Microsoft Flight Simulator

Microsoft Flight Simulator running on the Intel Core Ultra 9 275HX paired with the NVIDIA GeForce RTX 4080 Mobile delivers a genuinely capable experience across all three tested resolutions, but the data shows a clear pattern: this is a pairing that scales gracefully up to 4K while leaning hard on the CPU's single-thread muscle. The combo ranks 1205 out of 3714 tested configurations in this title, which places it in the top third of tested hardware for one of the most demanding flight simulators ever shipped. Measured results span 1080p through 2160p at Low, Medium, High, and Ultra presets, and every number below comes from actual measurement rather than estimation.

Resolution Scaling

The measured averages tell a straightforward story. At Low settings, framerates go 151 FPS at 1920x1080, 122 FPS at 2560x1440, and 90 FPS at 3840x2160. That is a 40% drop from 1080p to 4K — a substantial fall, but one that still leaves the game playable at the top resolution. At the Medium preset, the progression is 118, 95, and 70 FPS; at High it is 88, 71, and 53; and at Ultra it is 84, 68, and 50.

What does this scaling say about the limiting component? The key signal is the gap between the Ultra and Low results at each resolution. At 1080p, Ultra runs at 84 FPS against 151 FPS on Low — a 67 FPS spread, meaning the GPU is being pushed hard at maximum settings even at the lowest resolution. At 4K that spread narrows to 40 FPS (90 Low versus 50 Ultra), because the resolution itself becomes the dominant cost. Crucially, framerates do not flatten out at 1080p: Low settings at 1080p reach 151 FPS while Ultra sits at 84 FPS, which indicates the CPU is not the primary ceiling here. If the Core Ultra 9 275HX were the bottleneck, all four presets at 1080p would converge toward a single number. Instead, the settings-driven spread stays wide at every resolution, pointing to GPU-limited behavior throughout — the RTX 4080 Mobile with its 12 GB of GDDR6 and 432 GB/s of bandwidth is the component doing the heavy lifting, and the frame ceiling drops as the pixel count climbs. The scaling from 1080p to 1440p is also informative: the drop is moderate at every preset, which means 1440p is where this configuration hits its comfort zone.

FAQ

Q: Can this laptop combo run Microsoft Flight Simulator at 4K?

A: Yes. The measured average at 3840x2160 is 70 FPS on Medium, with a recorded range of 59 to 80 FPS. High drops the average to 53 FPS and Ultra to 50 FPS, so Medium is the practical 4K preset for this pairing.

Q: What is the highest measured framerate in the dataset?

A: 151 FPS, recorded at 1920x1080 on the Low preset. The lowest measured average is 50 FPS at 3840x2160 on Ultra.

Q: How does this combo rank against other tested configurations in this game?

A: It ranks 1205 out of 3714 tested combos, placing it in the upper portion of the results table for Microsoft Flight Simulator.

Q: Is the CPU fast enough for this simulation-heavy title?

A: The data suggests yes. The Core Ultra 9 275HX sits in the 94th percentile versus all CPUs, with a single-core Cinebench R23 score of 2204 and a Geekbench single-core score of 2458 — the kind of per-thread performance flight simulation depends on.

Q: Does the framerate stay stable at Medium settings?

A: The measured range gives a clear picture: 100 to 135 FPS at 1080p, 81 to 109 FPS at 1440p, and 59 to 80 FPS at 4K. The 4K result dips close to 60 FPS at the low end, so sensitivity to stutter exists there but the average remains smooth.

Q: How strong is the GPU in this pairing relative to the market?

A: The RTX 4080 Mobile sits in the 81st percentile versus all GPUs, with an average benchmark score of 38135. Its nearest rivals by aggregate score include the GeForce RTX 5080 Mobile (avgScore 38349) and the desktop GeForce RTX 4070 (avgScore 37648).

CPU Role

The Core Ultra 9 275HX is an Arrow Lake-HX mobile part with 24 cores and 24 threads, a 2.70 GHz base clock and a 5.40 GHz boost clock, built on TSMC's 3 nm process. It carries 3 MB of L2 cache per core and 36 MB of shared L3, with support for dual-channel DDR5 and 102.4 GB/s of memory bandwidth. The 55 W TDP and Intel BGA 2114 socket confirm this is a soldered mobile flagship, launched on January 12, 2025.

For Microsoft Flight Simulator, raw core count matters less than fast single threads — simulation titles typically run their main loop on a limited number of threads. Here the 275HX delivers a Cinebench R15 single-core score of 334, an R20 single-core score of 2809, an R23 single-core score of 2204, a Geekbench single-core score of 2458, and a PassMark single-thread score of 4713. Its multi-core credentials are equally strong: 35589 in Cinebench R23 multi-core, 20795 in Geekbench multi-core, and 55759 in PassMark multithreaded. Overall the CPU sits in the 94th percentile of all tested processors with an average benchmark score of 67469.

Against its nearest rivals, the 275HX essentially holds its ground: the Intel Xeon w5-3525 averages 67673 (a 0.3% edge over the 275HX), the AMD EPYC 4484PX averages 67822 (0.5% ahead), the AMD Ryzen Threadripper PRO 5955WX averages 67868 (0.6% ahead), and the Intel Xeon 6515P averages 67006 (0.7% behind). These are workstation chips, and the fact that a mobile processor trades blows within a single percentage point of them underlines how much CPU headroom this configuration has. That headroom shows up in the game data: the wide spread between Low and Ultra presets at 1080p — 151 versus 84 FPS — confirms the CPU is not clamping the framerate. The 5.40 GHz boost clock and strong per-core throughput keep the simulation side fed while the GPU determines where the ceiling lands.

Settings Recommendations

The measured rows make the recommendations easy to draw. At 1920x1080, High is the sweet spot: 88 FPS average with meaningful visual gains over Medium's 118 FPS, and even Ultra holds 84 FPS. If the display refresh rate exceeds the framerate targets, Medium at 1080p (118 FPS average, peaks of 135 FPS) is the pick for smoother motion.

At 2560x1440, Medium is the standout: 95 FPS average with a floor of 81 FPS. That floor matters — it means the framerate rarely leaves the smooth band even in worst moments. High at 1440p manages 71 FPS and Ultra drops to 68, both playable, but Medium's 81 FPS minimum is the strongest consistency result in the entire dataset.

At 3840x2160, the choice narrows. Ultra averages 50 FPS and High 53 — both borderline. Medium at 4K averages 70 FPS with a minimum of 59, which is the only 4K preset that keeps the worst moments near 60. The recommendation is therefore Medium at native 4K, or High at 1440p if a smoother average is preferred over pixel density. Low settings should be reserved for cases where framerate is the sole priority: they buy 151 FPS at 1080p and 122 FPS at 1440p, at a significant visual cost in a game built on scenery detail.

How This Combo Ranks

This pairing ranks 1205 out of 3714 tested combinations in Microsoft Flight Simulator — upper-third territory. Given that this title launched on August 17, 2020 and has remained a benchmark staple for punishing hardware, a mobile platform landing in the top third is a solid result.

Context matters for interpreting that rank. The GPU side sits in the 81st percentile versus all GPUs, while the CPU sits in the 94th percentile versus all CPUs. The rank in-game reflects the pairing: strong enough to clear most configurations, but behind the desktop flagship pairings that dominate the top of the table. Notably, the RTX 4080 Mobile's aggregate score of 38135 places it within a fraction of a percent of the GeForce RTX 5080 Mobile (38349, 0.6% ahead), ahead of the desktop RTX 4070 (37648, 1.3% behind the 4080 Mobile) and the Tesla P4 (37628, also 1.3% behind), with only the GeForce MX570 (38299, 0.4% ahead) also clustering nearby. On the compute side the card posts 159575 in Geekbench OpenCL, 145807 in Geekbench Vulkan, and 24926 in PassMark G3D — figures that support its standing against that rival cluster.

Measured FPS Breakdown

All figures below are measured averages; where min/max data was captured, it is noted.

3840x2160 (4K):

• Low: 90 FPS average
• Medium: 70 FPS average (min 59, max 80)
• High: 53 FPS average
• Ultra: 50 FPS average

2560x1440:

• Low: 122 FPS average
• Medium: 95 FPS average (min 81, max 109)
• High: 71 FPS average
• Ultra: 68 FPS average

1920x1080:

• Low: 151 FPS average
• Medium: 118 FPS average (min 100, max 135)
• High: 88 FPS average
• Ultra: 84 FPS average

The pattern across all twelve rows is consistent: each step up in preset costs roughly 15 to 30 FPS depending on resolution, and each step up in resolution costs roughly 20 to 30% of the framerate depending on preset. The Medium rows — the only ones with full min/max data — show frametime bands tight enough for smooth play at 1080p and 1440p, with 4K Medium remaining the one 4K configuration where the minimum stays close to 60 FPS. That is the number to remember when configuring this hardware: Medium at 4K, or anything at or below High at 1440p, is where the Core Ultra 9 275HX and RTX 4080 Mobile deliver a measured, stable Flight Simulator experience.
