Microsoft Flight Simulator

Microsoft Flight Simulator remains one of the most demanding titles in the benchmark database, and the pairing of the AMD Ryzen 5 5600X with the AMD Radeon RX 6600 produces a dataset that clearly illustrates the balance between CPU simulation overhead and GPU rendering load. The measured results across three resolutions and four quality presets show a configuration that is consistently capable of playable frame rates at 1080p, but one that progressively yields ground as resolution scales upward. This analysis breaks down the measured FPS, the role of the processor, and how this specific combination ranks against the broader field of tested hardware.

Resolution Scaling

The measured FPS data reveals a pronounced sensitivity to resolution, which is a classic indicator of a GPU-bound scenario at higher pixel counts. Moving from 1920x1080 to 2560x1440 at Ultra settings, the average frame rate drops from 49.4 FPS to 39.5 FPS, a reduction of roughly 20%. The scaling continues to 3840x2160, where the Ultra preset yields only 27.6 FPS, a further 30% decline from the 1440p result. This steep downward trajectory is the signature of a graphics card that is reaching its computational limits as pixel throughput demands increase.

At the Low preset, the same pattern holds but with higher absolute numbers. The 1080p Low result of 94.4 FPS falls to 71.2 FPS at 1440p, and then to 56.2 FPS at 4K. The percentage drops between each resolution step are consistent, suggesting that the RX 6600’s rendering pipeline is the primary bottleneck across all settings. The data indicates that the CPU is not the limiting factor in these higher-resolution scenarios; if it were, the frame rate would remain relatively flat as resolution increases, which is not the case here.

The gap between Low and Ultra settings widens as resolution increases, which further emphasizes the GPU’s dominance in the performance equation. At 1080p, the difference between Low (94.4 FPS) and Ultra (49.4 FPS) is 45 FPS. At 4K, that same gap shrinks to 28.6 FPS (56.2 FPS vs. 27.6 FPS). This compression at higher resolutions is typical for a card with 8 GB of memory and a 128-bit bus, as the fill rate and bandwidth constraints become more pronounced. The benchmark results indicate that users targeting 4K will need to make significant compromises in visual fidelity to maintain a playable experience, while 1080p offers a much wider operating window across all presets.

CPU Role

The AMD Ryzen 5 5600X is a 6-core, 12-thread processor based on the Zen 3 architecture, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. In synthetic benchmarks, this CPU achieves a single-thread score of 917 in 3DMark and 2622 in Cinebench R23, which places it in the 78th percentile of all tested CPUs. For a flight simulator like Microsoft Flight Simulator, which is known for heavy single-threaded simulation logic, this level of single-core performance is critical.

The data shows that the CPU is likely not the primary constraint in this combo, especially at higher resolutions. At 1080p Low, the system achieves 94.4 FPS, which is a strong result that suggests the processor can feed the GPU adequately at lower loads. However, the CPU’s role becomes more apparent when looking at the scaling from Low to Ultra at 1080p. The drop from 94.4 FPS to 49.4 FPS is substantial, and while this is largely a GPU load increase, the CPU’s ability to maintain a stable frame pacing in complex flight scenarios is a factor. The CPU’s multicore performance, with a Cinebench R23 multicore score of 18578, ensures background tasks and physics calculations do not starve the rendering thread.

Compared to its nearest rivals, the 5600X is closely matched. It sits just 0.3% behind the AMD Ryzen 5 5600GT and the Intel Core i7-10700 in average benchmark score, and 0.5% behind the Intel Core i5-12490F. It is 0.7% ahead of the Intel Xeon 6325P. This tight grouping suggests that for this game, the 5600X provides a level of CPU performance that is squarely in the mainstream sweet spot, neither exceeding nor falling behind its direct competition in a way that would significantly alter the measured FPS. The 65W TDP and 32 MB of L3 cache are adequate for the simulation’s demands, but the data does not suggest any CPU headroom that would unlock higher frame rates if the GPU were upgraded.

How This Combo Ranks

Within the database of tested hardware combinations, this specific pairing of the Ryzen 5 5600X and the Radeon RX 6600 holds a rank of 1481 out of 1795 combos for Microsoft Flight Simulator. This places it in the lower portion of the ranking, which is consistent with the GPU’s mid-range positioning. The RX 6600 itself sits in the 69th percentile of all GPUs, with an average benchmark score of 25235, which is nearly identical to its nearest rivals. The Radeon 890M and the Radeon RX 580 2048SP are essentially tied with it (0% and -0.2% delta, respectively), while the RX 6700M is 0.2% faster and the RTX 3060 Ti is 0.5% faster.

The combo’s rank of 1481 out of 1795 indicates that there are many other pairings that achieve higher average frame rates in this specific title. This is not surprising given that Microsoft Flight Simulator is extraordinarily demanding on both the CPU and GPU, and the RX 6600 is a card designed for 1080p gaming rather than high-refresh or high-resolution flight simulation. The data suggests that while the combo is functionally playable at 1080p with adjusted settings, it is far from an optimal configuration for this game when compared to the breadth of hardware available in the database. The rank reflects the aggregate performance across all tested settings and resolutions, where the 4K Ultra result of 27.6 FPS significantly drags down the overall standing.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across all standard resolutions and quality presets. At 1920x1080, the system delivers playable frame rates across the board. The Low preset achieves an average of 94.4 FPS, which is smooth for a flight sim. Medium drops to 70.4 FPS, and High yields 55.4 FPS. The Ultra preset, which is the most visually demanding, still manages an average of 49.4 FPS, which is acceptable for a non-competitive title where frame pacing is more important than raw speed.

Moving to 2560x1440, the frame rates become more constrained. Low produces 71.2 FPS, which remains fluid. Medium drops to 56.7 FPS, and High falls to 43.2 FPS. The Ultra preset is the first to dip below the 40 FPS threshold, averaging 39.5 FPS. This suggests that 1440p is only viable for this combo if the user is willing to accept Medium or High settings, as Ultra approaches the edge of smoothness.

At 3840x2160, the RX 6600 clearly struggles to keep up with the pixel load. Low yields 56.2 FPS, which is still playable, but Medium drops to 41.9 FPS. High falls to 31.5 FPS, and Ultra bottoms out at 27.6 FPS. The data indicates that 4K is only realistic with Low settings, and even then, the frame rate is not high enough to guarantee a consistently smooth experience in dense urban environments or during weather effects. The progression from 1080p Low (94.4 FPS) to 4K Ultra (27.6 FPS) shows a total performance scaling factor of roughly 3.4x, which is a direct reflection of the GPU’s memory bandwidth and compute limitations.

FAQ
