Microsoft Flight Simulator

This combo of an Intel Core i5-14600K and NVIDIA GeForce RTX 4070 delivers a solid, high-refresh-rate experience in Microsoft Flight Simulator at 1440p and 1080p, while 4K requires a slight settings compromise. The measured data shows that at 2560x1440, every preset from Low to Ultra clears the 60 FPS threshold, with Ultra averaging 75.8 FPS. At 1920x1080, the headroom is even larger, with Ultra hitting 94.2 FPS. The only resolution where the GPU struggles to maintain 60 FPS on the highest settings is 3840x2160, where Ultra drops to 54.9 FPS, but dropping to Medium restores smooth performance at 72.8 FPS.

How This Combo Ranks

Out of 3,714 tested combos in this game, the Core i5-14600K plus RTX 4070 pairing ranks 831st. That places it in the top 22% of all configurations tested, which is a strong result for a mainstream desktop build. The ranking reflects the balance between the CPU and GPU, where neither component bottlenecks the other excessively in this title.

The CPU itself sits in the 90th percentile among all CPUs tested, with an average benchmark score of 48,618. Its nearest rivals are tightly clustered: the Intel Xeon Gold 5318H scores 48,698 (0.2% higher), the AMD EPYC 4345P scores 48,470 (0.3% lower), and the Intel Core Ultra 5 245HX scores 48,287 (0.7% lower). This means the i5-14600K is essentially at parity with much more expensive workstation and server parts in raw compute, which is notable for a 14-core desktop chip.

The GPU ranks in the 81st percentile among all GPUs, with an average score of 37,648. Its closest rivals include the NVIDIA Tesla P4 (37,628, 0.1% higher), the AMD Radeon RX Vega 56 (37,507, 0.4% lower), and the NVIDIA GeForce RTX 4080 Mobile (38,135, 1.3% higher). The RTX 4070 is competitive with these parts, though the gap to the RTX 4080 Mobile is small enough to be within run-to-run variance.

The rank of 831 out of 3,714 suggests that while this combo is not at the very top tier, it sits in a comfortable performance band where most games, including demanding simulators, will run well at high refresh rates. The data indicates a well-matched pair, as the CPU's strong single-thread performance complements the GPU's rasterization capabilities for a game that relies heavily on both.

CPU and GPU Roles

Microsoft Flight Simulator is known for being demanding on both the processor and the graphics card, but the measured FPS scaling across resolutions reveals how the balance shifts. At 3840x2160, the GPU is clearly the limiting factor. Dropping from Ultra to Low at 4K increases average FPS from 54.9 to 96.2, a massive 75% improvement purely from reducing graphics load. This indicates that at 4K, the RTX 4070's rasterization throughput is the primary constraint, and the CPU has enough headroom to feed it even at lower settings.

At 2560x1440, the scaling is less dramatic but still GPU-bound. Going from Ultra (75.8 FPS) to Low (133.4 FPS) yields a 76% lift, similar to 4K. However, the absolute numbers are higher, showing that the GPU has more spare capacity at this resolution. The CPU's role becomes more apparent when comparing the jump from Medium to Ultra at 1440p: the difference is 102.4 FPS to 75.8 FPS, a 26% drop. This suggests that the higher graphical settings are increasingly taxing the GPU's memory bandwidth and shading units, while the CPU maintains consistent frame pacing.

At 1920x1080, the CPU starts to matter more. Low settings produce 165.2 FPS, which is a 71% increase over Ultra's 94.2 FPS. But the fact that even Ultra stays above 90 FPS indicates that the i5-14600K's 14 cores and 20 threads are sufficient to keep up with the GPU's output at this resolution. The data shows that as resolution decreases, the CPU's single-thread performance becomes more critical for maintaining high frame rates, but this combo handles 1080p Ultra without issue.

The verdict by resolution confirms this pattern. At 4K, only Low and Medium are playable (above 60 FPS), while at 1440p and 1080p, all four presets are playable. This clearly indicates that the GPU is the bottleneck at 4K, while the CPU has enough power to support the GPU at lower resolutions.

Q: Is the i5-14600K a strong match for the RTX 4070 in this game?

A: Yes. The CPU ranks in the 90th percentile among all CPUs, and its nearest rival, the Intel Xeon Gold 5318H, is only 0.2% faster on average. This provides enough headroom to avoid bottlenecking the GPU at 1080p and 1440p.

Q: What is the worst-case FPS scenario for this combo?

A: The lowest average FPS recorded is 54.9 at 4K Ultra. At 4K High, the average is 57.9 FPS, which is also below the 60 FPS threshold. All other tested settings at all resolutions are above 60 FPS.

The Verdict

This PC can run Microsoft Flight Simulator, but the experience depends heavily on your target resolution. At 1920x1080, the combo delivers excellent performance across the board: Ultra settings average 94.2 FPS, High averages 98.6 FPS, Medium 128.9 FPS, and Low 165.2 FPS. All presets clear the 60 FPS threshold with significant headroom, making 1080p the sweet spot for this configuration.

At 2560x1440, the system remains fully playable at every preset. Ultra averages 75.8 FPS, which is comfortably above the 60 FPS line. High (76.5 FPS), Medium (102.4 FPS), and Low (133.4 FPS) all provide smooth performance. This makes 1440p a viable option for users who want higher visual fidelity without sacrificing frame rate.

At 3840x2160, you must compromise on settings. Ultra (54.9 FPS) and High (57.9 FPS) both fall short of 60 FPS, making them less than ideal for a smooth experience. Dropping to Medium yields 72.8 FPS, and Low jumps to 96.2 FPS. The verdict by resolution lists Low and Medium as the playable settings at 4K, with Medium being the best choice at 72.8 FPS.

For a flight simulator where frame pacing matters for smooth camera pans and instrument readability, sticking to 1440p Ultra or 1080p Ultra is recommended. At 4K, you will need to accept Medium settings to stay above 60 FPS, which still looks good but sacrifices some of the visual richness that makes the game immersive.

Measured FPS Breakdown

The measured data provides average FPS for each resolution and preset combination. No minimum or maximum FPS values were recorded, so the analysis relies on averages.

At 3840x2160:

• Low: 96.2 FPS average
• Medium: 72.8 FPS average
• High: 57.9 FPS average
• Ultra: 54.9 FPS average

At 2560x1440:

• Low: 133.4 FPS average
• Medium: 102.4 FPS average
• High: 76.5 FPS average
• Ultra: 75.8 FPS average

At 1920x1080:

• Low: 165.2 FPS average
• Medium: 128.9 FPS average
• High: 98.6 FPS average
• Ultra: 94.2 FPS average

The pattern across all resolutions is consistent: increasing settings from Low to Ultra reduces FPS by roughly 40-50%. The largest absolute drop occurs at 4K, where Ultra is 41.3 FPS lower than Low. At 1080p, the drop from Low to Ultra is 71 FPS, but the starting point is much higher.

The data also shows diminishing returns at higher settings. At 1440p, the difference between High (76.5 FPS) and Ultra (75.8 FPS) is negligible at 0.7 FPS, suggesting that Ultra is essentially free at this resolution. At 4K, the gap between High and Ultra is 3 FPS, which is also small. The biggest jumps are from Low to Medium (23.4 FPS at 4K, 31 FPS at 1440p, 36.3 FPS at 1080p), indicating that Medium is a significant step up in visual quality for a moderate performance cost.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Medium, with an average of 72.8 FPS. This provides a good balance between visual quality and performance, as High and Ultra both fall below the 60 FPS threshold.

At 2560x1440, Ultra is the best setting, averaging 75.8 FPS. This is the highest quality preset available, and it still leaves 15.8 FPS of headroom above the 60 FPS line. There is no need to reduce settings at this resolution, as even the most demanding option is playable.

At 1920x1080, Ultra is also the best setting, with an average of 94.2 FPS. This provides over 34 FPS of headroom, making it an excellent choice for users with high-refresh-rate monitors. The GPU has plenty of capacity at this resolution, so there is no reason to compromise on visual fidelity.

For users who prioritize higher frame rates over visual quality, the data shows that dropping to Low at 1440p yields 133.4 FPS, and at 1080p Low reaches 165.2 FPS. However, the Ultra settings at these resolutions are already well above 60 FPS, so the trade-off is only necessary for users targeting 144Hz or higher refresh rates. The recommended settings based on the playable threshold of 60 FPS are: 4K Medium (72.8 FPS), 1440p Ultra (75.8 FPS), and 1080p Ultra (94.2 FPS).
