Microsoft Flight Simulator

The measured data for Microsoft Flight Simulator with the Intel Core i5-14600K and NVIDIA GeForce RTX 2060 shows a configuration that is heavily balanced toward CPU capability, with the GPU acting as the primary bottleneck in most scenarios. The combination of a high-end 14-core processor and a mid-range 6 GB graphics card produces a predictable pattern: frame rates scale with resolution and settings, but the ceiling is set by the graphics card's memory and compute limits. This analysis walks through the optimal settings, the division of labor between the processor and graphics card, the combo's standing among tested systems, and the exact frame rates measured.

Settings Recommendations

Across all three tested resolutions, the Medium preset offers the best balance between visual fidelity and playable frame rates. At 1920x1080, Medium delivers an average of 71 FPS, which is 17 FPS higher than High (54 FPS) and 20 FPS higher than Ultra (51 FPS). The gap between Medium and Low at 1080p is 21 FPS (71 vs. 92), but the visual cost of dropping to Low is substantial for a flight simulator where terrain detail and cockpit readability matter. Medium also provides the only complete min/max data in the entire dataset, with a minimum of 61 FPS and maximum of 82 FPS at 1080p, indicating stable frame pacing without severe dips.

Moving to 2560x1440, Medium remains the strongest choice, producing 58 FPS on average. This is 15 FPS ahead of High (43 FPS) and 17 FPS ahead of Ultra (41 FPS). The min/max range at 1440p Medium is 49 to 66 FPS, which shows a wider variance than at 1080p but still stays above the 30 FPS threshold for acceptable simulation gameplay. Low at 1440p reaches 74 FPS, but again, the fidelity trade-off is steep. At 3840x2160, Medium drops to 42 FPS, which is playable but marginal; the measured min of 36 FPS and max of 49 FPS show that the system is approaching its limits. High at 4K manages only 32 FPS, and Ultra falls to 30 FPS, both of which are below the smoothness most pilots would accept.

The data suggests that for a consistent experience, Medium is the default recommendation at any resolution. If the user prioritizes frame rate over visuals, Low provides a significant boost—55 FPS at 4K, 74 FPS at 1440p, and 92 FPS at 1080p—but the jump from Low to Medium at 1080p costs only 21 FPS while restoring a meaningful amount of scene detail. Ultra is never worth the penalty, as it delivers only 51 FPS at 1080p and 30 FPS at 4K, essentially matching the performance of High at 4K while demanding more from the hardware. The sweet spot is Medium, and the data shows it is the only preset that yields both playable averages and documented minimums across all resolutions.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor based on Raptor Lake architecture, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. Its benchmark scores are exceptionally strong for a mid-range desktop chip: a Cinebench R23 multi-core score of 24491 and a single-core score of 2064, with a Geekbench multi-core score of 16673 and single-core score of 2491. In PassMark testing, it achieves a multithread score of 38682 and a single-thread score of 4270, placing it in the 90th percentile of all CPUs. This processor is clearly not the limiting factor in this game combination.

Flight simulators are known for being CPU-intensive, particularly for physics calculations and scenery generation, but the measured FPS data shows that the i5-14600K has ample headroom. When comparing the frame rates across resolutions, the drop from 1080p to 4K at the same settings is significant—for example, Medium goes from 71 FPS at 1080p to 42 FPS at 4K—which indicates the GPU is the bottleneck, not the CPU. The processor's 24 MB of shared L3 cache and dual-channel memory support (both DDR4 and DDR5) provide the kind of bandwidth that flight simulators need for streaming terrain data.

The nearest rivals in the CPU benchmark database are the Intel Xeon Gold 5318H (deltaPct -0.2), AMD EPYC 4345P (deltaPct +0.3), Intel Core Ultra 5 245HX (deltaPct +0.7), and Intel Core Ultra 5 245 (deltaPct -0.8). These deltas are all within one percent, meaning the i5-14600K sits in a tightly contested performance band. The fact that the CPU's average benchmark score of 48618 is nearly identical to these rivals suggests that in this game, the processor's contribution to FPS is effectively saturated—no realistic CPU upgrade would change the measured results because the GPU is already holding the system back. The CPU's 125 W TDP and active production status indicate it is a current-generation part, but its role here is to feed the GPU without becoming a constraint.

GPU Role

The NVIDIA GeForce RTX 2060 is a Turing-architecture card with 6 GB of GDDR6 memory on a 192-bit bus, yielding 336.0 GB/s of bandwidth. Its base clock is 1365 MHz with a boost of 1680 MHz, and memory runs at 1750 MHz (14 Gbps effective). The card has 1920 shading units, 120 TMUs, and 48 ROPs, with 30 RT cores and 240 tensor cores. Its FP32 performance is 6.451 TFLOPS, and it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The GPU's PassMark G3D score is 14111, placing it in the 58th percentile of all GPUs, with an average benchmark score of 15290.

The RTX 2060's nearest rivals in the GPU database are the NVIDIA GeForce GTX 580 (deltaPct 0), AMD Radeon 680M (deltaPct +0.1), NVIDIA GeForce RTX 3050 OEM (deltaPct +0.6), and AMD Radeon RX 7600 (deltaPct +0.8). These deltas are all under one percent, showing that the RTX 2060 is at the very edge of a performance tier. This positioning is critical for understanding the measured FPS: the card is just barely competitive with modern integrated graphics and entry-level discrete cards, which explains why it struggles at higher resolutions.

The 6 GB VRAM is a clear constraint in Microsoft Flight Simulator. At 4K Ultra, the card produces 30 FPS, which is the same as 4K High (32 FPS) within a rounding error, suggesting the GPU is hitting a memory or compute wall rather than scaling with settings. The jump from Low to Medium at 4K costs 13 FPS (55 to 42), while the jump from Medium to High costs 10 FPS (42 to 32), and High to Ultra costs only 2 FPS (32 to 30). This compression at the top end is typical of a GPU that has run out of memory bandwidth or capacity. The same pattern appears at 1440p: Low is 74 FPS, Medium is 58 FPS, High is 43 FPS, and Ultra is 41 FPS, with the gap between High and Ultra shrinking to just 2 FPS. The GPU is the dominant limiting component in this combo.

How This Combo Ranks

The combination of the Core i5-14600K and RTX 2060 ranks 2912 out of 3714 tested combos in Microsoft Flight Simulator, placing it in the bottom 22nd percentile of all configurations. This ranking reflects the GPU's modest standing rather than the CPU's strength. The i5-14600K is in the 90th percentile of CPUs, but the RTX 2060 sits in the 58th percentile of GPUs, and the combo's overall rank is dragged down by the graphics card's performance ceiling. The data shows that this is a pairing where the processor is overqualified for the workload, and the GPU is the clear weak link.

Among all combos tested, this rank means that roughly 2911 other configurations deliver higher average FPS in this game. The implication is that users with this combo are getting performance that is closer to entry-level systems than to high-end flight sim rigs. The rank is a composite measure, and given the CPU's strength, the only way to improve this ranking would be to pair the i5-14600K with a more powerful GPU. The measured FPS data supports this: at 1080p Medium, the combo achieves 71 FPS, which is respectable, but at 4K Ultra, it falls to 30 FPS, which is at the edge of playability. The combo's rank of 2912 out of 3714 is a direct consequence of the GPU's 6 GB memory and its position in the 58th percentile of all GPUs. The CPU is not the constraint, and the data shows that any performance headroom in this system is entirely unused.

Resolution Scaling

The FPS drops from 1080p to 4K are steep and consistent across all settings, revealing the GPU as the limiting component. At Medium settings, the average FPS falls from 71 at 1080p to 58 at 1440p (a drop of 13 FPS, or 18%) and then to 42 at 4K (a further drop of 16 FPS, or 28%). At High settings, the progression is 54 FPS at 1080p, 43 at 1440p, and 32 at 4K—a cumulative decline of 22 FPS from 1080p to 4K, or about 41%. Low settings show the largest absolute drop: 92 FPS at 1080p, 74 at 1440p, and 55 at 4K, a total decline of 37 FPS. Ultra settings start at 51 FPS at 1080p and end at 30 FPS at 4K, a drop of 21 FPS.

These scaling patterns indicate that the RTX 2060 is bandwidth-limited. The 336.0 GB/s memory bandwidth is insufficient for the pixel throughput required at 4K, and the 6 GB VRAM capacity is also likely exceeded at higher resolutions and settings. The fact that the FPS drop from 1440p to 4K is larger than the drop from 1080p to 1440p at Medium (16 FPS vs. 13 FPS) suggests that the card is hitting a hard memory limit at 4K, not just a compute limit. If the CPU were the bottleneck, the FPS would stay relatively flat across resolutions, but the data shows a consistent downward slope, confirming that the GPU is the primary constraint. The CPU's high single-thread score of 2064 in Cinebench R23 and 4270 in PassMark means it can feed frames quickly, but the GPU cannot render them fast enough as resolution increases.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce an average of 92 FPS. Medium settings yield 71 FPS with a minimum of 61 FPS and a maximum of 82 FPS. High settings average 54 FPS. Ultra settings average 51 FPS. The spread from Low to Ultra is 41 FPS, showing that the GPU has some headroom at this resolution but is still limited by its memory and compute.

At 2560x1440, the averages are: Low 74 FPS, Medium 58 FPS (min 49, max 66), High 43 FPS, and Ultra 41 FPS. The gap between Low and Medium is 16 FPS, while the gap between High and Ultra is only 2 FPS, indicating that the GPU is starting to saturate at the higher preset levels. The minimum of 49 FPS at Medium is still playable, but the variance is wider than at 1080p.

At 3840x2160, the performance drops significantly. Low settings average 55 FPS. Medium settings average 42 FPS with a minimum of 36 FPS and a maximum of 49 FPS. High settings average 32 FPS. Ultra settings average 30 FPS. The difference between High and Ultra at 4K is just 2 FPS, while the difference between Low and Medium is 13 FPS. This compression at the top end is a clear sign that the GPU is fully utilized and cannot benefit from additional settings increases. The minimum of 36 FPS at 4K Medium is the lowest measured value in the entire dataset, and it is only barely above the threshold for smooth simulation gameplay.
