Microsoft Flight Simulator

Microsoft Flight Simulator is a unique stress test for any PC, demanding both a high-end CPU for its complex simulation logic and a top-tier GPU for rendering vast landscapes. The data for the Intel Core i7-14700KF paired with the NVIDIA GeForce RTX 5090 shows a system that is exceptionally capable, but the performance scaling across resolutions reveals a nuanced story about where the bottleneck lies and how to best configure the game.

Resolution Scaling

The measured FPS data shows a clear and predictable trend: as resolution increases, frame rates drop, but the rate of that drop tells us about the limiting component. At 1080p with Low settings, the combo achieves 233.5 FPS. Moving to 1440p Low drops that to 194 FPS, a reduction of 39.5 FPS. At 4K Low, the average falls to 139 FPS, another 55 FPS lower. This indicates that even at the lowest settings, the GPU is being taxed heavily by the sheer pixel count at higher resolutions.

However, the scaling pattern changes dramatically when we look at the Ultra preset. At 1080p Ultra, the system hits 132 FPS. At 1440p Ultra, it drops to 107.8 FPS, and at 4K Ultra, it falls further to 76.9 FPS. The performance hit from 1080p to 1440p is a 24.2 FPS drop, and from 1440p to 4K is a 30.9 FPS drop. While these are significant, the relative drop is less severe than at Low settings. This suggests that at Ultra settings, the workload is more balanced, with the CPU and GPU both contributing to the frame time.

The data indicates that at 1080p, the Core i7-14700KF is doing a lot of the heavy lifting. The jump from 233.5 FPS at Low to 132 FPS at Ultra (a 101.5 FPS difference) shows that the graphics card is still scaling with settings, but the CPU is likely preventing even higher frame rates at Low. As you move to 4K, the RTX 5090 becomes the primary limiting factor. The gap between Low (139 FPS) and Ultra (76.9 FPS) narrows to a 62.1 FPS difference, showing that pixel throughput is dominating the GPU's resources. This is a classic sign of a system that is CPU-bound at lower resolutions and GPU-bound at 4K.

GPU Role

The NVIDIA GeForce RTX 5090 is a powerhouse, and its specifications support the high frame rates seen in the data. Its 32 GB of GDDR7 memory on a 512-bit bus provides a massive 1.79 TB/s of bandwidth. This is critical for a game like Microsoft Flight Simulator, which streams vast amounts of terrain and texture data. The data shows that even at 4K Ultra, the card never appears to run out of memory bandwidth, as the frame rates remain consistent.

The GPU's clock speeds are substantial, with a base clock of 2017 MHz and a boost clock of 2407 MHz. These high clocks contribute to its raw compute power, which is rated at 104.8 TFLOPS for FP32 operations. This immense processing capability is what allows it to render the complex lighting, shadows, and weather effects in the simulator at playable frame rates. The benchmark results reflect this, with a Passmark G3D score of 39650, placing it in the 94th percentile of all GPUs.

However, the data suggests that at 1080p, the GPU's potential is not fully utilized. The core count of 21760 shading units is massive, but at lower resolutions, the CPU is likely the primary bottleneck. This is why the frame rate difference between Low and Ultra at 1080p is 101.5 FPS, as the GPU has headroom to render more complex frames. At 4K, the GPU is pushed to its limits, and the difference between Low and Ultra narrows to 62.1 FPS, showing a more balanced workload between the CPU and GPU.

Settings Recommendations

Based on the measured data, the best settings depend heavily on your display and your preference for frame rate versus visual fidelity.

For users with a 1080p high-refresh-rate monitor (e.g., 144Hz or 240Hz), the High preset is the sweet spot. It delivers an average of 141.4 FPS, which is perfectly suited for a 144Hz display, and it offers a significant visual improvement over Medium. If you have a 240Hz display and prioritize maximum smoothness, the Medium preset at 189.8 FPS is the better choice, as the jump to Low (233.5 FPS) offers diminishing visual returns.

For 1440p displays, the High preset is highly recommended. At 111.5 FPS, it exceeds the 100 FPS mark, providing a very smooth experience. The Ultra preset is also viable at 107.8 FPS, and given the additional visual polish it provides for a simulator, it is arguably the best choice for this resolution. The difference between High and Ultra here is only 3.7 FPS, making Ultra the clear winner for image quality.

At 4K resolution, the choice is more about personal preference. The High preset at 80.2 FPS is a great balance, offering high detail with a solid frame rate. The Ultra preset at 76.9 FPS is almost as fast, and for a game like Microsoft Flight Simulator, the extra visual detail at Ultra will be more noticeable than the 3.3 FPS loss. Therefore, 4K Ultra is the recommended setting for this system, as it provides the best possible image quality while still maintaining a playable and consistent frame rate above 75 FPS.
