Microsoft Flight Simulator

The Intel Core i7-14700K paired with the AMD Radeon RX 6750 XT delivers a playable, though not flawless, experience in Microsoft Flight Simulator. Benchmark results show a system that is heavily influenced by resolution and settings, with the GPU becoming the primary bottleneck at 4K while the CPU’s strong multi-core performance keeps frame rates respectable at lower resolutions. The data indicates a balanced pairing for 1440p gameplay, but users targeting 4K Ultra will need to manage expectations.

Resolution Scaling

The measured FPS data reveals a clear pattern of diminishing returns as resolution increases. At 1080p with Low settings, the combo achieves 127.3 FPS, which drops to 102.6 FPS at 1440p and 73.8 FPS at 4K. This scaling shows that the RX 6750 XT is the limiting factor when resolution climbs, as the performance penalty from 1080p to 4K is substantial. The gap between 1440p and 4K at Low settings is 28.8 FPS, indicating that the GPU’s 12 GB memory and 432.0 GB/s bandwidth are being saturated at higher pixel counts.

The High settings preset tells a similar story but with lower absolute numbers. At 1080p High, the system produces 72.2 FPS, falling to 58.7 FPS at 1440p and 43.7 FPS at 4K. The drop from 1080p to 4K represents a 39.5% reduction in frame rate, which is significant but not catastrophic. This suggests that while the GPU is stressed at 4K High, the i7-14700K’s 20 cores and 28 threads are still feeding frames adequately, preventing a complete collapse.

Ultra settings exacerbate the GPU bottleneck. The 1080p Ultra result of 71.9 FPS is only slightly lower than the High preset, but 4K Ultra falls to 42.2 FPS. The scaling from 1080p to 4K at Ultra shows a 29.7 FPS drop, which is the largest absolute penalty across all settings. This indicates that the RX 6750 XT’s shading units and RT cores are overwhelmed at 4K with maximum detail, making the CPU’s role secondary at that resolution.

Interestingly, the Medium preset shows the most linear scaling. From 95.5 FPS at 1080p to 78.6 FPS at 1440p and 55.9 FPS at 4K, the performance curve is predictable. This suggests that Medium settings strike a balance where neither component is entirely dominant, allowing for smoother scaling across resolutions. For users prioritizing high frame rates, 1080p Low offers the best headroom, while 1440p Medium provides a solid middle ground for visual fidelity and performance.
