# Microsoft Flight Simulator with Intel Core Ultra 9 185H + NVIDIA GeForce RTX 5090

This combination of the Intel Core Ultra 9 185H and NVIDIA GeForce RTX 5090 delivers playable performance across all tested settings in Microsoft Flight Simulator, with the data showing a clear pattern: the RTX 5090's massive GPU resources dominate at higher resolutions, while the CPU's 16 cores and 22 threads become more relevant at lower settings where frame rates exceed 170 FPS. The measured results place this combo at rank 586 out of 2,996 tested combinations, putting it in the top 20% of all systems evaluated for this flight simulator.

Settings Recommendations

The measured FPS data reveals distinct tiers of performance across the four settings presets. At 1080p, the Low preset delivers an average of 173 FPS, which drops to 135 FPS at Medium, 101 FPS at High, and 96 FPS at Ultra. The gap between Low and Medium is 38 FPS, while the gap between High and Ultra is only 5 FPS, suggesting diminishing returns at the top end. For users prioritizing smoothness over visual fidelity, the Medium preset at 1080p offers 135 FPS average with a minimum of 114 FPS and maximum of 155 FPS, providing a substantial cushion above the 60 FPS threshold.

At 1440p, the Medium preset achieves 109 FPS average with a minimum of 92 FPS, which remains well within playable territory. The High preset delivers 82 FPS, while Ultra drops to 78 FPS. The data indicates that Medium at 1440p is the sweet spot for balancing visual quality and performance, as it maintains frame rates above 90 FPS even in demanding scenes. The 4K results show a different story: Medium averages 80 FPS with a minimum of 68 FPS, while High averages 60 FPS exactly, and Ultra drops to 57 FPS. The Ultra preset at 4K falls below the 60 FPS threshold, making it less desirable for consistent smoothness.

The measured data suggests that the Medium preset provides the most consistent experience across all resolutions. At 1080p Medium, the min-to-max range spans 114-155 FPS, a 41 FPS spread that indicates reasonable frame pacing. At 1440p Medium, the range narrows to 92-125 FPS, a 33 FPS spread. At 4K Medium, the range is 68-92 FPS, a 24 FPS spread. This tightening of the frame time distribution at higher resolutions suggests that the system becomes more GPU-bound as resolution increases, which aligns with the RTX 5090's architecture.

For users with 4K displays, the High preset at 60 FPS average represents the minimum acceptable experience, while Medium at 80 FPS provides better headroom. The Ultra preset at 4K, averaging 57 FPS, is the only tested configuration that dips below 60 FPS, making it the least recommended option. The data implies that Medium settings offer the best balance of visual quality and performance headroom across all three resolutions, with the added benefit of consistent minimum frame rates that never drop below 68 FPS even at 4K.

CPU Role

The Intel Core Ultra 9 185H brings 16 cores and 22 threads to this configuration, with a base clock of 3.90 GHz and boost clock of 5.10 GHz. The CPU's benchmark results show a Cinebench R23 multi-core score of 17,984.5 and single-core score of 1,810.5, placing it in the 85th percentile of all CPUs tested. Its nearest rivals in aggregate performance include the AMD Ryzen AI 7 PRO 350 at -0.1% delta, Intel Core 7 250H at -0.2%, AMD Ryzen 7 PRO 5845 at -0.4%, and AMD Ryzen 7 7700X at -0.7%, indicating this chip sits in a tightly clustered performance band.

In Microsoft Flight Simulator, the CPU's role becomes evident when examining the scaling from 1440p to 1080p. At High settings, the jump from 82 FPS at 1440p to 101 FPS at 1080p represents a 23.2% increase, while the jump from 4K High at 60 FPS to 1440p High at 82 FPS represents a 36.7% increase. This asymmetry suggests that the CPU begins to limit performance at 1080p, where the GPU has less work to do. The Geekbench multi-core score of 11,657 and single-core score of 1,794 support this interpretation, as flight simulator physics and AI calculations benefit from strong single-thread performance.

The PassMark physics score of 1,956 and single-thread score of 3,697 provide additional context. The physics score, which measures the CPU's ability to handle real-time calculations, is particularly relevant for a flight simulator that must process aerodynamics, weather, and terrain interactions. The data compression score of 339,489 and integer math score of 98,302 suggest robust general-purpose computing capability, though these are less directly tied to gaming performance than the Cinebench or Geekbench results.

The CPU's 24 MB of shared L3 cache and 2 MB per-core L2 cache contribute to its ability to feed data to the GPU efficiently. With a memory bandwidth of 89.6 GB/s over dual-channel DDR5, the CPU can sustain high data throughput, which matters in a game that streams terrain and scenery data continuously. The 45W TDP indicates this is a mobile-oriented chip, yet it still manages to keep pace with desktop rivals like the Ryzen 7 7700X within 0.7% in aggregate benchmarks, suggesting that thermal constraints are not severely hampering its performance in this testing scenario.

How This Combo Ranks

The combo rank of 586 out of 2,996 tested combinations places this system in the 80.4th percentile of all tested configurations for Microsoft Flight Simulator. This ranking reflects the combination of the Intel Core Ultra 9 185H and NVIDIA GeForce RTX 5090 working together. The CPU's 85th percentile ranking among all CPUs and the GPU's 92nd percentile among all GPUs suggest that the GPU is the stronger component in this pairing, yet the overall combo ranking falls below both individual percentiles, indicating potential bottlenecking or game-specific optimization factors.

The delta between the CPU's percentile (85th) and the combo's percentile (80.4th) suggests that the CPU's performance is slightly less impactful in this game than in general-purpose benchmarks. Conversely, the GPU's 92nd percentile ranking is also not fully translated into the combo's 80.4th percentile, implying that the RTX 5090's capabilities are not fully utilized at lower resolutions where the CPU becomes the limiting factor. At 4K, however, the data shows the GPU is clearly the dominant component, with the Ultra setting delivering 57 FPS and High delivering 60 FPS, both of which are close to what one would expect from a top-tier GPU.

The rank of 586 means there are 585 configurations that perform better in this specific game, which is a notable achievement given the 2,996 total combos tested. This places the system in the top fifth of all tested configurations, a position that reflects the high-end nature of both components. The fact that the rank is not higher despite the GPU's strong benchmark scores suggests that Microsoft Flight Simulator's engine places significant demands on CPU performance, particularly at lower resolutions where the GPU has spare capacity.

Resolution Scaling

The measured FPS data reveals distinct scaling patterns as resolution increases from 1080p to 4K. At Low settings, the average FPS drops from 173 at 1080p to 139 at 1440p (a 19.7% decrease) and further to 103 at 4K (a 25.9% decrease from 1440p). At Medium settings, the progression is 135 FPS at 1080p, 109 FPS at 1440p (19.3% decrease), and 80 FPS at 4K (26.6% decrease). At High settings, the numbers are 101 FPS at 1080p, 82 FPS at 1440p (18.8% decrease), and 60 FPS at 4K (26.8% decrease). At Ultra settings, the pattern is 96 FPS at 1080p, 78 FPS at 1440p (18.8% decrease), and 57 FPS at 4K (26.9% decrease).

The consistent pattern of roughly 19% drops from 1080p to 1440p and roughly 26% drops from 1440p to 4K across all settings suggests that the scaling is primarily GPU-bound. If the CPU were the limiting factor, we would expect to see smaller percentage drops at higher resolutions, as the CPU's workload remains constant while the GPU's workload increases. The fact that the percentage drops are nearly identical across all four settings presets indicates that the RTX 5090 is the primary bottleneck at all tested configurations.

However, the absolute FPS values tell a more nuanced story. At 1080p Low, the 173 FPS average suggests the CPU is capable of feeding the GPU at very high rates, but the fact that this is not higher (given the GPU's benchmark scores) implies some CPU limitation. The gap between 1080p Low (173 FPS) and 4K Low (103 FPS) is 70 FPS, while the gap between 1080p Ultra (96 FPS) and 4K Ultra (57 FPS) is only 39 FPS. This narrowing gap at higher settings suggests that the GPU becomes more dominant as graphical load increases, and the CPU's influence diminishes.

Measured FPS Breakdown

At 1920x1080, the Low preset delivers an average of 173 FPS. The Medium preset averages 135 FPS with a minimum of 114 FPS and maximum of 155 FPS. The High preset averages 101 FPS, and the Ultra preset averages 96 FPS. The progression from Low to Medium represents a 38 FPS drop (22.0%), from Medium to High a 34 FPS drop (25.2%), and from High to Ultra a 5 FPS drop (5.0%). This shows that the largest performance cost occurs between Medium and High, while the jump from High to Ultra is relatively inexpensive.

At 2560x1440, the Low preset averages 139 FPS. The Medium preset averages 109 FPS with a minimum of 92 FPS and maximum of 125 FPS. The High preset averages 82 FPS, and the Ultra preset averages 78 FPS. The drop from Low to Medium is 30 FPS (21.6%), from Medium to High is 27 FPS (24.8%), and from High to Ultra is 4 FPS (4.9%). This mirrors the 1080p pattern, with the High-to-Ultra transition being the least costly.

At 3840x2160, the Low preset averages 103 FPS. The Medium preset averages 80 FPS with a minimum of 68 FPS and maximum of 92 FPS. The High preset averages 60 FPS, and the Ultra preset averages 57 FPS. The drop from Low to Medium is 23 FPS (22.3%), from Medium to High is 20 FPS (25.0%), and from High to Ultra is 3 FPS (5.0%). The consistency of these percentage drops across resolutions confirms that the settings presets scale predictably regardless of resolution, with the High-to-Ultra transition consistently costing only about 5% performance.

The minimum FPS data at Medium settings shows that the 1440p configuration maintains a minimum of 92 FPS, which is 84.4% of its average. At 4K, the minimum is 68 FPS, which is 85.0% of the 80 FPS average. At 1080p, the minimum is 114 FPS, which is 84.4% of the 135 FPS average. This consistency in the minimum-to-average ratio suggests stable frame pacing across resolutions at Medium settings, with the system maintaining at least 84% of its average performance even in demanding scenes.

GPU Role

The NVIDIA GeForce RTX 5090 is built on the Blackwell 2.0 architecture with a 5 nm process at TSMC, featuring 92,200 million transistors on a 750 mm² die. The GPU operates at a base clock of 2017 MHz with a boost clock of 2407 MHz, and its 32 GB of GDDR7 memory runs at 1750 MHz with 28 Gbps effective speed across a 512-bit bus, yielding 1.79 TB/s of memory bandwidth. The 21,760 shading units, 680 texture mapping units, and 176 raster output pipelines provide the raw compute power, while 170 ray tracing cores and 680 tensor cores handle specialized workloads.

In Microsoft Flight Simulator, the GPU's role is most evident at 4K resolutions where the RTX 5090's 32 GB VRAM and massive bandwidth come into play. The game's high-resolution textures and detailed terrain data benefit from the 1.79 TB/s bandwidth, which is among the highest available. The GPU's benchmark scores, including a 3DMark Steel Nomad DX12 score of 18,355 and PassMark G3D score of 39,650, place it in the 92nd percentile of all GPUs, yet the measured FPS at 4K Ultra (57 FPS) suggests that even this powerful GPU is challenged by the game's most demanding settings.

The GPU's nearest rivals in aggregate benchmarks include the NVIDIA Tesla P100 PCIe 16 GB at +0.3% delta, Tesla P100 PCIe 12 GB at +0.6%, and AMD Radeon RX 6850M XT at +1.1%, while the AMD Radeon Pro Vega 64X scores 1.4% higher. Despite these close benchmark scores, the RTX 5090's 32 GB VRAM is significantly larger than the Tesla P100's 16 GB or 12 GB, which may provide an advantage in memory-intensive scenarios. The Geekbench Vulkan score of 376,728 and OpenCL score of 334,370 indicate strong compute performance, though these are less directly relevant to gaming than the DirectX scores.

The GPU's FP32 performance of 104.8 TFLOPS and texture rate of 1,636.8 GTexel/s provide the computational headroom needed for complex flight simulator scenes with dense scenery, weather effects, and multiple aircraft. The 176 ROPs and 423.6 GPixel/s pixel rate ensure efficient rasterization at high resolutions. The data suggests that at 4K, the GPU is the primary determinant of performance, with the CPU providing sufficient support to avoid significant bottlenecking. The fact that 4K Ultra averages 57 FPS while 4K High averages 60 FPS indicates that the Ultra preset's additional graphical features (likely including higher shadow quality and more detailed textures) demand more from the GPU than the difference in visual quality might justify.
