# Microsoft Flight Simulator with AMD Ryzen 9 9900X3D + NVIDIA GeForce RTX 5090 D

The AMD Ryzen 9 9900X3D paired with the NVIDIA GeForce RTX 5090 D delivers a compelling performance profile in Microsoft Flight Simulator, a title known for its demanding rendering of vast landscapes and complex avionics. The measured data reveals a system that excels at high refresh rates across all tested resolutions, with the combination ranking 10th out of 2,996 tested combos — placing it in the top 0.3% of all configurations. This pairing of a 12-core Zen 5 processor with a Blackwell 2.0 GPU produces frame rates that range from a playable 84 FPS at 4K Ultra to an exceptionally smooth 245 FPS at 1080p Low, demonstrating headroom for both visual fidelity and competitive frame pacing. The following analysis breaks down how resolution scaling, CPU characteristics, and GPU capabilities each contribute to the overall experience, drawing exclusively from the measured benchmark data.

Resolution Scaling

The frame rate progression across resolutions tells a clear story about where the bottleneck shifts in this system. At 1080p High, the combo produces 149 FPS, while 1440p High yields 120 FPS — a drop of 19.5%. Moving from 1440p to 4K High, the frame rate falls from 120 FPS to 88 FPS, a reduction of 26.7%. This pattern indicates that the GPU becomes progressively more stressed as pixel count increases, but the CPU remains capable of feeding the graphics card even at the highest resolution.

The Low settings preset reveals the purest measure of CPU-bound performance. At 1080p Low, the system hits 245 FPS, which drops to 205 FPS at 1440p Low (a 16.3% decrease) and then to 151 FPS at 4K Low (a 26.3% decrease from 1440p). The fact that even at 4K Low the system maintains 151 FPS suggests that the Ryzen 9 9900X3D's 12 cores and 24 threads are providing ample processing power, with the RTX 5090 D's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth handling the increased memory demands of higher resolutions without severe penalties.

The Medium preset, which includes min and max FPS data, offers additional insight into frame consistency. At 1080p Medium, the average is 198 FPS with a range of 168-227 FPS (a spread of 59 FPS). At 1440p Medium, the average drops to 159 FPS with a range of 136-183 FPS (a 47 FPS spread). At 4K Medium, the average falls to 118 FPS with a range of 100-135 FPS (a 35 FPS spread). Interestingly, the frame range narrows as resolution increases, suggesting that at higher resolutions, the GPU's workload becomes more consistent, reducing the variability that can occur when the CPU occasionally becomes the limiting factor at lower resolutions.

The Ultra preset shows the most dramatic scaling. From 142 FPS at 1080p to 114 FPS at 1440p (a 19.7% drop) and then to 84 FPS at 4K (a 26.3% drop from 1440p). The 4K Ultra result of 84 FPS is the lowest measured value in the entire dataset, yet it remains perfectly playable for a flight simulator where precision matters more than twitch reflexes. The scaling from 1080p to 4K Ultra represents a total reduction of 40.8%, which is moderate compared to what might be expected from a less capable GPU — this suggests that the RTX 5090 D's substantial compute resources, including 21,760 shading units and 176 ROPs, are being utilized effectively across all settings.

CPU Role

The AMD Ryzen 9 9900X3D brings 12 cores and 24 threads based on the Zen 5 architecture, codenamed Granite Ridge, manufactured on TSMC's 4 nm process. With a base clock of 4.40 GHz and boost clock of 5.50 GHz, this processor is designed for high single-thread performance, which is critical for flight simulators that often rely heavily on a few primary threads for physics and flight model calculations. The 128 MB of L3 cache is particularly advantageous for this workload, as flight simulator data sets — including terrain tiles and airport scenery — can be large enough to benefit from the ample cache hierarchy.

Benchmark data shows the CPU's multithreaded strength: Cinebench R23 multicore scores 47,737, while single-core scores 6,739. The Geekbench results show 22,884 multicore and 3,041 single-core. In PassMark, multithread performance reaches 56,154, with single-thread at 4,646. The 3DMark tests reveal scaling from 2,512 for 2 threads to 13,795 for max threads, indicating good thread scaling that benefits the multiple subsystems running concurrently in Microsoft Flight Simulator — weather simulation, AI traffic, and rendering threads can all distribute across the 24 threads.

The CPU's percentile ranking against all processors is 91, placing it in the top 9% of all CPUs tested. Its nearest rival, the Intel Core Ultra 5 245KF, scores 55,093 on average, which is 0.6% higher than the 9900X3D's average benchmark score of 54,762. However, the 9900X3D outperforms the Intel Core Ultra 5 245K by 1.3% (54,053) and the Intel Xeon 6505P by 2% (53,701). These deltas are small, indicating that in synthetic benchmarks, the 9900X3D is competitive with — but not dramatically superior to — its closest Intel counterparts. In actual game performance, the CPU's contribution is evident in the high frame rates at lower resolutions where the GPU is less stressed, allowing the processor to demonstrate its capability to drive 245 FPS at 1080p Low.

How This Combo Ranks

The combo rank of 10th out of 2,996 tested combinations places this system in an elite tier. This ranking is particularly notable given the diverse range of hardware combinations tested — from budget CPUs paired with integrated graphics to flagship processors with top-tier GPUs. Being in the top 10 means that only nine other CPU-GPU pairings produced higher average frame rates in Microsoft Flight Simulator.

The CPU's percentile ranking of 91 (top 9% of all CPUs) and the GPU's percentile ranking of 92 (top 8% of all GPUs) are closely matched, suggesting that neither component is dramatically over- or under-powered relative to the other. This balance is reflected in the measured frame rates, which show no obvious signs of severe bottlenecking at any resolution. The CPU's nearest rival, the Intel Core Ultra 5 245KF, has a marginally higher average benchmark score (55,093 vs 54,762), yet the overall combo ranking demonstrates that the 9900X3D's specific characteristics — including its large L3 cache — may be more beneficial for this particular game than raw synthetic scores suggest.

The GPU's nearest rivals include the AMD Radeon RX 6650M XT (1.1% higher average score) and the AMD Radeon RX 6850M XT (1.6% lower), indicating that the RTX 5090 D sits in a competitive performance tier. However, these rival comparisons are based on synthetic benchmarks, and the measured in-game results show that the 5090 D's real-world performance in flight simulation is exceptional, as evidenced by the high frame rates even at 4K Ultra.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all settings. The Low preset leads with 245 FPS average, followed by Medium at 198 FPS (with a range of 168-227 FPS), High at 149 FPS, and Ultra at 142 FPS. The difference between Low and Ultra is 103 FPS, indicating that the more demanding graphical features in the Ultra preset reduce performance by 42% compared to Low.

Moving to 2560x1440, the frame rates remain high but show the expected reduction from pixel count increases. Low settings yield 205 FPS, Medium produces 159 FPS (136-183 FPS range), High achieves 120 FPS, and Ultra delivers 114 FPS. The gap between Low and Ultra narrows to 91 FPS, representing a 44.4% reduction from Low to Ultra. The Medium preset's frame range of 136-183 FPS (a 47 FPS spread) indicates good consistency with only moderate variance during complex scenes.

At 3840x2160, the highest resolution tested, the system maintains playable frame rates across all settings. Low produces 151 FPS, Medium delivers 118 FPS (100-135 FPS range), High achieves 88 FPS, and Ultra drops to 84 FPS. The Medium preset's range of 100-135 FPS (a 35 FPS spread) is the tightest of any resolution, suggesting that at 4K, the workload is more evenly distributed and frame times are more stable. The jump from 4K High (88 FPS) to 4K Ultra (84 FPS) is only 4 FPS, indicating that the Ultra preset's additional features at 4K are relatively inexpensive in performance terms.

The data shows a consistent pattern: at each resolution, the Low preset provides the highest frame rates, with Medium offering a substantial step up in visual quality for a moderate performance cost. High and Ultra are closer together, with Ultra providing diminishing returns over High at 4K.

Settings Recommendations

For players prioritizing smoothness and responsiveness, the Low preset at 1440p provides 205 FPS, which is far beyond what any standard monitor can display. Even at 4K, Low yields 151 FPS, making this a viable option for high-refresh 4K displays. However, flight simulators benefit from visual clarity for navigation and scenery appreciation, so the Low preset may be unnecessarily restrictive.

The Medium preset at 1440p offers the best balance in the measured data. At 159 FPS average with a minimum of 136 FPS, it provides a comfortable margin above 120 FPS, ensuring smooth frame delivery even during complex scenes. The 4K Medium result of 118 FPS is also strong, though the minimum of 100 FPS means there may be brief dips below the 120 FPS threshold. For players with high-refresh 1440p monitors, Medium at 1440p is the recommended starting point.

The High preset at 1440p (120 FPS) and 4K (88 FPS) provides a significant visual improvement over Medium. At 1440p, 120 FPS is sufficient for most monitors, and the visual upgrade from Medium to High is noticeable in shadow quality and texture detail. At 4K, the 88 FPS result is still smooth for a flight simulator, where frame rates above 60 FPS are generally adequate. The Ultra preset at 1440p (114 FPS) or 4K (84 FPS) delivers the maximum visual quality, and the small performance gap between High and Ultra at 4K (only 4 FPS) makes Ultra the better choice at that resolution for those who want the best visuals.

GPU Role

The NVIDIA GeForce RTX 5090 D is a formidable graphics card based on the Blackwell 2.0 architecture, featuring the GB202 chip manufactured on TSMC's 5 nm process. With 21,760 shading units, 680 texture mapping units, and 176 ROPs, it provides substantial raw compute power. The 32 GB of GDDR7 memory on a 512-bit bus delivers 1.79 TB/s of bandwidth, which is crucial for flight simulator's large textures and complex scenery data. The boost clock of 2,407 MHz and base clock of 2,017 MHz allow the card to maintain high throughput under sustained load.

The GPU's memory capacity is a significant advantage for Microsoft Flight Simulator, which can load extensive terrain and aircraft data into VRAM. The 32 GB allocation ensures that even at 4K Ultra settings, the system never approaches memory limits, avoiding potential stuttering from texture swapping. The 104.8 TFLOPS of FP32 compute provides the arithmetic capability needed for the game's lighting calculations and shadow rendering.

The GPU's percentile ranking of 92 against all GPUs places it in the top 8% of graphics cards tested. Its nearest rivals in synthetic benchmarks include the AMD Radeon RX 6650M XT (1.1% higher average score of 76,904 vs 77,712) and the AMD Radeon RX 6850M XT (1.6% lower at 78,940). However, these are mobile GPUs that would not be expected to compete with a desktop flagship, and the in-game results demonstrate the 5090 D's dominance in real-world flight simulation performance.

The scaling from 1080p to 4K shows the GPU's capability to handle increasing pixel loads. At Ultra settings, the frame rate drops from 142 FPS at 1080p to 84 FPS at 4K, a 40.8% reduction. This is a moderate scaling penalty that indicates good GPU utilization — some less capable cards see drops of 50% or more. The RTX 5090 D's high bandwidth and compute resources allow it to maintain reasonable frame rates even at the most demanding settings, though the data suggests that 4K Ultra is the point where the GPU's workload becomes the primary limiting factor in this system.
