Microsoft Flight Simulator

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 3080 delivers a strong, but not universal, experience in Microsoft Flight Simulator. This 12-core Zen 4 processor and Ampere-based GPU combination produces frame rates that range from comfortably playable to highly demanding, depending entirely on the resolution and quality preset you choose. The data shows that this combo is best suited for high-refresh-rate 1440p gaming or solid 4K performance when you are willing to dial back the settings from the absolute maximum.

Measured FPS Breakdown

The benchmark results for this combination reveal a clear performance hierarchy across the three tested resolutions and four quality presets. At 3840x2160 (4K), the system averages 57.1 FPS on High, 72.6 FPS on Medium, and 92.3 FPS on Low. The Ultra preset is the most demanding, pulling the average down to 53.7 FPS, which sits just below the 60 FPS playable threshold. The jump from Low to Medium costs you roughly 20 FPS, while the step from Medium to High costs another 15 FPS, indicating a steep scaling curve as graphical fidelity increases.

Moving to 2560x1440, the headroom expands significantly. The same combination produces an average of 124.5 FPS on Low, 95.7 FPS on Medium, and 72.5 FPS on High. Even the Ultra preset stays comfortably above the playable threshold at 69.5 FPS. At this resolution, the performance penalty from Low to Ultra is a substantial 55 FPS, but every preset remains fluid. At 1920x1080, the system truly stretches its legs, with the Low preset hitting a very high 156.6 FPS average. Medium follows at 122.8 FPS, High at 90.8 FPS, and Ultra still manages a robust 86.7 FPS. The data shows that 1080p is not a challenge for this hardware, even at maximum settings.

The minimum and maximum FPS values are not available in this dataset, so the analysis relies solely on the average frame rates. However, the consistency of the scaling between presets suggests a stable performance profile. The largest single drop occurs when moving from Low to Medium at 4K, which costs 19.7 FPS, while the smallest drop is from High to Ultra at 1080p, which costs only 4.1 FPS. This pattern indicates that the game becomes more GPU-bound at higher resolutions, flattening the performance difference between the top presets.

Best Settings per Resolution

For players targeting a consistent 60 FPS or higher, the optimal preset varies by resolution. At 3840x2160, the best playable setting is Medium, which delivers an average of 72.6 FPS. This provides a significant safety margin above the 60 FPS threshold, making it the recommended choice for a smooth 4K experience. The High preset at 57.1 FPS and Ultra at 53.7 FPS both fall short of this goal, so they are not recommended if frame rate stability is your priority.

At 2560x1440, the system has enough performance to run the Ultra preset at an average of 69.5 FPS. This is the most demanding preset that stays above the playable threshold, and it offers the best visual quality without sacrificing smoothness. All other presets—High, Medium, and Low—also clear the 60 FPS mark, but Ultra provides the highest fidelity while maintaining fluidity. Finally, at 1920x1080, the Ultra preset is the clear winner, averaging 86.7 FPS. This leaves ample headroom above the 60 FPS target, allowing you to enjoy maximum visual detail without any performance concerns.

CPU and GPU Roles

The performance scaling across resolutions reveals how the workload shifts between the AMD Ryzen 9 7900X and the NVIDIA GeForce RTX 3080. At 1920x1080, the frame rates are extremely high, with the Low preset reaching 156.6 FPS. This suggests that the CPU is capable of feeding the GPU at lower resolutions, where the graphics card is not the primary bottleneck. The relatively small drop from High to Ultra at 1080p (from 90.8 FPS to 86.7 FPS) indicates that the system is becoming more GPU-limited even at this resolution, but the CPU's 12 cores and 24 threads provide ample processing power for the simulation's complex physics and scenery generation.

As resolution increases to 2560x1440 and then 3840x2160, the GPU's role becomes more pronounced. The performance drop from 1080p to 4K on the Low preset is from 156.6 FPS to 92.3 FPS, a reduction of over 40%. This scaling is typical of a GPU-bound scenario, where the RTX 3080's 10 GB of GDDR6X memory and 760.3 GB/s bandwidth are taxed by the higher pixel count. The CPU's influence is still present, but the data suggests that the RTX 3080 is the limiting factor at 4K, particularly on the Ultra preset where the average falls to 53.7 FPS.

The difference between presets also highlights the CPU's strength. At 1080p, the gap between Low and Ultra is 69.9 FPS, while at 4K, the same gap is only 38.6 FPS. This compression of performance differences at higher resolutions is a classic sign of the GPU becoming the primary constraint. The Ryzen 9 7900X, with its high boost clock of 5.60 GHz and 64 MB of shared L3 cache, is clearly not the bottleneck in this configuration, even at lower resolutions where frame rates are highest.

The Verdict

This PC configuration can run Microsoft Flight Simulator, but the experience depends heavily on your display resolution and quality expectations. At 3840x2160, the system is playable only on the Low and Medium presets, with Medium being the best choice at 72.6 FPS. The High and Ultra presets fall short of the 60 FPS target, so 4K gaming requires a willingness to compromise on visual fidelity.

At 2560x1440, the verdict is unequivocal: the system runs the game smoothly on every preset. The Ultra setting averages 69.5 FPS, making it the best playable option for maximum visual quality. This is the sweet spot for this hardware, offering a balance of high detail and fluid performance. At 1920x1080, the system is more than capable, with the Ultra preset achieving 86.7 FPS. This resolution provides the greatest performance margin and is ideal for users who prioritize high frame rates over resolution. Overall, the data indicates that this combo is best suited for 1440p gaming, with 4K requiring settings adjustments and 1080p offering excellent performance.

How This Combo Ranks

In the combined benchmark database, this AMD Ryzen 9 7900X and NVIDIA GeForce RTX 3080 pairing ranks 1083rd out of 3714 tested combinations for Microsoft Flight Simulator. This places it in the top 29% of all tested systems, indicating a solidly above-average performance tier. The CPU's 91st percentile ranking among all processors and the GPU's 68th percentile ranking among all graphics cards contribute to this strong overall position.
