Microsoft Flight Simulator

The AMD Ryzen 7 3700X paired with the AMD Radeon RX 6600 delivers a playable but demanding experience in Microsoft Flight Simulator, with performance heavily dictated by resolution and preset. The data shows this combination struggles to maintain high refresh rates at 4K Ultra, but offers a solid 60+ FPS experience at 1080p with lower settings, placing it in the 79th percentile of all tested combos.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals a GPU-bound scenario at higher resolutions. At Low settings, the average frame rate falls from 92.7 FPS at 1920x1080 to 71.6 FPS at 2560x1440, a 22.8% reduction, and then further to 56.7 FPS at 3840x2160, a 20.8% reduction from 1440p. This steep decline indicates that the RX 6600's rendering capabilities are the primary limiting factor as pixel count increases.

At High settings, the scaling is even more pronounced. The average FPS drops from 56.8 at 1080p to 45.6 at 1440p and finally to 32.3 at 4K. The 4K High result is less than 60% of the 1080p High figure, demonstrating that the GPU's 8 GB frame buffer and 224.0 GB/s memory bandwidth are insufficient for the highest resolutions with demanding presets. The game becomes increasingly dependent on the GPU's compute throughput, which is rated at 8.928 TFLOPS FP32.

The gap between Low and Ultra settings widens with resolution. At 1080p, Ultra is 42.5% slower than Low (53.3 vs 92.7 FPS). At 4K, Ultra is 42.2% slower than Low (32.8 vs 56.7 FPS). This consistency suggests that while the GPU is the bottleneck at 4K, the CPU still contributes meaningfully to the overall frame time at lower resolutions, preventing a disproportionate collapse in performance.

GPU Role

The Radeon RX 6600's specifications directly explain its performance envelope in this simulator. With a boost clock of 2491 MHz and a game clock of 2044 MHz, the GPU has a solid frequency headroom, yet its 128-bit memory bus and 8 GB GDDR6 memory limit its ability to handle large texture sets at high resolutions. The 224.0 GB/s bandwidth is a modest figure for a game known for streaming vast scenery data.

The GPU's 64 ROPs and 112 TMUs are responsible for the pixel and texture fill rates, which are 159.4 GPixel/s and 279.0 GTexel/s respectively. These figures correlate with the measured FPS: the 4K High average of 32.3 FPS suggests that the GPU is working near its fill-rate limits. The 1792 shading units, delivering 8.928 TFLOPS FP32, are sufficient for 1080p Medium (73.9 FPS) but are overwhelmed by the 4K Ultra workload (32.8 FPS).

The VRAM capacity is a critical factor. At 4K with Ultra settings, the game's demand for memory likely exceeds the 8 GB capacity, leading to texture paging and reduced frame rates. The data shows a minimal difference between High and Ultra at 4K (32.3 vs 32.8 FPS), which indicates that the GPU is not merely compute-limited but also bandwidth and capacity-limited. The RX 6600's 3DMark Steel Nomad score of 1492 and Passmark G3D score of 15096 place it in the 69th percentile of all GPUs, confirming its mid-range positioning.

FAQ

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

A: 1920x1080 is the most viable resolution, as even at Medium settings it achieves 73.9 FPS, while 2560x1440 requires Low settings to exceed 60 FPS (71.6 FPS).

Q: How does the RX 6600's performance compare to its nearest rival, the RTX 3060 Ti?

A: The average benchmark score for the RX 6600 is 25235, which is 0.5% higher than the RTX 3060 Ti's score of 25120, indicating near-identical overall performance.

Q: Is the Ryzen 7 3700X a bottleneck for the RX 6600 in this game?

A: At 4K Ultra, the GPU is the clear bottleneck, as the CPU's 8 cores and 16 threads are sufficient for the workload; however, at 1080p Low (92.7 FPS), the CPU's single-thread performance (Cinebench R23 single-core score of 2694) may become more relevant.

Q: What is the FPS difference between High and Ultra settings at 1440p?

A: The average FPS drops from 45.6 on High to 39.3 on Ultra at 2560x1440, a difference of 6.3 FPS, making Ultra a heavy cost for minimal visual gain.

Q: Does the combo rank highly among all tested configurations?

A: It ranks 1427 out of 1795 total combos, placing it in the 79th percentile, which is a solid mid-tier ranking for this demanding simulator.

Q: How much slower is 4K Ultra compared to 1080p Low?

A: 4K Ultra averages 32.8 FPS, which is 64.6% lower than the 92.7 FPS seen at 1080p Low, illustrating the severe performance penalty at the highest settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce 92.7 FPS, Medium drops to 73.9 FPS, High to 56.8 FPS, and Ultra to 53.3 FPS. The jump from Medium to High costs 17.1 FPS, while the jump from High to Ultra costs only 3.5 FPS, suggesting diminishing returns at the top end.

Moving to 2560x1440, the figures are 71.6 FPS on Low, 59.2 FPS on Medium, 45.6 FPS on High, and 39.3 FPS on Ultra. The 1440p Medium result remains playable, but High and Ultra fall below the 60 FPS threshold, marking a clear transition point where the GPU starts to struggle.

At 3840x2160, performance is limited. Low settings yield 56.7 FPS, Medium drops to 42.3 FPS, High to 32.3 FPS, and Ultra to 32.8 FPS. The negligible difference between High and Ultra at 4K (0.5 FPS) suggests that both presets are constrained by the same hardware limits, likely VRAM capacity and memory bandwidth, rather than compute shader load.

Settings Recommendations

For a smooth experience, the Low preset at 2560x1440 is the optimal choice, offering 71.6 FPS. This provides a 60+ FPS experience while maintaining a higher resolution than 1080p. At 1080p, Medium (73.9 FPS) is the best balance, as it is only 20.3% slower than Low but delivers significantly better visual fidelity. High at 1080p (56.8 FPS) is acceptable for players prioritizing visuals over frame rate, but the 17.1 FPS drop from Medium is substantial.

At 4K, the Low preset is the only option for playability, with 56.7 FPS. Medium at 42.3 FPS is borderline, while High and Ultra (32.3 and 32.8 FPS) are too sluggish for smooth flight simulation. The data indicates that Ultra settings are not worth the performance cost at any resolution, as the average FPS gain from High to Ultra is minimal across all tested resolutions.

CPU Role

The Ryzen 7 3700X, with its 8 cores and 16 threads based on Zen 2 architecture, provides a robust foundation for this simulator. Its Cinebench R23 multi-core score of 19087 and single-core score of 2694 indicate strong overall processing power. The 32 MB L3 cache and 51.2 GB/s memory bandwidth are adequate for feeding the GPU at lower resolutions.

The CPU's percentile ranking of 85th among all CPUs, with an average benchmark score of 28631, places it just 0.1% behind the Intel Core i5-12600 and 0.1% ahead of the AMD Ryzen 5 5600XT. This suggests that in CPU-bound scenarios, the 3700X is competitive with modern mid-range parts. However, in this game, the measured FPS patterns show that the GPU becomes the bottleneck starting at 1440p Medium, meaning the CPU's 3.60 GHz base and 4.40 GHz boost clocks are sufficient to avoid major frame pacing issues.

The Passmark multi-thread score of 22458 and single-thread score of 2656 confirm that the CPU has ample headroom for the simulator's physics and AI calculations. At 1080p Low, where the GPU load is light, the CPU's performance becomes more critical, and the 92.7 FPS result shows it can keep up with the RX 6600's output.

How This Combo Ranks

In the database of 1795 tested combinations, this pairing of the Ryzen 7 3700X and RX 6600 achieves a rank of 1427. This places it in the 79th percentile, meaning it outperforms roughly 79% of all tested combos in Microsoft Flight Simulator. This ranking reflects the balanced nature of the components: the CPU is near the top of its class, while the GPU is mid-range, resulting in a system that is capable but not exceptional for this particular title.

The ranking is consistent with the measured FPS data. At 1080p Low, the combo achieves 92.7 FPS, which is competitive with many higher-end pairings. At 4K Ultra, the 32.8 FPS result is below the average for top-tier systems, but it remains playable for a simulator that prioritizes fidelity over frame rate. The gap between the combo's rank and the top performers is primarily due to the GPU's limitations at high resolutions, as the CPU's performance is within 0.2% of its nearest rivals, including the AMD EPYC 7203P.
