Microsoft Flight Simulator

The Intel Core i5-12600KF paired with the NVIDIA GeForce RTX 5080 delivers a commanding performance profile in Microsoft Flight Simulator, with measured data showing every tested resolution and preset combination clearing the 60 FPS playability threshold. This combination of a 12th-generation Alder Lake processor and a Blackwell-architecture GPU produces average frame rates that range from a low of 74.3 FPS at 4K Ultra settings to a high of 205.6 FPS at 1080p Low settings, indicating substantial headroom across the board.

Measured FPS Breakdown

At 3840x2160, the data shows a clear progression from the most demanding to the least demanding preset. Ultra settings produce an average of 74.3 FPS, while High settings yield 75.3 FPS — a marginal difference of just one frame per second. Dropping to Medium increases performance to 101.2 FPS, and Low settings deliver 131 FPS. The gap between Low and Ultra at 4K is 56.7 FPS, representing a 76.3% performance uplift when sacrificing visual fidelity.

Moving to 2560x1440, the frame rates scale upward significantly. Ultra settings average 101.4 FPS, High settings reach 103.6 FPS, Medium settings hit 142.2 FPS, and Low settings produce 176.2 FPS. The difference between Ultra and High at this resolution narrows to just 2.2 FPS, suggesting that High and Ultra place nearly identical loads on the hardware. The spread from Low to Ultra here is 74.8 FPS, a 73.8% increase from the most demanding preset.

At 1920x1080, the combination shows its full potential. Ultra settings average 123.1 FPS, High settings deliver 131.6 FPS, Medium settings reach 175.3 FPS, and Low settings peak at 205.6 FPS. The delta between Low and Ultra at 1080p is 82.5 FPS, which translates to a 67% performance difference. Notably, even at the highest preset, the system maintains an average comfortably above the 60 FPS playability threshold, with 123.1 FPS representing more than double the minimum playable frame rate.

CPU and GPU Roles

The scaling patterns across resolutions reveal how this game distributes workload between the Core i5-12600KF and the RTX 5080. The 10-core, 16-thread processor with a boost clock of 4.90 GHz provides a strong foundation, but the data indicates that the GPU becomes the dominant factor as resolution increases. Between 1080p and 1440p, the average frame rates across all presets drop by approximately 20-25%, while the jump from 1440p to 4K produces a further 25-30% reduction. This consistent scaling suggests the RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth are the primary drivers of performance at higher resolutions.

At 1080p, the CPU's role is more pronounced. The i5-12600KF's single-thread score of 3302 in Cinebench R23 and its 3dmark single-thread score of 1016 indicate strong per-core performance that helps maintain high frame rates when the GPU is not fully saturated. The gap between Low and Ultra at 1080p is 82.5 FPS, compared to 74.8 FPS at 1440p and 56.7 FPS at 4K. This narrowing gap at higher resolutions confirms that the RTX 5080 becomes the bottleneck as pixel count increases, while the CPU has more influence at lower resolutions.

The preset scaling within each resolution also points to GPU-bound behavior. At 4K, the difference between Medium and High is 25.9 FPS, while the difference between High and Ultra is only 1 FPS. This compression at the top end suggests that Ultra settings introduce effects that are particularly demanding on the GPU's 10752 shading units and 112 ROPs, but the RTX 5080's 56.28 TFLOPS of FP32 performance handles them without significant frame rate collapse.

Best Settings per Resolution

At 3840x2160, Ultra settings are the most demanding preset that remains playable, with an average of 74.3 FPS. This clears the 60 FPS threshold by 14.3 FPS, providing a meaningful margin for scene complexity variations. The data shows this is the optimal choice for 4K, as High settings only improve the average by 1 FPS to 75.3 FPS, making the visual upgrade from High to Ultra essentially free in performance terms.

For 2560x1440, Ultra settings again represent the best option, averaging 101.4 FPS. This is 41.4 FPS above the playability threshold, indicating that users have substantial headroom even in the most demanding preset. The gap between Ultra and High at this resolution is a mere 2.2 FPS, so choosing Ultra over High costs almost nothing in frame rate while delivering maximum visual quality.

At 1920x1080, Ultra settings deliver 123.1 FPS on average, which is 63.1 FPS above the 60 FPS minimum. This represents the highest absolute headroom of any resolution tested. The combination of the CPU's strong multi-threaded performance — evidenced by its Cinebench R23 multi-core score of 23391 and Passmark multithread score of 27575 — and the GPU's raw power ensures that even the most demanding preset at the most common gaming resolution remains far above playable thresholds.

How This Combo Ranks

The combination ranks 161st out of 3714 tested configurations for Microsoft Flight Simulator, placing it in the top 4.3% of all combos in the database. This percentile placement is notable given the game's reputation as a demanding simulation title. The CPU's percentile ranking of 79 among all processors, combined with the GPU's percentile ranking of 87 among all graphics cards, creates a synergistic pairing that performs better than either component's individual percentile might suggest.

The rank of 161 out of 3714 indicates that this combo outperforms the vast majority of tested systems, though it falls short of the absolute top tier. The data implies that systems ranked higher than 161st likely feature more powerful CPUs or multi-GPU configurations, but for a single CPU and single GPU setup, this pairing sits near the upper echelon of performance. The measured FPS data supports this ranking, as even the most demanding 4K Ultra preset maintains an average above 74 FPS, a result that many combinations in the database likely cannot achieve.

Similar Performance Alternatives

The CPU's nearest rivals provide context for what other processors would behave similarly in this configuration. The Intel Core i9-10900K scores an average of 27872 in benchmarks, just 0.3% lower than the i5-12600KF's 27799 average. The AMD Ryzen 7 5800X3D scores 27896, also within 0.3% of the i5-12600KF. These three processors are effectively performance equivalents, meaning users with a Core i9-10900K or a Ryzen 7 5800X3D paired with an RTX 5080 would see nearly identical frame rates in Microsoft Flight Simulator.

The AMD Ryzen 5 8500GE scores 27712, which is 0.3% higher than the i5-12600KF, and the AMD Ryzen 7 6800U scores 27887, also 0.3% higher. These four rivals bracket the i5-12600KF's performance within a narrow 0.6% window, confirming that the processor's 79th percentile ranking is well-earned. For the GPU, the RTX 5080's nearest rivals include the AMD Radeon RX 9070 GRE, which scores 57367 on average — 2.2% higher than the RTX 5080's 56083. The AMD Radeon 8060S scores 55757 (0.6% lower), the AMD Radeon RX 6750 GRE 12 GB scores 55698 (0.7% lower), and the AMD Radeon Pro W5700X scores 54828 (2.3% lower).

The Verdict

The Intel Core i5-12600KF and NVIDIA GeForce RTX 5080 combination can absolutely run Microsoft Flight Simulator at playable frame rates across all tested resolutions and settings. The verdict data confirms that every resolution — 1920x1080, 2560x1440, and 3840x2160 — has all four presets (Low, Medium, High, and Ultra) marked as playable, with average frame rates at the most demanding settings of 123.1 FPS, 101.4 FPS, and 74.3 FPS respectively.

The best settings at each resolution are Ultra, with the average FPS at those settings exceeding the 60 FPS threshold by substantial margins. At 4K Ultra, the 74.3 FPS average provides a comfortable buffer above the playability threshold, though it is the closest margin of any configuration tested. At 1440p Ultra, the 101.4 FPS average offers significant headroom for demanding scenes or future content updates. At 1080p Ultra, the 123.1 FPS average ensures a smooth experience even in the most complex flight scenarios.

The data indicates that this system is not merely playable but genuinely capable of delivering high-refresh-rate experiences at lower resolutions and solid 4K performance at maximum settings. The RTX 5080's 16 GB of GDDR7 memory and the i5-12600KF's robust multi-threaded performance combine to create a configuration that handles Microsoft Flight Simulator's demanding rendering requirements without compromise. For users seeking to run this simulation at its highest visual fidelity, this combo delivers playable performance at every resolution, with the strongest results at 1080p and 1440p where frame rates exceed 100 FPS even at Ultra settings.
