Microsoft Flight Simulator

Microsoft Flight Simulator is an outlier in the PC benchmarking world. Unlike fast-twitch shooters, this sim demands immense processing power for physics, weather, and AI traffic, while also pushing the GPU to render dense photogrammetry and terrain. The data for this combination—Intel Core Ultra 7 265K paired with AMD Radeon RX 6700 XT—shows a system that is heavily balanced, with performance scaling that reveals exactly where the bottleneck shifts across resolutions.

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

The Intel Core Ultra 7 265K is a 20-core, 20-thread processor based on the Arrow Lake architecture, built on a 3 nm process. It runs at a base clock of 3.90 GHz and boosts up to 5.50 GHz. For a flight sim, this is a strong foundation because the game's simulation logic—aircraft systems, wind modeling, and ground traffic—tends to scale with raw single-thread speed. The 5.50 GHz boost clock helps ensure that the main simulation thread isn't a limiting factor.

In synthetic benchmarks, this CPU sits at the 97th percentile against all CPUs, with an average benchmark score of 79,102. Its nearest rival, the Intel Core Ultra 7 265KF, scores 79,240, a mere 0.2% difference, confirming the 265K is essentially at parity with its KF sibling. The Core i9-14900K scores 79,824, which is 0.9% higher, showing that the 265K is within a rounding error of the previous flagship. The data suggests the 265K is a top-tier performer for this title.

Looking at the measured FPS data, the CPU's influence is most visible at 1080p. At 1920x1080 with Low settings, the system hits 119.1 FPS. This is the highest frame rate in the entire dataset, and it demonstrates that the 265K can feed the GPU quickly enough to avoid a hard cap. Even when the settings jump to Ultra, the 1080p average only drops to 70.1 FPS, which is only a slight dip from the High preset. This indicates that the CPU is holding up its end of the bargain; the frame rate is not collapsing due to processor limitations.

The CPU's memory bandwidth of 102.4 GB/s and support for DDR5 also play a role. Flight sims are notorious for loading large amounts of terrain data, and the 30 MB of shared L3 cache helps keep frequently accessed data close to the cores. While the fact pack doesn't provide per-core frame times, the consistency of the 1080p results—where the CPU has the most influence—suggests the 265K is a reliable partner, avoiding the stutters that can plague weaker processors in this genre.

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

The AMD Radeon RX 6700 XT is a RDNA 2.0 graphics card with 12 GB of GDDR6 memory on a 192-bit bus, delivering 384.0 GB/s of bandwidth. Its boost clock is 2581 MHz, and it offers 13.21 TFLOPS of FP32 compute. In the current GPU landscape, this card sits at the 77th percentile, which is respectable but not top-tier. Its average benchmark score is 33,721, placing it just 0.7% behind the AMD Radeon RX 6800, which scores 33,493. The data shows it is also 1.3% ahead of the NVIDIA RTX A5000, but that is a workstation card, not a direct gaming rival.

In Microsoft Flight Simulator, the GPU's primary job is to render the world. At 4K with Ultra settings, the system produces only 38.7 FPS. This low number is a direct result of the RX 6700 XT's compute limits, not a lack of VRAM. The 12 GB frame buffer is adequate for this game at 4K, as the performance drop from High to Ultra is only 3.3% (40 FPS to 38.7 FPS), which is a small penalty for the extra visual fidelity. The 384.0 GB/s memory bandwidth is sufficient to feed the 2560 shading units, but the 13.21 TFLOPS is simply not enough to brute-force 4K Ultra in this title.

The GPU's role becomes clearer when looking at the 1440p results. At 2560x1440 with Ultra settings, the average FPS is 54.2. This is a 40% improvement over 4K Ultra, showing that the card is still the limiting factor but has more headroom at lower pixel counts. The card's 64 ROPs and 413.0 GTexel/s texture rate are being pushed hard, but the architecture handles the load predictably. The data indicates this GPU is a solid 1080p and 1440p performer, but it runs out of steam at 4K with high presets.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured data provides a clear picture of performance across three resolutions and four presets.

At 1920x1080, the system is at its strongest. The Low preset delivers 119.1 FPS, which is the highest score in the entire dataset. The Medium preset drops to 96.1 FPS, a 19.3% reduction. The High preset averages 70.4 FPS, and the Ultra preset averages 70.1 FPS. The difference between High and Ultra is negligible at only 0.4%, suggesting that the Ultra preset's extra effects are not heavily taxing the GPU at this resolution.

At 2560x1440, the frame rates become more demanding. The Low preset averages 98.7 FPS, which is a solid result for 1440p. The Medium preset hits 75.6 FPS, while the High preset averages 58.5 FPS. The Ultra preset drops to 54.2 FPS. The gap between Medium and High is 22.6%, indicating a significant visual quality jump that costs performance.

At 3840x2160, the GPU begins to struggle. The Low preset averages 71.6 FPS, which is still playable. The Medium preset drops to 54.2 FPS, and the High preset averages 40 FPS. The Ultra preset is the lowest at 38.7 FPS. This resolution shows the most dramatic scaling, with a 45.9% drop from Low to Ultra.

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

The scaling from 1080p to 4K reveals a textbook GPU-bound scenario. At Low settings, the system drops from 119.1 FPS at 1080p to 71.6 FPS at 4K, a 39.9% decrease. At Ultra settings, the drop is from 70.1 FPS at 1080p to 38.7 FPS at 4K, a 44.8% decrease. This consistent drop of roughly 40-45% when quadrupling the pixel count indicates that the RX 6700 XT is the primary bottleneck.

If the CPU were the limiting factor, we would expect the 1080p and 1440p results to be closer together, because the CPU workload doesn't change much with resolution. Instead, we see a 17.3% drop from 1080p High (70.4 FPS) to 1440p High (58.5 FPS), and a 31.6% drop from 1440p High to 4K High (40 FPS). The scaling is not linear with pixel count, but the steep decline at 4K confirms the GPU is saturated.

This has practical implications. At 1080p, the system has headroom to spare, as evidenced by the 119.1 FPS Low result. At 1440p, the system is well-balanced, with the CPU and GPU working in harmony. At 4K, the GPU is clearly overmatched, and users should expect to dial back settings to maintain playability. The data suggests that the 265K is not holding the GPU back at any resolution; the GPU is simply running out of compute power.

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

For a smooth, consistent experience, the Medium preset at 2560x1440 is the sweet spot. The 75.6 FPS average is well above the 60 FPS threshold that most simmers prefer, and it provides a significant visual upgrade over the Low preset. The High preset at this resolution drops to 58.5 FPS, which is still playable, but the Medium preset offers a better margin for complex scenarios like flying over dense cities.

If you prefer 1080p, the High preset at 1920x1080 is the recommended choice. At 70.4 FPS, it delivers a smooth experience with good visuals. The Ultra preset at 1080p is essentially identical at 70.1 FPS, so there is no reason to avoid it if you want maximum fidelity. However, the 0.4% difference suggests the Ultra preset's extra effects are negligible, so High is the more efficient option.

At 4K, the Low preset at 3840x2160 is the only playable option, averaging 71.6 FPS. The Medium preset at 54.2 FPS is borderline, and the High and Ultra presets (40 FPS and 38.7 FPS) are too choppy for a simulator that requires precise control. If 4K is a must, stick with Low settings to keep the frame rate stable.

For the best balance of visuals and performance, the data points to the Medium preset at 2560x1440 as the overall winner. It provides a 39.5% FPS boost over the High preset at the same resolution, while offering a substantial improvement in detail over the Low preset. The 75.6 FPS average gives you enough headroom to handle the game's most demanding moments without dipping into stutter territory.
