Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title, and the data for the Intel Core i5-14600KF and NVIDIA GeForce RTX 5090 D combo shows a system built to conquer it. This pairing sits at rank 20 out of 2996 tested combinations, placing it in the top 1% of all configurations in our database. That ranking is not just about raw component strength; it reflects how these two parts work together to handle the game's complex simulation and rendering loads, delivering a high-refresh-rate experience even at the most demanding settings.

How This Combo Ranks

The combo's position at 20 out of 2996 tested pairings is a strong indicator of top-tier performance. It places this system ahead of the overwhelming majority of other CPU and GPU combinations we have measured in this specific title. This rank is a product of the synergy between the processor and graphics card, and the data shows that neither component is a significant bottleneck in typical gameplay. The system is able to maintain high frame rates that only a small fraction of tested systems can achieve, making it a top-tier choice for flight simulation enthusiasts.

When breaking down the individual components, the CPU holds a percentile of 90 against all tested processors, while the GPU has a percentile of 92 against all tested graphics cards. These high individual percentiles suggest that both parts are performing near the top of their respective classes. However, the combined rank is even more impressive, suggesting that the two work together efficiently. The CPU's nearest rivals, such as the AMD Ryzen 9 7900 (0.3% higher average score) and the Intel Core Ultra 5 245 (0.8% higher), are extremely close in synthetic benchmarks. This indicates that the i5-14600KF is providing a level of processing power that is competitive with much more expensive and higher-core-count chips.

Similarly, the GPU's nearest rivals in synthetic benchmarks are the AMD Radeon RX 6850M XT (1.6% lower) and the NVIDIA Tesla P100 PCIe 16 GB (2.4% lower). While these are different classes of hardware, the benchmark deltas are small, showing that the RTX 5090 D is a formidable performer. The real-world game data, however, shows a clear picture: this combo is built for high-performance 1080p and 1440p gaming, and it's also very capable at 4K. The measured frame rates indicate that the system is consistently pushing well above 60 FPS, and in many cases, well above 100 FPS, which confirms its overall ranking.

GPU Role

The NVIDIA GeForce RTX 5090 D is the undisputed workhorse of this pairing, and its specifications are central to the game's high performance. The GPU features 32 GB of GDDR7 memory on a 512-bit bus, providing a massive 1.79 TB/s of bandwidth. In a game like Microsoft Flight Simulator, which streams vast amounts of terrain and scenery data, this memory capacity and bandwidth are critical. It allows the card to hold a large portion of the world in its frame buffer, reducing stutters and pop-in. The high memory bandwidth ensures that the GPU can quickly access this data, keeping the frame pipeline full.

The GPU's core specifications are equally impressive. With a base clock of 2017 MHz and a boost clock of 2407 MHz, the card is running at high frequencies. The 21760 shading units and 680 texture mapping units provide immense compute and texture-processing power. This translates directly to the ability to render the highly detailed aircraft models, complex weather effects, and dense urban environments with high fidelity. The card also has 170 ray tracing cores and 680 tensor cores, though the measured FPS data in our pack does not specify whether ray tracing or DLSS was enabled. Regardless, the raw rasterization power is sufficient to produce the high frame rates we see in the data.

The significance of the GPU is most apparent when looking at the performance scaling with resolution. At 1080p, the GPU is not the primary limiting factor, as the frame rates are exceptionally high. However, as resolution increases to 4K, the GPU's workload grows significantly. The data shows that at 4K with Ultra settings, the average FPS is 84, which is a substantial drop from the 142 FPS at 1080p Ultra. This indicates that the GPU is being pushed much harder at higher resolutions, but it still maintains a very playable frame rate. The RTX 5090 D's massive memory pool and high bandwidth are what allow it to handle this increased load without becoming a severe bottleneck.

CPU Role

The Intel Core i5-14600KF provides the processing foundation for this system. It is a 14-core, 20-thread processor with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. The high boost clock is crucial for Microsoft Flight Simulator, which is known for its heavy reliance on single-threaded performance for the core simulation loop. The 24 MB of shared L3 cache also helps by keeping frequently accessed data close to the cores, reducing latency. The CPU's benchmark scores, such as 4594 in Cinebench R23 single-core and 32544 in multi-core, demonstrate its strong processing capabilities.

In this game, the CPU's role is to simulate the physics, aerodynamics, and the world's logic. The data shows that at 1080p with Low settings, the system reaches an average of 225 FPS. This high frame rate is likely more dependent on the CPU, as the GPU is not being heavily taxed at this low resolution and settings level. The fact that the system can reach such high frame rates suggests that the CPU is keeping up with the simulation's demands, preventing it from becoming a bottleneck even in less GPU-intensive scenarios. The processor's position in the 90th percentile and its close benchmark scores to rivals like the AMD Ryzen 9 7900 (0.3% difference) confirm that it is not a weak link.

However, the CPU's influence on performance changes with resolution. As the resolution increases from 1080p to 4K, the gap between frame rates at Low and Ultra settings widens. For example, at 1080p Low is 225 FPS and Ultra is 142 FPS, a difference of 83 FPS. At 4K Low is 151 FPS and Ultra is 84 FPS, a difference of 67 FPS. While the absolute frame rates drop, the relative performance gap between settings does not fully close. This suggests that while the GPU becomes more of a limiting factor at 4K, the CPU's performance is still a significant contributor to the overall frame rate, especially at lower settings where it is the primary bottleneck. The 14 cores and 20 threads ensure that background tasks and the game's threading model are handled without issue.

Resolution Scaling

The performance scaling from 1080p to 4K provides a clear picture of the system's balance. At 1080p with Low settings, the system achieves 225 FPS. This is an extremely high frame rate that suggests the CPU is the primary limiting factor. The GPU is likely not working at full capacity because the rendering load is low, but the CPU is still processing the simulation. As we move to 1440p Low, the frame rate drops to 205 FPS, and at 4K Low, it drops to 151 FPS. This scaling shows that even at Low settings, the GPU's workload increases significantly with resolution.

The scaling at Ultra settings is more telling. At 1080p Ultra, the system achieves 142 FPS. At 1440p Ultra, it drops to 114 FPS, and at 4K Ultra, it reaches 84 FPS. The drop from 1080p to 4K is 58 FPS, which is a 41% performance decrease. This is a significant drop, but the resulting 84 FPS is still a very playable experience. The data indicates that as resolution increases, the GPU becomes the dominant bottleneck. The fact that the 4K Ultra frame rate is still above 60 FPS shows the immense power of the RTX 5090 D, but the scaling also shows that even this top-tier GPU is challenged by the combination of high resolution and maximum settings.

The data also shows that the performance penalty for moving from 1080p to 1440p is less severe than moving from 1440p to 4K. For example, at High settings, the drop from 1080p (149 FPS) to 1440p (120 FPS) is 29 FPS, while the drop from 1440p to 4K (88 FPS) is 32 FPS. This suggests that the GPU is being pushed into a more demanding performance envelope at 4K, where the sheer number of pixels requires significantly more processing power and memory bandwidth. This analysis of scaling is crucial for understanding which component to upgrade first, and in this case, the GPU is doing the heavy lifting at higher resolutions.

Settings Recommendations

The measured FPS data allows for clear recommendations on settings presets, depending on your resolution and performance goals. For gamers with a 1080p monitor, the Ultra preset is highly recommended. The system maintains an average of 142 FPS at this resolution, which is well above the threshold for high-refresh-rate monitors. The visual improvement from High to Ultra is substantial, and the performance cost is minimal in this context. If you have a 240Hz monitor, even the High preset at 149 FPS or Medium at 198 FPS offers an excellent experience, but Ultra provides the best visual fidelity without sacrificing playability.

At 1440p, the High preset is the sweet spot. It delivers an average of 120 FPS, which is an ideal target for a high-refresh-rate 1440p monitor. The Ultra preset, at 114 FPS, is also a strong option if you prefer maximum visual quality over a few extra frames per second. The Medium preset at 159 FPS is a good choice if you want to maximize frame rates, but you will be sacrificing some visual detail in a game where the scenery is a major part of the experience. We would recommend High as the default, with Ultra for those who want the best image quality.

At 4K, the situation is different. The Ultra preset, while playable at 84 FPS, may not be stable enough on a high-refresh-rate 4K display for some users. The High preset, at 88 FPS, offers a negligible performance improvement over Ultra. The Medium preset, at 118 FPS, provides a much larger performance boost and is the best option for a 120Hz or higher refresh rate 4K monitor. The data shows that the jump from High to Medium at 4K results in a 30 FPS increase, which is significant. For the smoothest 4K experience, Medium is the recommended choice, but High is perfectly acceptable for those who prefer better visuals and have a 60Hz or 120Hz display. The Low preset, at 151 FPS, is not recommended as it severely reduces visual quality for a frame rate that is not necessary.
