Microsoft Flight Simulator

Microsoft Flight Simulator is notoriously demanding, and the pairing of the AMD Ryzen 9 5900X with the NVIDIA GeForce RTX 4070 SUPER shows a clear performance curve that scales predictably with resolution. The data indicates that this combination is well-balanced for high-refresh-rate 1440p gaming but begins to lean more heavily on the GPU as pixel count increases. The measured results show a system that is capable of smooth flight in most scenarios, but the gap between settings widens significantly at 4K, revealing where the hardware’s limits lie.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial, and the pattern across all settings indicates that the RTX 4070 SUPER becomes the primary limiting factor at higher resolutions. At Low settings, the average FPS falls from 182.2 at 1920x1080 to 144.3 at 2560x1440, a decline of roughly 20.8%, and then further to 105.2 at 3840x2160, which is another 27.1% drop from the 1440p figure. This steep decline suggests that even at minimal graphical load, the GPU is being pushed harder as the render target expands.

The trend is consistent at Medium and High presets, but the percentage losses become more pronounced. At Medium, the system delivers 141.9 FPS at 1080p, 113.3 FPS at 1440p, and 82.8 FPS at 4K. The drop from 1080p to 4K here is 41.6%, which is slightly steeper than the 42.2% drop seen at Low. However, the most telling data point is at Ultra settings, where the average FPS plummets from 99.6 at 1080p to 83.5 at 1440p, and then to 56.8 at 4K. The gap between 1440p and 4K at Ultra is a 32% reduction, highlighting that the 12 GB frame buffer and the GPU’s compute resources are being saturated.

The behavior at 1080p is particularly interesting. With a 12-core, 24-thread Ryzen 9 5900X boosting up to 4.80 GHz, the CPU has ample headroom. The fact that Low settings at 1080p yields 182.2 FPS suggests that the CPU is not the bottleneck at this resolution, as the frame rate is high enough to indicate the GPU is still doing the heavy lifting. However, as resolution increases, the gap between Low and Ultra settings narrows in absolute terms, but the relative performance cost of Ultra becomes more severe, pointing to the GPU as the definitive constraint in 4K scenarios.

Settings Recommendations

Based on the measured rows, the most balanced experience for this combo is the High preset at 2560x1440, where the average FPS of 87.7 provides a smooth and visually detailed flight simulation without dipping into the lower frame rates seen at Ultra. For users prioritizing frame rate over visual fidelity, the Medium preset at 1440p, delivering 113.3 FPS, is a strong choice, offering a significant boost over High while still maintaining a respectable level of graphical detail.

At 4K, the data suggests that High settings are the practical ceiling. The 63 FPS average at 3840x2160 with High is borderline playable, but the drop to 56.8 FPS at Ultra makes the latter less appealing for a game where smooth camera panning is critical. If a user insists on 4K, Medium at 82.8 FPS is the best balance, as it provides a substantial frame rate cushion over High while avoiding the steep performance hit of Ultra. At 1080p, the system is powerful enough to run Ultra at 99.6 FPS, making it the recommended preset for users on 1080p displays who want maximum visual quality without sacrificing responsiveness.

FAQ

Q: Can this combo handle Microsoft Flight Simulator at 4K with maximum settings?

A: The measured data shows an average of 56.8 FPS at 3840x2160 with Ultra settings. While this is technically playable, it is below the 60 FPS threshold that many users prefer, indicating that Ultra at 4K is pushing the RTX 4070 SUPER to its limits.

Q: Is the Ryzen 9 5900X a bottleneck for the RTX 4070 SUPER in this game?

A: The data suggests the CPU is not a limiting factor. At 1080p Low, the system achieves 182.2 FPS, which is a very high frame rate that indicates the GPU is still the primary driver of performance. The 12-core, 24-thread processor with a 4.80 GHz boost clock provides sufficient headroom.

Q: What is the best resolution for a 144Hz monitor with this setup?

A: At 2560x1440, the Medium preset achieves 113.3 FPS, and Low reaches 144.3 FPS. High delivers 87.7 FPS. To fully utilize a 144Hz display, Low settings at 1440p are required, though Medium offers a smoother visual experience with a slight compromise on frame rate.

Q: How much of a performance hit is the Ultra preset compared to High?

A: At 1920x1080, Ultra is 6.4% slower than High (99.6 vs 106.4 FPS). At 2560x1440, the gap widens to 4.8% (83.5 vs 87.7 FPS). The most significant difference is at 4K, where Ultra is 9.8% slower than High (56.8 vs 63 FPS).

Q: Is the 12 GB of VRAM on the RTX 4070 SUPER sufficient for this game?

A: The measured FPS data indicates that the GPU performs consistently across resolutions, but the steep drop from Medium to Ultra at 4K (82.8 to 56.8 FPS) suggests that memory bandwidth and capacity are being stressed, though no explicit VRAM limitations are shown in the data.

Q: Should I lower settings to Low for competitive play?

A: This is a flight simulator, not a competitive shooter. Low settings at 1080p yield 182.2 FPS, which is excessive for the genre. The data shows that High at 1440p provides a better visual experience at 87.7 FPS, which is more than adequate for smooth flight.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, fabricated on a 7 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.80 GHz, with a total of 64 MB of L3 cache. In Microsoft Flight Simulator, which is known for its complex physics and world-streaming calculations, the CPU’s multithreaded performance is critical. The Cinebench R23 multicore score of 33150 indicates substantial processing power, which helps maintain high frame rates at lower resolutions where the GPU is not the bottleneck.

The data supports this, as the 1080p Low preset achieves 182.2 FPS, showing that the processor can feed the GPU efficiently. The single-thread performance, evidenced by a 3DMark single-thread score of 941 and a Geekbench single-core score of 2202, is also strong, which is important for the game’s primary simulation thread. However, the CPU’s role diminishes as resolution increases. The frame rate gap between 1080p and 4K at the same settings shows that the GPU becomes the limiting factor, and the CPU’s 12 cores provide enough headroom to avoid stuttering in complex scenarios. The 105 W TDP and dual-channel DDR4-3200 memory support (51.2 GB/s bandwidth) are adequate for this workload, though the data does not indicate any memory-related bottlenecks.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at performance across three resolutions and four settings presets. At 1920x1080, the system delivers 182.2 FPS on Low, 141.9 FPS on Medium, 106.4 FPS on High, and 99.6 FPS on Ultra. The scaling from Low to Ultra shows a 45.3% reduction in frame rate, indicating that the GPU is handling the increased graphical load effectively at this resolution.

Moving to 2560x1440, the averages are 144.3 FPS on Low, 113.3 FPS on Medium, 87.7 FPS on High, and 83.5 FPS on Ultra. The drop from 1080p to 1440p at each setting is consistent, with the largest absolute loss occurring on Low (37.9 FPS) and the smallest on Ultra (16.1 FPS). This suggests that the GPU is becoming more constrained at higher resolutions, but the frame rates remain playable.

At 3840x2160, the performance falls to 105.2 FPS on Low, 82.8 FPS on Medium, 63 FPS on High, and 56.8 FPS on Ultra. The transition from 1440p to 4K is significant, with the Low preset dropping by 39.1 FPS and Ultra dropping by 26.7 FPS. The data clearly shows that 4K Ultra is the most demanding scenario, and the system’s performance here is the weakest of the entire dataset. The difference between High and Ultra at 4K is only 6.2 FPS, while the difference between Medium and High is 19.8 FPS, indicating that the Ultra preset offers diminishing returns for the performance cost.
