Microsoft Flight Simulator

# Microsoft Flight Simulator — Intel Core Ultra 5 235HX + NVIDIA GeForce RTX 4060 Mobile

This combination delivers playable but not exceptional performance in Microsoft Flight Simulator, with the data showing a clear pattern: the system scales from a smooth 1080p experience at high settings to a barely playable 4K at ultra. The measured frame rates reveal a GPU-bound configuration at higher resolutions, while the CPU's strong single-core performance keeps 1080p results respectable. The combo ranks in the 61st percentile (2268 out of 3714 tested combinations), placing it firmly in the mid-pack for this demanding flight simulator.

Resolution Scaling

The measured FPS data shows a steep and consistent drop as resolution increases, which is the classic signature of GPU-bound performance. At 1080p Low, the system produces 106 FPS average; at 1440p Low, that falls to 86 FPS (a 19% reduction); at 4K Low, it drops to 63 FPS (another 27% reduction). This scaling pattern indicates that the RTX 4060 Mobile is the primary limiting component once pixel count rises, as the CPU has enough headroom to feed the GPU at lower resolutions but cannot compensate for the sheer pixel workload at 4K.

The gap between settings widens dramatically at higher resolutions, which further confirms GPU limitation. At 1080p, the spread from Low (106 FPS) to Ultra (59 FPS) is 47 FPS — a significant but manageable range. At 1440p, that spread narrows to 38 FPS (86 Low vs. 48 Ultra), and at 4K it narrows further to 28 FPS (63 Low vs. 35 Ultra). When the GPU is overwhelmed at 4K, even dropping to Low settings cannot restore high frame rates; the 63 FPS at 4K Low is barely above the 59 FPS at 1080p Ultra. This compression of the settings range at higher resolutions is a textbook indicator that the GPU's rendering throughput is the bottleneck.

The 4K Ultra result of 35 FPS average is below the threshold most users consider smooth for a flight simulator, where precision control inputs benefit from higher frame rates. The 4K High result of 37 FPS is only marginally better, suggesting that the GPU has hit a hard performance ceiling regardless of modest settings changes. At 1440p, the situation improves meaningfully: High settings deliver 50 FPS, Medium 67 FPS, and Low 86 FPS — all playable, with Medium being the sweet spot for a balance of visual quality and responsiveness.

At 1080p, the system shows its best behavior. Ultra settings produce 59 FPS, which is just at the edge of smoothness for this genre, while High delivers 62 FPS and Medium reaches 83 FPS. The Low setting at 106 FPS demonstrates that when the GPU is not heavily taxed, the CPU can push frame rates well beyond the 60 FPS threshold. The 1080p Medium result (83 FPS) with a minimum of 70 FPS and maximum of 95 FPS shows consistent frame pacing, which is critical for a simulator where sudden stutters can disrupt the experience.

CPU Role

The Intel Core Ultra 5 235HX brings 14 cores and 14 threads, with a base clock of 2.90 GHz and a boost clock of 5.10 GHz. This is a hybrid configuration without Hyper-Threading, which means the 14 threads match the core count exactly. The processor's single-core performance is particularly relevant for Microsoft Flight Simulator, a title known for its heavy reliance on single-threaded rendering tasks. The Cinebench R23 single-core score of 4903 places this CPU in the 91st percentile of all processors, indicating strong per-core capabilities that should translate well to this game's engine.

The multi-core results are equally robust: Cinebench R23 multi-core scores 34731, and PassMark multi-thread scores 40849. These figures suggest the CPU has ample headroom for background tasks, scenery loading, and the simulation's physics calculations, which do utilize multiple threads. However, the data from the measured FPS indicates that this CPU power is not the limiting factor in most scenarios. At 1080p Low, the 106 FPS result is likely close to the CPU's practical limit for this game's engine, but at higher resolutions, the GPU takes over as the constraint.

The CPU's nearest rivals in synthetic benchmarks include the AMD EPYC 8124P (0.1% slower), AMD Ryzen 9 5950X (0.2% faster), Intel Core i7-14700 (0.4% slower), and Intel Core i9-13900F (0.7% faster). These deltas are all within 1%, meaning the 235HX delivers desktop-class compute performance in a mobile package. For Microsoft Flight Simulator, this means the CPU will not be a weak link in most configurations; the 24 MB of shared L3 cache and dual-channel DDR5 memory support (102.4 GB/s bandwidth) provide adequate data throughput for the game's streaming-heavy world rendering.

The 3 nm process node from TSMC, with 17,800 million transistors on a 243 mm² die, contributes to the CPU's efficiency and sustained boost behavior. While the 55 W TDP is modest for a high-core-count mobile chip, the benchmark scores suggest it maintains competitive performance without excessive power draw. In practical terms for this game, the CPU's role is to feed the GPU with draw calls and handle the simulation logic; the data shows it succeeds admirably at 1080p but cannot overcome the GPU's limitations at 1440p and 4K.

GPU Role

The NVIDIA GeForce RTX 4060 Mobile is built on the AD107 chip using a 5 nm process from TSMC, with 18,900 million transistors on a 159 mm² die. The GPU features 3072 shading units, 96 texture mapping units, and 48 raster output units, along with 24 RT cores and 96 tensor cores. The boost clock of 1890 MHz and base clock of 1545 MHz, combined with 8 GB of GDDR6 memory on a 128-bit bus (256.0 GB/s bandwidth), define its performance envelope. The FP32 throughput of 11.61 TFLOPS places it as a mid-range mobile part, and the benchmark data confirms this positioning.

The GPU's PassMark G3D score of 17469 puts it in the 67th percentile of all GPUs, with nearest rivals including the desktop RTX 2080 (0.7% faster), AMD Radeon RX 7700 XT (0.8% slower), Intel Arc B580 (1.3% faster), and RTX 5060 Mobile (1.3% slower). This tight clustering around the 22500-23000 score range indicates the 4060 Mobile competes with desktop parts from previous generations and current mid-range offerings. For Microsoft Flight Simulator, this translates to the measured FPS results: capable at 1080p and 1440p, but struggling at 4K.

The 8 GB VRAM capacity is sufficient for this game at the tested settings, as evidenced by the fact that even 4K Ultra produces a playable (if not smooth) 35 FPS average without apparent memory-related stuttering. The memory bandwidth of 256.0 GB/s is adequate for 1080p and 1440p workloads, but the 4K results suggest the GPU's compute throughput, not memory bandwidth, is the limiting factor. The pixel rate of 90.72 GPixel/s and texture rate of 181.4 GTexel/s are modest figures that explain the steep performance drop when pixel count quadruples from 1080p to 4K.

The GPU's DirectX 12 Ultimate support (12_2) ensures full feature compatibility with Microsoft Flight Simulator's modern rendering pipeline. The PassMark DirectX 12 score of 73, while not directly comparable to in-game performance, indicates the GPU handles modern API workloads efficiently. The boost behavior at 115 W TDP allows sustained performance without thermal throttling in most mobile chassis, which is critical for a simulator that can run for extended sessions.

Q: How does this combo rank among all tested systems for this game?

A: The combination ranks 2268 out of 3714 tested combos, placing it in the 61st percentile. This means about 39% of tested systems perform better, while 61% perform worse — a solid mid-pack result for a mobile CPU and GPU pairing.

How This Combo Ranks

The combo rank of 2268 out of 3714 tested combinations places this system in the upper-middle tier for Microsoft Flight Simulator. The 61st percentile ranking means that while the majority of tested systems perform worse, there is still a substantial number of more capable configurations. This positioning is consistent with the hardware's specifications: the CPU's 91st percentile ranking among all processors is offset by the GPU's more modest 67th percentile standing. The GPU is the weaker link in this pairing, and the game's performance reflects that imbalance.

Compared to the CPU's nearest rivals in synthetic benchmarks, the 235HX holds its own — the 0.2% difference from the Ryzen 9 5950X and 0.7% difference from the i9-13900F are negligible in real-world gaming. The GPU's nearest rivals show a similar clustering, with the RTX 4060 Mobile sitting within 1.3% of desktop-class parts. This suggests that the combo's ranking is primarily determined by the GPU's absolute performance level rather than any pairing inefficiency.

The measured FPS data supports this interpretation: at 1080p, the system achieves frame rates that would satisfy most users, but the 4K results fall below 40 FPS at High and Ultra settings. In the context of 3714 tested combos, this places the system in a position where it outperforms many older or lower-tier configurations but trails systems with higher-end GPUs. The 1440p results (48-86 FPS across settings) are the most competitive, suggesting that this resolution is where the combo offers its best relative performance.

Measured FPS Breakdown

The complete measured FPS data across all resolutions and settings is as follows:

3840x2160 (4K):

• Low: 63 FPS average
• Medium: 49 FPS average, 42 FPS minimum, 57 FPS maximum
• High: 37 FPS average
• Ultra: 35 FPS average

2560x1440 (1440p):

• Low: 86 FPS average
• Medium: 67 FPS average, 57 FPS minimum, 77 FPS maximum
• High: 50 FPS average
• Ultra: 48 FPS average

1920x1080 (1080p):

• Low: 106 FPS average
• Medium: 83 FPS average, 70 FPS minimum, 95 FPS maximum
• High: 62 FPS average
• Ultra: 59 FPS average

The data reveals several important patterns. First, the Medium settings consistently provide the highest minimum frame rates among the tested settings at each resolution (42 FPS at 4K, 57 FPS at 1440p, 70 FPS at 1080p), indicating better frame pacing than Low, High, or Ultra. Second, the jump from Medium to High costs significantly more performance than the jump from High to Ultra: at 1440p, Medium to High costs 17 FPS, while High to Ultra costs only 2 FPS. This suggests diminishing returns at the highest quality settings.

Third, the resolution scaling from 1080p to 1440p at High settings costs 12 FPS (62 to 50, a 19% drop), while 1440p to 4K at High costs 13 FPS (50 to 37, a 26% drop). The proportionally larger drop at higher resolutions confirms the GPU's increasing bottleneck. Finally, the 1080p Low result of 106 FPS represents the system's peak performance ceiling, likely constrained by the CPU's single-threaded rendering capabilities in this game engine.

The minimum frame rates recorded only for Medium settings (70 FPS at 1080p, 57 FPS at 1440p, 42 FPS at 4K) provide insight into worst-case scenarios. The 42 FPS minimum at 4K Medium suggests that even in demanding scenes with heavy scenery or weather effects, the system maintains playable frame rates. At 1080p, the 70 FPS minimum ensures smooth operation even during complex approach and landing sequences. These minimums are notably higher than the averages for High and Ultra settings at the same resolutions, reinforcing Medium as the recommended quality setting for a consistent experience.
