Microsoft Flight Simulator

Microsoft Flight Simulator is a notoriously demanding title, and the pairing of the Intel Core i7-14700KF with the AMD Radeon RX 6800 XT produces a clear, predictable scaling pattern. The data shows a system that is firmly GPU-limited at higher resolutions, but the CPU's substantial headroom becomes the defining factor at 1080p, allowing for exceptional frame rates. This combination ranks 620th out of 1795 tested combos, placing it in the top third of all configurations. The following analysis breaks down the measured performance to help you understand exactly where this rig excels and where its limits lie.

Resolution Scaling

The measured FPS data reveals a textbook case of resolution-driven performance scaling. At 1080p with Low settings, the combo achieves 149.6 FPS, but this drops to 122.9 FPS at 1440p and further to 88.3 FPS at 4K. This represents a 41% reduction in frame rate from 1080p to 4K at Low settings, indicating that the rendering load is scaling heavily with pixel count. The RX 6800 XT's 16 GB of GDDR6 memory and 512.0 GB/s bandwidth are sufficient for the 4K frame buffer, but the raw compute demand of 4K is what brings performance down.

The scaling pattern shifts with settings presets. At Ultra settings, the drop from 1080p (85.8 FPS) to 1440p (66.8 FPS) is a 22% decrease, and then to 4K (46.9 FPS) is another 30% decrease. This steeper curve at higher presets suggests that the game's Ultra settings introduce effects that disproportionately tax the GPU at higher resolutions. Conversely, at Medium settings, the 1080p to 1440p drop is 22% (from 121.6 to 94.3 FPS), and the 1440p to 4K drop is 26% (from 94.3 to 69.8 FPS), showing a more consistent scaling.

The key takeaway is that 4K gaming at Ultra is not viable with this combo, as the 46.9 FPS result falls below the 60 FPS threshold. However, 4K at High settings (53.3 FPS) is borderline playable, and 4K at Medium (69.8 FPS) provides a smooth experience. At 1440p, this system hits a sweet spot, with High settings delivering 69.5 FPS and Medium delivering 94.3 FPS. The data indicates that the RX 6800 XT is the limiting component at 4K, as the CPU's performance headroom cannot compensate for the GPU's pixel-pushing limitations.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor based on the Raptor Lake architecture. Its base clock of 3.40 GHz and boost clock of 5.60 GHz provide the single-thread performance that Microsoft Flight Simulator relies on for its simulation logic and draw call processing. The CPU's benchmark results support this: a Cinebench R23 single-core score of 6290 and a Geekbench single-core score of 2972 indicate strong per-core performance, which is critical for this game's engine.

The multi-core performance is equally formidable, with a Cinebench R23 multi-core score of 44557 and a Passmark multithread score of 52425. The 33 MB of shared L3 cache and 2 MB per-core L2 cache help keep frequently accessed data close to the cores. The CPU's 96th percentile ranking among all CPUs confirms its high-end status. In this game, the CPU's role is to feed the GPU with enough data to avoid bottlenecks, and the data shows it does so effectively.

The evidence of the CPU's headroom is visible in the 1080p Low results. At 149.6 FPS, the system is not CPU-bound, as the GPU is still able to render at a high frame rate. If the CPU were the limitation, we would see a plateau in FPS across lower resolutions, but the steady increase from 4K to 1080p suggests the GPU remains the bottleneck even at 1080p. The CPU's nearest rival, the Intel Core i7-14700K, has a nearly identical average score (70074 vs 70104 for the KF), with a deltaPct of 0%, meaning the KF variant offers no performance advantage in synthetic benchmarks. This suggests that the unlocked multiplier on the KF is the primary differentiator, not raw speed.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend heavily on your target resolution and refresh rate. At 4K, the Medium preset is the clear recommendation, delivering 69.8 FPS. This is a 31% improvement over High (53.3 FPS) and a 49% improvement over Ultra (46.9 FPS), making it the only preset at 4K that comfortably exceeds 60 FPS. The step from Low (88.3 FPS) to Medium (69.8 FPS) costs 21% performance but likely provides a substantial visual uplift, making Medium the best balance.

For 1440p, High settings are the sweet spot. The 69.5 FPS average is playable, but if you have a 144Hz or 165Hz display, Medium at 94.3 FPS is a better choice. The data shows that Ultra at 1440p (66.8 FPS) is only 4% slower than High, so if you prioritize visual fidelity over a high refresh rate, Ultra is viable. However, the jump from Medium to High only costs 26% performance (from 94.3 to 69.5 FPS), which is a reasonable trade for better visuals.

At 1080p, the system has plenty of headroom. Low settings hit 149.6 FPS, which is suitable for competitive play or high-refresh-rate monitors. Medium at 121.6 FPS is a strong all-around choice, while High at 91.1 FPS still offers a smooth experience. Ultra at 85.8 FPS is the most visually demanding preset and remains playable. The recommendation is to use Medium at 1080p for a balance of visual quality and frame rate, as it provides a 34% uplift over High while maintaining a high refresh rate.

How This Combo Ranks

The combination of the Intel Core i7-14700KF and AMD Radeon RX 6800 XT ranks 620th out of 1795 tested combos in Microsoft Flight Simulator, placing it in the 65th percentile of all configurations. This is a strong result, but it is not at the very top tier. The CPU's 96th percentile ranking among all processors is higher than the GPU's 87th percentile ranking among all graphics cards, which explains why the combo ranks lower than the sum of its parts might suggest. The GPU is the weaker link in this pairing.

The GPU's nearest rivals provide context. The NVIDIA GeForce RTX 4070 Ti SUPER has an average score that is 2.6% lower than the RX 6800 XT, meaning the AMD card holds a slight edge in synthetic benchmarks. The Intel Arc A550M is 0.5% ahead, and the NVIDIA CMP 50HX is 1.9% behind. These are all close scores, indicating that the RX 6800 XT is competitive with modern mid-to-high-end GPUs. However, the CPU's rivals are even closer, with the Intel Core i7-14700K being exactly 0% apart, and the AMD Ryzen 9 9950X being 0.4% ahead.

This ranking data suggests that the combo is well-balanced but not optimized for maximum frame rates in this specific title. The 620th rank out of 1795 means there are 1175 other combos that perform better, which is a significant number. This is likely due to the GPU's 16 GB memory being sufficient but not exceptional, and the CPU's power being underutilized at lower resolutions where the GPU becomes the bottleneck.

The data confirms that this system delivers its best performance at 1080p, where all presets exceed 85 FPS. At 1440p, the system remains capable, with only Ultra settings dipping below 70 FPS. At 4K, the system is limited to Medium settings for a smooth experience, as High and Ultra fall below 60 FPS. The RX 6800 XT's 16 GB memory and 4608 shading units are sufficient for 4K, but the 20.74 TFLOPS of FP32 performance is not enough to maintain high frame rates at Ultra settings in this demanding title.
