Microsoft Flight Simulator

Resolution Scaling

The measured frame rates for Microsoft Flight Simulator with the Intel Core i7-14700K and AMD Radeon RX 580 show a clear and steep performance cliff as resolution increases. At 1080p Low, the combo delivers 54 FPS, but moving to 1440p Low drops that to 43 FPS, and 4K Low further reduces it to 32 FPS. This pattern—a loss of roughly 20% from 1080p to 1440p and another 26% from 1440p to 4K—indicates that the GPU is the dominant limiting component across all tested configurations.

The scaling behavior becomes more pronounced at higher settings. At Ultra, the frame rates are 30 FPS (1080p), 24 FPS (1440p), and 18 FPS (4K). That is a 20% drop from 1080p to 1440p, followed by a 25% drop to 4K. The consistency of these percentage losses—regardless of preset—suggests the RX 580's rendering throughput, not the CPU's processing power, is the bottleneck. The i7-14700K, with its 20 cores and 28 threads, is far more capable than what this workload demands, so the frame rate ceiling is set by the GPU's pixel and texture throughput.

Notably, the delta between Low and Ultra at each resolution is relatively narrow. At 1080p, the gap is 24 FPS (54 vs 30); at 1440p, it is 19 FPS (43 vs 24); at 4K, it is 14 FPS (32 vs 18). This compression of the settings range at higher resolutions is a classic sign of a GPU-bound scenario—when the GPU is already saturated, reducing graphical complexity yields diminishing returns because the core shading units are still the limiting factor. The data shows that even at Low settings, 4K remains unplayable for smooth flight simulation, while 1080p Low is the only configuration that approaches a playable threshold.

The RX 580's 8 GB of GDDR5 memory and 256-bit bus provide 256.0 GB/s of bandwidth, which is adequate for 1080p but strained at 1440p and 4K. The measured FPS at 4K Medium (25 FPS) versus 4K Low (32 FPS) shows that memory bandwidth and fill rate are the primary constraints, as the GPU's 42.88 GPixel/s pixel rate and 193.0 GTexel/s texture rate cannot keep up with the increased pixel count. For users targeting 4K, the data indicates this combo is not viable for any preset; for 1440p, only Low settings approach a borderline playable experience.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo is 1080p with Low settings, which yields 54 FPS average. This is the only configuration that exceeds the 30 FPS threshold, and it does so with a comfortable margin. The Medium preset at 1080p delivers 42 FPS, which is also playable but comes with a 22% performance penalty compared to Low. Given that Microsoft Flight Simulator is a simulation where smoothness and responsiveness are critical for situational awareness, the extra 12 FPS from Low settings is more valuable than the visual fidelity gains from Medium.

At 1440p, the data shows that Low settings (43 FPS) are the only viable option, while Medium (34 FPS) is borderline and High (25 FPS) and Ultra (24 FPS) fall below acceptable playability. Users with 1440p monitors should stick to Low to maintain a consistent frame rate, as the jump from Low to Medium costs 9 FPS—a 21% reduction—for marginal visual improvements. The 4K results are uniformly poor, with even Low settings at 32 FPS feeling sluggish for a flight simulator; no preset at this resolution is recommended.

For those who prioritize visual quality over frame rate, 1080p Medium at 42 FPS is the best compromise. It maintains a playable frame rate while providing a meaningful upgrade over Low. However, the data suggests that High (31 FPS) and Ultra (30 FPS) at 1080p are too close to the 30 FPS boundary, making them risky choices for scenarios with dense scenery or weather effects that could cause drops. The measured minimum FPS at 1080p Medium is 36 FPS, which indicates that even in heavier moments, the combo stays above 30 FPS, whereas High and Ultra have no min FPS data, suggesting less stability.

In summary, the recommendation hierarchy from the data is: 1080p Low (best performance), 1080p Medium (best balance), 1440p Low (acceptable for 1440p users), and nothing at 4K. The i7-14700K's CPU headroom is wasted at lower resolutions, but the RX 580's limits are the deciding factor.

FAQ

Q: What is the best resolution and preset for this CPU/GPU combo in Microsoft Flight Simulator?

A: The data shows 1080p Low at 54 FPS is the best-performing configuration. For a balance of visuals and performance, 1080p Medium at 42 FPS is recommended, as it stays above 30 FPS even at minimum measured frames (36 FPS).

Q: Can this combo handle 4K in Microsoft Flight Simulator?

A: No. The measured FPS at 4K ranges from 18 FPS (Ultra) to 32 FPS (Low). Even the lowest settings fail to provide a smooth experience, and all 4K presets are below the 30 FPS playability threshold.

Q: How does the combo perform at 1440p?

A: At 1440p, Low settings produce 43 FPS, which is playable. Medium drops to 34 FPS, which is borderline, while High (25 FPS) and Ultra (24 FPS) are not recommended.

Q: Is the Intel Core i7-14700K bottlenecking the GPU in this game?

A: No. Benchmark results indicate the opposite—the GPU is the limiting factor. The i7-14700K has a 94th percentile ranking among all CPUs, while the RX 580 sits at the 53rd percentile. The frame rate scaling with resolution confirms the GPU is the constraint.

Q: What is the difference between Low and Ultra settings at 1080p?

A: The measured difference is 24 FPS: 54 FPS on Low versus 30 FPS on Ultra. This 44% performance gap is substantial, but both settings are playable, with Low being the only one that provides significant headroom.

Q: How does this combo rank compared to all other tested combos?

A: It ranks 3376th out of 3714 tested combos, placing it in the bottom 10% of all configurations for this game.

How This Combo Ranks

The combo of Intel Core i7-14700K and AMD Radeon RX 580 ranks 3376th out of 3714 tested combos in Microsoft Flight Simulator. This places it in the bottom 9% of all configurations, which is a poor result for a pairing that includes a top-tier CPU. The i7-14700K alone ranks in the 94th percentile among all CPUs, with an average benchmark score of 69355, putting it roughly on par with the AMD EPYC 9115 (69288, +0.1% delta) and slightly ahead of the AMD Ryzen 9 7950X (69515, -0.2% delta). However, the GPU drags the overall ranking down dramatically.

The RX 580's 53rd percentile ranking among all GPUs, with an average benchmark score of 12928, places it near the NVIDIA GeForce RTX 3050 Ti Mobile (12940, -0.1% delta) and NVIDIA GeForce GTX 1660 SUPER (12986, -0.4% delta). This mid-range GPU performance is entirely mismatched with the i7-14700K's capabilities for a demanding simulation like Microsoft Flight Simulator. The data shows that the CPU is not the limiting factor—the GPU's 6.175 TFLOPS of FP32 performance and 193.0 GTexel/s texture rate are simply insufficient for this game's rendering demands.

The rank of 3376 out of 3714 indicates that 338 other tested combos perform worse, but the vast majority of systems—over 90%—deliver better frame rates in this game. For context, this ranking means the combo sits in the bottom decile, which is consistent with the measured FPS data showing that only 1080p Low achieves a comfortable frame rate. Users with this pairing should understand that the GPU is the bottleneck and that upgrading the graphics card would yield far more significant improvements than any CPU change.

GPU Role

The AMD Radeon RX 580 plays the decisive role in this combo's performance, and its specifications explain the measured results. The GPU features 8 GB of GDDR5 memory on a 256-bit bus, providing 256.0 GB/s of bandwidth. Its base clock is 1257 MHz with a boost clock of 1340 MHz, and memory runs at 2000 MHz (8 Gbps effective). These figures are modest by modern standards, and the GPU's 53rd percentile ranking among all GPUs reflects its mid-range position.

The Polaris 20 chip, built on a 14 nm process at GlobalFoundries, contains 5,700 million transistors on a 232 mm² die. It has 2304 shading units, 144 texture mapping units, and 32 ROPs. The pixel rate of 42.88 GPixel/s and texture rate of 193.0 GTexel/s are the key metrics for understanding the 4K performance collapse. At 4K, the GPU must fill over 8 million pixels per frame, and the data shows that even at Low settings, it can only manage 32 FPS—a pixel throughput of roughly 274 million pixels per second, which is close to the theoretical pixel rate limit when accounting for other overhead.

The 8 GB VRAM capacity is sufficient for 1080p and 1440p, but the bandwidth becomes a constraint at higher resolutions. The measured FPS at 4K Medium (25 FPS) versus 4K Low (32 FPS) shows that the GPU's memory subsystem cannot handle the increased data throughput required by medium textures at 4K. The GPU's DirectX 12 support (12_0) and Vulkan 1.3 API compatibility are adequate, but the underlying GCN 4.0 architecture is not optimized for the draw call heavy workloads of Microsoft Flight Simulator.

The RX 580's measured FPS data aligns with its benchmark scores: a Passmark G3D score of 8813 and a 3DMark Steel Nomad DX12 score of 1005. These scores place it in the same performance tier as the GTX 1660 SUPER and RTX 3050 Ti Mobile, both of which would likely produce similar frame rates in this game. The GPU's 6.175 TFLOPS FP32 compute is the fundamental limit, and the data shows that no amount of CPU power from the i7-14700K can compensate for this shortfall.

Measured FPS Breakdown

The complete measured FPS data for Microsoft Flight Simulator with the Intel Core i7-14700K and AMD Radeon RX 580 is as follows:

1080p (1920x1080):

• Low: 54 FPS average
• Medium: 42 FPS average (minimum 36 FPS, maximum 48 FPS)
• High: 31 FPS average
• Ultra: 30 FPS average

1440p (2560x1440):

• Low: 43 FPS average
• Medium: 34 FPS average (minimum 29 FPS, maximum 39 FPS)
• High: 25 FPS average
• Ultra: 24 FPS average

4K (3840x2160):

• Low: 32 FPS average
• Medium: 25 FPS average (minimum 21 FPS, maximum 29 FPS)
• High: 19 FPS average
• Ultra: 18 FPS average

The only configurations with measured minimum and maximum FPS are the Medium presets at each resolution. At 1080p Medium, the minimum of 36 FPS ensures that the frame rate never drops below a playable threshold, even in demanding scenes. At 1440p Medium, the minimum of 29 FPS dips below 30, indicating occasional stutter. At 4K Medium, the minimum of 21 FPS makes the experience consistently choppy.

The spread between Low and Ultra at each resolution narrows as resolution increases: 24 FPS at 1080p, 19 FPS at 1440p, and 14 FPS at 4K. This narrowing confirms the GPU-bound nature of the workload—at higher resolutions, the GPU's fill rate limits performance so severely that graphical settings have less impact. The jump from Low to Medium costs 12 FPS at 1080p, 9 FPS at 1440p, and 7 FPS at 4K, while the jump from Medium to High costs 11 FPS at 1080p, 9 FPS at 1440p, and 6 FPS at 4K.

From High to Ultra, the changes are minimal: 1 FPS at 1080p, 1 FPS at 1440p, and 1 FPS at 4K. This suggests that the Ultra preset adds visual features that are largely handled by CPU-side processing, which the i7-14700K can absorb without performance loss, but the GPU's rendering load remains the same. The data clearly shows that for this combo, the RX 580 is the sole determinant of frame rates, and users should optimize their settings around the GPU's capabilities rather than the CPU's substantial headroom.
