Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding workloads in PC gaming, and the combination of the Intel Core Ultra 7 165H and NVIDIA GeForce RTX 5090 Mobile delivers a performance profile that is as impressive as it is revealing. The data shows a system capable of excellent frame rates at high resolutions, yet the performance scaling across settings suggests that the CPU, not the GPU, is the primary constraint in several scenarios. With a combo rank of 784 out of 3714 tested configurations, this pairing sits comfortably in the top quartile, but the benchmark results indicate that users must be strategic about settings to get the best experience.

FAQ

Q: What is the best resolution to play Microsoft Flight Simulator with this hardware?

A: The data indicates that 2560x1440 is the sweet spot. At Medium settings, the system achieves an average of 109 FPS, which is 36% higher than the 80 FPS at 4K Medium. At High settings, it delivers 82 FPS at 1440p compared to 60 FPS at 4K, offering a substantial performance buffer without sacrificing the High preset.

Q: Should I use the Ultra preset for the best visual quality?

A: While Ultra is available, the measured performance shows a significant cost. At 4K Ultra, the average FPS drops to 57, which is below the 60 FPS threshold that many consider ideal for smooth flight simulation. At 1440p Ultra, the system hits 78 FPS, which is playable, but the step down to High settings at 1440p yields 82 FPS, a marginal 5% difference in frame rate that may not justify the visual upgrade for all users.

Q: How does the CPU affect performance in this game?

A: The Intel Core Ultra 7 165H has 16 cores and 22 threads. The benchmark data suggests it is a limiting factor at lower resolutions. For instance, at 1080p Low, the system hits 173 FPS, but at 4K Low it drops to 103 FPS. This scaling pattern indicates that the CPU is not able to feed the GPU fast enough at higher frame rates, which is a common bottleneck in simulation titles.

Q: Is the RTX 5090 Mobile overkill for this game?

A: The data suggests that the GPU has significant headroom. The RTX 5090 Mobile has 24 GB of GDDR7 memory, but the measured FPS indicates that at 4K Ultra, the system only manages 57 FPS. This suggests the CPU is holding back the GPU, as the GPU is likely capable of higher frame rates if the processor could keep up with the simulation's physics and AI calculations.

Q: Does the game benefit from the RTX 5090 Mobile's 24 GB of VRAM?

A: At the tested settings and resolutions, the data does not show a scenario where VRAM capacity is a limiting factor. The performance differences between settings are more attributable to GPU compute load and CPU bottlenecks. However, the 24 GB frame buffer provides future-proofing for high-resolution textures and add-ons, though this is not directly reflected in the measured FPS numbers.

Q: What is the worst performance scenario in the data?

A: The most demanding scenario is 4K Ultra, which yields an average of 57 FPS. This is the lowest average in the entire dataset. Interestingly, the 4K High preset produces 60 FPS, so the step from High to Ultra at 4K only costs 3 FPS, suggesting that the Ultra preset may not be the primary performance driver at this resolution.

Settings Recommendations

The measured data provides a clear hierarchy of performance across presets and resolutions. For the best experience, prioritizing frame rate stability is key for a flight simulator, where smooth camera panning and detailed terrain rendering are critical. The data shows that the Medium preset offers the best balance of performance and visual fidelity, especially when considering the minimum frame rates provided.

At 4K, the Medium preset delivers an average of 80 FPS with a minimum of 68 FPS and a maximum of 92 FPS. This is a playable range, but the 68 FPS minimum indicates occasional dips. The High preset at 4K averages 60 FPS, which is exactly at the threshold of smoothness but provides no headroom for complex scenes. The Ultra preset at 57 FPS is the only option that falls below the 60 FPS mark, making it the least desirable for a consistent experience.

At 1440p, the Medium preset shines with an average of 109 FPS and a minimum of 92 FPS. This is a significant improvement over 4K and provides a very smooth experience. The High preset at 82 FPS is also excellent and offers better visual fidelity. The Ultra preset at 78 FPS is viable, but the 5% gain in frame rate from moving to High is minimal. For the best overall experience, the 1440p High preset is recommended, as it provides a high average frame rate and visual quality without pushing the system to its limits.

At 1080p, the Medium preset achieves 135 FPS with a minimum of 114 FPS, which is excellent. The High preset at 101 FPS is also very strong. The Low preset at 173 FPS is unnecessary for a smooth experience. The recommended setting is the 1440p High preset, as it delivers 82 FPS and represents the best combination of visual fidelity and performance headroom. For users who prioritize maximum smoothness, the 1440p Medium preset at 109 FPS is the best choice.

GPU Role

The NVIDIA GeForce RTX 5090 Mobile is a formidable piece of hardware, featuring 10496 shading units and 82 RT cores on the Blackwell 2.0 architecture. Its 24 GB of GDDR7 memory on a 256-bit bus provides a bandwidth of 896.0 GB/s, which is substantial for high-resolution textures. The GPU's base clock is 990 MHz with a boost clock of 1515 MHz, and it has a TDP of 95 W.

The data shows that the GPU is not the primary bottleneck in this system. At 4K Low, the system achieves 103 FPS, while at 1440p Low, it hits 139 FPS, and at 1080p Low, it reaches 173 FPS. This scaling is linear with the pixel count, suggesting that the GPU is handling the load efficiently. However, the performance difference between Low and Ultra at the same resolution is telling. At 4K, the drop from Low to Ultra is 46 FPS (103 to 57), which is a 45% reduction in performance. This indicates that the Ultra preset is heavily taxing the GPU's compute capabilities, even with its high shader count.

The GPU's performance in this game is further contextualized by its benchmark scores. It scores 30034 in Passmark G3D and 5871 in 3DMark Steel Nomad, placing it in the 84th percentile of all GPUs. The data suggests that the RTX 5090 Mobile is capable of more than what the CPU allows in this specific title. The fact that the system cannot maintain 60 FPS at 4K Ultra, despite the GPU's raw power, points to the CPU being the limiting factor in this pairing.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system's performance across three resolutions and four settings presets. The table below summarizes the average frame rates, with minimum and maximum values where available.

At 1920x1080, the system delivers high frame rates across all settings. The Low preset achieves an average of 173 FPS. The Medium preset averages 135 FPS, with a minimum of 114 FPS and a maximum of 155 FPS. The High preset averages 101 FPS. The Ultra preset averages 96 FPS. This resolution shows the system is capable of very high refresh rate gaming, but the gap between Medium and High is 34 FPS, indicating that the High preset is more demanding.

At 2560x1440, the performance remains strong. The Low preset averages 139 FPS. The Medium preset averages 109 FPS, with a minimum of 92 FPS and a maximum of 125 FPS. The High preset averages 82 FPS. The Ultra preset averages 78 FPS. The step from Medium to High is a 27 FPS drop, which is significant. The step from High to Ultra is only 4 FPS, suggesting diminishing returns at this resolution.

At 3840x2160, the system starts to show its limits. The Low preset averages 103 FPS. The Medium preset averages 80 FPS, with a minimum of 68 FPS and a maximum of 92 FPS. The High preset averages 60 FPS. The Ultra preset averages 57 FPS. The data shows that at 4K, the Medium preset is the only one that provides a comfortable margin above 60 FPS, while the High and Ultra presets are right at or below that threshold.

How This Combo Ranks

The combination of the Intel Core Ultra 7 165H and NVIDIA GeForce RTX 5090 Mobile ranks 784 out of 3714 tested combos for Microsoft Flight Simulator. This places the system in the top 21% of all tested configurations, which is a strong result given the demanding nature of the game. The rank indicates that while this is not the absolute top-tier setup, it outperforms the vast majority of systems in this specific title.

The ranking is particularly noteworthy because it is a mobile platform. The RTX 5090 Mobile, despite its "Mobile" designation, is a high-performance part with a 95 W TDP and 24 GB of VRAM. The Core Ultra 7 165H is a 28 W processor, which is a power-efficient chip that may not be the fastest for gaming. The fact that this combo ranks in the top quartile suggests that the GPU is doing most of the heavy lifting, but the CPU is not holding the system back as much as one might expect.

The data also shows that the combo's rank is relative to other systems. With 3714 total combos, a rank of 784 means there are 2930 combos that perform worse in this game. This is a solid position, but it also highlights that there are more powerful combinations available, likely with more robust desktop CPUs. The measured FPS data supports this, as the system struggles to maintain 60 FPS at 4K Ultra, which would be a more achievable target for a high-end desktop CPU paired with a comparable GPU.

CPU Role

The Intel Core Ultra 7 165H is a mobile processor with 16 cores and 22 threads, based on the Meteor Lake architecture on a 7 nm process. It has a base clock of 3.80 GHz and a boost clock of 5.00 GHz. The CPU features 24 MB of shared L3 cache and supports dual-channel DDR5 memory with a bandwidth of 89.6 GB/s. Its TDP is 28 W, which is typical for a mobile part.

In Microsoft Flight Simulator, the CPU is responsible for simulating the world, including physics, AI traffic, and weather systems. The data shows that the CPU is a significant factor in performance. The most telling evidence is the FPS scaling with resolution. At Low settings, the system achieves 173 FPS at 1080p, 139 FPS at 1440p, and 103 FPS at 4K. If the GPU were the only factor, we would expect the FPS to scale inversely with the pixel count. However, the FPS at 1080p is only 25% higher than at 1440p, and 40% higher than at 4K. This non-linear scaling suggests that the CPU is hitting a limit at higher frame rates.

The CPU's benchmark scores provide additional context. It scores 14551 in Cinebench R23 multicore and 1759 in singlecore. Its Passmark multithread score is 25933. These scores indicate a capable processor, but not one that is top-tier for gaming. The CPU's nearest rivals in terms of average benchmark score are the Intel Core Ultra 5 338H and AMD EPYC 4244P, with a delta of 0.3% and -0.4% respectively. This suggests the CPU is comparable to mid-range desktop chips from a few years ago.

The data points to the CPU being the primary bottleneck at 1080p and 1440p with lower settings. At 1080p Low, the system is likely CPU-bound, as the GPU is not being fully utilized. This is a common issue in flight simulators, where the simulation logic is complex and does not scale well with GPU performance. The result is that the RTX 5090 Mobile's potential is not fully realized in this configuration, as the CPU cannot provide it with enough frames to render.
