Microsoft Flight Simulator

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 3080 Ti delivers a solid, high-refresh-rate experience in Microsoft Flight Simulator, though the data shows that the most demanding presets will push this combination to its limits at 4K. The sweet spot for this combo is the High preset, which provides a strong balance between visual fidelity and frame rate across all tested resolutions. At 1920x1080, High settings yield an average of 95.8 FPS, while 2560x1440 drops slightly to 74.9 FPS. The 4K High result of 55.1 FPS is still playable, but it is noticeably closer to the edge of smoothness. The Medium preset is a viable alternative for those prioritizing higher frame rates, delivering 127.3 FPS at 1080p, 104.4 FPS at 1440p, and 72 FPS at 4K. The Ultra preset, while visually impressive, is the most demanding, with the combo producing 89.9 FPS at 1080p, 73.9 FPS at 1440p, and only 54.6 FPS at 4K. For a consistently fluid experience, especially at higher resolutions, the data suggests that the High preset is the optimal choice, offering a significant performance uplift over Ultra with a relatively modest visual compromise.

Settings Recommendations

The measured FPS data reveals clear performance tiers across the four presets. At 1920x1080, the High preset is the clear recommendation for a 60+ FPS experience, as it averages 95.8 FPS, leaving ample headroom above the 60 FPS threshold. The Medium preset pushes this further to 127.3 FPS, which is ideal for high-refresh-rate monitors, but the visual fidelity loss may not be worth it for a sim where scenery detail matters. The Ultra preset at 89.9 FPS is still playable, but the performance gap to High is notable. Moving to 2560x1440, the High preset becomes the practical ceiling for a smooth experience at 74.9 FPS. The Medium preset offers a more comfortable margin at 104.4 FPS, while Ultra drops to 73.9 FPS, which is borderline for demanding flight scenarios. At 3840x2160, the situation tightens significantly. The High preset averages 55.1 FPS, which is playable but not ideal for fast-paced maneuvers. The Medium preset provides a more stable 72 FPS, making it the recommended choice for 4K users who want to stay above 60 FPS. The Ultra preset at 54.6 FPS is the least desirable option at this resolution, as it offers no meaningful advantage over High while costing several frames per second. The Low preset, while providing the highest frame rates (163.2 FPS at 1080p, 132 FPS at 1440p, and 95.3 FPS at 4K), sacrifices too much visual quality for a game where immersion is key, and is only suitable for competitive or diagnostic purposes.

How This Combo Ranks

This specific combination of the Ryzen 9 7900X and RTX 3080 Ti holds a rank of 482 out of 1795 tested combos in Microsoft Flight Simulator, placing it in the top 26.8% of all configurations. This is a strong showing, indicating that the pairing is well-balanced for this title. The CPU component itself is a top-tier performer, ranking in the 93rd percentile among all CPUs, with an average benchmark score of 50556. Its nearest rivals, such as the Intel Core Ultra 5 235, AMD Ryzen 9 5900XT, and Intel Core i7-13850HX, are all within a 0.8% delta, meaning the 7900X is essentially on par with the fastest processors available. The GPU, while a generation old, still holds its own, ranking in the 83rd percentile among all GPUs. Its nearest rivals, including the RTX 3090 and RTX 5070, show a performance delta of only -0.5% to -1.6%, confirming that the 3080 Ti is not a bottleneck in this setup. The combo's rank suggests that while it is not at the absolute top of the leaderboard, it delivers a very high level of performance that will satisfy most users, especially when paired with the recommended High or Medium presets.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the primary driver of frame rates in Microsoft Flight Simulator, especially at higher resolutions. The GPU's 12 GB of GDDR6X memory on a 384-bit bus provides a substantial 912.4 GB/s of bandwidth, which is crucial for streaming the vast amounts of terrain and texture data the game loads. The GA102 chip, built on an 8 nm process, contains 10240 shading units and 80 RT cores, with a boost clock of 1665 MHz. This hardware configuration allows for 34.10 TFLOPS of FP32 compute, which is sufficient to handle the game's complex rendering pipeline. The data shows that the GPU is the limiting factor at 4K, where the difference between Low and Ultra settings is a 40.7 FPS swing (from 95.3 to 54.6). This scaling is typical of a GPU-bound scenario. At 1080p, the GPU has more headroom, with the Ultra preset still achieving 89.9 FPS. The RTX 3080 Ti's performance is closely matched by the RTX 3090, which has a negligible -0.5% delta in average benchmark scores, indicating that this GPU is delivering near-flagship level performance for this generation. The card's 350 W TDP is a consideration, but the performance it delivers in this sim justifies the power draw. For users targeting 4K, the data suggests that the Medium preset is the GPU's comfortable zone, while High is achievable but with less margin for error.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this combo's performance across all settings and resolutions.

1920x1080:

• Low: 163.2 FPS
• Medium: 127.3 FPS
• High: 95.8 FPS
• Ultra: 89.9 FPS

At 1080p, the combo is rarely CPU-limited, allowing the GPU to stretch its legs. The gap between High and Ultra is a modest 5.9 FPS, suggesting that the Ultra preset's additional effects are not overly taxing at this resolution. Even the most demanding preset stays well above 60 FPS.

2560x1440:

• Low: 132 FPS
• Medium: 104.4 FPS
• High: 74.9 FPS
• Ultra: 73.9 FPS

The 1440p results show a more pronounced scaling. The jump from Medium to High costs 29.5 FPS, which is a significant drop. Interestingly, the difference between High and Ultra is only 1 FPS, making High the more efficient choice. The Low preset still offers excellent performance for high-refresh-rate displays.

3840x2160:

• Low: 95.3 FPS
• Medium: 72 FPS
• High: 55.1 FPS
• Ultra: 54.6 FPS

At 4K, the GPU becomes the clear bottleneck. The Medium preset is the only option that consistently stays above 60 FPS, with a 16.9 FPS advantage over High. The Ultra preset is nearly identical to High, at 54.6 FPS, indicating that the game's ultra settings at 4K push the GPU's memory bandwidth and compute resources to their limits.

CPU Role

The AMD Ryzen 9 7900X provides the computational backbone for this combo, and its performance characteristics are well-suited for Microsoft Flight Simulator. With 12 cores and 24 threads based on the Zen 4 architecture, the CPU offers a base clock of 4.70 GHz and a boost clock of 5.60 GHz. This high single-thread performance is critical for the simulation's core logic, which is often not perfectly parallelized. The CPU's benchmark scores reflect its strength: a Cinebench R23 single-core score of 6168 and a multi-core score of 43695 demonstrate its ability to handle both the primary simulation thread and secondary tasks like AI traffic and physics. The 64 MB of shared L3 cache helps keep frequently accessed data close to the cores, reducing memory latency. The CPU's 83.2 GB/s of DDR5 memory bandwidth is also sufficient to feed the GPU without creating a bottleneck. The data shows that at 1080p, the CPU is able to feed the GPU effectively, as evidenced by the high frame rates. However, at 4K, the GPU becomes the limiting factor, meaning the CPU still has headroom. The 7900X's ranking in the 93rd percentile of all CPUs, with an average benchmark score of 50556, places it in the top tier of processors. Its nearest rival, the Intel Core Ultra 5 235, has a delta of only -0.1%, showing that the 7900X is at the very state-of-the-art of CPU performance for this generation. This ensures that the CPU will not hold back the RTX 3080 Ti in this game, providing a stable platform for the GPU to deliver its measured FPS results.
