Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data for Microsoft Flight Simulator reveals a predictable but telling scaling pattern as resolution increases. At 1080p with Low settings, the combination of the Intel Core i9-14900K and AMD Radeon RX 9070 delivers 157 FPS. Moving to 1440p drops that to 121.6 FPS, a decline of roughly 23%. At 4K, the Low preset yields 90.9 FPS, which is 42% below the 1080p figure. This scaling curve is relatively gentle, which suggests the CPU is still heavily involved in determining frame rates even at lower resolutions.

The picture changes when examining the Ultra preset. At 1080p Ultra, the combo produces 86.8 FPS. At 1440p Ultra, it falls to 69.3 FPS, and at 4K Ultra, it reaches 49.9 FPS. The percentage drop from 1080p to 1440p is about 20%, while the drop from 1440p to 4K is roughly 28%. This steeper decline at higher resolutions indicates that the GPU begins to take on a more dominant limiting role as pixel count rises. The data implies that at 1080p, the i9-14900K's 24 cores and 32 threads are feeding frames fast enough that the RX 9070 becomes the bottleneck even on lower presets, but the effect is more pronounced at 4K where raw pixel throughput matters most.

What is notable is that the gap between Low and Ultra settings narrows as resolution increases. At 1080p, the spread between Low (157 FPS) and Ultra (86.8 FPS) is 70.2 FPS. At 4K, that spread compresses to 41 FPS (90.9 vs 49.9). This compression is a classic sign of GPU saturation: when the render target grows, the cost of each frame increases, and the relative impact of graphical settings diminishes because the GPU is already working near its limits. The 16 GB of GDDR6 memory on the RX 9070 appears sufficient across all tested configurations, as no min-FPS anomalies suggest memory swapping.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 9070 brings 16 GB of GDDR6 memory across a 256-bit bus, delivering 644.6 GB/s of bandwidth. In a flight simulator like Microsoft Flight Simulator, which streams vast geographic scenery and detailed aircraft models, this memory capacity and bandwidth are critical. The data shows that even at 4K Ultra, the GPU never falls below 49.9 FPS on average, suggesting the 16 GB frame buffer is not being exhausted by the game's asset streaming demands.

The GPU's clock behavior is worth examining. The base clock is 1330 MHz, but the boost clock reaches 2520 MHz, with a game clock rated at 2070 MHz. The effective memory speed is 20.1 Gbps. These figures indicate a substantial overclocking headroom out of the box, which likely helps maintain consistent frame rates across different resolutions. At 1080p Low, the GPU produces 157 FPS, which is a strong result for a card that also manages 49.9 FPS at 4K Ultra. This range demonstrates flexibility, but the benchmark scores paint a nuanced picture.

The RX 9070's average benchmark score is 34,780, placing it in the 79th percentile. Its nearest rival, the NVIDIA A2, scores 34,866, a negligible 0.2% difference. This tight clustering suggests that the GPU's raw compute is competitive with similar-tier cards, but the measured FPS in this game depends heavily on how well the drivers handle Microsoft Flight Simulator's specific rendering path. The GPU's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 compatibility are relevant, as the game can leverage modern APIs. The 56 ray accelerators on the RDNA 4.0 architecture may also contribute to the game's lighting effects, though the data does not isolate ray tracing performance.

Settings Recommendations — which preset gives the best experience per the measured rows

Examining the measured FPS rows, the Medium preset consistently offers the best balance between visual fidelity and performance across all three resolutions. At 1080p, Medium yields 121.4 FPS, which is 35.6 FPS higher than High (92.5 FPS) and only 35.6 FPS lower than Low (157 FPS). At 1440p, Medium produces 96.3 FPS, which remains comfortably above the 60 FPS threshold for smooth gameplay, while High drops to 70.7 FPS and Ultra falls to 69.3 FPS. At 4K, Medium achieves 69.3 FPS, which is playable, whereas High drops to 52.6 FPS and Ultra to 49.9 FPS.

The Ultra preset is the only one that dips below 50 FPS at 4K, which may be undesirable for a flight simulator where smooth camera panning is essential. Low settings at 4K produce 90.9 FPS, but the visual quality loss is likely too severe for a game that emphasizes scenery fidelity. For users with high-refresh-rate 1080p displays, Medium at 121.4 FPS is the sweet spot, offering a near-60% improvement over High without the visual degradation of Low. At 1440p, Medium's 96.3 FPS is ideal for 60-100 Hz monitors. At 4K, Medium's 69.3 FPS is recommended, as it stays above 60 FPS while providing better detail than Low.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The complete set of measured results provides a clear performance matrix. At 1920x1080, the average FPS values are: Low at 157, Medium at 121.4, High at 92.5, and Ultra at 86.8. The step from Low to Medium costs 35.6 FPS, while the step from Medium to High costs 28.9 FPS, and the final step to Ultra costs only 5.7 FPS. This diminishing return suggests that the High and Ultra presets impose similar graphical loads at 1080p, likely due to CPU limitations.

At 2560x1440, the results are: Low at 121.6, Medium at 96.3, High at 70.7, and Ultra at 69.3. The gap between High and Ultra narrows to just 1.4 FPS, indicating that Ultra's additional effects have minimal impact at this resolution. The drop from Low to Medium is 25.3 FPS, and from Medium to High is 25.6 FPS, showing a consistent cost per settings tier until the Ultra plateau.

At 3840x2160, the values are: Low at 90.9, Medium at 69.3, High at 52.6, and Ultra at 49.9. Here, the cost of moving from Low to Medium is 21.6 FPS, and from Medium to High is 16.7 FPS. The Ultra preset is only 2.7 FPS lower than High, which again indicates that the GPU is the dominant bottleneck at 4K, and the difference between High and Ultra is negligible in practice. This data suggests that users on 4K displays should prioritize Medium or High, as Ultra offers marginal gains over High while demanding more from the hardware.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i9-14900K is a 24-core, 32-thread processor based on the Raptor Lake architecture, with a base clock of 3.20 GHz and a boost clock of 6.00 GHz. Its 36 MB of shared L3 cache and 2 MB per-core L2 cache provide substantial on-die storage for game data. In Microsoft Flight Simulator, which is known for heavy single-threaded simulation logic, the high boost clock is critical. The CPU's benchmark scores are impressive: a Cinebench R23 multi-core score of 49,872 and a single-core score of 7,040, along with a Geekbench single-core score of 3,064. These figures place the CPU in the 97th percentile among all tested CPUs.

The nearest rivals show how tight the competition is at the top. The AMD EPYC 7413 scores 80,041, which is 0.3% higher than the i9-14900K's 79,824 average. The Intel Core i9-14900KF scores 79,245 (0.7% lower), and the Intel Core Ultra 7 265KF scores 79,240 (0.7% lower). The differences are within a single percentage point, suggesting that for this game, the CPU's raw processing power is more than sufficient, and the frame rate is rarely CPU-bound except at lower resolutions.

The data supports this interpretation. At 1080p Low, the combo hits 157 FPS, which is likely near the CPU's limit for frame generation in this simulation. The fact that 1080p Ultra (86.8 FPS) is only 5.7 FPS lower than High (92.5 FPS) indicates that the CPU is still feeding frames quickly enough that the GPU's workload differences between High and Ultra are the primary factor. However, at 4K, the CPU's advantage is less visible, as the GPU becomes the limiting component. The 125 W TDP and dual-channel DDR4/DDR5 memory support are standard for this class, but the data does not suggest memory bandwidth is a bottleneck, given the consistent scaling across resolutions.

How This Combo Ranks — use comboRankInGame vs other tested combos

In the context of all tested configurations for Microsoft Flight Simulator, this specific pairing of the Intel Core i9-14900K and AMD Radeon RX 9070 ranks 583rd out of 1,795 combos. This places it in the 67.5th percentile, meaning it outperforms roughly two-thirds of all tested systems in this game. Given the CPU's strong benchmark standing (97th percentile) and the GPU's more modest position (79th percentile), this ranking suggests that the GPU is the limiting factor in the overall combo performance.

The rank of 583 is informative when compared to the individual component standings. The CPU is near the top of its class, but the GPU sits in the upper-middle tier. This imbalance indicates that the RX 9070 is holding back the i9-14900K in this game, particularly at higher resolutions where the GPU's workload is heavier. The measured FPS data corroborates this: at 1080p, the combo achieves 157 FPS on Low, which is excellent, but at 4K Ultra, it falls to 49.9 FPS, which is below the 60 FPS target many players prefer.

The ranking also implies that there are 582 combos that perform better, likely those with higher-tier GPUs paired with similar or slightly lower CPUs. The data does not specify which combos rank higher, but the implication is clear: for users prioritizing Microsoft Flight Simulator at 4K, a more powerful GPU would yield a better ranking. Conversely, for 1080p gamers, this combo's rank is likely higher than the overall figure suggests, as the CPU's strength shines at lower resolutions. The 583rd rank is a holistic measure, and the resolution-specific FPS data provides a more granular view of where this combo excels and where it falls short.
