Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title that stresses both the CPU and GPU heavily, and the combination of the Intel Core i5-11400F and AMD Radeon RX 7900 XT produces a clear pattern of performance scaling across resolutions. The data shows a substantial drop in frame rates as resolution increases, which is typical for a flight simulator that relies heavily on rendering vast, detailed landscapes. At 1080p, the average frame rates are exceptionally high across all settings, indicating that the system has ample headroom in less demanding scenarios. Moving to 1440p, the frame rates remain very playable, but the scaling begins to show the GPU taking on more responsibility. At 4K, the performance tightens considerably, showing that the Radeon RX 7900 XT is being pushed to its limits, though it still manages to keep the simulator well within a smooth range for most settings.

Resolution Scaling

The progression from 1920x1080 to 3840x2160 reveals a classic shift in system bottleneck. At the 1080p resolution with High settings, the combo achieves an average of 106.8 FPS. When the resolution is increased to 2560x1440, the average FPS drops to 84.6, which is a reduction of roughly 20.8%. This is a significant but expected decline, showing that the GPU is working harder to render more pixels. The trend continues at 4K, where the High preset yields an average of 58.4 FPS. This represents a 31% drop from the 1440p figure and a 45.3% drop from the 1080p figure. This steep decline indicates that the AMD Radeon RX 7900 XT becomes the primary limiting factor at higher resolutions, as the increase in pixel count demands more from the graphics card's processing power and memory bandwidth.

The data suggests that at 1080p, the Intel Core i5-11400F is more likely to be the limiting component, as the frame rates are so high that the GPU may not be fully saturated. The jump from Low to Medium settings at 1080p shows a smaller performance penalty than the jump from Medium to High, which hints at CPU involvement in handling the simulation's complex world and physics calculations. However, by 4K, the GPU's raw throughput and memory bandwidth of 800.0 GB/s are the dominant factors. The difference between the Low and Ultra presets at 4K is 43.2 FPS, which is a massive gap that underscores how much graphical fidelity taxes the GPU at this resolution. The 58 FPS average at 4K Ultra confirms the GPU's strength, but the 101.2 FPS at 4K Low shows that the headroom is there if the user prioritizes frame rate over visual splendor.

Settings Recommendations

Given the measured data, the optimal settings depend heavily on the target resolution and the user's preference for visual quality versus frame rate smoothness. For 4K gaming, the High preset is the sweet spot, delivering an average of 58.4 FPS. This is just above the standard 60 FPS target, providing a playable experience without the significant performance cost of the Ultra preset, which only yields 58 FPS. The difference between High and Ultra at 4K is minimal in terms of frame rate, but the visual uplift may be worth the slight drop for some users. The Medium preset at 4K, with an average of 81.9 FPS, offers a much more comfortable margin for smoothness and is recommended for those who want to ensure no dips below 60 FPS.

At 1440p, the High preset provides an excellent balance, achieving 84.6 FPS. This is a significant improvement over the 4K result and allows for a smoother experience. The Ultra preset at 1440p, at 81.6 FPS, is nearly identical in performance to High, making it a viable option for maximum visual quality without a harsh penalty. For those with high refresh rate monitors at 1440p, the Medium preset at 110.6 FPS offers a much higher frame rate, which can be beneficial for a more responsive feel. At 1080p, all presets are playable, but the Ultra preset at 99.2 FPS is the recommended choice for the best visual experience, while the Low preset at 155.1 FPS is for users who prioritize maximum frame rates above all else.

How This Combo Ranks

In the grand scheme of tested hardware combinations, this specific pairing of the Intel Core i5-11400F and AMD Radeon RX 7900 XT holds a respectable position. The combo ranks at 392 out of 1795 tested combos in this game, placing it in the top 21.8% of all configurations. This is a strong showing, indicating that the system is well above average for running Microsoft Flight Simulator. The rank is a direct result of the measured FPS data, which shows that the system can handle high resolutions and settings with playable frame rates. The GPU's high benchmark scores, such as a Geekbench OpenCL score of 169834 and a Passmark G3D score of 29009, contribute to its ability to push high frame rates, while the CPU's average benchmark score of 17181 ensures that the simulation's logic is processed efficiently.

The GPU's percentile of 82 among all GPUs and the CPU's percentile of 75 among all CPUs both indicate that this is a high-performing duo. The fact that the combo rank is not higher is likely due to the demanding nature of the game, which can expose weaknesses in any part of the system. However, the data confirms that this setup is a capable one, offering a good balance of processing power and graphical fidelity for a smooth flight simulation experience. The nearest rivals for the CPU include the AMD Ryzen 7 5700U with a delta of 0%, and for the GPU, the NVIDIA GeForce RTX 5080 Mobile with a delta of 0%, showing that the components are competitive within their respective markets.

GPU Role

The AMD Radeon RX 7900 XT plays a central role in delivering the high frame rates seen in the measured data. Its 20 GB of GDDR6 memory is a significant asset, as Microsoft Flight Simulator is known for loading large textures and detailed terrain data. The memory's bandwidth of 800.0 GB/s ensures that this data can be fed to the GPU's 5376 shading units quickly, preventing stutters and maintaining smooth performance. The GPU's boost clock of 2394 MHz is a key factor in its raw processing speed, allowing it to handle the complex geometry and lighting calculations required by the simulator. The data shows that the GPU is the primary driver of performance at higher resolutions, as the frame rate drops are more pronounced from 1440p to 4K than from 1080p to 1440p.

The architecture, RDNA 3.0, is built on a 5 nm process from TSMC, which contributes to its efficiency and high clock speeds. The 84 RT cores also provide hardware support for ray tracing, which can enhance the visual realism of the simulator, though the measured data does not specify whether these features were enabled. The GPU's FP32 performance of 51.48 TFLOPS is a direct indicator of its computational capability, which is necessary for the heavy shader work in the game. The difference in performance between the Low and Ultra presets at any resolution is largely due to the GPU's workload, with Ultra presets requiring more memory and processing power for effects like shadows, reflections, and volumetric clouds. The 58 FPS average at 4K Ultra shows that even a high-end GPU like this is pushed to its limits when all settings are maxed out.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at how this combo performs across different resolutions and settings. At 1920x1080, the system shows its highest performance potential. The Low preset achieves an average of 155.1 FPS, which is the highest figure recorded. The Medium preset follows at 139.2 FPS, and the High preset drops to 106.8 FPS. The Ultra preset at 1080p yields an average of 99.2 FPS, which is still very smooth for a flight simulator. The progression from Low to Ultra at 1080p shows a performance cost of 55.9 FPS, which is a large margin but leaves the system with ample headroom.
