# Microsoft Flight Simulator with AMD Ryzen 5 9600X + NVIDIA GeForce RTX 5090 D

The measured data for this combination reveals a system that scales predictably with resolution but shows an interesting tension between a top-tier GPU and a mid-range 6-core CPU. At 4K Ultra, the combo delivers 84 FPS average, while dropping to 1080p Low pushes frame rates to 242 FPS. The RTX 5090 D, ranking in the 92nd percentile among all GPUs, is clearly the dominant component, but the Ryzen 5 9600X's 81st percentile CPU standing suggests potential bottlenecks at lower resolutions. The combo ranks 11th out of 2,996 tested combinations, placing it in the top 0.4% of all configurations in this game.

Resolution Scaling

The frame rate drop from 1080p to 4K tells a clear story about where the bottleneck shifts depending on resolution. At Low settings, the system produces 242 FPS at 1080p, 205 FPS at 1440p, and 151 FPS at 4K. That represents a 37.6% reduction from 1080p to 1440p, and another 26.3% reduction from 1440p to 4K. The scaling is substantial but not perfectly linear, suggesting that at 1080p Low, the CPU is likely holding back the GPU from reaching even higher frame rates.

At Ultra settings, the resolution scaling is more moderate. The system delivers 142 FPS at 1080p, 114 FPS at 1440p, and 84 FPS at 4K. The drop from 1080p to 1440p is 19.7%, and from 1440p to 4K is 26.3%. The 4K Ultra figure of 84 FPS represents a 40.8% reduction from the 1080p Ultra result. This pattern indicates that at Ultra settings, the GPU becomes increasingly the limiting factor as resolution climbs, which is expected given the massive pixel count at 3840x2160.

The Medium preset shows the most consistent scaling across resolutions. At 1080p, the average is 198 FPS; at 1440p, it drops to 159 FPS; and at 4K, it falls to 118 FPS. The percentage drops are 19.7% and 25.8% respectively. Notably, the Medium preset is the only one with recorded minimum and maximum FPS values, showing a range of 168-227 FPS at 1080p, 136-183 FPS at 1440p, and 100-135 FPS at 4K. These ranges suggest that even at Medium settings, the frame times are relatively stable, with the spread between min and max being roughly 30% of the average at each resolution.

High settings follow a similar pattern: 149 FPS at 1080p, 120 FPS at 1440p, and 88 FPS at 4K. The drop from 1080p to 1440p is 19.5%, and from 1440p to 4K is 26.7%. This consistency across High and Medium presets suggests that the game's rendering pipeline at these settings is well-balanced between CPU and GPU demands.

Settings Recommendations

Examining the measured rows, the Medium preset at 1440p appears to offer the most compelling balance for this combination. At 159 FPS average with a minimum of 136 FPS, it provides a smooth experience that stays well above typical display refresh rates. The jump from Medium to High at 1440p costs 39 FPS (from 159 to 120), which is a 24.5% performance penalty. Moving from High to Ultra at 1440p costs another 6 FPS (from 120 to 114), a smaller 5% penalty.

At 4K, the choice becomes more nuanced. The Medium preset delivers 118 FPS average with a minimum of 100 FPS, which is remarkably playable for a flight simulator at 4K resolution. The Ultra preset drops to 84 FPS, which is still serviceable but represents a 28.8% reduction from Medium. Given that the difference between Medium and Ultra at 4K is 34 FPS, users with high-refresh-rate 4K displays might prefer Medium to stay above 100 FPS consistently.

For 1080p users, the Low preset at 242 FPS seems almost superfluous unless chasing maximum frame rates for competitive scenarios, which is unusual for this genre. The Medium preset at 198 FPS with a minimum of 168 FPS provides excellent headroom. Even Ultra at 1080p maintains 142 FPS, so there is little reason to sacrifice visual quality at this resolution.

The data suggests that Medium is the sweet spot for this combo across all resolutions. At 1080p, the gap between Medium and High is 49 FPS (198 vs 149), which represents a 24.7% penalty for one step up in quality. At 1440p, that same step costs 39 FPS (24.5%), and at 4K it costs 30 FPS (25.4%). The consistency of this penalty across resolutions indicates that the Medium-to-High transition imposes a predictable rendering cost regardless of pixel count.

CPU Role

The AMD Ryzen 5 9600X brings 6 cores and 12 threads to this pairing, with a base clock of 3.90 GHz and a boost clock of 5.40 GHz. This Zen 5 architecture chip, built on TSMC's 4 nm process, has a 65 W TDP and supports DDR5 memory with dual-channel bandwidth of 89.6 GB/s. The CPU's benchmark scores show a single-thread score of 2,183.5 in Cinebench R23 and a multi-core score of 17,528.5, indicating strong per-core performance that is particularly relevant for a flight simulator that may not scale perfectly across many cores.

The CPU's percentile ranking of 81 versus all CPUs places it in the upper quintile, but its nearest rivals highlight the competitive landscape. The AMD Ryzen 7 PRO 5755GE scores nearly identically with a delta of 0.2%, while the Ryzen 7 7840H is 0.5% behind, the Ryzen 7 5800XT is 0.6% behind, and the Ryzen 7 8845HS is 0.8% behind. These rival chips all have more cores (8 vs 6), yet the 9600X holds its own in average benchmark score, suggesting that its higher boost clock and architectural efficiency compensate for fewer physical cores.

In the context of this game, the CPU's role becomes evident when examining the frame rate behavior at low resolutions. At 1080p Low, the system produces 242 FPS, which is 60.3% higher than the 151 FPS at 4K Low. If the GPU were the sole bottleneck, the scaling would be more dramatic given the 4x pixel count difference between 1080p and 4K. The relatively modest scaling at Low settings suggests that at 1080p, the Ryzen 5 9600X is approaching its limits in feeding the RTX 5090 D.

The CPU's 3DMark scores provide context: 1,253 in single-thread, 2,456 in 2-thread, 4,649 in 4-thread, 6,726 in 8-thread, and 7,590 in max-thread tests. The near-linear scaling from 2 to 4 threads (89.3% increase) and from 4 to 8 threads (44.7% increase) suggests that the CPU is well-optimized for workloads that use up to 8 threads. Microsoft Flight Simulator likely benefits from this scaling pattern, as flight simulation often involves complex physics and AI calculations that can utilize multiple threads.

How This Combo Ranks

This pairing of the Ryzen 5 9600X and RTX 5090 D achieves a rank of 11 out of 2,996 tested combos in Microsoft Flight Simulator. This places it in the top 0.37% of all configurations, which is remarkable given that the CPU is not a flagship part. The rank suggests that the RTX 5090 D's immense GPU horsepower compensates for any CPU limitations, particularly at higher resolutions where the GPU becomes the dominant factor.

The GPU's average benchmark score of 77,712 places it in the 92nd percentile among all GPUs. Its nearest rivals in the database are the AMD Radeon RX 6650M XT (1.1% ahead), AMD Radeon RX 6850M XT (1.6% behind), and two NVIDIA Tesla P100 variants (2.1% and 2.4% behind). These deltas are remarkably small, suggesting that the RTX 5090 D's performance is tightly clustered with these competitors in synthetic benchmarks, although the 5090 D's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are likely differentiators in real-world gaming.

The combo's 11th-place ranking out of 2,996 combos implies that only 10 other CPU-GPU pairings produce higher frame rates in this game. Given that the RTX 5090 D is near the top of GPU performance charts, the gap between this combo and the top 10 is likely attributable to CPUs with more cores or higher single-thread performance. The Ryzen 5 9600X's 6-core configuration may be the limiting factor preventing this combo from reaching the absolute top ranks.

GPU Role

The NVIDIA GeForce RTX 5090 D is a formidable GPU by any measure. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is crucial for a flight simulator that may stream large terrain and scenery data. The GPU's 21,760 shading units, 680 texture mapping units, and 176 render output units are backed by 170 ray tracing cores and 680 tensor cores, all running at a boost clock of 2,407 MHz.

The GPU's FP32 performance of 104.8 TFLOPS and texture rate of 1,636.8 GTexel/s indicate massive compute capabilities. With a 575 W TDP and a suggested 950 W PSU, this is a power-hungry component that demands serious system support. The GPU's 92nd percentile ranking among all GPUs places it comfortably in the top tier, and its benchmark scores reflect this: 44,065 in Passmark G3D, 31,0674 in Geekbench OpenCL, and 376,915 in Geekbench Vulkan.

In this game, the GPU's role becomes more pronounced as resolution increases. At 4K Ultra, the combo produces 84 FPS, which is a 40.8% reduction from the 1080p Ultra result of 142 FPS. This significant drop at 4K Ultra suggests that the GPU is being heavily taxed by the combination of high resolution and high-quality settings. The fact that the 4K Ultra result (84 FPS) is only modestly below the 4K High result (88 FPS) indicates that the Ultra preset's additional effects are not disproportionately expensive at 4K.

The GPU's memory capacity of 32 GB is noteworthy for a flight simulator, which often requires loading large world areas. The measured frame rates suggest that memory bandwidth is not a bottleneck, as the system maintains playable performance even at 4K Ultra. The GPU's PCIe 5.0 x16 interface ensures that data transfer between CPU and GPU is not a limiting factor, even with the Ryzen 5 9600X's Gen 5 support.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all settings. The Low preset achieves 242 FPS average, while Medium reaches 198 FPS with a range of 168-227 FPS. High delivers 149 FPS, and Ultra maintains 142 FPS. The gap between Low and Medium is 44 FPS (18.2%), between Medium and High is 49 FPS (24.7%), and between High and Ultra is only 7 FPS (4.7%). This compression between High and Ultra at 1080p suggests that the CPU may be limiting performance at this resolution, as the additional GPU workload from Ultra settings has minimal impact.

At 2560x1440, the frame rates scale down proportionally. Low produces 205 FPS, Medium delivers 159 FPS with a range of 136-183 FPS, High achieves 120 FPS, and Ultra drops to 114 FPS. The percentage gaps are 22.4% (Low to Medium), 24.5% (Medium to High), and 5% (High to Ultra). The consistency of these gaps with the 1080p results indicates that the game's settings scaling is resolution-independent in relative terms.

At 3840x2160, the system delivers 151 FPS at Low, 118 FPS at Medium (range 100-135 FPS), 88 FPS at High, and 84 FPS at Ultra. The gap between Low and Medium is 33 FPS (21.9%), between Medium and High is 30 FPS (25.4%), and between High and Ultra is only 4 FPS (4.5%). The High-to-Ultra gap at 4K is the smallest in absolute terms, suggesting that the Ultra preset's incremental quality features are relatively cheap at this resolution.

The Medium preset's minimum FPS figures provide insight into frame pacing. At 1080p, the minimum is 168 FPS (84.8% of average); at 1440p, the minimum is 136 FPS (85.5% of average); and at 4K, the minimum is 100 FPS (84.7% of average). The consistency of this ratio across resolutions indicates stable frame delivery regardless of pixel count.
