Microsoft Flight Simulator

Microsoft Flight Simulator with the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 5090 D delivers a benchmark result that places this combination at rank 61 out of 2996 tested configurations, putting it in the top 2% of all recorded pairings. The data set, which spans three resolutions and four quality presets, reveals a system that is overwhelmingly GPU-bound at higher settings but begins to show its CPU pedigree as resolution drops and frame rates climb toward the triple digits.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases, though the magnitude of the drop varies significantly by settings preset. At High settings, the average frame rate falls from 149 FPS at 1920x1080 to 120 FPS at 2560x1440, a 19.5% reduction, and then further to 88 FPS at 3840x2160, representing a 41% total drop from the 1080p baseline. This steep decline indicates that the RTX 5090 D's rendering workload at 4K is substantial enough that even this flagship GPU becomes the limiting factor, with the CPU having ample headroom to feed it.

The Ultra preset tells a similar story but with a compressed range. The 142 FPS at 1080p falls to 114 FPS at 1440p, then to 84 FPS at 4K, a 40.8% total reduction. Interestingly, the delta between High and Ultra at 1080p is only 7 FPS (149 vs 142), but at 4K that gap widens to just 4 FPS (88 vs 84), suggesting that the Ultra preset's additional effects are largely GPU-bound and the card handles them with consistent efficiency across resolutions.

Low settings reveal the most extreme resolution scaling, with 183 FPS at 1080p dropping to 170 FPS at 1440p and then to 151 FPS at 4K. The 17.5% drop from 1080p to 4K at Low is the smallest of any preset, indicating that at these settings the system is approaching a more balanced state where both CPU and GPU contribute. The Medium preset sits between extremes, with 167 FPS at 1080p, 156 FPS at 1440p, and 118 FPS at 4K, showing a 29.3% total decrease.

What the data makes clear is that the RTX 5090 D is the dominant bottleneck at 4K Ultra, where 84 FPS represents a 40.8% shortfall versus the 1080p result. In contrast, the 1080p Low result of 183 FPS suggests that the Ryzen 9 5900X's 12 cores and 24 threads are capable of driving frame rates that approach the practical limits of the simulation engine, making further resolution reductions yield diminishing returns.

CPU Role

The AMD Ryzen 9 5900X, built on the Zen 3 architecture with a 7 nm process, provides 12 cores and 24 threads with a base clock of 3.70 GHz and a boost clock of 4.80 GHz. In synthetic benchmarks, this processor achieves a single-thread score of 941 in 3DMark and 1527 in Cinebench R23, while multi-threaded scores reach 10075 in 3DMark max threads and 16262 in Cinebench R23 multicore. These numbers indicate strong per-core performance, which is critical for a flight simulator that relies heavily on the main simulation thread.

The CPU's benchmark percentile of 87 versus all CPUs, with an average benchmark score of 41376, places it in the upper echelon of desktop processors. Its nearest rivals include the Intel Core Ultra 7 366H at a 0.3% higher score, the Intel Core Ultra 7 356H at 0.4% higher, the AMD Ryzen AI 5 PRO 440 at 0.4% higher, and the Intel Core i7-14650HX at 0.5% lower. This tight clustering suggests that the 5900X's performance is well within the expected range for modern high-end CPUs, though it does not lead the pack.

In the context of Microsoft Flight Simulator, the CPU's role becomes evident when examining the 1080p Low result of 183 FPS. At these settings, the GPU is underutilized, and the frame rate is likely constrained by the CPU's ability to process the simulation's physics, weather, and terrain systems. The 12-core configuration helps maintain consistent frame pacing, as evidenced by the Medium preset's minimum FPS of 142 at 1080p, which represents a 85% retention of the average 167 FPS. The L3 cache of 64 MB is substantial and aids in keeping frequently accessed simulation data close to the cores, reducing memory latency that could otherwise cause stutters.

The processor's memory bandwidth of 51.2 GB/s over a dual-channel DDR4 interface is modest by modern standards, but the benchmark results show that it is sufficient for this workload. The 3DMark 16-thread score of 9075 and max-thread score of 10075 demonstrate that scaling beyond 8 threads provides a 52.6% improvement, indicating that the simulation can leverage multiple cores effectively, though the single-thread score of 941 remains the more critical metric for frame generation.

The NVIDIA GeForce RTX 5090 D, built on the Blackwell 2.0 architecture with a 5 nm process, is a formidable graphics card with 32 GB of GDDR7 memory on a 512-bit bus, yielding a bandwidth of 1.79 TB/s. Its boost clock of 2407 MHz and 21760 shading units contribute to a FP32 compute rating of 104.8 TFLOPS, positioning it as one of the most powerful consumer GPUs available. The card's benchmark percentile of 92 versus all GPUs, with an average score of 77712, places it well above the median, though its nearest rivals in the database are surprisingly mid-range mobile parts.

The nearest rival, the AMD Radeon RX 6650M XT, scores 76904 for a 1.1% lower result, while the AMD Radeon RX 6850M XT scores 78940 for a 1.6% higher result. The NVIDIA Tesla P100 PCIe 12 GB and 16 GB variants score 79396 and 79605 respectively, representing 2.1% and 2.4% advantages. This clustering suggests that the 5090 D's benchmark score, while high, does not fully capture its real-world capabilities in this specific title, where the measured FPS data demonstrates exceptional performance.

In Microsoft Flight Simulator, the GPU's role is most apparent at 4K resolution, where the average frame rates of 84-88 FPS at High and Ultra settings indicate that the card is working near its limits. The 32 GB VRAM capacity provides ample headroom for the game's high-resolution textures and complex scenery, and the 1.79 TB/s bandwidth ensures that texture streaming does not become a bottleneck. The 680 TMUs and 176 ROPs, combined with a texture rate of 1636.8 GTexel/s and pixel rate of 423.6 GPixel/s, allow the card to handle the dense geometry and lighting calculations typical of flight simulation environments.

The GPU's performance at lower settings further illustrates its capabilities. At 1080p Low, the 183 FPS result suggests that the card is far from saturated, and the 151 FPS at 4K Low indicates that even at high resolution, the GPU can deliver smooth frame rates when visual effects are minimized. The RTX 5090 D's support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 ensures compatibility with the game's rendering pipeline, and its PCIe 5.0 x16 interface provides sufficient bandwidth for data transfer from the CPU.

Settings Recommendations

The measured FPS data provides clear guidance for optimizing the experience with this hardware combination. For users prioritizing maximum frame rates, the Low preset at 1080p delivers 183 FPS, which is more than sufficient for any display and provides the smoothest possible simulation. However, this comes at the cost of visual fidelity, which may be undesirable in a game where scenery and weather are central to the experience.

The Medium preset emerges as the sweet spot across all resolutions. At 1080p, it delivers 167 FPS with a minimum of 142, providing a 85% frame retention that ensures smooth playback. At 1440p, the Medium preset achieves 156 FPS with a minimum of 132, which is ideal for high-refresh-rate monitors. Even at 4K, the Medium preset's 118 FPS average and 100 FPS minimum are respectable, offering a playable experience without requiring significant quality compromises.

For users with 4K displays who demand the highest visual quality, the High preset at 88 FPS is the best choice, as it provides a 4.8% improvement over Ultra's 84 FPS while likely offering nearly identical visual output. The Ultra preset's 84 FPS at 4K is the only scenario where the frame rate drops below 85, and the 40.8% reduction from 1080p Ultra makes it the least efficient setting for this resolution. At 1440p, the High preset's 120 FPS is a strong alternative to Ultra's 114 FPS, with the same 5.3% performance advantage.

The data suggests that the Medium preset offers the most consistent experience, with the minimum FPS remaining above 100 even at 4K. This consistency is critical in a flight simulator, where frame drops can disrupt the sense of immersion and make precise control difficult. The High preset provides a good balance for users who prioritize visual quality over maximum frame rates, while the Low preset is best reserved for competitive or analytical use where frame rate is paramount.
