Microsoft Flight Simulator

Microsoft Flight Simulator is a notoriously demanding title, and the data for this combination of an Intel Core i7-14700K and NVIDIA GeForce RTX 4080 shows a system that is clearly capable of handling it, but with distinct performance characteristics depending on resolution and settings. The measured FPS across the board indicates a strong pairing, yet the scaling between presets and resolutions reveals where the bottlenecks lie. This analysis breaks down the raw numbers to show what you can expect from this specific hardware configuration.

Resolution Scaling

The transition from 1080p to 4K with this setup shows a classic pattern of GPU-bound scaling, though the CPU remains a significant factor even at lower resolutions. At 1080p with Low settings, the system produces an average of 211 FPS. Moving to 1440p drops that to 170 FPS, a 41 FPS reduction, and at 4K it falls to 125 FPS. This steep decline from 1080p to 4K highlights how the rendering load increases exponentially with pixel count. The gap from 1440p to 4K is 45 FPS, which is slightly larger than the 41 FPS drop from 1080p to 1440p, indicating that the GPU is working progressively harder as resolution climbs.

With the High preset, the scaling is more linear. The average FPS at 1080p is 123, at 1440p it is 99, and at 4K it drops to 73. The deltas here are 24 FPS and 26 FPS respectively, showing a consistent performance hit per resolution step. This suggests that at High settings, the workload is more evenly balanced, but the GPU is still the primary limiter. The Ultra preset shows the most severe drop at the highest resolution: 117 FPS at 1080p, 95 FPS at 1440p, and only 70 FPS at 4K. The 25 FPS difference between 1440p and 4K at Ultra is the largest single-step drop in the entire dataset, confirming that the RTX 4080's limits are reached when pushing maximum fidelity at 4K.

The most telling data point for identifying the limiting component comes from the Low preset. At 1080p Low, the system hits 211 FPS, which is extremely high. The fact that it drops to 170 FPS at 1440p and 125 FPS at 4K on Low settings shows that even with minimal graphical load, the GPU is still being pushed harder by higher resolutions. However, the 1080p Low result of 211 FPS is where the CPU starts to show its ceiling; the i7-14700K is likely preventing an even higher frame rate at this low-fidelity setting. The data indicates that at 1080p Low, the CPU is the limiting factor, while at 4K Ultra, the GPU is definitively the bottleneck.

GPU Role

The NVIDIA GeForce RTX 4080 is the driving force behind the high frame rates in this data, particularly at higher resolutions. Its 16 GB of GDDR6X memory on a 256-bit bus provides a bandwidth of 716.8 GB/s, which is ample for the high-resolution textures used in Microsoft Flight Simulator. The GPU's boost clock of 2505 MHz and base clock of 2205 MHz are the key clocks that determine its processing speed. The data shows that the GPU's performance is not the bottleneck until the resolution and settings are pushed to the extreme.

The GPU's synthetic benchmarks reinforce its position. With a percentile rank of 86, it sits above the majority of other GPUs in the database. Its Passmark G3D score of 34457 and Geekbench Vulkan score of 263779 are strong indicators of its raw compute power. The 3DMark Steel Nomad DX12 score of 6567 shows its DirectX 12 performance is robust. The RTX 4080's nearest rival, the RTX 4080 SUPER, is only 0.1% faster, meaning the performance gap between these two cards is negligible in practice.

In this specific game, the GPU's role becomes clear when examining the measured FPS. At 4K Ultra, the average FPS of 70 is the lowest in the dataset, indicating that the GPU is fully saturated. Conversely, at 1080p Low, the GPU is not the limiting factor, as evidenced by the 211 FPS average. The GPU's 16 GB of VRAM is not likely to be a limiting factor at these settings, given the game's data. The RTX 4080 is a high-end card that provides excellent performance, but the data shows it has a clear ceiling at 4K with the highest quality presets.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at how the system performs across all resolution and settings combinations. At 1920x1080, the Low preset yields an average of 211 FPS. The Medium preset at this resolution averages 164 FPS, with a minimum of 139 FPS and a maximum of 188 FPS. The High preset averages 123 FPS, and the Ultra preset averages 117 FPS. The scaling from Low to Ultra at 1080p shows a 94 FPS difference, which is substantial.

At 2560x1440, the Low preset averages 170 FPS. The Medium preset averages 132 FPS, with a minimum of 112 FPS and a maximum of 152 FPS. The High preset averages 99 FPS, and the Ultra preset averages 95 FPS. The drop from Low to Ultra at 1440p is 75 FPS. At 3840x2160, the Low preset averages 125 FPS. The Medium preset averages 97 FPS, with a minimum of 83 FPS and a maximum of 112 FPS. The High preset averages 73 FPS, and the Ultra preset averages 70 FPS. The drop from Low to Ultra at 4K is 55 FPS.

The data shows that the Medium preset is the only one with recorded minimum and maximum FPS values across all resolutions. At 1080p Medium, the range is 139 to 188 FPS. At 1440p Medium, the range is 112 to 152 FPS. At 4K Medium, the range is 83 to 112 FPS. This suggests that the Medium preset provides a stable experience, with the variance being roughly consistent across resolutions. The High and Ultra presets do not have min/max data, but their averages are consistently lower. The Low preset also lacks min/max data, but its high averages indicate it is the least demanding.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this hardware depend heavily on the target resolution and desired frame rate. For players using a 1080p monitor, the Ultra preset is viable, as it provides an average of 117 FPS, which is well above the 60 FPS threshold for smooth gameplay. The High preset offers a slight performance boost at 123 FPS, but the visual difference may not justify the change. The Medium preset at 164 FPS is an excellent choice for those with high refresh rate monitors, as it provides a very smooth experience.

At 1440p, the Ultra preset provides an average of 95 FPS, which is still playable on most displays. The High preset at 99 FPS is nearly identical in performance, making the choice between the two a matter of visual preference. The Medium preset at 132 FPS is the best option for competitive or fast-paced play, as it offers a significant frame rate advantage over the higher presets. The data suggests that High or Ultra at 1440p is the sweet spot for balancing visual quality and performance.

At 4K, the situation changes. The Ultra preset averages 70 FPS, which is playable but may not be ideal for all users, especially those sensitive to frame rate drops. The High preset at 73 FPS is almost the same, indicating that the GPU is the limiting factor. The Medium preset at 97 FPS is the recommended choice for 4K, as it provides a substantial frame rate increase over High and Ultra while still offering a good visual experience. The Low preset at 125 FPS is the best for maximum performance, but it sacrifices significant visual fidelity. For the best overall experience at 4K, the Medium preset is the clear winner, as it is the only 4K setting that comfortably exceeds 90 FPS.

CPU Role

The Intel Core i7-14700K plays a crucial role in this system, particularly at lower resolutions and settings where the GPU is not fully utilized. With 20 cores and 28 threads, this CPU has substantial multi-threaded capacity. Its boost clock of 5.60 GHz and base clock of 3.40 GHz are high figures that contribute to its strong single-threaded performance. The 33 MB of shared L3 cache is also beneficial for game logic and asset streaming.

The CPU's synthetic benchmark results are impressive. Its Cinebench R23 multi-core score of 33440.5 and single-core score of 2160 reflect its ability to handle both heavily threaded and lightly threaded workloads. The Geekbench multi-core score of 20767 and single-core score of 2569 further confirm its strength. The Passmark single-thread score of 4472 is particularly relevant for Microsoft Flight Simulator, which often relies on a single main thread for simulation logic. The CPU's percentile rank of 94 places it in the top 6% of all CPUs, and its average benchmark score of 69355 is nearly identical to the AMD Ryzen 9 7950X, which scores 69515.

In the context of this game, the CPU's role is most evident in the 1080p Low preset, where the average FPS is 211. This high frame rate indicates that the CPU is able to feed the GPU efficiently, but the fact that it isn't higher suggests a CPU bottleneck at this setting. At higher resolutions and settings, the GPU takes over as the primary limiter, but the CPU's strong single-threaded performance ensures that it doesn't hold back the system. The data suggests that the i7-14700K is more than capable of supporting the RTX 4080 in this title, and its 20-core configuration provides ample headroom for other tasks running in the background.
