Microsoft Flight Simulator

Microsoft Flight Simulator with the AMD Ryzen 9 9950X3D and NVIDIA GeForce RTX 5090 produces a dataset that clearly delineates the boundaries between CPU and GPU limitation. The measured results show a combination that is exceptionally fast, yet the scaling pattern across resolutions reveals where each component takes the lead. This analysis walks through the FPS data, ranking, and settings behavior to provide a methodical breakdown of this high-end pairing.

Resolution Scaling

The FPS progression from 1080p to 4K is the primary indicator of system balance. At 1920x1080 with High settings, the combo achieves 142.1 FPS. Moving to 2560x1440 drops this to 114.9 FPS, a reduction of 19.1%. At 3840x2160, the average falls to 80.9 FPS, which is 43.1% lower than the 1080p result. This scaling shows that the RTX 5090 is still the dominant force at 1440p, but the gap narrows as resolution increases.

The Low preset tells a different story. At 1080p Low, the system hits 241.9 FPS. At 1440p Low, it reaches 193 FPS, a 20.2% drop. At 4K Low, it manages 138.4 FPS, a 42.8% decrease from 1080p. The fact that 1080p Low exceeds 240 FPS suggests the CPU is nearing its ceiling in this scenario, as the GPU has ample headroom at such low graphical loads. The 9950X3D’s 16 cores and 32 threads, with a boost clock of 5.70 GHz, are clearly capable of driving very high frame rates, but the data indicates a plateau forming beyond the 240 FPS mark.

The Ultra preset shows the most severe scaling. 1080p Ultra yields 133 FPS, 1440p Ultra drops to 107.3 FPS, and 4K Ultra falls to 79.2 FPS. The difference between 1080p and 4K at Ultra is 40.5%. This is a larger relative drop than at High, indicating that the most demanding settings amplify the GPU load disproportionately. The RTX 5090’s 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are being taxed heavily, but the 104.8 TFLOPS FP32 compute is still the limiting factor at 4K.

The data suggests that at 1080p, the CPU is the primary constraint, particularly at Low settings where the GPU is underutilized. At 4K, the GPU dominates the performance equation. The 1440p midpoint offers the best balance, with the CPU and GPU sharing the load more evenly. This is typical for a flight simulator, where draw calls and physics calculations can strain the processor, but the visual fidelity at higher resolutions invariably shifts the bottleneck to the graphics card.

Settings Recommendations

The measured data provides clear guidance on the best settings for this combo. At 4K, the High preset averages 80.9 FPS, while Ultra averages 79.2 FPS. The difference is negligible, so the High preset is the recommended choice for 4K gaming, as it offers nearly identical performance with potentially lower visual overhead. The Medium preset at 4K yields 110.3 FPS, which is a significant jump of 29.4 FPS over High. For players prioritizing frame rate over maximum visual fidelity, Medium at 4K is a strong option.

At 1440p, the High preset delivers 114.9 FPS, which is a smooth experience for most users. The Ultra preset at 1440p drops to 107.3 FPS, still playable but with a 6.6% performance penalty. The Medium preset at 1440p reaches 153.1 FPS, offering a substantial boost for competitive or high-refresh-rate displays. The Low preset at 1440p is excessive, hitting 193 FPS, which is beyond the refresh rate of most monitors and sacrifices visual quality unnecessarily.

At 1080p, the Ultra preset averages 133 FPS, which is the highest quality option that still maintains a high frame rate. The High preset at 142.1 FPS is a marginal improvement, but the Medium preset at 186.9 FPS provides a much larger performance headroom. For 1080p, the Medium or High presets are recommended, as they balance visual quality with the ability to drive high refresh rates. The Low preset at 241.9 FPS is only useful for esports-style play where maximum frame rate is paramount, but it is not necessary for this simulator.

The data suggests that the optimal experience is either High at 4K for visual fidelity or Medium at 1440p for high frame rates. The Ultra preset offers diminishing returns at all resolutions, with only a 1.7 FPS difference over High at 4K.

Measured FPS Breakdown

At 3840x2160, the measured averages are as follows: Low settings produce 138.4 FPS, Medium produces 110.3 FPS, High produces 80.9 FPS, and Ultra produces 79.2 FPS. The step from Low to Medium is a 28.1 FPS drop, while the step from Medium to High is a 29.4 FPS drop. The step from High to Ultra is only 1.7 FPS, indicating that the Ultra preset adds little computational load beyond High at this resolution.

At 2560x1440, the averages are: Low at 193 FPS, Medium at 153.1 FPS, High at 114.9 FPS, and Ultra at 107.3 FPS. The drop from Low to Medium is 39.9 FPS, and from Medium to High is 38.2 FPS. The drop from High to Ultra is 7.6 FPS, which is more pronounced than at 4K, suggesting that the Ultra preset’s effects are more noticeable at lower resolutions where the GPU has more headroom.

The drop from Medium to High is 44.8 FPS, and from High to Ultra is 9.1 FPS. The pattern here shows that each preset tier has a significant impact on performance, with the largest differences occurring at the lower settings.

The data also shows that the delta between 1080p and 4K narrows as settings increase. At Low, the 4K FPS is 42.8% lower than 1080p. At Ultra, the 4K FPS is 40.5% lower. This indicates that the GPU is the primary bottleneck at higher resolutions and settings, while the CPU becomes more relevant at lower resolutions and settings.

CPU Role

The AMD Ryzen 9 9950X3D is a 16-core, 32-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It has a base clock of 4.30 GHz and a boost clock of 5.70 GHz. The CPU features 128 MB of shared L3 cache, which is a defining characteristic of the X3D series and is particularly beneficial for gaming workloads that rely on large datasets. Its benchmark scores are impressive, with a Cinebench R23 multicore score of 59712 and a single-core score of 8430. The Geekbench multicore score is 22515, and the single-core score is 3401.

In Microsoft Flight Simulator, the CPU’s role is critical at lower resolutions and settings. The 1080p Low result of 241.9 FPS is a strong indicator that the CPU can keep up with the RTX 5090’s output. The 3DMark single-thread score of 1292 and the 2-thread score of 2549 suggest that the processor has robust per-core performance, which is essential for the simulator’s physics and AI calculations. The 16 cores and 32 threads provide ample parallel processing capability, as evidenced by the 3DMark max-threads score of 17184.

The CPU’s percentile rank of 96 versus all CPUs places it in the top tier of processors. Its nearest rival, the Intel Xeon Platinum 8270, has a 0.9% higher average score, but the in-game rank of 2nd suggests that the 9950X3D’s specific architecture is better optimized for this title. The L3 cache size of 128 MB is likely a key factor, as flight simulation involves streaming large amounts of terrain and aircraft data. The CPU’s TDP of 170 W is a consideration for cooling, but the performance data shows that it does not throttle in this scenario. The combination of high clock speeds, large cache, and multi-threading capability makes this CPU a perfect match for the RTX 5090 in this game.
