Microsoft Flight Simulator

Microsoft Flight Simulator running on the Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 4090 Mobile delivers a thoroughly playable experience at every resolution tested, with the benchmark data showing the GPU as the clear limiting factor at higher settings and the CPU comfortably capable of feeding it. The combo ranks 815 out of 3714 tested hardware pairings in this game — a solid upper-tier placement that reflects a well-balanced mobile pairing rather than a desktop-class powerhouse. All figures below are drawn directly from measured benchmark rows.

FAQ

Q: What frame rate does this combo achieve at 4K in Microsoft Flight Simulator?

A: At 3840x2160, measured averages are 98 fps on Low, 77 fps on Medium, 58 fps on High, and 55 fps on Ultra. The Medium row also includes a minimum of 65 fps and a maximum of 88 fps, making Medium the highest setting tier with full frame-time data recorded.

Q: Is 1080p CPU-limited with the Core Ultra 5 135H?

A: The data suggests only mild CPU pressure at 1080p. Averaging 166 fps on Low at 1920x1080 indicates the Ultra 5 135H keeps up with the RTX 4090 Mobile at the fastest measured setting, though the small gap between High (97 fps) and Ultra (92 fps) at the same resolution hints at approaching a ceiling.

Q: How does this hardware pairing rank among tested combinations in this game?

A: It ranks 815 out of 3714 combinations, placing it in the upper portion of tested pairings for Microsoft Flight Simulator.

Q: How does the CPU compare to its nearest rivals?

A: The Core Ultra 5 135H's average benchmark score of 29093 sits within a fraction of a percent of the AMD Ryzen 7 5800X (29123, a 0.1 percent gap), the Intel Xeon Phi 7210 (29245, 0.5 percent), the AMD Ryzen 5 5600XT (28940, 0.5 percent), and the Intel Core i5-13500HX (29270, 0.6 percent). It is effectively performance-locked with all four.

Q: How does the RTX 4090 Mobile compare to its nearest rivals?

Q: Does VRAM capacity matter for this game at 4K?

A: The GPU carries 16 GB of GDDR6 on a 256-bit bus with 576.0 GB/s of bandwidth — capacity and bandwidth that comfortably handle the 4K Ultra row measured at 55 fps average without any data indicating a memory bottleneck.

GPU Role

The NVIDIA GeForce RTX 4090 Mobile is the centerpiece of this pairing. Built on TSMC's 5 nm process with the AD103 chip, it packs 45,900 million transistors onto a 379 mm² die at a density of 121.1 million transistors per square millimeter. The shader count stands at 9728 units, backed by 304 texture mapping units, 112 render output units, 76 RT cores, and 304 tensor cores. Raw throughput figures include 32.98 TFLOPS of FP32 compute (with FP16 at a 1:1 ratio of the same 32.98 TFLOPS), a pixel fill rate of 189.8 GPixel/s, and a texture fill rate of 515.3 GTexel/s.

Clocks run from a 1335 MHz base to a 1695 MHz boost, with 18 Gbps effective memory speed on 16 GB of GDDR6 across the 256-bit bus. That 576.0 GB/s of bandwidth matters for a simulator like Microsoft Flight Simulator, which streams large scenery and terrain datasets — the measured 4K Medium row holding a 65 fps minimum suggests bandwidth is not collapsing under texture and asset streaming pressure.

The frame rate scaling pattern across resolutions points to a GPU-bound profile at higher settings. Dropping from 1080p Ultra (92 fps) to 4K Ultra (55 fps) costs roughly 40 percent of the frame rate, a decline consistent with a shader- and fill-rate-limited workload rather than a CPU bottleneck — if the processor were the limiter, frame rates would flatten across resolutions instead of scaling downward.

Against the broader GPU field, the RTX 4090 Mobile sits in the 84th percentile of all GPUs, and its average benchmark score of 43667 places it within one percent of everything from the Quadro M6000 to the RTX A6000. In practical terms: a very strong mobile GPU, but not a class of its own. Its PassMark G3D score of 27212 and GPU compute score of 12347, alongside a Geekbench OpenCL result of 180831 and Vulkan result of 170774, reinforce that picture of high-end-but-not-flagship compute muscle. The card supports DirectX 12 Ultimate (12_2), Vulkan 1.4, and OpenGL 4.6, all of which cover Microsoft Flight Simulator's DirectX 12 feature requirements.

Settings Recommendations

The measured rows make the trade-offs explicit.

For 4K play, Medium is the sweet spot. It averages 77 fps with a 65 fps minimum and an 88 fps maximum — the only 4K row with min/max data, and the only 4K configuration that holds above 60 fps in its worst recorded moments. Stepping up to High drops the average to 58 fps, below the 60 fps line, and Ultra falls further to 55 fps. Low, at 98 fps average, buys a lot of speed but forgoes the visual fidelity that makes flight simulation worthwhile. Medium at 4K is the verdict.

At 2560x1440, Medium again posts the most complete dataset — 104 fps average, 88 fps minimum, 119 fps maximum — while High manages 78 fps and Ultra 74 fps. Any tier is playable here; even Ultra stays above 60. Players wanting the richest visuals without dipping into slideshow territory can run Ultra at 1440p with confidence, and Low's 133 fps average makes it the pick for high-refresh 1440p panels.

At 1920x1080, the entire preset range is viable: 166 fps on Low, 129 on Medium (with a 109 minimum and 148 maximum), 97 on High, and 92 on Ultra. Ultra at 1080p is the best-looking configuration that still clears 90 fps. The narrow five-frame spread between High and Ultra, however, indicates diminishing visual-per-frame returns at the top end.

A general pattern emerges from the data: Medium is the best-documented and best-balanced preset at every resolution, combining high averages with recorded minimums that confirm frame-rate stability.

Measured FPS Breakdown

All rows below are measured averages from the benchmark dataset.

3840x2160 (4K):

• Low: 98 fps average
• Medium: 77 fps average (65 min / 88 max)
• High: 58 fps average
• Ultra: 55 fps average

2560x1440:

• Low: 133 fps average
• Medium: 104 fps average (88 min / 119 max)
• High: 78 fps average
• Ultra: 74 fps average

1920x1080:

• Low: 166 fps average
• Medium: 129 fps average (109 min / 148 max)
• High: 97 fps average
• Ultra: 92 fps average

The scaling story is clean and consistent. Between 1080p and 4K at identical settings, frame rates fall by roughly 45 percent on Low (166 to 98), 40 percent on Medium (129 to 77), 40 percent on High (97 to 58), and 40 percent on Ultra (92 to 55). Settings exert a second, gentler pressure: at 4K, moving from Low to Ultra costs 43 fps, or about 44 percent. The Medium min/max spreads — 23 fps at 4K, 31 fps at 1440p, 39 fps at 1080p — show frame-time variance shrinking in relative terms as resolution climbs, which is typical of a GPU becoming more consistently saturated.

Notably, the difference between High and Ultra is small at every resolution: four fps at 4K, four fps at 1440p, and five fps at 1080p. The data indicates Ultra costs relatively little performance over High on this hardware, while the Medium-to-High step (19 fps at 4K, 26 fps at 1440p, 32 fps at 1080p) is where the bulk of the performance cost lives.

How This Combo Ranks

Within Microsoft Flight Simulator specifically, the Core Ultra 5 135H plus RTX 4090 Mobile pairing ranks 815 out of 3714 tested combinations. That placement puts it ahead of the large majority of tested pairings in this title — a top-tier result for a mobile platform, where thermal and power constraints typically hold configurations below desktop equivalents.

The rank is consistent with the component-level percentiles. The CPU sits in the 81st percentile of all processors; the GPU sits in the 84th percentile of all GPUs. Neither component is an extreme outlier, but both are firmly upper-tier, and their balance is what makes the combo effective: the measured frame-rate scaling shows neither part badly starving the other.

Context from rival data supports the placement. The CPU's average score of 29093 is statistically tied with desktop and mobile rivals spanning the Ryzen 7 5800X, Ryzen 5 5600XT, Xeon Phi 7210, and Core i5-13500HX — all within 0.6 percent. The GPU's 43667 average is similarly bracketed by Quadro M6000 variants, the RTX 5050 Mobile, and the RTX A6000. In a simulator this CPU-heavy, having a processor that holds its own against those rivals while paired with an 84th-percentile GPU is what boosts the combo to its 815th-place standing.

CPU Role

Microsoft Flight Simulator is a simulation title with heavy main-thread demands, and the Core Ultra 5 135H meets them adequately rather than spectacularly. The chip is a 14-core, 18-thread Meteor Lake design on Intel's 7 nm process, with a 3.60 GHz base clock and a 4.60 GHz boost. Cache allocation includes 112 KB of L1 per core, 2 MB of L2 per core, and a shared 18 MB of L3. Memory support covers DDR5 on a dual-channel bus delivering 89.6 GB/s of bandwidth, and the chip integrates Arc Xe-LPG 96EU graphics — unused here in a discrete-pairing scenario. It fits the Intel BGA 2049 socket and carries a launch MSRP of $342.

Single-thread results matter most for this game, and they are respectable: 244 in Cinebench R15 single-core, 1105 in R20, 1700 in R23, and 3521 in PassMark single-thread. That single-thread figure is what keeps frame pacing steady in a simulator known for main-thread bottlenecks. Multi-thread results — 1718 in R15, 7834 in R20, 11875.5 in R23, and 22422 in PassMark multithread — show solid throughput for a mobile part, along with a PassMark physics score of 1482.

The evidence that the CPU is not the primary limiter comes from the measured data itself. Frame rates scale steeply with resolution and settings at every tier — behavior that would not appear if the processor were capping performance. The 1080p Low average of 166 fps represents the CPU's effective ceiling in this configuration, and since the 4K Low row reaches 98 fps, the processor retains substantial headroom at higher resolutions. Where the CPU's limits begin to show is the top of the chart: 92 fps at 1080p Ultra on a GPU in the 84th percentile suggests some shared constraint at maximum settings, though the data cannot fully separate the two contributors.

Against its rival set, the Ultra 5 135H trades blows within a percentage point on aggregate scores, and its 81st-percentile standing against all CPUs confirms it as an upper-tier mobile processor. For a flight simulator, that translates to a simple verdict: sufficient single-thread speed and core count to let the RTX 4090 Mobile do its job, with the measured 77 fps 4K Medium average (65 minimum) standing as the practical proof.
