# Microsoft Flight Simulator — Intel Core i7-14700KF + NVIDIA GeForce RTX 5080

The data for Microsoft Flight Simulator with the Intel Core i7-14700KF and NVIDIA GeForce RTX 5080 shows a system that scales predictably across resolutions, with performance headroom shifting from CPU-bound at 1080p to GPU-bound at 4K. The combo ranks 55th out of 1,795 tested combinations, placing it in the top 3% of all tested systems for this title. Across all measured settings, the average frame rates remain playable, though the gap between Low and Ultra presets widens significantly as resolution increases.

Resolution Scaling

From 1080p to 4K, the RTX 5080 paired with the i7-14700KF demonstrates a clear transition in bottleneck behavior. At 1080p with Low settings, the system produces 224.5 FPS, which is the highest measured result across the entire dataset. Moving to 1440p Low drops this to 178.8 FPS, a reduction of roughly 20%, while 4K Low yields 129.2 FPS, another 28% decrease. This pattern indicates that at lower resolutions, the CPU has sufficient headroom to feed the GPU, but the GPU becomes progressively more limiting as pixel count rises.

The High preset tells a similar story but with tighter margins. At 1080p High, the system hits 129.8 FPS; at 1440p High, it falls to 106.2 FPS; and at 4K High, it reaches 74.4 FPS. The scaling from 1080p to 4K at High is approximately 43% lower, which is less severe than the Low preset's 42% drop from 1080p to 1440p alone. This suggests that at High settings, the workload is more balanced between CPU and GPU, with neither component becoming a hard ceiling.

The Ultra preset shows the most pronounced resolution sensitivity. Starting at 123 FPS at 1080p, it drops to 99.3 FPS at 1440p and then to 72.6 FPS at 4K. The 4K Ultra result is only 59% of the 1080p Ultra figure, indicating that the GPU is heavily taxed at maximum settings and high pixel density. Notably, the difference between 4K High (74.4 FPS) and 4K Ultra (72.6 FPS) is just 1.8 FPS, suggesting that the GPU is nearing its limit at 4K regardless of preset, and the additional Ultra effects contribute minimally at this resolution.

Settings Recommendations

For 4K displays, the data favors the High preset as the optimal balance. At 4K High, the system delivers 74.4 FPS, which is comfortably above the 60 FPS threshold for smooth flight simulation. The Medium preset at 4K offers 100.2 FPS, a 35% improvement over High, but the visual fidelity loss from reduced scenery detail and shadow quality may not justify the frame rate gain in a simulation context where visual clarity aids navigation. The Ultra preset at 4K yields 72.6 FPS, only 1.8 FPS below High, meaning the extra GPU load from Ultra settings does not translate into meaningful performance degradation — but it also does not provide a measurable frame rate penalty, making Ultra a viable option at 4K if the user prioritizes maximum visual quality.

At 1440p, the Medium preset (138.6 FPS) provides a strong balance, sitting between the 178.8 FPS Low and 99.3 FPS Ultra results. For users with high-refresh-rate monitors, the Low preset at 1440p (178.8 FPS) could support refresh rates up to 175 Hz, though the visual trade-offs are substantial. The High preset at 1440p (106.2 FPS) is the most versatile choice, offering solid detail with headroom for occasional dips below 100 FPS in dense urban areas or during weather effects.

At 1080p, all presets exceed 120 FPS, making the choice purely visual. The Ultra preset (123 FPS) is the highest fidelity option that still maintains triple-digit frame rates, while the Medium preset (172.8 FPS) offers a significant margin for competitive or fast-paced flying. The Low preset (224.5 FPS) is the only option that approaches the 240 Hz refresh rate territory, but it strips away most of the simulation's visual richness.

This memory capacity and bandwidth are sufficient for Microsoft Flight Simulator's high-resolution textures and streaming scenery, as evidenced by the relatively small frame rate drop from High to Ultra at 4K (74.4 to 72.6 FPS). The GPU's base clock of 2295 MHz and boost clock of 2617 MHz, combined with 10,752 shading units, 336 TMUs, and 112 ROPs, provide the raw throughput needed for the simulation's complex rendering pipeline.

The GPU's FP32 performance of 56.28 TFLOPS and pixel rate of 293.1 GPixel/s contribute to its ability to handle the game's rendering load. The PassMark G3D score of 36,565 and 3DMark Steel Nomad DX12 score of 8,637 indicate solid DirectX 12 performance, which is the primary API for Microsoft Flight Simulator. The GPU's 89th percentile ranking among all GPUs suggests it is a high-end part, but its performance in this game is not as exceptional as the CPU's, which explains why the 4K results show the GPU becoming the limiting factor at Ultra settings.

CPU Role

The Intel Core i7-14700KF provides 20 cores and 28 threads, with a base clock of 3.40 GHz and boost clock of 5.60 GHz. This configuration is well-suited to Microsoft Flight Simulator, which benefits from multi-threaded performance for flight dynamics, weather simulation, and scenery generation. The CPU's Cinebench R23 multi-core score of 44,557 and single-core score of 6,290 demonstrate strong performance in both heavily threaded and lightly threaded workloads. The PassMark multi-thread score of 52,425 and single-thread score of 4,480 reinforce this picture.

The CPU's 33 MB of shared L3 cache and 2 MB per-core L2 cache help reduce memory latency, which is important for the simulation's data streaming. The 96th percentile ranking among all CPUs, with an average benchmark score of 70,104, places it alongside the i7-14700K and Ryzen 9 9950X, both of which have deltaPct values within 0.4% of this processor. The CPU's performance headroom is evident at 1080p, where the Low preset achieves 224.5 FPS, suggesting that the processor is not the primary constraint at lower resolutions. However, at 4K, the CPU's advantage becomes less relevant as the GPU takes over as the bottleneck, with frame rates converging across presets.
