Microsoft Flight Simulator

Resolution Scaling

The measured FPS data reveals a clear pattern: Microsoft Flight Simulator scales heavily with resolution, and the RTX 4070 Ti SUPER becomes the dominant factor as pixel count rises. At 1080p Ultra, the combo produces 108.2 FPS, which drops to 88.3 FPS at 1440p Ultra (an 18.4% reduction) and further to 61.6 FPS at 4K Ultra (a 43.1% reduction from 1080p). This steep decline indicates that at 4K, the GPU is thoroughly saturated, with the CPU having little influence on the final frame rate.

However, the scaling pattern changes dramatically at lower settings. At Low settings, the combo delivers 197.1 FPS at 1080p, 155.2 FPS at 1440p, and 111.5 FPS at 4K. The percentage drops between resolutions are more pronounced at Low settings compared to Ultra, suggesting that when graphical load is light, the CPU begins to matter more. Specifically, moving from 1080p Low to 1440p Low costs 21.3% performance, while the same resolution jump at Ultra only costs 18.4%. This differential indicates that at Low settings, the i5-14600K is partially limiting performance, preventing the GPU from fully stretching its legs.

The most telling observation comes from the Medium preset. At 1080p Medium, the combo hits 154.1 FPS, which is 42.4% higher than 1080p Ultra. Yet at 4K Medium, the score is 88.9 FPS, which is 44.3% higher than 4K Ultra. The consistency of these ratios across resolutions suggests that the RTX 4070 Ti SUPER's 16 GB VRAM and 672.3 GB/s bandwidth are sufficient to maintain steady scaling, with no sudden cliff drops that would indicate VRAM saturation.

CPU Role

The Intel Core i5-14600K brings 14 cores and 20 threads to this simulation, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. These specifications matter because Microsoft Flight Simulator is known for heavy single-threaded workloads, and the CPU's single-core strength is evident in its benchmark scores. The i5-14600K achieves a Cinebench R23 single-core score of 4642 and a Geekbench single-core score of 2803, both of which place it in the 93rd percentile among all CPUs.

The data shows that the CPU's influence on FPS is most visible at lower resolutions and settings. At 1080p Low, the combo produces 197.1 FPS, which represents the ceiling of what this pairing can achieve. This high frame rate is only possible because the CPU can feed frames quickly enough when the GPU is not heavily burdened. In contrast, at 4K Ultra, the CPU's role diminishes, as the GPU becomes the bottleneck, and the FPS drops to 61.6.

The i5-14600K's 24 MB of shared L3 cache and 2 MB per-core L2 cache contribute to its responsiveness in simulation workloads. The CPU's 10 nm process node and Raptor Lake architecture provide efficient execution, though the data does not isolate cache effects directly. What is clear is that the CPU's multi-core performance — highlighted by a Cinebench R23 multi-core score of 32881 — ensures that background simulation tasks (AI traffic, weather systems) do not starve the main render thread.

How This Combo Ranks

In the benchmark database, this specific combination of Intel Core i5-14600K and NVIDIA GeForce RTX 4070 Ti SUPER ranks 161st out of 1795 tested combos in Microsoft Flight Simulator. This places the pairing in the top 9% of all configurations, which is a strong result for a system built around a mid-range CPU and upper-mid-range GPU.

The CPU's nearest rivals in overall benchmark scores provide context for its performance tier. The AMD Ryzen 9 5950X scores 49062 on average, which is a mere 0.2% lower than the i5-14600K's 49166 average. This effectively means the two processors are performance equals in synthetic tests, though the i5-14600K edges ahead. The Intel Core i5-14600KF is 0.4% faster, and the AMD EPYC 4345P is 0.9% faster, while the Intel Xeon Gold 5318H is 1% slower. These tiny deltas indicate that the CPU is not a differentiator in this game; the GPU matters far more.

On the GPU side, the RTX 4070 Ti SUPER's nearest rivals show a similar clustering. The NVIDIA CMP 50HX is 0.7% faster, the RTX A2000 is 1.6% slower, the RTX A1000 Mobile is 2% slower, and the Intel Arc A550M is 2.1% faster. These small margins reinforce that the 4070 Ti SUPER sits in a competitive performance band, and its 86th percentile ranking among all GPUs is appropriate for its capabilities.

GPU Role

The NVIDIA GeForce RTX 4070 Ti SUPER is the star of this pairing for Microsoft Flight Simulator's visual demands. With 16 GB of GDDR6X memory on a 256-bit bus, the GPU provides 672.3 GB/s of bandwidth, which is essential for streaming the vast textures and scenery data that this game requires. The GPU's 8448 shading units and 66 RT cores (based on the Ada Lovelace architecture) handle the game's complex lighting and shadow calculations.

The GPU's clock speeds are notable: a base of 2340 MHz and a boost of 2610 MHz. These frequencies, combined with the 96 ROPs, enable a pixel rate of 250.6 GPixel/s and a texture rate of 689.0 GTexel/s. In practical terms, these specifications translate to the FPS figures we see: 108.2 FPS at 1080p Ultra, 88.3 FPS at 1440p Ultra, and 61.6 FPS at 4K Ultra.

The data confirms that the GPU is the primary driver of performance at higher settings. Moving from Medium to Ultra at 4K costs 27.3 FPS (from 88.9 to 61.6), a 30.7% penalty. This is a substantial hit that reflects the GPU's workload in rendering the game's dense scenery. The GPU's 285 W TDP and 600 W suggested PSU requirement indicate that it is a power-hungry component, but the measured FPS numbers justify the energy expenditure for users seeking high-fidelity flight simulation.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user's display resolution and performance priorities. At 1080p, Ultra settings deliver 108.2 FPS, which is above the 60 FPS threshold for smooth gameplay. This makes Ultra the recommended choice for 1080p users who want maximum visual fidelity without sacrificing playability.

For 1440p users, High settings provide 93.5 FPS, which is a solid balance. Ultra drops to 88.3 FPS, a 5.6% reduction that may not be visually noticeable in a flight simulator where camera movements are often slower. However, Medium settings at 119.1 FPS offer a significant 27.4% improvement over Ultra, making Medium the best choice for users with high-refresh-rate 1440p monitors.

At 4K, the recommendation is clearer. Ultra produces 61.6 FPS, which is playable but leaves little headroom for complex scenes with heavy cloud cover or dense urban areas. High settings at 68 FPS add a 10.4% margin, while Medium at 88.9 FPS offers a 44.3% improvement over Ultra. For 4K users, Medium or High is the pragmatic recommendation, with High being the sweet spot for those prioritizing visual quality.
