Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding workloads in PC gaming, and the combination of the Intel Core Ultra 9 275HX with the NVIDIA GeForce RTX 4060 mobile GPU produces a dataset that reveals a clear performance hierarchy across resolutions and settings. The measured frames per second (FPS) show a system that is consistently capable of playable frame rates at 1080p, but which begins to strain under the immense graphical load of higher resolutions. The data indicates a configuration where the GPU becomes the primary bottleneck as resolution increases, while the CPU’s substantial core count and high boost clocks ensure that processing power is rarely the limiting factor. This analysis will break down the measured results, contextualize them against the component specifications, and explain what the numbers mean for a flight simulation enthusiast.

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

The measured FPS data shows a steep and consistent decline in performance as resolution scales from 1920x1080 to 3840x2160, a pattern that strongly indicates the GPU is the limiting component in this pairing. At Low settings, the average frame rate drops from 106 FPS at 1080p to 86 FPS at 1440p, and finally to 63 FPS at 4K. This represents a 40% reduction in frame rate from 1080p to 4K, a decline that is characteristic of a GPU that is being increasingly saturated by the pixel throughput demands of higher resolutions. The trend is even more pronounced at High settings, where the average FPS falls from 62 at 1080p, to 50 at 1440p, and then to 37 at 4K, a 40% drop from the 1080p figure. This scaling behavior suggests that the RTX 4060’s 8 GB of VRAM and 128-bit memory bus are being pushed to their limits, as the data shows a linear progression of performance loss that aligns with the increased pixel count, rather than a sudden cliff that might indicate a CPU limitation.

The data implies that the Intel Core Ultra 9 275HX is not the primary bottleneck in this scenario, as the FPS drop from 1080p to 1440p is roughly proportional to the increase in resolution, which is typical of a GPU-bound workload. If the CPU were the limiting factor, the FPS would remain relatively flat across resolutions, as the processor would be unable to feed the GPU with enough frames regardless of the graphical settings. The fact that the FPS drops significantly at each resolution step suggests that the RTX 4060 is working at near maximum capacity, and its performance ceiling is what determines the final frame rate. At 4K Ultra, the system only manages 35 FPS, which is a demanding scenario for any mobile GPU, but the data shows that the RTX 4060 is still able to render the scene, just at a frame rate that is below the 60 FPS target that many users would consider smooth.

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

The Intel Core Ultra 9 275HX is a 24-core, 24-thread processor based on the Arrow Lake architecture, with a base clock of 2.70 GHz and a boost clock of 5.40 GHz. This is a high-end mobile processor, and its benchmark scores reflect its capability: it achieves a Cinebench R23 multi-core score of 35589 and a single-core score of 2204, placing it in the 94th percentile of all CPUs tested. In the context of Microsoft Flight Simulator, which is known to be heavily dependent on single-thread performance for its core simulation logic, the processor’s high boost clock is a critical asset. The data shows that at 1080p Low settings, the system achieves 106 FPS, a figure that is likely limited by the GPU, but the CPU’s ability to maintain high frame rates at lower resolutions indicates that its single-thread performance is sufficient to keep up with the simulation’s demands.

The processor’s 24 cores and 36 MB of shared L3 cache provide ample headroom for background tasks and the game’s complex world-streaming systems, but the benchmark results suggest that the CPU is not the bottleneck in this configuration. Comparing the CPU to its nearest rivals, it is virtually tied with the Intel Xeon w5-3525, which scores 67673 in the average benchmark, a delta of -0.3% from the Core Ultra 9’s 67469 average. This means that in terms of raw processing power, the 275HX is performing exactly as expected for its class. In the game itself, the fact that the FPS drops are so consistent with resolution scaling points to the GPU being the limiting factor, meaning that the CPU is likely delivering frames faster than the RTX 4060 can render them, especially at lower resolutions where the GPU has less work to do.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4060 is a mobile GPU based on the Ada Lovelace architecture, featuring 8 GB of GDDR6 memory on a 128-bit bus, with a boost clock of 2460 MHz and a memory bandwidth of 272.0 GB/s. These specifications are modest for a 40-series card, and the benchmark results show that it performs in the 61st percentile of all GPUs, with an average benchmark score of 17639. Its nearest rivals include the AMD Radeon 780M, which is an integrated GPU, and the Radeon Pro 560, which is a much older professional card. This positioning suggests that the RTX 4060 is an entry-level dedicated GPU, and its performance in Microsoft Flight Simulator reflects this, as it struggles to maintain high frame rates at 4K Ultra, achieving only 35 FPS.

The 8 GB VRAM capacity is a significant factor in this game’s performance at high resolutions. Microsoft Flight Simulator is known for its massive textures and detailed scenery, which can quickly fill up VRAM. The data shows that at 4K High, the average FPS is 37, which is only 2 FPS higher than at 4K Ultra, suggesting that the game is hitting a memory or bandwidth wall rather than a pure compute limit. The 128-bit memory bus, which provides 272 GB/s of bandwidth, is also a limiting factor, as it may struggle to stream the necessary texture data at 4K resolutions. The GPU’s 3072 shading units and 15.11 TFLOPS of FP32 performance are adequate for 1080p gaming, but the data indicates that the card is out of its depth at 4K, where the pixel count and texture detail overwhelm its capabilities.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core Ultra 9 275HX and the NVIDIA GeForce RTX 4060 ranks 1804 out of 2996 tested combos in Microsoft Flight Simulator, placing it in the 40th percentile of all tested systems. This ranking is lower than what the CPU’s individual percentile (94th) might suggest, which reinforces the idea that the GPU is holding the system back. The CPU is a top-tier mobile processor, but when paired with a mid-range GPU, the overall system performance is dragged down to a level that is closer to the bottom half of all tested configurations. This is a classic case of a CPU-heavy pairing, where the processor has far more headroom than the GPU can utilize.

The rank of 1804 out of 2996 combos indicates that there are 1192 other tested configurations that perform worse than this pairing, but also that there are 1803 that perform better. This suggests that while the system is not a top performer, it is also not at the bottom of the barrel. The data implies that users who have this CPU and GPU combination should not expect to run the game at maximum settings at 4K, but they can achieve playable frame rates at 1080p with high settings. The ranking also highlights a potential upgrade path: if a user were to pair this CPU with a more powerful GPU, the system’s rank in this game would improve significantly, as the CPU is not the limiting factor in this scenario.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a complete picture of the system’s performance across all tested settings and resolutions. At 1920x1080, the system achieves an average of 106 FPS on Low settings, 83 FPS on Medium, 62 FPS on High, and 59 FPS on Ultra. The Medium settings also recorded a minimum FPS of 70 and a maximum of 95, indicating a relatively stable frame rate. Moving to 2560x1440, the average FPS drops to 86 on Low, 67 on Medium, 50 on High, and 48 on Ultra. The Medium settings at 1440p show a minimum of 57 and a maximum of 77 FPS, which is a wider variance than at 1080p, suggesting that the GPU is beginning to struggle with the increased pixel count.

At 3840x2160, the performance drops significantly. The system averages 63 FPS on Low, 49 FPS on Medium, 37 FPS on High, and 35 FPS on Ultra. The Medium settings at 4K show a minimum of 42 FPS and a maximum of 57 FPS, which is a substantial variance and indicates that the frame rate can dip below the 60 FPS target even on Medium settings. This data reveals that the system is only capable of maintaining a smooth 60+ FPS experience at 1080p on Low settings, and it drops below 60 FPS for all settings at 1440p and 4K. The Ultra preset at 1080p is the only way to get close to 60 FPS at a high visual quality, but it still falls just short at 59 FPS.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this system depend on the user’s priority for visual fidelity versus frame rate smoothness. For a consistent 60 FPS experience, the only viable option is 1920x1080 with Low settings, which yields 106 FPS, or Medium settings at 83 FPS, which still provides a comfortable margin above 60 FPS. At 1080p High settings, the average FPS is 62, which is technically above 60, but it is close enough that any slight variance could cause noticeable dips. The Ultra preset at 1080p, with an average of 59 FPS, is not recommended for smooth gameplay, as it is below the 60 FPS target.

For users who prefer higher resolutions, the data shows that 2560x1440 on Medium settings, with an average of 67 FPS, is the best balance, as it provides a higher pixel density while still maintaining an average frame rate above 60. However, the minimum FPS of 57 indicates that there will be occasional dips below 60, which might be noticeable in a flight simulator where smooth panning is important. At 4K, the system is not capable of delivering a smooth experience on any setting, with the best average being 63 FPS on Low, but this is likely to feel less stable than the 1440p Medium settings. The data suggests that for the best overall experience, users should prioritize 1080p High settings for a near-60 FPS experience with good visual quality, or 1440p Medium for a higher resolution with a slightly less stable frame rate.
