Microsoft Flight Simulator

Microsoft Flight Simulator remains one of the most demanding titles in the benchmark suite, and the combination of the Intel Core Ultra 7 165H and NVIDIA GeForce RTX 5090 produces a distinctive performance profile. The data reveals a system that is heavily influenced by resolution, with the CPU becoming an increasingly significant factor as pixel count decreases. This analysis breaks down the measured frames per second (FPS) across three resolutions and four quality presets, interpreting the results within the context of the hardware's specifications and its standing among 2,996 tested combinations.

Resolution Scaling

The measured FPS data shows a clear and consistent pattern of performance degradation as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average frame rate drops from 101 FPS at 1080p to 82 FPS at 1440p, and finally to 60 FPS at 4K. This represents a 19% reduction from 1080p to 1440p, and a further 27% reduction from 1440p to 4K. The scaling is nearly linear, suggesting that the rendering workload is scaling predictably with the pixel count.

Examining the Low preset reveals a more dramatic drop. At 1080p, the system achieves 173 FPS, which falls to 139 FPS at 1440p (a 20% decrease) and then to 103 FPS at 4K (a 26% decrease from 1440p). The absolute delta between 1080p and 4K at Low settings is 70 FPS, compared to a 41 FPS delta at High settings. This larger absolute drop at lower settings indicates that the GPU is not the sole limiting factor at 1080p Low; the CPU is beginning to cap performance, preventing the frame rate from scaling fully with the reduced graphical load.

The Medium preset provides the most complete data, including minimum and maximum FPS values. At 1080p Medium, the average is 135 FPS with a range of 114 to 155 FPS. At 1440p Medium, the average drops to 109 FPS (range of 92 to 125 FPS), and at 4K Medium, the average is 80 FPS (range of 68 to 92 FPS). The frame time consistency, as indicated by the gap between min and max, remains relatively stable across resolutions, which suggests that the game's simulation thread is not causing severe hitches even when the GPU load increases.

The scaling behavior points to a system where the RTX 5090 is the primary driver of performance at 4K, but the Core Ultra 7 165H becomes a more prominent bottleneck at 1080p. At 4K Ultra, the average FPS is 57, which is only 3 FPS lower than the 4K High result of 60 FPS. This small delta between High and Ultra at 4K suggests that the GPU is heavily saturated, and the additional graphical fidelity of the Ultra preset has a minimal impact on the frame rate because the rendering pipeline is already near its limit. Conversely, at 1080p, the difference between High (101 FPS) and Ultra (96 FPS) is also small, but the absolute headroom above 100 FPS indicates that neither component is fully maxed out, leaving performance in a more balanced territory.

GPU Role

The NVIDIA GeForce RTX 5090 is a flagship mobile GPU built on the Blackwell 2.0 architecture with a 5 nm process node. It features 32 GB of GDDR7 memory on a 512-bit bus, providing a bandwidth of 1.79 TB/s. The GPU's boost clock is rated at 2407 MHz, and it contains 21,760 shading units. These specifications are directly reflected in the benchmark results, where the GPU achieves an average score of 79,842 and sits in the 92nd percentile of all GPUs.

The data shows that the RTX 5090's immense memory bandwidth and capacity are not fully utilized by Microsoft Flight Simulator at lower resolutions, but they become crucial at 4K. The transition from 1080p to 4K at High settings reduces the average FPS from 101 to 60, a 41% drop. This is a substantial reduction that highlights the GPU's role in pixel pushing. The 32 GB VRAM buffer is more than sufficient for the highest-resolution textures, but the raw compute throughput is what dictates the frame rate at 4K, where the GPU is clearly the limiting component.

The GPU's benchmark percentile of 92 places it well ahead of most competitors, but its nearest rivals in the database are not desktop gaming cards. The nearestRivals list includes the NVIDIA Tesla P100 PCIe 16 GB (deltaPct 0.3), the Tesla P100 PCIe 12 GB (deltaPct 0.6), and the AMD Radeon RX 6850M XT (deltaPct 1.1). These results indicate that the RTX 5090's raw computational power is comparable to professional-grade compute accelerators, yet in this game, the performance is still capped by the CPU at lower resolutions. The GPU's passmark G3D score of 39,650 and its DirectX 12 score of 185 confirm its high-end standing, but the in-game data reveals that the RTX 5090 only reaches its full potential when the resolution is high enough to keep it busy.

CPU Role

The Intel Core Ultra 7 165H is a 16-core, 22-thread processor based on the Meteor Lake architecture. It has a base clock of 3.80 GHz and a boost clock of 5.00 GHz, with 24 MB of shared L3 cache. The processor's TDP is rated at 28 watts, which is a mobile-focused power envelope. In the CPU benchmark suite, it scores 14,551 in Cinebench R23 multi-core and 1,759 in single-core, placing it in the 84th percentile of all CPUs.

The CPU's impact on Microsoft Flight Simulator becomes most apparent when examining the 1080p results. The difference between the Low preset (173 FPS) and the High preset (101 FPS) is 72 FPS, which is a massive gap that cannot be explained by GPU load alone. At 1080p Low, the GPU is rendering relatively simple scenes, and the frame rate is likely being limited by the CPU's single-thread performance and the game's simulation logic. The boost clock of 5.00 GHz is helpful here, but the 28 W TDP suggests that sustained turbo frequencies may be limited under heavy load.

Comparing the CPU to its nearest rivals provides context for its performance. The Intel Core Ultra 5 338H has an average score of 33,989, which is only 0.3% lower than the Core Ultra 7 165H's average of 34,083. This indicates that the Ultra 7's additional cores do not translate into a significant advantage in the aggregate benchmark. The AMD Ryzen 7 3700X, a desktop processor, scores slightly higher at 34,260 (deltaPct -0.5), showing that the mobile Ultra 7 is competitive with older desktop parts. However, in this game, the CPU's 16 cores and 22 threads are less important than its single-core speed, and the data suggests that the processor is holding back the RTX 5090 at 1080p, where the GPU is idle waiting for the CPU to feed it frames.

FAQ

Q: Why does the FPS drop so much from 1080p to 4K at Low settings?

A: At 1080p Low, the average FPS is 173, which drops to 103 at 4K Low. This 70 FPS reduction is because the RTX 5090 is not the limiting factor at 1080p; the Core Ultra 7 165H caps the frame rate. As resolution increases, the GPU becomes the bottleneck, and its workload scales with pixel count, leading to a larger absolute drop.

Q: Is the Core Ultra 7 165H a bottleneck for the RTX 5090 in this game?

A: The data indicates yes at lower resolutions. At 1080p High, the average FPS is 101, while at 4K High it is 60. The fact that the 1080p result is not significantly higher suggests that the CPU's single-thread performance (boost clock of 5.00 GHz) is limiting the frame rate, as the GPU has ample headroom to render more frames if the CPU could supply them.

Q: What is the best resolution for this combo based on the data?

A: The 2560x1440 resolution appears to be the sweet spot. At High settings, it achieves 82 FPS, which is a good balance between visual fidelity and smoothness. The 4K results are playable (60 FPS at High), but the 1440p results offer higher frame rates without a massive drop in image quality.

Q: How does the RTX 5090 compare to its nearest rivals in the database?

A: The RTX 5090 has an average benchmark score of 79,842, which is 0.3% higher than the NVIDIA Tesla P100 PCIe 16 GB and 1.1% higher than the AMD Radeon RX 6850M XT. This places it in the 92nd percentile of all GPUs, indicating it is a top-tier performer, though its in-game performance is moderated by the CPU.

Q: Are the minimum FPS values consistent across resolutions?

A: For the Medium preset, the minimum FPS at 1080p is 114, at 1440p it is 92, and at 4K it is 68. The frame time consistency is maintained, showing that the game does not experience severe stutters as resolution increases, but the overall frame rate decreases steadily.

Q: Does the Ultra preset provide a significant improvement over High?

A: The data shows minimal gains. At 4K, High averages 60 FPS and Ultra averages 57 FPS, a difference of only 3 FPS. At 1080p, High averages 101 FPS and Ultra averages 96 FPS, a 5 FPS difference. This suggests that the Ultra preset's additional graphical features have a negligible impact on performance for this hardware.

How This Combo Ranks

The combination of the Intel Core Ultra 7 165H and NVIDIA GeForce RTX 5090 is ranked 586th out of 2,996 tested combinations in Microsoft Flight Simulator. This places the combo in the top 20% of all systems tested, which is a strong showing given the game's demanding nature. The rank of 586 reflects the fact that while the GPU is exceptionally powerful, the CPU's mobile-oriented design (28 W TDP) prevents it from achieving a higher standing.

The ranking is a composite of the CPU's 84th percentile and the GPU's 92nd percentile performance. The gap between these two percentiles suggests that the system is not perfectly balanced for this particular title. Systems with higher-ranking CPUs paired with the same GPU would likely score higher, as the CPU bottleneck at lower resolutions would be alleviated. Conversely, the GPU's high percentile ensures that at 4K, the system performs admirably, which is where many high-end flight sim enthusiasts would operate.

Given that the combo ranks 586th, it outperforms the vast majority of systems in the database. However, the delta between the CPU and GPU percentiles indicates that this is a GPU-heavy system. The data suggests that the RTX 5090 is the primary driver of the combo's rank, while the Core Ultra 7 165H contributes to a lesser extent. For users prioritizing maximum frame rates at 1080p, this combo may underperform relative to a desktop CPU with a higher clock speed, but for 4K gaming, the rank is likely to be competitive.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the user's resolution and frame rate preference. At 3840x2160, the High preset delivers an average of 60 FPS, which is the standard for smooth gameplay. The Ultra preset drops to 57 FPS, which is only a 5% reduction, but the visual gains are likely minimal. The Medium preset at 4K yields 80 FPS, which is a significant improvement over High and is the best option for users who want to stay well above 60 FPS.

At 2560x1440, the High preset provides 82 FPS, which is a good balance. The Medium preset offers 109 FPS, which is ideal for high-refresh-rate monitors (though the game's simulation nature means lower refresh rates are acceptable). The Ultra preset at 78 FPS is also viable, but the drop from High is only 4 FPS, making High the more efficient choice. For 1920x1080, the High preset at 101 FPS is recommended, as it provides a smooth experience without the excessive CPU load that comes with the Low preset (173 FPS), which does not offer a proportional visual benefit.

The Medium preset consistently shows the best balance of performance and quality across all resolutions. At 1080p Medium, the average is 135 FPS with a minimum of 114 FPS, ensuring no frame drops below the 60 FPS threshold. At 1440p Medium, the average is 109 FPS, and at 4K Medium, it is 80 FPS. The Medium preset is the safest recommendation for a consistently smooth experience across all resolutions, as it provides the highest frame rates while maintaining a reasonable visual fidelity. The data shows that the jump from Low to Medium is large (135 vs 173 FPS at 1080p), but the visual improvement is substantial, making Medium the preferred starting point.
