Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, and the combination of the Intel Core i5-11400F with the NVIDIA GeForce RTX 3070 Ti produces a dataset that clearly illustrates the balance between CPU-driven simulation logic and GPU-driven rendering. The measured frames per second across resolutions and presets reveal a system that is capable of smooth flight in most scenarios but requires specific settings to maintain consistency at higher resolutions. This analysis breaks down the measured performance data to determine where this combo sits among tested configurations, what settings to use, and which component limits performance at each stage.

How This Combo Ranks

The pairing of the Intel Core i5-11400F and the NVIDIA GeForce RTX 3070 Ti secures a rank of 1313 out of 3714 tested combos for Microsoft Flight Simulator. This places the configuration in the 65th percentile of all tested systems, indicating that while it is not a top-tier enthusiast setup, it outperforms the majority of combinations in the database. The ranking is influenced by the fact that the simulator's workload is heavily dependent on both the CPU's single-thread performance for flight physics and the GPU's rasterization power for the detailed terrain and weather rendering.

Benchmark results for the individual components show that the CPU's average benchmark score of 17177 places it in the 71st percentile of all CPUs, while the GPU's average score of 29945 places it in the 75th percentile of all GPUs. The combination of two components that are both above the 70th percentile in their respective fields results in a cohesive system that avoids severe bottlenecking in most scenarios. The data shows that the CPU's nearest rival, the AMD EPYC 7H12, has an average score of 17120, which is only 0.3% lower, while the Intel Core i5-12450H scores 17239, a 0.4% margin above. This indicates that the i5-11400F is positioned in a dense cluster of comparable processors, meaning that the overall combo rank is likely more sensitive to the GPU's performance than the CPU's slight variations.

Settings Recommendations

Examining the measured FPS rows, the most stable experience is achieved at the Medium preset across all tested resolutions. At 1920x1080, the Medium preset delivers an average of 111 FPS with a minimum of 94 and a maximum of 127, providing a wide margin above the 60 FPS threshold that is typically considered smooth for a flight simulator. Moving to 2560x1440, the Medium preset still holds strong at 89 FPS average, with minimums of 76 and maximums of 103, ensuring that even in dense urban areas or complex weather systems, the frame rate does not dip into the range of noticeable stutter.

At 3840x2160, the Medium preset is the only one that provides a consistent playable experience, averaging 66 FPS with a minimum of 56 and a maximum of 76. The High preset at 4K drops to an average of 49 FPS, and the Ultra preset falls to 47 FPS, both of which are below the ideal smoothness threshold for a game where precise control is necessary. The data suggests that the Medium preset is the optimal choice for this combo, as it offers the best balance between visual fidelity and frame rate consistency. The Low preset, while providing higher frame rates (142 FPS at 1080p), sacrifices too much visual detail for a game that is as much about the scenery as it is about the flying.

Resolution Scaling

The performance scaling from 1080p to 4K clearly indicates where the bottleneck lies for this configuration. At the Medium preset, the average FPS drops from 111 at 1920x1080 to 89 at 2560x1440, a 19.8% reduction, and then further to 66 at 3840x2160, a 40.5% reduction from the 1080p baseline. This scaling pattern is characteristic of a system that is becoming increasingly GPU-limited as the resolution increases, with the rendering workload growing exponentially.

However, the Low preset shows a different trend. At 1920x1080, the Low preset achieves 142 FPS, which drops to 115 at 2560x1440 and 85 at 3840x2160. The absolute frame rates at low settings are much higher, but the percentage drop from 1080p to 4K is 40.1%, which is very similar to the Medium preset's drop. This suggests that even at Low settings, the GPU is the primary limiter at 4K, as the CPU has enough headroom to feed the graphics card at lower resolutions but the sheer pixel count overwhelms the RTX 3070 Ti's 8 GB of memory and 608.3 GB/s bandwidth.

The data for the High and Ultra presets reinforces this conclusion. At 1080p, the High preset averages 83 FPS, while at 4K it drops to 49 FPS, a 41% reduction. The Ultra preset goes from 79 FPS at 1080p to 47 FPS at 4K, a 40.5% reduction. The consistency of these percentage drops across all presets, hovering around 40%, is a strong indicator that the GPU is the limiting factor at 4K, regardless of the graphical load. The CPU's role is more pronounced at lower resolutions, where the higher frame rates begin to approach the limits of what the i5-11400F can process in terms of simulation logic.

Measured FPS Breakdown

At 1920x1080, the full range of settings is playable, with the Low preset delivering an average of 142 FPS, which is ideal for high refresh rate monitors. The Medium preset provides a balanced 111 FPS average with a minimum of 94 FPS, ensuring no significant dips during complex flight maneuvers. The High preset averages 83 FPS, which is still smooth, while the Ultra preset drops to 79 FPS, showing that the system can handle maximum settings at this resolution with only a minor performance penalty.

Moving to 2560x1440, the performance gap between presets widens. The Low preset still achieves a high 115 FPS average, but the Medium preset drops to 89 FPS with a minimum of 76 FPS. The High preset averages 67 FPS, which is just above the 60 FPS threshold, while the Ultra preset falls to 64 FPS. This resolution is the sweet spot for the combo, as it offers a significant visual upgrade over 1080p while still allowing for high frame rates at Medium settings.

At 3840x2160, the limitations of the RTX 3070 Ti become apparent. The Low preset is the only one that maintains a high average frame rate at 85 FPS. The Medium preset averages 66 FPS with a minimum of 56 FPS, which is borderline acceptable but may experience occasional stutters. The High and Ultra presets both fall below the 50 FPS mark, averaging 49 and 47 FPS respectively, which is not ideal for a simulator that requires precise control. The 8 GB of VRAM is likely a contributing factor at this resolution, as the high-resolution textures can exceed the memory capacity, leading to potential texture streaming issues.

GPU Role

The NVIDIA GeForce RTX 3070 Ti, based on the GA104 chip with 17,400 million transistors, features 8 GB of GDDR6X memory on a 256-bit bus, providing a bandwidth of 608.3 GB/s. The GPU's boost clock of 1770 MHz and base clock of 1575 MHz allow it to achieve a texture rate of 339.8 GTexel/s and a pixel rate of 169.9 GPixel/s. These specifications place the GPU in the 75th percentile of all GPUs, with an average benchmark score of 29945, putting it in a close rivalry with the NVIDIA GeForce RTX 5070 Mobile (29928, 0.1% delta) and the AMD Radeon RX 6800 (30095, -0.5% delta).

In Microsoft Flight Simulator, the GPU's role is primarily in rendering the photogrammetry, terrain textures, and dynamic lighting. The data shows that the GPU is the limiting factor at 4K resolution, as evidenced by the consistent ~40% FPS drop from 1080p across all settings. The 8 GB of VRAM is sufficient for 1080p and 1440p gaming, but at 4K with High or Ultra settings, the memory capacity may be strained. The GPU's FP32 performance of 21.75 TFLOPS is substantial, but the sheer complexity of the rendering workload in a flight simulator, with its vast draw distances and detailed cloud systems, means that the GPU is often the bottleneck at higher resolutions. The benchmark results show that the GPU's DirectX 12 score is 91, which, while not directly comparable to the in-game FPS, indicates that the architecture is well-suited for modern APIs.
