Microsoft Flight Simulator

Microsoft Flight Simulator is notoriously demanding, and the combination of the Intel Core i5-14600KF and the Intel Arc B390 lands in a very specific performance tier. The data shows this pairing is firmly anchored at the low end of the GPU spectrum, which means the experience is heavily dictated by graphics settings and resolution rather than the CPU’s capabilities. The benchmark results reveal a system that can achieve playable frame rates only by making significant compromises, and even then, the margins are thin.

Resolution Scaling

The measured FPS data shows a clear and steep penalty as resolution increases, which is the classic signature of a GPU-bound scenario. At 1920x1080 with Low settings, the combo produces an average of 56 FPS. Dropping to 2560x1440 at the same settings yields 45 FPS, and at 3840x2160, the average falls to 33 FPS. This represents a roughly 20% performance drop from 1080p to 1440p, and a further 27% drop from 1440p to 4K. The scaling is consistent, but the absolute numbers are low across the board.

This pattern strongly indicates that the Intel Arc B390 is the limiting component. The frame rate decline from 1080p to 4K is nearly linear, which is typical when the GPU is struggling to fill pixels. The CPU, a 14-core Core i5-14600KF with a 5.30 GHz boost clock, is unlikely to be the bottleneck at these low frame rates. For context, the GPU’s benchmark percentile is in the single digits, ranking at the 9th percentile among all GPUs, while the CPU sits at the 90th percentile among all CPUs. This massive disparity confirms that the graphics card is the primary constraint.

When looking at higher settings, the resolution scaling becomes even more punishing. At High settings, the average FPS drops from 33 at 1080p to 26 at 1440p, and finally to 19 at 4K. The drop from 1440p to 4K is a 27% reduction, showing that the GPU is overwhelmed by the pixel count. The data suggests that 4K is not a viable target for this combo under any settings, as even the Low preset only manages 33 FPS, which is below the threshold for smooth gameplay in a simulator.

The implication is clear: users with this hardware should treat 1080p as the primary resolution. The gap between 1080p and 1440p is significant, and the gap to 4K is prohibitive. The scaling behavior confirms that any attempt to push higher resolutions will result in a disproportionately large loss in performance, solidifying the GPU as the definitive bottleneck.

CPU Role

The Intel Core i5-14600KF is a 14-core, 20-thread processor based on the Raptor Lake architecture. It has a base clock of 3.50 GHz and a boost clock of 5.30 GHz. In synthetic tests, it posts strong numbers, including a Geekbench single-core score of 2445 and a multi-core score of 17085. Its performance in the Cinebench R20 tests shows 1929 points in single-core and 13668 points in multi-core. These scores place the CPU in the 90th percentile of all CPUs, indicating it is a high-end part.

However, in this specific game configuration, the CPU’s role is largely secondary. The benchmark results show that the frame rates are consistently low, regardless of the CPU’s potential. For example, at 4K with High settings, the average FPS is 19. This is a scenario where the GPU is clearly saturated, and the CPU is waiting for the graphics card to finish its work. The CPU’s high single-thread performance, evidenced by its Passmark single-thread score of 4273, is not being fully utilized because the GPU cannot feed frames fast enough.

The data suggests that the CPU is not the limiting factor. The combo’s performance is almost entirely dictated by the Intel Arc B390, which has a 3DMark score of just 1482 and ranks in the 9th percentile among all GPUs. The CPU’s nearest rivals, such as the AMD Ryzen 9 7900, have similar average scores (49228 vs. 49394), but this doesn’t translate to better in-game performance because the GPU is the same. In this pairing, the CPU is like a high-performance engine connected to a very small fuel tank; it has the power, but it cannot deliver it to the wheels.

The CPU’s cache configuration includes 24 MB of shared L3 cache, which is beneficial for game logic and asset streaming. But even with this, the measured FPS at 1080p Ultra is only 31, which is a clear sign that the GPU is the primary constraint. The CPU’s role here is to ensure that the system doesn’t introduce additional stutters or bottlenecks, but it cannot overcome the GPU’s fundamental limits. The benchmark data indicates that upgrading the GPU would yield far more significant gains than upgrading the CPU.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend heavily on the user’s tolerance for frame rate dips. For a smooth experience, the Low preset at 1080p is the only configuration that breaks the 50 FPS barrier, achieving an average of 56 FPS. This is the recommended starting point. The Medium preset at 1080p offers a 43 FPS average, which is playable but may feel less fluid, especially in dense urban areas or during weather changes. The High and Ultra presets at 1080p produce 33 and 31 FPS respectively, which are marginal for a simulator that requires precise control.

If the user insists on higher visual fidelity, the Medium preset at 1440p is the most balanced choice. It yields an average of 35 FPS with a minimum of 30 and a maximum of 40. This provides a consistent experience, though it is far from the 60 FPS ideal. The data suggests avoiding High and Ultra settings at 1440p, as they drop to 26 and 25 FPS respectively, which is likely to feel sluggish. At 4K, the Low preset is the only one that approaches playability at 33 FPS, but this is a compromise that sacrifices nearly all visual quality.

The data shows that the Low preset at 1080p is the sweet spot for this hardware combination. It offers the highest average frame rate and the most headroom for complex scenes. The Medium preset is a viable alternative for users who prioritize visuals over raw smoothness, but the jump from Low to Medium costs 13 FPS at 1080p. Given that the GPU’s performance is so limited, the analysis recommends sticking to Low settings at 1080p for the best overall experience, and using Medium only if the user can tolerate occasional dips below 40 FPS.

How This Combo Ranks

In the grand scheme of tested hardware combinations for Microsoft Flight Simulator, this pairing of the Intel Core i5-14600KF and Intel Arc B390 is positioned near the bottom. The combo ranks 2665 out of 2996 tested combos, placing it in the bottom 11% of all configurations. This rank is consistent with the GPU’s individual performance, which sits at the 9th percentile among all GPUs. The CPU, on the other hand, ranks at the 90th percentile, but this is not enough to lift the combo’s standing in a game that is heavily GPU-bound at these settings.

The rank reflects the reality that the Intel Arc B390 is a very low-end graphics solution. Its 3DMark Steel Nomad score of 1482 is just 1.3% higher than the NVIDIA GeForce GT 520MX, which is a legacy mobile part. This indicates that the GPU is several tiers below what is typically used for modern gaming, even at 1080p. The CPU’s high scores, such as its Cinebench R23 multi-core result of 32544, do not compensate for the GPU’s limitations. The combo rank is a holistic measure, and the weak link is clearly the graphics card.

Users looking at this combo should be aware that it will not provide a competitive experience in Microsoft Flight Simulator. The rank of 2665 out of 2996 suggests that most other hardware pairings will outperform it. However, the data also shows that the CPU is a solid foundation for a future GPU upgrade. If the user were to pair the i5-14600KF with a more capable graphics card, the combo’s rank would improve dramatically, as the CPU has the headroom to support much higher frame rates.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo’s performance across resolutions and settings. At 1920x1080, the Low preset delivers an average of 56 FPS, which is the highest score recorded for this combo. The Medium preset follows at 43 FPS, with a minimum of 37 and a maximum of 50. The High preset drops to 33 FPS, and the Ultra preset falls further to 31 FPS. This shows a clear degradation as settings increase, with a 45% performance loss from Low to Ultra.

At 2560x1440, the performance scales down predictably. The Low preset averages 45 FPS, while the Medium preset averages 35 FPS, with a tight range of 30 to 40 FPS. The High preset averages 26 FPS, and the Ultra preset averages 25 FPS. The gap between Low and Ultra at 1440p is 20 FPS, which is a smaller absolute difference than at 1080p, but the percentage loss is similar. The data shows that 1440p is only feasible on Low or Medium settings.

At 3840x2160, the combo struggles to maintain playable frame rates. The Low preset averages 33 FPS, which is the only configuration above 30 FPS at this resolution. The Medium preset averages 26 FPS, with a minimum of 22 and a maximum of 30. Both the High and Ultra presets average 19 FPS, which is effectively unplayable for a flight simulator. The data confirms that 4K is not a realistic target for this hardware, and users should stick to 1080p for any semblance of smooth performance.
