Microsoft Flight Simulator

Microsoft Flight Simulator presents an unusually demanding workload that stresses both the CPU and GPU in distinct ways. The measured data for the Intel Core i7-14700KF paired with the NVIDIA GeForce RTX 3080 Ti reveals a configuration that is powerful but must be carefully tuned to hit the smooth frame rates the simulator needs. This analysis walks through the resolution scaling, component roles, and settings recommendations based strictly on the measured FPS data provided.

Resolution Scaling

The frame rate progression from 1080p to 4K shows a clear and consistent pattern of decline, which is typical for a flight simulator that renders vast, detailed scenery. At 1920x1080 with Low settings, the combo achieves an average of 164 FPS. Moving to 2560x1440 at the same preset drops that average to 132 FPS, a reduction of 32 frames. At 3840x2160, the Low preset average falls further to 97 FPS. This scaling indicates that even at the lowest graphical load, the system is capable of delivering very high frame rates at 1080p, but the pixel count increase at 4K still exacts a heavy toll.

The trend is consistent across all settings presets. For Medium settings, the average FPS goes from 127 at 1080p, to 103 at 1440p, and finally to 76 at 4K. The High preset shows averages of 96, 77, and 57 FPS across the same resolution steps. The Ultra preset demonstrates the most dramatic drop, starting at 91 FPS at 1080p, falling to 74 FPS at 1440p, and reaching just 54 FPS at 4K.

The data suggests that the limiting component shifts depending on the resolution. At 1080p, the high frame rates across all settings—even Ultra at 91 FPS—suggest that the CPU is doing the bulk of the work, keeping the GPU fed with enough draw calls to render the complex world. The GPU is not yet the bottleneck. However, the steep decline from 1080p to 4K, particularly the near-halving of frame rates on the Low preset (164 to 97 FPS), indicates that the GPU becomes the primary constraint at higher resolutions. The raw pixel fill rate and memory bandwidth of the RTX 3080 Ti are being taxed heavily as the resolution increases, and the CPU's headroom at 4K is no longer the limiting factor.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is a high-end Ampere architecture GPU with 12 GB of GDDR6X memory on a 384-bit bus, yielding a bandwidth of 912.4 GB/s. Its boost clock is listed at 1665 MHz, and it has a TDP of 350 W. In the context of Microsoft Flight Simulator, this memory configuration is critical. The simulator streams vast amounts of terrain and texture data, and the measured results show that the 12 GB frame buffer is adequate for the tested settings, but the performance scaling suggests that the GPU's compute capabilities are the deciding factor.

The GPU's average benchmark score is 41187, placing it in the 83rd percentile of all GPUs. Its nearest rival, the NVIDIA GeForce RTX 5070, has an average score of 40377, which is 2% lower. The other nearest rivals are older workstation cards, such as the NVIDIA Tesla M40, which score slightly higher but are not comparable in gaming features. The RTX 3080 Ti's raw compute power, rated at 34.10 TFLOPS for FP32, is what allows it to maintain playable frame rates at 1440p Ultra, where it averages 74 FPS. The transition from 1440p to 4K at Ultra, dropping from 74 to 54 FPS, highlights the GPU's struggle with the sheer pixel count, not a lack of VRAM.

The data indicates that the GPU is the dominant bottleneck at 4K, but the CPU still matters. For instance, at 1080p Ultra, the combo hits 91 FPS, which is a very playable result. The fact that the GPU can still produce 54 FPS at 4K Ultra shows that it is a capable card for this title, but the user must accept lower settings to maintain a consistent 60 FPS at that resolution. The VRAM size is not shown to be a problem in these tests, as performance scales predictably with resolution rather than hitting a cliff that would indicate memory exhaustion.

Settings Recommendations

Based on the measured rows, the optimal balance between visual quality and frame rate depends heavily on the target resolution. For a 60 FPS target, the data provides clear guidance.

At 1920x1080, the Ultra preset delivers an average of 91 FPS, which is well above the 60 FPS target. This makes Ultra the recommended setting for 1080p, as it provides the highest visual fidelity without sacrificing smoothness. Even the High preset at 96 FPS is viable, but Ultra offers a better experience for the same frame rate headroom.

For 2560x1440, the Ultra preset averages 74 FPS, which is still comfortably above 60 FPS. The High preset at 77 FPS is also a strong option. However, to maximize visual quality while ensuring a stable frame rate, Ultra is the recommended choice at this resolution, as the average of 74 FPS leaves enough headroom for dips in dense areas.

At 3840x2160, the situation changes. The Ultra preset averages 54 FPS, which is below the 60 FPS target. The High preset averages 57 FPS, also just under the target. The Medium preset, however, averages 76 FPS, which is well above the 60 FPS threshold. This makes Medium the recommended preset for 4K, as it is the highest quality setting that consistently delivers a smooth experience. The Low preset at 97 FPS is an option for users who prioritize frame rate over visuals, but Medium provides a much better visual experience with only a modest frame rate cost.

Measured FPS Breakdown

The following is a detailed enumeration of the exact measured average FPS for each resolution and settings combination.

At 1920x1080, the Low preset produces an average of 164 FPS. The Medium preset averages 127 FPS, with a minimum of 108 FPS and a maximum of 146 FPS. The High preset averages 96 FPS. The Ultra preset averages 91 FPS.

At 2560x1440, the Low preset averages 132 FPS. The Medium preset averages 103 FPS, with a minimum of 87 FPS and a maximum of 118 FPS. The High preset averages 77 FPS. The Ultra preset averages 74 FPS.

At 3840x2160, the Low preset averages 97 FPS. The Medium preset averages 76 FPS, with a minimum of 64 FPS and a maximum of 87 FPS. The High preset averages 57 FPS. The Ultra preset averages 54 FPS.

The data shows a consistent pattern: each step up in resolution reduces the average FPS by a significant margin, and each step up in settings also reduces the average. The Medium preset is the only one with min/max data, showing a variance of about 23 FPS at each resolution, which is a typical spread for a simulator with dynamic scenes.

Its nearest rivals are the AMD Ryzen 7 9700F, which scores 69996 (0.2% lower), and the AMD Ryzen 9 7940HX, which scores 69875 (0.4% lower). The Intel Core Ultra 7 265K scores 70879, which is 1% higher. This shows that the CPU is a top-tier performer, but the 895th rank in this specific game suggests that the GPU is holding the combo back from a higher placement.

The GPU's average score is 41187, which is in the 83rd percentile. Its nearest rival is the AMD Radeon Pro 5300, which scores 40870 (0.8% higher), and the NVIDIA GeForce RTX 5070, which scores 40377 (2% lower). The GPU's performance is solid, but the 895th rank out of 3714 combos indicates that many other configurations, likely with newer or higher-end GPUs, achieve better results in this simulator. The rank suggests that the CPU is not the limiting factor, as its percentile is much higher than the GPU's.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor from the Raptor Lake Refresh generation, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. It has 33 MB of shared L3 cache and supports DDR4 and DDR5 memory. Its benchmark scores are impressive, including a Cinebench R23 multi-core score of 44167 and a single-core score of 6235. The Geekbench multi-core score is 21462, and the single-core score is 2578.

In Microsoft Flight Simulator, the CPU's role is to handle the complex simulation logic, including aircraft systems, weather, and the physics of flight, as well as to manage the streaming of scenery data. The high single-core performance, evidenced by the 6235 Cinebench R23 score, is critical for maintaining high frame rates at lower resolutions. The data supports this: at 1080p, the combo achieves 164 FPS on Low settings, suggesting the CPU is capable of feeding the GPU at a very high rate.

The CPU's multi-core performance, with a PassMark multithread score of 52425, also helps in scenarios with heavy AI traffic or complex scenery. However, the measured FPS data shows that the CPU is not the primary bottleneck at higher resolutions. The frame rate drops from 1080p to 4K are substantial, indicating that the GPU is the limiting factor. At 4K Ultra, the combo only manages 54 FPS, which is a clear sign that the RTX 3080 Ti cannot keep up with the CPU's output. The CPU's 94th percentile ranking versus the GPU's 83rd percentile further confirms that the processor has more headroom than the graphics card in this specific game.
