Microsoft Flight Simulator

Microsoft Flight Simulator places an unusual dual burden on a system, demanding both strong single-thread CPU performance for simulation logic and substantial GPU throughput for rendering dense scenery. The combination of the Intel Core i5-12600KF and AMD Radeon RX 5700 XT produces a balanced yet resolution-sensitive experience. The data shows a clear pattern: as resolution increases, the frame rate drops steeply, indicating a shift in the primary bottleneck from the processor at 1080p to the graphics card at 4K. This analysis walks through the measured FPS rows to explain how each component contributes to the final result.

Resolution Scaling

The measured FPS data reveals a pronounced scaling penalty as resolution climbs. At 1080p with High settings, the combo averages 61 FPS. Moving to 1440p drops this to 49 FPS, a reduction of roughly 20%. At 4K, the average falls to 37 FPS, which is about 39% lower than the 1080p result. This steep decline is typical for a GPU-bound scenario, where the number of pixels rendered becomes the dominant factor. The RX 5700 XT, with its 8 GB of GDDR6 memory and 448.0 GB/s of bandwidth, is being pushed harder at higher resolutions, and the data reflects that strain.

The pattern is consistent across all settings. With Low settings, 1080p yields 98.4 FPS, 1440p yields 80.1 FPS, and 4K yields 55.7 FPS. The percentage drop from 1080p to 4K is about 43%, which is slightly larger than the drop seen at High settings. This suggests that even on Low, the GPU is still the limiting factor at 4K, as the raw pixel count overwhelms the shading units and ROPs. At 1440p, the scaling is more moderate, with the frame rate staying above 80 FPS on Low, indicating that the CPU is still keeping up with the simulation load.

The limiting component shifts clearly between resolutions. At 1080p, the frame rates are high enough that the CPU's performance, particularly its single-thread capabilities, likely caps the maximum output. At 4K, the GPU's 9.754 TFLOPS of FP32 compute and 64 ROPs are the clear bottleneck, as the frame rates drop into the low 30s and high 50s depending on the preset. The data supports a conclusion that this combo is best suited for 1440p gaming, where the balance between the two components yields playable results without the extreme drops seen at 4K.

GPU Role

The AMD Radeon RX 5700 XT is a RDNA 1.0 architecture part with 2560 shading units and 160 texture mapping units. Its boost clock of 1905 MHz and game clock of 1755 MHz define its sustained performance envelope. The GPU's memory configuration is a critical factor: 8 GB of GDDR6 on a 256-bit bus provides 448.0 GB/s of bandwidth. In Microsoft Flight Simulator, which streams vast amounts of terrain and texture data, this bandwidth is essential. The measured FPS at 4K Ultra being 31.1 FPS shows that the card's memory subsystem and compute units are saturated, as the Ultra preset likely increases texture detail and draw distances.

The GPU's percentile rank against all GPUs is 68, indicating it sits above the median but is not a high-end part. Its nearest rivals include the NVIDIA RTX A5000 Mobile (deltaPct -0.1) and the Intel Arc A350M (deltaPct 0.3), which are close in aggregate benchmark scores. However, in this specific game, the RX 5700 XT's performance is more dependent on raw fill rate and bandwidth than on features like ray tracing, which this card lacks. The DirectX 12 benchmark score of 64 suggests moderate API efficiency, but the game's results indicate that the card is capable of handling 1080p and 1440p with reasonable settings.

The transition from Low to Ultra settings at 1080p shows the GPU's scaling headroom. Low produces 98.4 FPS, while Ultra produces 54.1 FPS, a reduction of 45%. This is a significant drop, but it demonstrates that the card has enough headroom to run higher presets if the user prioritizes visual fidelity over frame rate. At 4K, the same settings transition yields a drop from 55.7 to 31.1 FPS, a 44% reduction, showing that the GPU is consistently the limiting factor at this resolution regardless of the preset.

CPU Role

The Intel Core i5-12600KF is a 10-core, 16-thread processor based on the Alder Lake architecture. Its base clock of 3.70 GHz and boost clock of 4.90 GHz are crucial for the simulation-heavy workload of Microsoft Flight Simulator, which relies heavily on single-thread performance for flight physics and complex scenery processing. The CPU's single-thread benchmark scores are strong: 3DMark single-thread score is 1016, and Cinebench R23 single-core is 3309. These numbers indicate that the CPU can handle the game's logical updates without being a bottleneck at lower resolutions.

The CPU's multi-thread capabilities are also robust, with a Cinebench R23 multicore score of 23444 and a 3DMark 16-thread score of 7956. This parallel power helps with background tasks and asset streaming, but the game's primary thread load is what limits frame rates at 1080p. The measured FPS at 1080p Low is 98.4, which is close to the refresh rate of many monitors, suggesting the CPU is near its limit for pushing frames. The percentile rank of 84 versus all CPUs places it in the upper tier, and its nearest rival, the Intel Core i9-10900K, has a nearly identical average score (27829 vs 27827), indicating that the 12600KF is a strong performer for its generation.

The CPU's L3 cache of 20 MB (shared) helps with repeated data access, which is common in flight simulators as the same terrain tiles are loaded and reloaded. The memory support for both DDR4 and DDR5 provides flexibility, but the dual-channel bus width means memory bandwidth is not a primary constraint in this game's results. The data shows that at 1080p, the CPU is often the limiting factor, as frame rates plateau around 98 FPS on Low settings, while the GPU has more headroom.

Measured FPS Breakdown

The measured FPS table provides a complete picture of the combo's performance across three resolutions and four settings presets. At 1920x1080, the results are as follows: Low averages 98.4 FPS, Medium averages 79.2 FPS, High averages 61 FPS, and Ultra averages 54.1 FPS. This shows a steady decline as settings increase, with the gap between Low and Ultra being 44.3 FPS. The frame rates are all playable, but Ultra dips below 60 FPS, which may be a concern for users with high-refresh-rate displays.

At 2560x1440, the averages are: Low 80.1 FPS, Medium 62.4 FPS, High 49 FPS, and Ultra 42.8 FPS. The drop from 1080p to 1440p is consistent, with each preset losing roughly 18-20 FPS. This resolution strikes a good balance, as even High settings stay above 48 FPS, and Medium exceeds 60 FPS, providing a smooth experience for most users.

At 3840x2160, the averages are: Low 55.7 FPS, Medium 42.3 FPS, High 37 FPS, and Ultra 31.1 FPS. This is the most demanding scenario, and the results show that only Low settings approach playable territory, while Ultra falls below 32 FPS. The data indicates that 4K is only viable with significant settings reductions, and even then, the frame rate may not be stable enough for a fluid experience.

How This Combo Ranks

The combo's rank in Microsoft Flight Simulator is 1355 out of 1795 tested combinations. This places it in the lower-middle tier of all tested systems, which is consistent with its hardware profile. The GPU's 68th percentile and CPU's 84th percentile suggest that the CPU is the stronger component, but the GPU's limitations at higher resolutions drag the overall rank down. The data shows that this combo performs best at 1080p and 1440p, where the CPU can leverage its high single-thread scores to keep frame rates competitive.

Comparing to the nearest rivals, the CPU is nearly identical in average score to the Intel Core i9-10900K (deltaPct 0), meaning that swapping in a more powerful GPU would likely yield similar CPU-bound results. The GPU's nearest rivals, such as the RTX A5000 Mobile, have a deltaPct of -0.1, indicating they are statistically tied in aggregate benchmarks. However, in this specific game, the RX 5700 XT's performance is what it is, and the rank reflects the practical outcome of these two components working together.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution. At 1080p, the High preset at 61 FPS offers a good balance between visual quality and smoothness, while Medium at 79.2 FPS provides a more comfortable margin above 60 FPS for users who prioritize frame rate. Ultra is playable at 54.1 FPS, but the slight drop below 60 FPS may introduce noticeable stutter on some displays.

At 1440p, the Medium preset at 62.4 FPS is the recommended choice, as it provides a smooth frame rate while still maintaining decent visual fidelity. High at 49 FPS is acceptable for slower-paced gameplay, but it may feel less responsive. Low at 80.1 FPS is ideal for competitive or smoothness-focused users, but it sacrifices visual detail.

At 4K, only the Low preset at 55.7 FPS is recommended, as it approaches playable levels. Medium drops to 42.3 FPS, which is borderline, and High and Ultra fall below 40 FPS, making them unsuitable for a consistent experience. The data suggests that this combo is not intended for 4K gaming, and users should either lower their resolution or accept significant compromises. For the best overall experience, 1440p with Medium settings provides the highest frame rate per visual detail ratio, making it the sweet spot for this hardware configuration.
