FAQ

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

A: The measured data shows that 1920x1080 is the only resolution where all four presets (Low, Medium, High, Ultra) achieve average FPS above 50. At 2560x1440, the Low preset averages 74 FPS and Medium averages 58 FPS, but High and Ultra drop to 43 and 41 FPS respectively. At 3840x2160, all presets fall below 55 FPS, with Ultra averaging just 31 FPS. Therefore, 1080p is the recommended resolution for consistent performance.

Q: How does the CPU's core and thread configuration affect performance in this game?

A: The Ryzen 9 9900X3D features 12 cores and 24 threads with a base clock of 4.40 GHz and a boost clock of 5.50 GHz. Its Cinebench R23 multicore score of 47737 and Geekbench multicore score of 22884 indicate strong multi-threaded performance, which is beneficial for flight simulation’s complex physics and scenery calculations. However, the game’s frame rates are ultimately constrained by the GPU, as evidenced by the significant FPS drops when increasing resolution.

Q: What is the limiting factor for this system at 4K resolution?

A: The GPU is the clear limiting factor. The RX 6600 has 8 GB of GDDR6 memory with a 128-bit bus and 224.0 GB/s bandwidth. At 3840x2160, the average FPS ranges from 31 on Ultra to 55 on Low, suggesting that the GPU’s memory bandwidth and compute capacity are insufficient for high-resolution rendering. The CPU’s performance, in contrast, does not degrade proportionally with resolution.

Q: How does the RX 6600 compare to its nearest rivals in synthetic benchmarks?

A: The RX 6600’s average benchmark score is 19036. Its nearest rival, the NVIDIA Quadro K6000, has an average score of 19030, a delta of 0%. The NVIDIA GeForce RTX 4050 Mobile scores 19049, which is 0.1% higher. The NVIDIA Tesla K20m is 0.3% higher at 19089, while the NVIDIA RTX 2000 Ada Generation lags 0.4% behind at 18954. This places the RX 6600 in a tight competitive band with these cards.

Q: Can the system handle Ultra settings at any resolution?

A: Yes, but only at 1080p where it achieves an average of 51 FPS. At 1440p, Ultra averages 41 FPS, and at 4K, it drops to 31 FPS. The game remains technically playable at 1440p Ultra, but the frame rates suggest a compromise in smoothness. For a better experience, Medium settings at 1440p (58 FPS) or High at 1080p (54 FPS) are more viable options.

Q: What do the minimum FPS figures indicate about frame pacing?

A: The data only provides minimum FPS for Medium settings at each resolution: 36 FPS at 4K, 49 FPS at 1440p, and 61 FPS at 1080p. These minimums are lower than the averages by 7 to 11 FPS, indicating some frame dropping during complex scenes. At 1080p Medium, the 61 FPS minimum ensures a mostly smooth experience, while at 4K the 36 FPS minimum could lead to noticeable stutter.

Settings Recommendations

For the best experience with this combo, the data suggests prioritizing resolution over ultra-quality settings. At 1920x1080, the Medium preset offers a strong balance, with an average FPS of 72 and a minimum of 61, ensuring smooth gameplay with only occasional dips. The High preset at 1080p averages 54 FPS, which is still playable, but the lower minimum FPS (not measured) could introduce more variability. The Ultra preset at 1080p averages 51 FPS, but given the lack of minimum data, it carries more risk of stutter.

At 2560x1440, the Medium preset is the highest quality option that maintains an average above 55 FPS, with an average of 58 and a minimum of 49. The Low preset at 1440p achieves 74 FPS, but sacrifices visual fidelity. For users who prefer higher resolution, Medium at 1440p is the recommended preset, as it provides a 49 FPS minimum, which is borderline acceptable for a flight simulator where smoothness matters less than in fast-paced titles.

At 3840x2160, no preset delivers a fully satisfactory experience. The Low preset averages 55 FPS, but the Medium preset drops to 43 FPS with a minimum of 36. Given the game’s genre, which relies on steady visuals rather than rapid response, 4K Medium might be acceptable for some, but the data suggests that 1440p Medium or 1080p High offers a more consistent frame rate. The best overall experience, based on the measured rows, is 1080p Medium, which combines a high average FPS (72) with a minimum FPS (61) that indicates stable performance.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its strongest performance. The Low preset averages 92 FPS, which is the highest measured value across all resolutions and settings. Medium averages 72 FPS with a minimum of 61 and a maximum of 82. High averages 54 FPS, and Ultra averages 51 FPS. This shows a clear progression: lowering settings from Ultra to Low yields a 41 FPS improvement, or an 80% increase.

At 2560x1440, performance drops noticeably. Low averages 74 FPS, Medium averages 58 FPS with a minimum of 49 and maximum of 66, High averages 43 FPS, and Ultra averages 41 FPS. The gap between Low and Ultra here is 33 FPS. The Medium preset’s minimum of 49 FPS indicates that the system can sustain playable frame rates, but the High and Ultra presets fall below the 60 FPS threshold that many users consider smooth.

At 3840x2160, the system struggles. Low averages 55 FPS, Medium averages 43 FPS with a minimum of 36 and maximum of 49, High averages 32 FPS, and Ultra averages 31 FPS. The difference between Low and Ultra is 24 FPS. The Medium preset’s minimum of 36 FPS is the lowest measured value in the entire dataset, suggesting that 4K gameplay will involve frequent frame drops even at moderate settings.

The data reveals that the system’s performance scales predictably with resolution and settings. At 1080p, the user has a wide range of viable options, from 51 FPS at Ultra to 92 FPS at Low. At 1440p, only Low and Medium maintain averages above 55 FPS. At 4K, only Low achieves an average above 50 FPS.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and consistent across all settings. For Low settings, the average FPS falls from 92 at 1080p to 74 at 1440p and 55 at 4K. This represents a 19.6% drop from 1080p to 1440p and a 40.2% drop from 1080p to 4K. For Medium settings, the drop is from 72 to 58 to 43, a 19.4% drop and then a 40.3% drop. High settings see a drop from 54 to 43 to 32, a 20.4% and then a 40.7% drop. Ultra settings drop from 51 to 41 to 31, a 19.6% and then a 39.2% drop.

This consistent pattern—a roughly 20% reduction from 1080p to 1440p and another 25% reduction from 1440p to 4K—indicates that the GPU is the primary bottleneck. The RX 6600’s 8 GB memory and 224.0 GB/s bandwidth are insufficient for the pixel throughput required at higher resolutions. The CPU’s performance, with its 12 cores and 24 threads, is not the limiting factor here, as the relative FPS drops are almost identical across all presets, regardless of the CPU workload.

The scaling suggests that the system is heavily GPU-bound at resolutions above 1080p. The Ryzen 9 9900X3D has ample headroom, as evidenced by its high benchmark scores, but the GPU cannot keep up with the increased rendering demands. This is a typical pattern for a high-end CPU paired with a mid-range GPU, where the CPU’s capabilities are wasted at higher resolutions.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor based on the Zen 5 architecture, built on a 4 nm process. It has a base clock of 4.40 GHz and a boost clock of 5.50 GHz, with 128 MB of L3 cache. Its benchmark results are impressive: a Cinebench R23 single-core score of 6739 and a multicore score of 47737, a Geekbench single-core score of 3041 and multicore score of 22884, and a Passmark single-thread score of 4646 with a multithread score of 56154.

For Microsoft Flight Simulator, which can utilize multiple cores for physics, weather, and scenery processing, the CPU’s 12 cores and 24 threads are more than sufficient. The 3DMark 16-thread score of 12490 and max-thread score of 13795 indicate strong multi-threading capabilities. However, the measured FPS data shows that the CPU is not the limiting factor in this system. At 1080p Low, the system achieves 92 FPS, which is a high frame rate, but at 4K Ultra, it drops to 31 FPS. This drop is entirely attributable to the GPU’s inability to render at that resolution.

The CPU’s role is to ensure that the game does not become CPU-bound at lower resolutions. At 1080p, the system achieves 92 FPS at Low settings, which likely approaches the GPU’s maximum output, while the CPU has headroom to spare. The lack of minimum FPS data for most presets prevents a full analysis of frame pacing, but the available data suggests the CPU provides a stable foundation for the game’s simulation logic.

GPU Role

The AMD Radeon RX 6600 is an RDNA 2.0 architecture GPU built on a 7 nm process, with 1792 shading units, 112 TMUs, and 64 ROPs. It has 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. Its clocks are a base of 1626 MHz, a game clock of 2044 MHz, and a boost of 2491 MHz. The GPU’s synthetic benchmarks show an average score of 19036, placing it in the 63rd percentile of all GPUs.

In Microsoft Flight Simulator, the GPU’s limited memory bandwidth and capacity become evident at higher resolutions. At 4K, the system struggles to maintain 60 FPS even at Low settings, averaging 55 FPS. The GPU’s 8 GB memory is likely a constraint, as flight simulators often load large textures and terrain data. The measured FPS at 4K Medium (43 FPS average, 36 FPS minimum) indicates that the GPU is overwhelmed by the rendering load.

The GPU’s performance relative to its rivals is tightly clustered. Its nearest rival, the NVIDIA Quadro K6000, is exactly 0% different in average score, while the RTX 4050 Mobile is 0.1% higher. This suggests the RX 6600 is a competent mid-range card, but it is clearly outmatched by the CPU in this pairing. The GPU’s role is to render the game’s visuals, and at 1080p Medium, it achieves a 72 FPS average with a 61 FPS minimum, which is a reasonable experience. However, any attempt to push higher resolutions or settings exposes its limitations.
