Microsoft Flight Simulator

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

The Intel Core Ultra 5 235 is a 14-core, 14-thread processor from the Arrow Lake-S family, built on TSMC's 3 nm process. Its base clock of 3.40 GHz can reach a 5.00 GHz boost, and it carries 24 MB of shared L3 cache alongside 3 MB of L2 per core. For a flight simulator like Microsoft Flight Simulator, which relies heavily on single-thread performance for simulation logic and physics calculations, this processor's boost clock and architectural efficiency are critical.

The CPU's benchmark profile reinforces its capability in this title. In Cinebench R23, it scores 2,085 points single-core and 14,769 points multi-core. The single-core result places it in the upper echelon of desktop processors, which matters because Microsoft Flight Simulator's frame pacing often depends on the main simulation thread. The multi-core score of 14,769 indicates substantial parallel throughput for background tasks like terrain streaming and AI traffic, though the game's core demand is not fully parallel.

Relative to its nearest rivals, the Core Ultra 5 235 sits in a tight cluster. Its average benchmark score of 46,062 is within 0.1% of the AMD Ryzen AI 9 HX 375 (46,030) and within 0.2% of the AMD EPYC 4364P (45,970). The Intel Core i9-13900HX (46,098) is just 0.1% ahead. This means that in synthetic workloads, the Core Ultra 5 235 trades blows with these competitors, and in a game that is sensitive to CPU single-thread performance, the differences are likely to be within a few frames per second.

The 89th percentile ranking against all CPUs further confirms that this processor is positioned well above average, but not at the absolute top. For Microsoft Flight Simulator, the data suggests that the CPU will not be the primary bottleneck at higher resolutions, but at 1080p with lower settings, its performance ceiling will be tested. The 14 threads are not hyperthreaded, which is an interesting design choice, but the high boost clock compensates in lightly threaded workloads.

Given the 65 W TDP and dual-channel DDR5 memory support with 102.4 GB/s bandwidth, the Core Ultra 5 235 is a balanced desktop part. The measured FPS data shows that at 1080p Low, the combo reaches 164 FPS, which indicates strong CPU headroom. However, at 4K Ultra, the frame rate drops to 55 FPS, signaling that the GPU becomes the limiting factor as resolution and settings scale up.

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

The AMD Radeon RX 9070 XT is built on the RDNA 4.0 architecture, using the Navi 48 chip fabricated on TSMC's 4 nm process. It features 16 GB of GDDR6 memory on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The GPU's base clock is 1660 MHz, with a boost clock of 2970 MHz and a game clock of 2400 MHz. Memory runs at 2518 MHz, effective 20.1 Gbps.

For Microsoft Flight Simulator, which streams vast amounts of terrain and scenery data, the 16 GB VRAM capacity is significant. The game can consume substantial memory at high resolutions and Ultra settings, and the 16 GB buffer helps avoid texture swapping that could cause stutters. The 644.6 GB/s bandwidth also supports rapid data transfer from VRAM to the rendering pipeline, which is essential for maintaining smooth frame rates during fast camera movements over dense scenery.

The GPU's compute specifications include 4,096 shading units, 256 TMUs, and 128 ROPs. With 64 ray tracing cores, the RX 9070 XT can handle the game's ray-traced effects, though Microsoft Flight Simulator's use of RT is limited. The FP32 performance of 48.66 TFLOPS indicates strong rasterization capability, which is the primary workload in this simulator.

In benchmark terms, the RX 9070 XT scores 26,795 in Passmark G3D and 7,260 in 3DMark Steel Nomad DX12. Its average benchmark score is 13,543, which places it at the 55th percentile among all GPUs. This is a mid-to-upper tier standing, and the nearest rivals in terms of average score are surprisingly older parts: the AMD Radeon HD 7770M (13,536, 0.1% behind), NVIDIA GeForce GTX 570 (13,515, 0.2% behind), and NVIDIA P106-090 (13,470, 0.5% behind). These comparisons are based on aggregate scores that include older workload types, so they do not directly translate to modern gaming performance. The RX 9070 XT's DirectX 12 score of 78 in Passmark is more indicative of its current API performance, though it is a synthetic metric.

The measured FPS data shows the GPU's scaling behavior. At 1080p Low, the combo achieves 164 FPS, which drops to 96 FPS at High settings. At 4K, the spread is from 98 FPS at Low down to 55 FPS at Ultra. This scaling pattern reveals that the GPU is the dominant factor at higher resolutions and settings, as the frame rate decreases by roughly 44% from 1080p Low to 4K Low, and by 42% from 1080p Ultra to 4K Ultra. The VRAM capacity ensures that even at 4K Ultra, the game does not exceed the 16 GB buffer, allowing the GPU to focus on processing rather than memory management.

# Settings Recommendations — which preset gives the best experience per the measured rows

Analyzing the measured FPS rows across all resolutions and settings, the data shows a clear trade-off between visual fidelity and frame rate. The Ultra preset consistently delivers the lowest average FPS at each resolution: 92 FPS at 1080p, 74 FPS at 1440p, and 55 FPS at 4K. These are playable, but the 4K Ultra result of 55 FPS approaches the threshold where motion smoothness can suffer in a simulator that requires precise camera control.

The High preset offers a better balance. At 1080p, it achieves 96 FPS, which is only 4 FPS less than Ultra but with a significant reduction in graphical effects. At 1440p, High delivers 78 FPS, which is 4 FPS higher than the Ultra preset's 74 FPS at the same resolution. At 4K, High hits 57 FPS, just 2 FPS above Ultra. The consistency of High settings across resolutions suggests it is the most stable preset for maintaining frame rates above 60 FPS at 1080p and above 55 FPS at 4K.

Medium settings provide a substantial FPS boost. At 1080p, Medium averages 128 FPS with a minimum of 109 FPS and maximum of 147 FPS. At 1440p, it averages 103 FPS with min/max of 88/119 FPS. At 4K, Medium reaches 76 FPS with min/max of 65/88 FPS. These figures indicate that Medium is the sweet spot for high refresh rate monitors, especially at 1440p where the 103 FPS average is well above the 60 FPS threshold, and the minimum of 88 FPS ensures minimal stuttering.

Low settings unlock the highest frame rates, reaching 164 FPS at 1080p, 133 FPS at 1440p, and 98 FPS at 4K. However, the visual compromise is substantial, and for a game that emphasizes scenery detail, Low settings may detract from the experience.

The best experience per the measured rows depends on the target display. For 1080p users with a 144 Hz monitor, Medium at 128 FPS is the optimal choice. For 1440p users with a 60 Hz display, High at 78 FPS provides excellent visual quality without exceeding refresh rate limits, while Medium at 103 FPS suits 100 Hz+ panels. For 4K users, Medium at 76 FPS is the only preset that comfortably exceeds 60 FPS, making it the recommended choice despite the visual reduction from High or Ultra.

# FAQ

Q: Does the CPU or GPU limit performance more in Microsoft Flight Simulator?

A: The data shows that the GPU becomes the limiting factor at higher resolutions and settings. From 1080p Low (164 FPS) to 4K Low (98 FPS), the frame rate drops by 40%, while from 1080p Ultra (92 FPS) to 4K Ultra (55 FPS), it drops by 40% as well.

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

The measured FPS data reveals distinct scaling patterns across resolutions, which indicate where the bottleneck lies. At Low settings, the frame rate drops from 164 FPS at 1080p to 133 FPS at 1440p (a 19% reduction) and then to 98 FPS at 4K (a 26% reduction from 1440p). The total drop from 1080p to 4K is 40%. This pattern suggests that even at Low settings, the GPU is still the primary limiter, as the CPU's 14 cores and 5.00 GHz boost clock provide sufficient headroom.

At Medium settings, the scaling is similar: 128 FPS at 1080p, 103 FPS at 1440p (a 20% reduction), and 76 FPS at 4K (a 26% reduction from 1440p). The total drop is 41%. The consistency of these percentage reductions across Low and Medium settings indicates that the GPU's rendering workload scales predictably with pixel count, and the CPU is not introducing additional bottlenecks.

At High settings, the FPS drops from 96 FPS at 1080p to 78 FPS at 1440p (a 19% reduction) and then to 57 FPS at 4K (a 27% reduction from 1440p). The total drop is 41%. Ultra settings show a similar trend: 92 FPS at 1080p, 74 FPS at 1440p (a 20% reduction), and 55 FPS at 4K (a 26% reduction from 1440p). The total drop is 40%.

The uniform ~40% FPS drop from 1080p to 4K across all settings is a strong indicator that the GPU is the dominant limiting component in this configuration. If the CPU were the bottleneck, we would expect to see a smaller FPS drop at lower resolutions (where the CPU is more stressed) and a larger drop at higher resolutions (where the GPU takes over). Instead, the near-constant percentage reduction suggests that the RX 9070 XT's rendering throughput is the constraining factor, and the Core Ultra 5 235 is delivering frames fast enough to feed the GPU at all resolutions.

This analysis is further supported by the 4K Medium min FPS of 65 FPS, which is 85% of the average. The GPU's 16 GB VRAM and 644.6 GB/s bandwidth prevent memory-related frame drops, even at 4K, so the scaling is purely due to compute and fill rate limitations. The CPU's Passmark multi-thread score of 37,816 and single-thread score of 4,516 indicate it can handle the simulation's single-threaded logic without causing frame time spikes, as evidenced by the smooth scaling patterns.
