Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding workloads in PC gaming, and the pairing of the AMD Ryzen 7 3700X with the AMD Radeon RX 7600 produces a revealing set of benchmark data. This combination, ranked 1247 out of 1795 tested combos in this title, shows a system that is clearly capable of playable flight, but one where the balance between CPU and GPU shifts dramatically depending on the resolution and quality settings selected. The measured frames per second across three resolutions and four presets tell a story of a GPU that leads at lower loads and a CPU that anchors the experience at the highest visual fidelity.

Resolution Scaling

The most striking trend in the data is how performance degrades as resolution increases from 1920x1080 to 3840x2160. At the Low preset, the system delivers 103.2 FPS at 1080p, which drops to 80.9 FPS at 1440p, and finally to 59.7 FPS at 4K. This represents a 42% reduction in frame rate from 1080p to 4K at Low settings, which is a substantial hit but still leaves the experience comfortably playable. The scaling suggests that at Low settings, the GPU is the primary limiting factor, as the frame rate drops proportionally with the increase in pixel count.

Moving to the High preset reveals a different bottleneck dynamic. The system produces 57.1 FPS at 1080p, 48.7 FPS at 1440p, and 34.8 FPS at 4K. The drop from 1080p to 4K here is 39%, which is slightly less severe than at Low settings. This indicates that as the visual load increases, the CPU begins to play a more significant role in limiting performance, preventing the frame rate from scaling purely with GPU load. The Ultra preset shows the tightest scaling, with 55.6 FPS at 1080p falling to 45.4 FPS at 1440p and 33.4 FPS at 4K, a 40% total drop, suggesting that the CPU is heavily engaged at all resolutions when the highest quality assets are loaded.

The data implies that for this combination, 1440p is the sweet spot where the GPU and CPU workloads are most balanced. At 1080p, the RX 7600 is often underutilized, as the Ryzen 7 3700X cannot feed it enough frames to reach higher numbers. At 4K, the GPU becomes the clear bottleneck, especially at Medium and High settings, where the frame rates fall below the 60 FPS threshold that many flight simulator enthusiasts prefer.

Settings Recommendations

Examining the measured rows, the Low preset at 1080p delivers the highest frame rate at 103.2 FPS, but this likely sacrifices too much visual detail for a game that is about immersion. The Medium preset at 1080p provides 78.2 FPS, which is a significant improvement over Low while still maintaining a smooth experience. For users with 1080p displays, Medium appears to be the optimal balance, offering a 36% performance uplift over High settings at the same resolution, which only manages 57.1 FPS.

At 1440p, the Medium preset produces 62.9 FPS, which is just above the 60 FPS target, while High drops to 48.7 FPS. The data suggests that 1440p Medium is the highest quality setting that maintains a consistently smooth frame rate for this hardware. At 4K, the situation becomes more constrained; the Low preset achieves 59.7 FPS, which is barely playable, while Medium drops to 45 FPS and High falls to 34.8 FPS. For 4K users, the Low preset is the only option that approaches playability, and even then, it hovers at the edge of the 60 FPS ideal.

The Ultra preset is consistently the worst performer at every resolution, with 55.6 FPS at 1080p, 45.4 FPS at 1440p, and 33.4 FPS at 4K. The performance gap between Ultra and High is relatively small, with only a 3% difference at 1080p, which suggests that the Ultra preset imposes a heavy CPU cost that does not translate to proportional visual gains on this hardware. The recommendation is clear: for the best experience, users should prioritize Medium settings at 1080p or 1440p, accepting a frame rate in the 60-78 FPS range rather than chasing the visual extremes of Ultra.

How This Combo Ranks

Within the database of tested combinations, this specific pairing of the Ryzen 7 3700X and RX 7600 ranks 1247 out of 1795 combos in Microsoft Flight Simulator. This places the system in the lower half of all tested configurations, which is notable given that both components are relatively modern. The ranking suggests that while each part is individually capable, the combination does not synergize exceptionally well for this particular title, which is known for its heavy single-threaded CPU demands and large texture loads.

The CPU itself sits in the 85th percentile versus all CPUs in the database, indicating that the Ryzen 7 3700X is a strong processor on its own. Its nearest rivals include the Intel Core i5-12600, which has an average score just 0.1% higher, and the AMD Ryzen 5 5600XT, which is 0.1% lower. This shows that the 3700X is competitive with newer mid-range parts in general compute tasks. However, the GPU ranks in only the 63rd percentile versus all GPUs, which is a more modest position. Its nearest rivals include the RX 7600 XT at 0.6% higher and the RX 460 at 0.8% lower, showing a wide spread of performance in its immediate peer group.

The gap between the CPU's high percentile and the GPU's lower percentile explains the combo's mid-pack ranking. The data indicates that the GPU is the weaker link in this pairing, and the overall ranking of 1247 out of 1795 reflects a system that is held back by its graphics card in a game that scales heavily with GPU memory bandwidth and processing power. The combo ranking is not a judgment of quality but a measure of how this specific hardware pairing performs in this specific workload.

Measured FPS Breakdown

At 1920x1080, the system delivers a full range of results: 103.2 FPS on Low, 78.2 FPS on Medium, 57.1 FPS on High, and 55.6 FPS on Ultra. The step from Low to Medium costs 24% of the frame rate, while the step from Medium to High costs 27% more, and High to Ultra only costs 3%. This pattern shows diminishing returns at the highest settings, where the CPU becomes a limiting factor.

At 2560x1440, the numbers are 80.9 FPS on Low, 62.9 FPS on Medium, 48.7 FPS on High, and 45.4 FPS on Ultra. The drop from Low to Medium is 22%, Medium to High is 23%, and High to Ultra is 7%. The scaling is more consistent at 1440p, suggesting a better balance between CPU and GPU load across the settings range.

At 3840x2160, the results are 59.7 FPS on Low, 45 FPS on Medium, 34.8 FPS on High, and 33.4 FPS on Ultra. The Low to Medium drop is 25%, Medium to High is 23%, and High to Ultra is only 4%. At 4K, the GPU is clearly the dominant bottleneck, as the frame rates cluster tightly at the low end, with the CPU having little influence on the outcome.

The data shows that the Ultra preset offers virtually no benefit over High at any resolution, with a maximum difference of 2.9 FPS at 1440p. Conversely, the Low preset always provides a massive boost, with the largest gain being 47.6 FPS at 1080p over Ultra. The Medium preset is the most balanced option, offering a 36% improvement over High at 1080p while only sacrificing a modest amount of visual quality.

CPU Role

The AMD Ryzen 7 3700X is an 8-core, 16-thread processor based on the Zen 2 architecture, built on a 7 nm process. It has a base clock of 3.60 GHz and a boost clock of 4.40 GHz, with 32 MB of L3 cache. The CPU sits in the 85th percentile versus all CPUs, with an average benchmark score of 28631, placing it just 0.1% behind the Intel Core i5-12600 and 0.1% ahead of the AMD Ryzen 5 5600XT.

In Microsoft Flight Simulator, the CPU's role is evident in the scaling behavior at 1080p. The frame rates at High and Ultra settings are nearly identical, at 57.1 and 55.6 FPS respectively, which suggests that the processor is maxed out and cannot take advantage of the GPU's additional headroom. The CPU's strong multi-threaded performance, evidenced by a Cinebench R23 multi-core score of 19087, helps with the simulation's complex flight model and AI traffic, but the single-threaded performance, with a Geekbench single-core score of 1672, appears to be the limiting factor.

The 3700X's performance in this game is consistent with its near-rivals. The 0.1% delta with the i5-12600 and the Ryzen 5 5600XT shows that the 3700X is not a bottleneck unique to this game but rather a typical mid-range performer from its generation. The data implies that upgrading to a newer CPU with higher single-thread performance could improve frame rates at 1080p High settings, but the gains would be modest given the GPU's limitations at higher resolutions.

GPU Role

The AMD Radeon RX 7600 is based on the RDNA 3.0 architecture and features 8 GB of GDDR6 memory on a 128-bit bus, providing 288.0 GB/s of bandwidth. It has a base clock of 1720 MHz and a boost clock of 2655 MHz, with 2048 shading units and 32 ray tracing cores. The GPU ranks in the 63rd percentile versus all GPUs, with an average benchmark score of 20258, placing it 0.6% behind the RX 7600 XT and 1.3% behind the NVIDIA GeForce RTX 3070 Mobile.

The GPU's role in this pairing becomes clear at 4K resolution, where it is the dominant bottleneck. At 4K Ultra, the card produces 33.4 FPS, and at High, 34.8 FPS, showing that the GPU cannot handle the pixel load regardless of CPU performance. The 8 GB VRAM capacity is likely a constraint at 4K with high-quality textures, as the card's 288.0 GB/s bandwidth struggles to feed the large texture sets used by the game.

At 1080p, the GPU has more headroom, but the data shows it is often waiting on the CPU. The RX 7600's DirectX 12 score of 58 and 3DMark Steel Nomad score of 2310 indicate solid raw performance, but the card's 63rd percentile ranking suggests it is not a top-tier part. The nearest rival, the RX 7600 XT, is only 0.6% faster, which implies that the standard 7600 is well-positioned within its own family, but the modest VRAM and memory bandwidth limit its effectiveness in a simulation game that heavily utilizes large textures and draw distances.
