Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title, and the combination of the AMD Ryzen 5 7500X3D and NVIDIA GeForce RTX 4080 produces a wide spread of performance depending on how you configure it. The measured data shows a system that can handle high refresh rates at 1440p but requires careful settings management to maintain smooth frame rates at 4K. This analysis breaks down the measured FPS across resolutions and presets, explains the role of the GPU and CPU, and offers practical settings advice based strictly on the provided benchmark results.

Resolution Scaling

The performance drop from 1080p to 4K is significant and clearly indicates a GPU-bound scenario at higher resolutions. At Low settings, the average frame rate falls from 185 FPS at 1920x1080 to 170 FPS at 2560x1440, a reduction of 15 FPS, and then to 125 FPS at 3840x2160, a further drop of 45 FPS. This scaling pattern shows that while the RTX 4080 is powerful, the sheer pixel count of 4K demands more from the graphics card.

The trend is consistent across all presets. With High settings, the average FPS goes from 123 at 1080p to 99 at 1440p, and finally to 73 at 4K. The Ultra preset follows a similar path, dropping from 117 at 1080p to 95 at 1440p and 70 at 4K. The Medium preset shows a 132 FPS average at 1440p and 97 at 4K, with the 1080p result at 164 FPS. These numbers confirm that moving from 1440p to 4K carries a substantial performance penalty, roughly a 25-30% reduction in average frame rate depending on the preset.

The fact that the 1080p to 1440p drop is smaller than the 1440p to 4K drop suggests that at lower resolutions, the CPU's performance is more influential. At 4K, the GPU becomes the primary limiting factor. For a flight simulator, where smooth visuals are critical for immersion, the data suggests that 4K is only viable with settings tuned to Medium or lower, while 1440p offers a much better balance for maintaining high frame rates with higher visual quality.

GPU Role

The NVIDIA GeForce RTX 4080 is the driving force behind this system's graphics performance. It comes with 16 GB of GDDR6X memory on a 256-bit bus, providing a memory bandwidth of 716.8 GB/s. This large memory pool is beneficial for a game like Microsoft Flight Simulator, which often handles large textures and scenery data. The GPU's boost clock is rated at 2505 MHz, and its benchmark scores place it in the 86th percentile of all GPUs.

In terms of raw compute, the RTX 4080's 3DMark Steel Nomad DX12 score is 6567, and its Passmark G3D score is 34457. The data shows it performs nearly identically to its direct rival, the RTX 4080 SUPER, with a deltaPct of 0.1. It is also 1.1% ahead of the AMD Radeon Pro W5700X and 2.6% ahead of the AMD Radeon RX 6750 GRE 12 GB. The measured FPS results indicate that the GPU is capable of producing very high frame rates at 1080p and 1440p, but its performance at 4K with higher presets is what limits the overall experience.

The GPU's role is clear: it provides the headroom for high refresh rate gaming at 1440p and enables 4K gaming at medium settings. The 16 GB of VRAM is a strong asset, but the data does not show a scenario where VRAM capacity alone becomes the bottleneck. Instead, the GPU's raw processing power is the deciding factor at 4K.

Settings Recommendations

Based on the measured rows, the best experience for most users will be found at 2560x1440 with High or Ultra settings. The data shows a 99 FPS average for High and a 95 FPS average for Ultra at this resolution. The difference of only 4 FPS between these two presets suggests that the visual gains from Ultra are relatively cheap at 1440p, making it a worthwhile option for those with a high refresh rate monitor.

For 4K users, the recommendation is to use Medium settings. The 3840x2160 Medium preset yields a 97 FPS average with a minimum of 83 FPS and a maximum of 112 FPS. This is the only 4K preset that remains comfortably above a 60 FPS threshold. In contrast, the High and Ultra presets at 4K dip below 73 FPS, which may not be ideal for a smooth experience. The 4K Low preset runs at 125 FPS, but the visual compromise is likely too significant for a simulator.

At 1080p, the system is overkill for most presets. The Low preset hits 185 FPS, while Medium, High, and Ultra all remain above 117 FPS. This resolution is best used with Ultra settings to maximize visual fidelity without worrying about frame rate. The data indicates that High at 1080p is a balanced choice, but Ultra provides a larger performance cost (117 FPS vs 123 FPS) for what is likely a marginal visual improvement.

Measured FPS Breakdown

This section details the exact measured average frame rates for each resolution and settings combination.

At 1920x1080, the results are as follows:

• Low: 185 FPS average
• Medium: 164 FPS average (minimum 139 FPS, maximum 188 FPS)
• High: 123 FPS average
• Ultra: 117 FPS average

At 2560x1440, the results are:

• Low: 170 FPS average
• Medium: 132 FPS average (minimum 112 FPS, maximum 152 FPS)
• High: 99 FPS average
• Ultra: 95 FPS average

At 3840x2160, the results are:

• Low: 125 FPS average
• Medium: 97 FPS average (minimum 83 FPS, maximum 112 FPS)
• High: 73 FPS average
• Ultra: 70 FPS average

The data shows a clear hierarchy: lower resolutions and lower settings produce higher frame rates. The Medium preset is the only one with min/max data, showing a consistent frame pacing at 1440p and 4K. The gap between Low and Medium is smaller than the gap between Medium and High, suggesting that the High preset introduces a significant graphical load. The Ultra preset offers only a slight reduction in performance compared to High, indicating it is not as demanding a step up.

FAQ

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

A: The data shows 2560x1440 is the sweet spot. High and Ultra presets both maintain an average above 95 FPS, offering a strong balance between visual quality and smoothness.

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

A: Yes, but with limitations. The measured 4K Medium preset averages 97 FPS with a minimum of 83 FPS, which is playable. However, the 4K High and Ultra presets drop to 73 and 70 FPS averages respectively, which may not be smooth enough for all users.

Q: How much of a performance hit is there from 1080p to 4K?

A: The performance drop is substantial. At Low settings, the average FPS falls from 185 at 1080p to 125 at 4K. At High settings, it falls from 123 to 73 FPS. This represents a roughly 30-40% reduction in frame rate when moving to 4K.

Q: Which settings preset offers the biggest performance jump?

A: The data indicates a large gap between Low and Medium. For example, at 1440p, the Low preset hits 170 FPS, while Medium drops to 132 FPS. The jump from Medium to High is smaller (132 to 99 FPS), and the jump from High to Ultra is very small (99 to 95 FPS).

Q: Is the RTX 4080's 16 GB of VRAM sufficient?

A: Based on the measured results, the data does not indicate a VRAM limitation. The performance scaling is consistent with a GPU compute bottleneck, not a memory capacity issue. The 16 GB is more than enough for the tested presets.

Q: How does this GPU compare to its closest rival?

A: The RTX 4080 is essentially tied with the RTX 4080 SUPER, showing a deltaPct of 0.1 in average benchmark score. It is also 1.1% faster than the AMD Radeon Pro W5700X and 2.6% faster than the AMD Radeon RX 6750 GRE 12 GB.

CPU Role

The AMD Ryzen 5 7500X3D is a 6-core, 12-thread processor based on the Zen 4 architecture. It has a base clock of 4.00 GHz and a boost clock of 4.50 GHz, with a 96 MB shared L3 cache. This processor is part of the 7000 series and sits in the 89th percentile of all CPUs based on its average benchmark score of 44573. Its Passmark multi-thread score is 25047, and its single-thread score is 3494.

The CPU's role in this game is to feed the GPU with draw calls and simulation data. The benchmark results show that it performs nearly identically to its nearest rivals, including the Intel Core Ultra X9 388H (deltaPct 0.2) and the Intel Core i9-13950HX (deltaPct 0.5). It is also 0.7% faster than the Intel Core i5-14600. The data suggests that this CPU provides ample performance to avoid being a significant bottleneck at lower resolutions.

The evidence for this is the frame rate scaling. At 1080p, the system achieves very high frame rates (up to 185 FPS), which indicates the CPU can handle the workload. However, as the resolution increases, the frame rate drops, which is the classic sign of the GPU becoming the limiting factor. The 6-core configuration with a high L3 cache is well-suited for this kind of simulation, where large amounts of data need to be processed quickly. The CPU's performance is adequate to keep up with the RTX 4080, ensuring that the GPU's potential is fully utilized, especially at 1440p and 4K.
