Microsoft Flight Simulator

The Intel Core i5-12400 paired with the Intel Arc B580 delivers a playable, if not entirely smooth, Microsoft Flight Simulator experience, with the data clearly showing a GPU-bound configuration at higher resolutions. The measured results indicate that this combination is best suited for 1080p and 1440p gaming, where it can achieve respectable frame rates, while 4K Ultra settings remain out of reach for a fluid experience.

Resolution Scaling

The performance drop from 1080p to 4K is steep, revealing the Arc B580 as the primary limiting factor. At High settings, the average frame rate falls from 57.3 FPS at 1920x1080 to 42.4 FPS at 2560x1440, a reduction of roughly 26%. The slide continues to 33.7 FPS at 3840x2160, which is a 41% decline from the 1080p baseline. This scaling pattern is classic evidence of a GPU bottleneck; the CPU has enough headroom to feed frames at lower resolutions, but the graphics card's rendering throughput cannot keep pace as pixel count increases.

The trend holds across all settings. At Low, the frame rate drops from 95.1 FPS at 1080p to 76.4 FPS at 1440p and then to 57.1 FPS at 4K. The 4K Low result is telling: even with the graphical load minimized, the Arc B580 can only muster 57.1 FPS, which is below the 60 FPS threshold many players target. This suggests that for a locked 60 FPS experience at 4K, this combo would require even lower settings or a resolution scaling feature, neither of which is present in the measured data. The frame rate drop from 1440p to 4K is proportionally larger than from 1080p to 1440p, reinforcing that the GPU is being saturated at the highest resolution.

CPU Role

The Intel Core i5-12400 provides a solid foundation for this flight simulator. With 6 cores and 12 threads, it offers sufficient parallel processing for the game's complex simulation logic, which often involves numerous background calculations for weather, physics, and AI traffic. Its boost clock of 4.40 GHz ensures strong single-thread performance, which remains critical for the main game thread. The CPU's benchmark scores support this: a Cinebench R23 multicore score of 15935 and a single-core score of 2249 indicate a well-balanced processor that is unlikely to be the primary constraint in this title.

The data suggests the CPU is not the bottleneck, especially at higher resolutions. When comparing the 1080p Low result of 95.1 FPS to the 1440p Low result of 76.4 FPS, the CPU is clearly capable of pushing well beyond 76 FPS in this scenario. The fact that the frame rate drops as resolution increases is a direct sign that the CPU's work is not the limiting factor. The i5-12400's performance is competitive with its rivals, as it sits within 0.4% of the Intel Core i5-11600K and 0.1% of the Intel Core i7-9700 in average benchmark score. This places it in a strong position to feed the Arc B580 with data, but the GPU cannot fully translate that CPU capability into high frame rates at 4K.

GPU Role

The Intel Arc B580 is the decisive component in this configuration, and its 12 GB of VRAM and 456.0 GB/s of memory bandwidth are substantial assets for a game like Microsoft Flight Simulator, which loads vast textures for terrain and aircraft. The GPU's 20 ray tracing cores and 2560 shading units are modern specifications, but the measured frame rates show that raw throughput is the limiting factor at higher resolutions. The GPU's average benchmark score of 23021 places it just 0.7% behind the NVIDIA GeForce RTX 4060, indicating it is a comparable performer in synthetic tests.

However, in this specific game, the Arc B580's performance is heavily dependent on settings. The transition from Low to Medium at 1080p yields a significant drop from 95.1 FPS to 74.9 FPS, a 21% penalty. Moving from Medium to High further reduces the frame rate to 57.3 FPS, and Ultra brings it down to 55.5 FPS. This shows that the GPU is very sensitive to the increased shader and texture demands of higher presets. The 4K Ultra result of 28.8 FPS is indicative of the GPU being fully saturated, rendering the scene at a pace that is not fluid. The GPU's 2670 MHz clock speed is consistent across base and boost, suggesting it runs at a stable frequency, but the architecture's overall compute capacity is what determines these results.

Settings Recommendations

Based on the measured data, the optimal experience balances visual fidelity with a playable frame rate. For 1920x1080, the High preset at 57.3 FPS is the best recommendation. It offers a significant visual upgrade over Medium (74.9 FPS) while staying above the 50 FPS threshold for acceptable smoothness in a sim. The Ultra preset at 55.5 FPS provides only a marginal frame rate improvement over High, which is a poor trade for the likely increase in visual complexity, making High the smarter choice.

At 2560x1440, the Medium preset at 62.8 FPS is the sweet spot. It delivers a smooth frame rate well above 60 FPS, while the High preset at 42.4 FPS is too choppy for a game that requires precise control. The Low preset at 76.4 FPS is fast but sacrifices too much visual detail for a flight sim where terrain clarity is important. For 3840x2160, the Low preset at 57.1 FPS is the only viable option for a semi-fluid experience, but players seeking a more visually rich 4K experience will find the Medium (43.2 FPS) and High (33.7 FPS) presets to be too slow for comfortable play.

FAQ

Q: Can this combo run Microsoft Flight Simulator at 4K?

A: Yes, but only at Low settings, where it achieves an average of 57.1 FPS. Higher presets at 4K result in sub-45 FPS performance, with Ultra dipping to 28.8 FPS.

Q: Is the CPU or GPU the bottleneck at 1440p?

A: The GPU is the bottleneck. The frame rate drops from 76.4 FPS at Low settings to 42.4 FPS at High settings, showing that the Arc B580's rendering load is the limiting factor, not the Core i5-12400's processing power.

Q: What is the best setting for a 60 FPS target at 1080p?

A: The Medium preset at 74.9 FPS is the only measured setting that exceeds 60 FPS. The High preset falls short at 57.3 FPS.

Q: How does the Arc B580 compare to a GeForce RTX 4060 in this game?

A: The Arc B580's average benchmark score is 23021, which is 0.7% lower than the RTX 4060's score of 23181. This suggests they are closely matched, but the specific frame rates in this game are not provided for the RTX 4060.

Q: Does the 12 GB VRAM help at 4K?

A: The 12 GB VRAM is likely sufficient for the game's textures at 4K, but it does not overcome the GPU's compute limits. The low frame rates at 4K indicate that raw processing power, not memory capacity, is the primary constraint.

Q: What is the frame rate difference between Low and Ultra at 1440p?

A: The Low preset produces 76.4 FPS, while Ultra produces 41.7 FPS. This represents a 45% reduction in frame rate for the highest visual quality.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are 95.1 FPS on Low, 74.9 FPS on Medium, 57.3 FPS on High, and 55.5 FPS on Ultra. This shows a clear progression where the first major performance hit occurs between Low and Medium, with subsequent steps having a smaller impact.

At 2560x1440, the results are 76.4 FPS on Low, 62.8 FPS on Medium, 42.4 FPS on High, and 41.7 FPS on Ultra. The gap between Medium and High is substantial here, representing a 32% drop in performance.

At 3840x2160, the data shows 57.1 FPS on Low, 43.2 FPS on Medium, 33.7 FPS on High, and 28.8 FPS on Ultra. The frame rate at 4K High is less than half of the 1080p Low result, demonstrating the significant rendering cost at this resolution.

How This Combo Ranks

This specific configuration of the Intel Core i5-12400 and Intel Arc B580 ranks 1414th out of 1795 tested combos in Microsoft Flight Simulator. This places it in the lower percentile of all tested systems, indicating that while it is functional, it is not a high-performance combination for this title. The rank is likely dragged down by the GPU's performance at higher resolutions, as the CPU is a capable mid-range part. The data shows that this combo is positioned for 1080p gaming, where it can deliver acceptable frame rates, but it falls behind many other pairings at 1440p and 4K. The overall ranking reflects a system that is adequate for entry-level to mid-range flight simulation, but it will not satisfy enthusiasts seeking maximum visual fidelity at high resolutions.
