Resolution Scaling

The measured FPS data reveals how performance scales across resolutions. At 1080p Low, the combo delivers 235.1 FPS. Moving to 1440p Low drops this to 183.4 FPS, a 22% reduction. At 4K Low, the average falls to 132.4 FPS, another 28% decrease. This pattern shows that even at Low settings, the GPU's workload increases substantially with resolution, as the RTX 4090's 24 GB of GDDR6X memory and 1.01 TB/s bandwidth are taxed by higher pixel counts.

The scaling becomes more pronounced at higher settings. For Ultra, the progression is 129.5 FPS at 1080p, 103.3 FPS at 1440p, and 75.1 FPS at 4K. The drop from 1080p to 1440p is 20%, but from 1440p to 4K it accelerates to 27%. This non-linear scaling indicates that the GPU's shading units (16,384) and texture units (512) are increasingly saturated as resolution climbs, with the 4K Ultra scenario pushing the card to its limits.

The data points to the RTX 4090 as the limiting component at 4K across all settings. At 1080p Low, the 235.1 FPS figure suggests the CPU may be the bottleneck, as the i7-14700K's boost clock of 5.60 GHz and 20 cores provide ample headroom, but the frame rate is still extraordinarily high. At 1440p and above, the GPU's FP32 throughput of 82.58 TFLOPS becomes the primary driver, with the CPU's role diminishing as resolution increases.

Measured FPS Breakdown

At 3840x2160, the combo produces 132.4 FPS on Low, 108.6 FPS on Medium, 78 FPS on High, and 75.1 FPS on Ultra. The jump from Low to Medium is a 18% drop, while Medium to High is a 28% drop. High to Ultra is a modest 3.7% decline, suggesting that Ultra settings at 4K are only slightly more demanding than High, likely due to diminishing returns on certain graphical effects.

Moving to 2560x1440, the figures are 183.4 FPS on Low, 144.4 FPS on Medium, 107 FPS on High, and 103.3 FPS on Ultra. The Low to Medium drop is 21%, Medium to High is 26%, and High to Ultra is 3.5%. This mirrors the 4K pattern, with the largest gap occurring between Medium and High, indicating a significant increase in GPU workload at that tier.

At 1920x1080, the results are 235.1 FPS on Low, 179.4 FPS on Medium, 135.6 FPS on High, and 129.5 FPS on Ultra. The Low to Medium drop is 24%, Medium to High is 24%, and High to Ultra is 4.5%. Across all resolutions, the High-to-Ultra transition consistently costs the least in terms of FPS, making Ultra an attractive option for users seeking maximum visual fidelity without a substantial performance penalty.

CPU Role

The Intel Core i7-14700K features 20 cores and 28 threads, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its 33 MB of shared L3 cache and 2 MB per-core L2 cache provide ample capacity for flight simulation's complex scenery and physics calculations. The CPU's benchmark scores are strong, with a Cinebench R23 multi-core result of 44,534 and a single-core score of 6,287, placing it in the 96th percentile of all CPUs.

For Microsoft Flight Simulator, which relies heavily on single-thread performance for game logic and physics, the i7-14700K's boost clock of 5.60 GHz is critical. The data shows that at 1080p Low, the combo hits 235.1 FPS, a figure that suggests the CPU is keeping pace with the GPU's output. However, the CPU's 20 cores are not fully utilized in this title, as the game's engine typically scales to fewer threads, but the high clock speed ensures that the primary simulation thread does not become a bottleneck.

The nearest CPU rival, the i7-14700KF, has a delta of 0% in average benchmark score, confirming that the integrated UHD Graphics 770 on the i7-14700K does not impact gaming performance when a discrete GPU is present. The AMD Ryzen 9 9950X, which scores 0.5% higher, may offer similar gaming performance, but the i7-14700K's higher boost clock gives it an edge in single-threaded workloads. The data indicates that the CPU's role is most pronounced at lower resolutions, where frame rates exceed 180 FPS, but at 4K, the GPU dominates the performance equation.

Settings Recommendations

For users prioritizing maximum frame rate, the Low preset at 1920x1080 delivers 235.1 FPS, which is ideal for competitive or high-refresh-rate displays. However, this setting sacrifices visual fidelity, which is often a priority in flight simulators. At 1440p Low, the 183.4 FPS figure still provides a smooth experience, while 4K Low at 132.4 FPS remains playable.

The Medium preset offers a balanced trade-off. At 1080p, it delivers 179.4 FPS, at 1440p it hits 144.4 FPS, and at 4K it maintains 108.6 FPS. This setting likely enables more detailed textures and effects without the steep performance hit seen at High. For users with 1440p monitors, Medium provides a strong combination of visuals and speed.

The High preset is the most demanding tier before Ultra. At 1080p, it produces 135.6 FPS, at 1440p it drops to 107 FPS, and at 4K it falls to 78 FPS. These figures are all above 60 FPS, making High a viable option for 4K users who want improved graphics without dropping below playable rates. The Ultra preset, which costs only 3-4% FPS compared to High, is recommended for users with 4K displays who have already invested in this high-end combo, as it yields 75.1 FPS at 4K.

Given the data, the optimal experience depends on the display resolution. For 1080p, Medium at 179.4 FPS offers the best balance of speed and quality, as the step to High costs 24% performance. For 1440p, Medium at 144.4 FPS is similarly recommended, as High is 26% slower. At 4K, the choice between High (78 FPS) and Ultra (75.1 FPS) is nearly negligible, so Ultra is the clear recommendation for maximum visual fidelity. Users with high refresh-rate 1080p or 1440p displays should consider Low settings to maximize FPS, but the data shows that this combo can handle Medium at all resolutions without dropping below 100 FPS.
