Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, one where the sprawling world geometry and live weather systems stress both the processor and the graphics card in ways few other games manage. In this analysis, we examine the measured performance of the Intel Core Ultra 9 290K Plus paired with the AMD Radeon RX 6700 XT. The data reveals a configuration that is heavily balanced toward the CPU, with the GPU acting as the primary bottleneck at higher resolutions, yet the system still manages to deliver playable frame rates across a wide spectrum of settings.

Resolution Scaling

The measured FPS data for this combo shows a clear and predictable pattern: as resolution increases, average frame rates drop, but the rate of that drop is more dramatic between 1440p and 4K than between 1080p and 1440p. Moving from 1920x1080 to 2560x1440 on High settings, the average FPS falls from 71 to 57, a reduction of roughly 19.7%. However, the subsequent step from 2560x1440 to 3840x2160 on the same settings sees the average FPS drop from 57 to 42, a steeper decline of approximately 26.3%. This non-linear scaling is a classic indicator that the graphics card is becoming the limiting factor as pixel count grows.

This pattern is even more pronounced when examining the Low preset. At 1080p Low, the system achieves 121 FPS, which drops to 97 FPS at 1440p, a 19.8% decrease. But the jump to 4K Low yields 72 FPS, a 25.8% reduction from the 1440p figure. The fact that the percentage loss accelerates at higher resolutions suggests that the AMD Radeon RX 6700 XT is running out of raw pixel-pushing power. The data implies that while the CPU has headroom to feed frames at 1080p, the GPU's 12 GB of VRAM and 384.0 GB/s memory bandwidth are being saturated when the render target expands to 3840x2160.

What this scaling tells us is that the system is not perfectly balanced for 4K gaming. The 42 FPS average at 4K High is borderline playable, but the 40 FPS at 4K Ultra suggests that the GPU is struggling to maintain fluid motion. The fact that the 1080p Low score of 121 FPS is more than double the 4K Ultra score of 40 FPS highlights the extreme sensitivity of this game to resolution. For users targeting 4K, the data suggests that the RX 6700 XT is the definitive bottleneck, as the CPU's performance is likely not being fully utilized at those pixel densities.

How This Combo Ranks

In the grand scheme of tested hardware combinations for Microsoft Flight Simulator, this pairing sits at rank 1524 out of 2996 combos. This places it in the 49th percentile, meaning it outperforms roughly half of all tested configurations. While this might sound mediocre, it is important to contextualize this rank with the specific components involved. The CPU, the Intel Core Ultra 9 290K Plus, is a top-tier processor with a 96th percentile ranking against all CPUs, while the GPU, the AMD Radeon RX 6700 XT, sits at a more modest 72nd percentile against all GPUs.

The disparity in component percentiles explains the mid-pack combo rank. The CPU is powerful enough to drive high frame rates, but the GPU holds the system back from reaching the upper echelons of the leaderboard. This is a classic case of a bottlenecked system, where the graphics card's performance ceiling is the defining factor. The data suggests that if this CPU were paired with a more powerful GPU, the combo rank would improve significantly, as the processor's high single-thread and multi-thread scores would be able to push more frames.

Looking at the nearest rivals for the CPU, the Intel Core Ultra 9 285K scores 0.2% lower in average benchmarks, while the AMD EPYC 4584PX is 1.1% lower. This indicates that the 290K Plus is at the very top of the performance heap for its socket. For the GPU, the NVIDIA GeForce RTX 4070 Mobile is a statistical tie (0% delta), and the RTX 3090 is 0.5% better. This shows that the RX 6700 XT's average benchmark score is competitive with some high-end parts, but in this specific game, its 4K performance is clearly the limiting factor.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture and features 12 GB of GDDR6 memory on a 192-bit bus, providing 384.0 GB/s of bandwidth. Its boost clock is listed at 2581 MHz, with a game clock of 2424 MHz. In Microsoft Flight Simulator, the GPU's role is to render the vast landscapes, detailed aircraft models, and dynamic weather effects. The data shows that this card is capable of delivering playable frame rates at 1080p and 1440p, but it is clearly overburdened at 4K.

The VRAM capacity of 12 GB is a significant factor. At 4K with Ultra settings, the game likely requires a substantial amount of memory for textures and geometry. The fact that the average FPS at 4K Ultra drops to 40 suggests that the GPU is not only compute-bound but may also be hitting memory limitations. The 384.0 GB/s bandwidth is sufficient for 1080p and 1440p, but at 4K, the demand for texture data outpaces the card's ability to fetch it from VRAM.

The GPU's benchmark scores reinforce this narrative. Its Passmark G3D score is 19786, and its 3DMark Steel Nomad DX12 score is 2435. These figures place it in the 72nd percentile of all GPUs, indicating it is a solid mid-range performer. However, the measured FPS in this game at 4K (42 FPS High, 40 FPS Ultra) suggests that the card is only able to utilize its full potential at lower resolutions. The data shows a clear correlation: the higher the resolution, the more the GPU becomes the sole determinant of performance, with the CPU's power going unused.

Measured FPS Breakdown

The measured FPS data provides a comprehensive picture of this combo's performance across three resolutions and four settings presets. Starting at 1920x1080, the system shows strong results. On Low settings, it averages 121 FPS, dropping to 94 FPS on Medium (with a min of 80 and max of 108), 71 FPS on High, and 67 FPS on Ultra. This spread of 54 FPS between Low and Ultra shows that the CPU is capable of pushing high frame rates when the GPU is not the constraint, but the GPU still manages to keep up without a dramatic collapse.

Moving to 2560x1440, the impact of increased pixel count is clear. Low settings yield 97 FPS, Medium averages 76 FPS (min 64, max 87), High drops to 57 FPS, and Ultra falls to 54 FPS. The delta between Low and Ultra is now 43 FPS, showing that the GPU is starting to struggle. The 1440p Medium result of 76 FPS is particularly interesting, as it shows a playable experience with a decent frame buffer, but the High and Ultra presets are approaching the lower limits of smooth gameplay.

At 3840x2160, the GPU's limitations become stark. Low settings average 72 FPS, which is still playable, but Medium drops to 56 FPS (min 47, max 64), High to 42 FPS, and Ultra to 40 FPS. The difference between Low and Ultra at 4K is only 32 FPS, indicating that even with significant graphical sacrifices, the GPU cannot deliver high frame rates. The 4K Medium result of 56 FPS is perhaps the most balanced point, offering a playable experience without dropping to the sub-45 FPS territory of High and Ultra. The data clearly shows that this card is not designed for 4K Ultra settings in this title.

CPU Role

The Intel Core Ultra 9 290K Plus is a 24-core, 24-thread processor with a base clock of 3.70 GHz and a boost clock of 5.80 GHz. It features 36 MB of shared L3 cache and supports DDR5 memory. Its benchmark scores are exceptional, with a Cinebench R23 multi-core score of 51731 and a single-core score of 7303. The Passmark multi-thread score is 60860, and its single-thread score is 4823. These numbers place it in the 96th percentile of all CPUs, making it one of the fastest processors available.

In Microsoft Flight Simulator, the CPU is responsible for simulating the physics, flight models, and the complex scenery streaming system. The data suggests that this CPU is more than capable of handling these tasks. The high single-core performance is crucial for the main game thread, and the massive multi-core throughput helps with background tasks like loading terrain data. The fact that the system achieves 121 FPS at 1080p Low indicates that the CPU is not a bottleneck at that resolution; the GPU is simply able to keep up with the processor's output.

However, at higher resolutions, the CPU's influence wanes. The frame rates drop in a way that is inversely proportional to the increase in pixel count, which is a hallmark of GPU limitation. The CPU's benchmark scores, such as the Passmark data compression score of 698346 and the floating-point math score of 214760, are not reflected in the 4K results. This implies that while the CPU is exceptionally powerful, its performance headroom is wasted when the GPU is struggling to render frames. The data indicates that for this game, the CPU is a future-proofing investment, but its full potential is only realized with a more powerful graphics card.

Settings Recommendations

For the best experience with this hardware, the data points to a clear strategy: prioritize resolution over graphical fidelity. At 1920x1080, users can comfortably run the High preset at 71 FPS or even Ultra at 67 FPS for a visually rich experience. However, given the CPU's power, the Low preset at 121 FPS is only recommended for competitive or high-refresh-rate scenarios, which are less common in a flight sim.

At 2560x1440, the Medium preset is the sweet spot, offering 76 FPS with a reasonably tight frame time variance (min 64, max 87). The High preset at 57 FPS is still playable, but the drop below 60 FPS might be noticeable to some users. The Ultra preset at 54 FPS is not recommended, as the visual gains over High are marginal but the performance cost is significant.

For 4K, the options are more limited. The Low preset at 72 FPS is the only setting that guarantees a smooth experience, but it sacrifices many visual details that make this game stand out. The Medium preset at 56 FPS is the best compromise, offering a playable frame rate while retaining some of the game's visual fidelity. The High and Ultra presets, at 42 and 40 FPS respectively, should be avoided unless the user is willing to accept stutter and a less fluid experience. The data suggests that 1440p Medium is the overall best experience, as it balances the GPU's capabilities with the CPU's potential, delivering a smooth and visually pleasing result.
