# Microsoft Flight Simulator — AMD Ryzen 7 9850X3D + NVIDIA GeForce RTX 5090 D

This combo ranks 4th out of 2,996 tested configurations in Microsoft Flight Simulator, placing it in the top 0.13% of all systems measured. The pairing of AMD's 8-core Zen 5 flagship with NVIDIA's GB202-based Blackwell 2.0 flagship produces a system that delivers playable frame rates even at 4K Ultra, with the data showing a clear CPU-bound pattern at lower resolutions and a GPU-bound pattern at 4K. The measured results across 12 resolution/settings combinations reveal a platform that excels in this simulation title, though the scaling behavior between presets and resolutions tells a nuanced story about where the performance ceiling actually sits.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 9850X3D is an 8-core, 16-thread processor built on the Zen 5 architecture with the Granite Ridge codename. It operates at a base clock of 4.70 GHz and boosts to 5.60 GHz, with a 120 W TDP. The processor features 96 MB of shared L3 cache, which is substantial for a desktop part, and each core carries 80 KB of L1 and 1 MB of L2 cache. This cache hierarchy is particularly relevant for Microsoft Flight Simulator, a title that streams terrain and scenery data continuously, making cache capacity a meaningful factor in frame pacing.

The CPU's benchmark profile shows strong multi-threaded and single-threaded performance. In Cinebench R23, it scores 22,807 multi-core and 2,228 single-core. The PassMark multi-thread score is 41,318, and single-thread is 4,704. Data compression in PassMark hits 474,501, while floating-point math reaches 81,998 and integer math reaches 123,140. These synthetic scores position the processor at the 92nd percentile among all CPUs, with an average benchmark score of 58,386. Its nearest rivals include the Intel Xeon Platinum 8260M at 58,323 (0.1% slower), the Intel Xeon w5-2545 at 58,504 (0.2% faster), the Intel Core i9-14900 at 58,115 (0.5% slower), and the AMD Ryzen AI 9 HX 470 at 58,826 (0.7% faster). The delta between the best and worst of these rivals is less than 1.5%, indicating the 9850X3D sits in a tightly contested performance band for general compute.

In the context of this game, the measured FPS data shows that at 1080p Low, the combo achieves 250 FPS average, which strongly suggests the CPU and GPU are both capable of far exceeding display refresh rates. At 1080p Ultra, the average drops to 142 FPS, a 43% reduction from Low. This drop is primarily driven by increased GPU workload, but the fact that 1080p Ultra still clears 140 FPS indicates the CPU is not the limiting factor at this resolution. The 8-core, 16-thread configuration with high boost clocks appears well-suited to the simulation's single-thread-heavy rendering loop, while the generous L3 cache helps with the asset streaming that characterizes this title.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured data includes four presets at each of three resolutions: Low, Medium, High, and Ultra. At 1080p, the Medium preset delivers 198 FPS average with a min of 168 and max of 227. The High preset at 1080p delivers 149 FPS average, and Ultra delivers 142 FPS. The gap between Medium and High is 49 FPS, while the gap between High and Ultra is only 7 FPS. This suggests that the visual fidelity gains from High to Ultra come at a relatively modest performance cost at 1080p, but the jump from Medium to High is substantial.

At 1440p, Medium delivers 159 FPS (min 136, max 183), High delivers 120 FPS, and Ultra delivers 114 FPS. The Medium-to-High drop is 39 FPS, while High-to-Ultra is only 6 FPS. At 4K, Medium delivers 118 FPS (min 100, max 135), High delivers 88 FPS, and Ultra delivers 84 FPS. The Medium-to-High drop is 30 FPS, and High-to-Ultra is 4 FPS.

The data shows a consistent pattern: the performance difference between High and Ultra is small across all resolutions (4-7 FPS), while the difference between Medium and High is large (30-49 FPS). For users seeking the best balance of visual quality and frame rate, the High preset appears to be the sweet spot, as it captures most of the visual uplift from Ultra at a fraction of the cost. The Ultra preset's additional overhead does not translate into proportionally better frame rates, making it a poor trade for the measured performance. Medium remains viable for users prioritizing frame rate, especially at 4K where it delivers 118 FPS versus 88 FPS on High — a 34% improvement.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data across resolutions reveals the scaling behavior of this combo. At Low settings, the average FPS drops from 250 at 1080p to 205 at 1440p (an 18% reduction) and then to 151 at 4K (a 40% reduction from 1080p). At High settings, the average drops from 149 at 1080p to 120 at 1440p (19% reduction) and then to 88 at 4K (41% reduction from 1080p). At Ultra settings, the average drops from 142 at 1080p to 114 at 1440p (20% reduction) and then to 84 at 4K (41% reduction from 1080p).

The consistency of these percentage drops across different settings presets is notable. Whether running Low or Ultra, the transition from 1080p to 1440p costs roughly 18-20% of performance, and the transition from 1080p to 4K costs roughly 40-41%. This uniform scaling pattern indicates that the GPU is becoming the primary limiting factor as resolution increases, regardless of the settings preset. If the CPU were the bottleneck, we would expect to see smaller FPS drops at higher resolutions, because the GPU would be doing more work per frame while the CPU workload remains relatively constant.

The fact that 1080p Low hits 250 FPS suggests the CPU is capable of feeding the GPU at extremely high frame rates. The 4K Low result of 151 FPS shows that even at the lowest settings, the GPU workload at 4K is substantial enough to bring the frame rate down by 40%. This is consistent with a GPU-bound scenario at 4K, where the RTX 5090 D's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are being utilized heavily. The data indicates that at 1080p, the system is likely CPU-bound or balanced, while at 4K, the GPU is clearly the limiting component.

These deltas are small, suggesting the 5090 D is in a competitive performance tier for general GPU workloads.

For Microsoft Flight Simulator specifically, the GPU's role is evident in the resolution scaling data. At 4K, the average FPS ranges from 84 on Ultra to 151 on Low, showing that the GPU's workload at this resolution dominates the frame time budget. The 32 GB VRAM is particularly relevant for a flight simulator that loads extensive scenery, airport detail, and aircraft models — the capacity likely prevents texture streaming bottlenecks that could cause stutters. The 1.79 TB/s bandwidth ensures that large texture sets can be moved quickly, which is critical when flying over dense urban areas or detailed terrain. The GPU's high boost clock of 2407 MHz contributes to the raw compute throughput needed for the simulation's rendering pipeline, including draw calls for complex 3D environments.
