeon RX 6600 XT, built on RDNA 2.0 with 2048 shading units and 8 GB of GDDR6 memory on a 128-bit bus, sits at the 71st percentile among GPUs. In Microsoft Flight Simulator, this combination produces a measured performance spread that reveals both the CPU's headroom and the GPU's constraint points across resolutions and settings.

CPU Role — cores, clocks, and how they relate to this game's results

Microsoft Flight Simulator is known for heavy single-threaded demands, but the data here shows a more complex picture. The 9950X3D's single-thread performance — a Geekbench single-core score of 3401 and a 3DMark single-thread score of 1292 — provides a strong foundation for the game's simulation logic. The CPU's 16 cores and 32 threads, combined with a 128 MB L3 cache, ensure that background tasks, terrain streaming, and physics calculations do not become bottlenecks in most scenarios. The 4.30 GHz base clock and 5.70 GHz boost clock allow the processor to scale up quickly when the game requests additional compute.

What the measured FPS data suggests is that at 1080p Low, the combo reaches 102 FPS, a figure that likely approaches the CPU's limit for this title. At 1080p Ultra, the average drops to 56.1 FPS, indicating that the GPU is now the primary constraint. The CPU's 3DMark multi-thread score of 17184 and Cinebench R23 multi-core score of 59712 demonstrate ample parallel processing capability, but Flight Simulator's engine does not appear to scale perfectly with all 32 threads. The 9950X3D's nearest rivals in average benchmark score include the AMD Ryzen 9 9950X at a 1.8% delta and the Intel Core i7-14700KF at 2.2%, meaning the 3D V-Cache variant offers only a marginal average-score advantage over its non-X3D sibling, yet the game-specific results show the CPU is rarely the limiting factor until very low resolutions and presets.

FAQ

Q: What is the highest average FPS this combo achieves in the measured data?

A: The peak measured average is 102 FPS at 1920x1080 with Low settings. This is the only preset where the combo crosses the 100 FPS threshold.

Q: How does the CPU compare to its nearest rival in average benchmark score?

A: The 9950X3D has an average benchmark score of 71660, which is 0.9% higher than the Intel Xeon Platinum 8270 (71056) and 1.8% higher than the AMD Ryzen 9 9950X (70420). It sits 1.9% below the Intel Xeon 6517P (73050).

Q: Does the GPU bottleneck appear at 1440p or 4K?

A: Yes. At 2560x1440 Ultra, the average FPS is 47.7, while at 3840x2160 Ultra it drops to 31 FPS. These figures, combined with the 1080p results, show the RX 6600 XT is the limiting component at higher resolutions and settings.

Q: What is the combo's rank among all tested combinations in this game?

A: The combo ranks 1235 out of 1795 tested combinations, placing it in the lower-middle portion of the database for Microsoft Flight Simulator.

Q: How much faster is the 1080p Low result compared to the 4K Ultra result?

A: The 1080p Low average of 102 FPS is more than three times the 4K Ultra average of 31 FPS, representing a 71 FPS difference.

Q: What does the L3 cache size of 128 MB do for this game?

A: The 128 MB shared L3 cache helps keep frequently accessed terrain and aircraft data close to the cores, which can reduce memory latency. The measured results show strong 1080p Low performance (102 FPS), suggesting the cache helps maintain high frame rates when the GPU is not the bottleneck.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The scaling pattern across resolutions is instructive. At Low settings, the average FPS drops from 102 at 1080p to 80.3 at 1440p (a 21.3% decrease), then to 57.4 at 4K (a 28.5% decrease from 1440p). This progressive decline indicates a GPU-bound scenario at Low settings, where the RX 6600 XT's 256.0 GB/s memory bandwidth and 10.60 TFLOPS FP32 compute become the constraining factors.

At Medium settings, the pattern is similar but with a steeper initial drop: 79.6 FPS at 1080p falls to 64.7 at 1440p (18.7% lower), then to 48.1 at 4K (25.7% lower than 1440p). The High preset shows a more compressed range: 58.1 at 1080p, 44.4 at 1440p, and 36.6 at 4K. The Ultra preset exhibits the smallest proportional drop from 1080p to 1440p (47.7 vs 56.1, a 15% reduction) but the largest absolute decline at 4K, reaching 31 FPS.

The 1080p Low result of 102 FPS stands out because it is the only measurement above 100, suggesting that at this resolution and setting, the CPU's strong single-thread performance (Geekbench single-core 3401) is sufficient to feed the GPU. As resolution increases, the pixel throughput demand grows, and the RX 6600 XT's 8 GB VRAM and 128-bit memory interface become progressively more limiting. The data indicates that the CPU is not the primary bottleneck at any resolution above 1080p Low, and even at 1080p Medium (79.6 FPS), the GPU is likely the limiting factor.

How This Combo Ranks — use comboRankInGame vs other tested combos

With a rank of 1235 out of 1795 tested combinations, this pairing sits in the 31st percentile of all combos tested in Microsoft Flight Simulator. This placement is notably lower than the individual component percentiles would suggest — the CPU ranks in the 96th percentile among all CPUs, and the GPU in the 71st percentile among all GPUs. The disparity indicates that the RX 6600 XT is significantly holding back the 9950X3D in this particular game.

The GPU's nearest rivals in average benchmark score include the NVIDIA GeForce GTX 980 Ti (0.1% delta), AMD Radeon R9 M395X (0.4% delta), and NVIDIA GeForce RTX 3070 (-0.9% delta). The RX 6600 XT's average GPU score of 27985 places it in a performance tier that is simply not sufficient for high-refresh-rate play in a demanding simulator like Microsoft Flight Simulator at higher settings. The CPU's nearest rivals, by contrast, all score within 2.2% of the 9950X3D, showing that the processor is competitive with top-tier alternatives.

The gap between the combo's rank and the CPU's percentile suggests that pairing this processor with a more capable GPU would likely yield substantially better results. The measured FPS data supports this: even at 1080p Low, the combo only reaches 102 FPS, a figure that does not fully utilize the 9950X3D's potential based on its benchmark scores.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the measured average FPS values are: Low 102, Medium 79.6, High 58.1, and Ultra 56.1. The gap between Medium and High is 21.5 FPS, while the gap between High and Ultra is only 2 FPS, suggesting diminishing returns from High to Ultra at this resolution. The 1080p results show a clear progression where each preset step down from Low reduces performance, but the Ultra preset is only slightly worse than High.

At 2560x1440, the averages are: Low 80.3, Medium 64.7, High 44.4, and Ultra 47.7. Interestingly, the Ultra preset at 1440p (47.7 FPS) is actually higher than High (44.4 FPS), which is an anomaly in the data. The 1440p results show a 35.6 FPS difference between Low and Ultra, but the non-monotonic relationship between High and Ultra suggests either measurement variance or setting-specific optimizations.

At 3840x2160, the averages are: Low 57.4, Medium 48.1, High 36.6, and Ultra 31. The 4K results show the most consistent scaling, with each preset step producing a significant drop: Low to Medium is 9.3 FPS, Medium to High is 11.5 FPS, and High to Ultra is 5.6 FPS. The 4K Ultra result of 31 FPS is the lowest measured value across all configurations.

Across all resolutions, the Low preset provides the highest frame rates, with 1080p Low being the only configuration exceeding 100 FPS. The Ultra preset at 4K is the only configuration below 35 FPS. The data shows that this combo can deliver playable frame rates (above 30 FPS) at 4K in all presets except Ultra, and at 1440p in all presets, with 1080p providing 56-102 FPS depending on settings.

Settings Recommendations — which preset gives the best experience per the measured rows

For users targeting 60 FPS as a playability threshold, the data shows that 1080p Medium (79.6 FPS) and 1080p High (58.1 FPS) are both viable, with Medium providing a comfortable margin above 60. At 1440p, only Low (80.3 FPS) and Medium (64.7 FPS) exceed 60 FPS, while High (44.4 FPS) and Ultra (47.7 FPS) fall short. At 4K, no preset reaches 60 FPS, with Low (57.4 FPS) being the closest.

Given that the measured data shows Ultra offers only marginal gains over High at 1080p (56.1 vs 58.1 FPS) and actually underperforms High at 1440p (47.7 vs 44.4 FPS), the Ultra preset appears to provide diminishing visual returns relative to its performance cost. The High preset at 1080p delivers 58.1 FPS, which is close to the 60 FPS target, while Medium at 1080p provides a more comfortable 79.6 FPS.

For the best balance of visual quality and smooth performance, the data supports 1080p Medium as the optimal choice, offering 79.6 FPS with settings that are above Low but below the demanding High and Ultra presets. At 1440p, Medium (64.7 FPS) is the only preset that exceeds 60 FPS without dropping to Low quality, making it the recommended choice for users with 1440p displays who prioritize frame rate. At 4K, Low (57.4 FPS) is the only preset that approaches 60 FPS, but users who prefer higher visual fidelity can use Medium (48.1 FPS) or High (36.6 FPS) at the cost of smoothness. The Ultra preset is not recommended at any resolution, as it provides the lowest frame rates (31-56.1 FPS) with no consistent visual quality advantage over High in the measured data.
