Microsoft Flight Simulator

The Intel Core i5-12600KF paired with the NVIDIA GeForce RTX 3080 delivers a strong showing in Microsoft Flight Simulator, with measured data indicating that the combination is capable of smooth frame rates across most presets, though 4K Ultra remains out of reach. At 1080p and 1440p, the system clears the 60 FPS threshold even at the most demanding settings, while 4K requires a reduction to Medium settings to maintain playability. The benchmark results place this combo in the 1036th position out of 3714 tested combinations, putting it in the upper third of all systems evaluated for this title.

Measured FPS Breakdown

The measured performance data for this combo shows a clear scaling pattern across resolutions and settings. At 1920x1080, the system produces an average of 158 FPS on Low settings, which drops to 123 FPS on Medium with a minimum of 104 FPS and a maximum of 141 FPS. High settings at 1080p yield 92 FPS average, while Ultra settings still deliver a comfortable 88 FPS average. These numbers indicate that at 1080p, the system has substantial headroom above the 60 FPS playability threshold, with even the most demanding preset maintaining nearly 30 FPS of margin.

Moving to 2560x1440, the performance remains robust but shows the expected impact of increased pixel count. Low settings deliver 127 FPS average, Medium settings produce 99 FPS with a minimum of 84 FPS and a maximum of 114 FPS, and High settings achieve 74 FPS. Ultra at 1440p still manages 71 FPS average, which keeps it above the 60 FPS threshold. The gap between Low and Ultra at this resolution is 56 FPS, demonstrating that the visual preset selection has a significant influence on performance, but even the heaviest load remains playable.

At 3840x2160, the system begins to show its limits. Low settings produce 94 FPS average, which is still well above the threshold. Medium settings deliver 73 FPS with a minimum of 62 FPS and a maximum of 84 FPS, keeping the experience playable but with less margin. High settings drop to 55 FPS average, falling below the 60 FPS target. Ultra settings at 4K produce 52 FPS average, which represents the lowest measured performance in the entire dataset. The drop from Low to Ultra at 4K is 42 FPS, indicating that the resolution is the dominant factor in performance scaling, with the GPU becoming the limiting component.

CPU and GPU Roles

The data reveals a shifting balance between CPU and GPU influence depending on resolution. At 1920x1080, the system achieves 158 FPS on Low settings, which suggests that the Intel Core i5-12600KF with its 10 cores and 16 threads is providing sufficient processing power to keep the GPU well-fed. The 3DMark scores for the CPU, including a multi-threaded score of 7956 and a single-thread score of 1016, indicate strong compute capability that supports high frame rates at lower resolutions where the GPU has less work per frame.

As resolution increases to 2560x1440, the performance drops by approximately 20-25% across most settings compared to 1080p, which points to the GPU taking on a larger role. The RTX 3080 with 8704 shading units and a 320-bit memory bus delivering 760.3 GB/s of bandwidth shows its capacity to handle the increased pixel workload, but the frame rate reductions demonstrate that the GPU is becoming more of a bottleneck. The gap between Low and Ultra at 1440p is 56 FPS, compared to 70 FPS at 1080p, indicating that the GPU's rendering overhead is compressing the range of achievable performance.

At 3840x2160, the GPU becomes the clear limiting factor. The RTX 3080's 10 GB of GDDR6X memory and 29.77 TFLOPS of FP32 compute are pushed hard, and the performance drops to 52 FPS at Ultra. The CPU's role diminishes at this resolution, as the frame rates are constrained by the GPU's ability to fill the 8.3 million pixels per frame. The scaling from 1440p to 4K shows a reduction of roughly 25-30% across settings, which aligns with the pixel count increase of approximately 2.25x, suggesting that the GPU is the dominant factor at 4K.

Best Settings per Resolution

For 3840x2160, the most demanding preset that remains at or above 60 FPS is Medium, which delivers an average of 73 FPS with a minimum of 62 FPS. This provides a playable experience with some margin above the threshold, though the minimum frame rate of 62 FPS indicates that there is limited headroom during demanding scenes. High settings at 4K fall short at 55 FPS, so Medium is the recommended choice for this resolution.

At 2560x1440, all four presets achieve at least 60 FPS, but the best setting is Ultra, which delivers 71 FPS average. This is a strong result, as it allows users to experience the full visual fidelity of the game without sacrificing smoothness. The 71 FPS average provides a comfortable margin above the threshold, and even the most complex scenes should remain fluid.

For 1920x1080, Ultra settings are the best choice, producing 88 FPS average. This is the highest preset available and delivers a smooth experience with significant headroom. The 88 FPS average means the system can handle the most demanding visual settings at 1080p without any concerns about dropping below the playability threshold.

Similar Performance Alternatives

Looking at the CPU's nearest rivals, the Intel Core i9-10900K posts an average score of 27872, which is 0.3% lower than the i5-12600KF's average of 27799. The AMD Ryzen 7 5800X3D scores 27896, also 0.3% higher, and the AMD Ryzen 7 6800U scores 27887, 0.3% higher. The AMD Ryzen 5 8500GE scores 27712, which is 0.3% lower. These deltas are minimal, meaning that swapping the i5-12600KF for any of these alternatives would result in nearly identical CPU-bound performance in Microsoft Flight Simulator.

On the GPU side, the RTX 3080's average benchmark score is 23172, with its nearest rivals showing very small differences. The NVIDIA P106-100 scores 23249, 0.3% higher, while the AMD Radeon Pro Vega 16 scores 23250, 0.3% higher. The AMD Radeon RX 6600M scores 23273, 0.4% higher, and the AMD Radeon R9 M290X scores 23276, 0.4% higher. These rival GPUs would produce essentially the same frame rates as the RTX 3080 in this game, though it is important to note that the measured FPS data applies specifically to the RTX 3080 configuration.

The Verdict

This PC can run Microsoft Flight Simulator with playable frame rates at all three tested resolutions, provided the settings are chosen appropriately. At 1920x1080, all four presets clear the 60 FPS threshold, with Ultra delivering 88 FPS. At 2560x1440, all presets also remain above 60 FPS, with Ultra at 71 FPS. For 3840x2160, the system achieves playable performance on Low at 94 FPS and Medium at 73 FPS, but High at 55 FPS and Ultra at 52 FPS fall short of the 60 FPS target. The data indicates that the sweet spot for this combo is 1440p Ultra or 1080p Ultra, where users get the full visual experience with solid performance. At 4K, users should stick to Medium settings to maintain a consistent experience above the threshold.

How This Combo Ranks

The combo ranks 1036th out of 3714 tested combinations in Microsoft Flight Simulator, placing it in the 72nd percentile of all systems evaluated. This is a respectable position, considering the game's demanding nature and the large number of tested configurations. The rank reflects the balance between the CPU's 79th percentile ranking among all processors and the GPU's 68th percentile ranking among all graphics cards. The combination of a strong mid-range CPU with a high-end GPU from the previous generation results in performance that is better than the GPU's percentile alone would suggest, indicating that the CPU provides adequate support for the RTX 3080 in this title. The system sits comfortably in the upper third of all tested combos, making it a viable choice for users seeking high frame rates at 1440p or playable performance at 4K with adjusted settings.
