Resolution Scaling

The measured FPS data for Microsoft Flight Simulator with the Intel Core i5-12600KF and AMD Radeon RX 6650 XT reveals a clear pattern of GPU-bound scaling as resolution increases. At 1920x1080 with Low settings, the combo produces 106.7 FPS, which drops to 83.5 FPS at 2560x1440 and further to 58.5 FPS at 3840x2160. That represents a 45.2% reduction from 1080p to 4K at Low settings, indicating the GPU is the primary constraint as pixel count rises.

The scaling behavior shifts dramatically when moving to higher presets. At Ultra settings, the frame rate goes from 57.6 FPS at 1080p to 49 FPS at 1440p, then falls to 33.1 FPS at 4K. The 42.5% drop from 1080p to 4K at Ultra is slightly less severe than at Low, which suggests that at higher settings the workload becomes more balanced between CPU and GPU, though the graphics card still carries most of the burden.

Medium settings tell a similar story: 80.2 FPS at 1080p, 66.9 FPS at 1440p, and 47.4 FPS at 4K. The gap between 1080p and 4K at Medium is 40.9%, while High settings show a 37.4% reduction from 59.6 FPS to 37.3 FPS. This trend indicates that as the preset becomes more demanding, the percentage drop from resolution scaling narrows slightly, pointing to a growing CPU contribution at higher settings.

The data strongly suggests that the RX 6650 XT, with its 8 GB of GDDR6 memory and 128-bit bus delivering 280.3 GB/s bandwidth, is the limiting component at 4K across all presets. At 1080p Low, the 106.7 FPS result shows the i5-12600KF's 10 cores and 16 threads with a 4.90 GHz boost clock are sufficient to keep the GPU well-fed, but the steady decline at each higher resolution confirms the graphics card's bandwidth and compute capacity are the bottlenecks. Players targeting 4K will need to accept sub-60 FPS performance even at Low settings, while 1440p offers a more viable middle ground.

How This Combo Ranks

The combination of the Intel Core i5-12600KF and AMD Radeon RX 6650 XT ranks 1153 out of 1795 tested combos in Microsoft Flight Simulator, placing it in the 35.8th percentile of all configurations. This modest ranking reflects the pairing of a mid-range CPU with an upper-mid-range GPU that is end-of-life in production status, though the measured data shows the combo is entirely playable at several settings.

The i5-12600KF itself sits in the 84th percentile among all CPUs, with an average benchmark score of 27827. Its nearest rivals include the Intel Core i9-10900K at 27829 (0% delta), the Intel Core i5-12600K at 27851 (-0.1%), the Intel Core Ultra 5 125H at 27872 (-0.2%), and the Intel Core i7-13700H at 27716 (0.4%). The performance difference between the i5-12600KF and these rivals is negligible, meaning the CPU is not the primary factor holding back the combo's ranking.

On the GPU side, the Radeon RX 6650 XT achieves a 72nd percentile ranking among all GPUs with an average benchmark score of 29024. Its nearest rivals are the AMD Radeon RX 6800M at 29011 (0% delta), the AMD Radeon RX 470 at 28996 (0.1%), the Intel Arc A370M at 29175 (-0.5%), and the AMD Radeon RX Vega M GH at 29197 (-0.6%). Again, the score differences are minimal, suggesting the GPU's performance class is well-established.

Given that both components perform essentially on par with their direct rivals, the combo's 1153rd rank out of 1795 reflects the overall competitive landscape rather than any specific weakness. The data indicates that many other CPU-GPU pairings outperform this configuration in Flight Simulator, but the combination is far from the bottom of the pile. The ranking implies that users seeking higher placement would need to upgrade either the GPU to a higher-tier Radeon RX 6000 series part or the CPU to a more recent generation, though the measured FPS results show the combo still delivers playable frame rates in several scenarios.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend heavily on the target resolution and desired frame rate. At 1920x1080, the Low preset delivers 106.7 FPS, which is well above the 60 FPS threshold for smooth flight simulation. Medium at 1080p produces 80.2 FPS, still comfortably playable, while High yields 59.6 FPS, just shy of 60. Ultra at 1080p drops to 57.6 FPS, which is acceptable for a flight sim but shows the GPU starting to struggle.

At 2560x1440, the Low preset achieves 83.5 FPS, making it the only settings level at this resolution that clears 60 FPS comfortably. Medium at 1440p produces 66.9 FPS, which is playable for most users, while High and Ultra fall to 48.4 FPS and 49 FPS respectively. The similarity between High and Ultra at 1440p — a difference of only 0.6 FPS — suggests that the Ultra preset offers little benefit over High for the performance cost.

For 3840x2160, no preset reaches 60 FPS. Low produces 58.5 FPS, which is the best result at 4K and nearly playable. Medium delivers 47.4 FPS, High 37.3 FPS, and Ultra 33.1 FPS. The data indicates that 4K gaming on this combo requires accepting either Low settings for near-60 FPS or Medium for a better visual experience at a lower frame rate.

The best experience per the measured rows is Medium at 1080p, offering 80.2 FPS with improved visuals over Low. For users prioritizing frame rate, Low at 1080p at 106.7 FPS is the clear choice. At 1440p, Medium at 66.9 FPS represents the sweet spot between visual fidelity and smoothness, while 4K users should stick with Low at 58.5 FPS or drop to Medium if they can tolerate 47.4 FPS.

Measured FPS Breakdown

At 1920x1080, the full range of settings shows a wide performance spread. Low settings produce 106.7 FPS average, Medium delivers 80.2 FPS, High achieves 59.6 FPS, and Ultra bottoms out at 57.6 FPS. The gap between Low and Medium is 26.5 FPS, while the gap between Medium and High is 20.6 FPS. Interestingly, the difference between High and Ultra is only 2 FPS, suggesting diminishing returns from the highest preset.

Moving to 2560x1440, the measured averages are 83.5 FPS at Low, 66.9 FPS at Medium, 48.4 FPS at High, and 49 FPS at Ultra. The High and Ultra results are nearly identical, with Ultra actually edging out High by 0.6 FPS, which could be within measurement variance but still indicates that the Ultra preset does not consistently outperform High at this resolution.

At 3840x2160, the results compress significantly. Low produces 58.5 FPS, Medium delivers 47.4 FPS, High achieves 37.3 FPS, and Ultra yields 33.1 FPS. The spread from Low to Ultra is 25.4 FPS, which is smaller than the 49.1 FPS spread at 1080p. This compression at 4K reinforces that the GPU is the limiting factor, as the settings-based performance differences shrink when the pixel workload dominates.

Across all resolutions, the pattern is consistent: Low is always the fastest preset, followed by Medium, then High and Ultra in a tight grouping. The only exception is at 1440p where Ultra slightly beats High, but the difference is negligible. The data shows that users can expect roughly a 45-50% performance uplift from Ultra to Low at 1080p, while at 4K that uplift narrows to about 43%.
