Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title that stresses both the CPU and GPU heavily, and the pairing of the AMD Ryzen 9 5950X with the AMD Radeon RX 6600 XT produces a specific set of trade-offs. The data shows a system that is exceptionally well-balanced for high-refresh 1080p play, but one that becomes increasingly GPU-bound as resolution climbs, ultimately struggling to maintain smooth frame rates at 4K with higher detail settings.

Resolution Scaling

The measured FPS data reveals a clear and predictable pattern: performance degrades significantly as resolution increases from 1920x1080 to 3840x2160. At Low settings, the average frame rate drops from 101 FPS at 1080p to 81 FPS at 1440p and finally to 60 FPS at 4K. This represents a 40% reduction in average FPS from 1080p to 4K at Low settings, indicating that even at the lowest graphical preset, the resolution scaling heavily impacts the rendering workload.

The scaling behavior changes notably with higher settings. At Medium settings, the average FPS drops from 78 at 1080p to 63 at 1440p and 47 at 4K—a 40% drop from 1080p to 4K, similar to Low. However, at High settings, the drop is steeper in relative terms: from 59 FPS at 1080p to 47 FPS at 1440p and 35 FPS at 4K, which is a 41% reduction. At Ultra settings, the pattern continues with 56 FPS at 1080p, 45 FPS at 1440p, and 33 FPS at 4K, a 41% decline.

The fact that the percentage drop from 1080p to 4K is nearly identical across all settings (40-41%) suggests that the limiting component is consistently the GPU at higher resolutions. The RX 6600 XT, with its 8 GB of GDDR6 memory and 128-bit bus, simply cannot keep pace with the pixel count at 4K, regardless of how much the CPU has to spare. At 1080p, the CPU has more headroom to feed the GPU, which is why the frame rates are substantially higher, but even there, the Ultra preset (56 FPS) shows that the GPU is still the primary bottleneck for maximum detail.

FAQ

Q: What is the highest average frame rate achievable with this combo at 1080p?

GPU Role

The AMD Radeon RX 6600 XT is built on the RDNA 2.0 architecture with a Navi 23 chip and features 2048 shading units, 128 texture mapping units, and 64 render output units. Its base clock is 1968 MHz, with a game clock of 2359 MHz and a boost clock of 2589 MHz. The GPU is equipped with 8 GB of GDDR6 memory on a 128-bit bus, providing 256.0 GB/s of bandwidth, and it supports DirectX 12 Ultimate with 32 ray tracing cores.

In Microsoft Flight Simulator, the GPU's role is dominant at higher resolutions. The measured FPS data shows that at 4K Ultra, the average drops to 33 FPS, which is only slightly above the minimum playability threshold. The GPU's performance percentile is 70 among all GPUs, and its nearest rival, the NVIDIA GeForce RTX 2080 SUPER, has a deltaPct of 1.1, meaning the RX 6600 XT is roughly 1.1% slower in average benchmark score. This close competition indicates the RX 6600 XT is a mid-range performer that struggles with heavy 4K loads.

The frame rate data shows that the GPU is the limiting factor at 4K, as the average FPS at High settings (35) is only 2 FPS higher than at Ultra (33). This narrow gap suggests that the GPU is already saturated, and additional detail settings have diminishing returns. At 1080p, the GPU has more headroom, as evidenced by the 101 FPS at Low settings, but the Ultra preset still only reaches 56 FPS, confirming that the GPU is the primary constraint for maximum quality even at lower resolutions.

How This Combo Ranks

The combo of the Ryzen 9 5950X and RX 6600 XT ranks 2571 out of 3714 tested combinations in Microsoft Flight Simulator. This places it in the 31st percentile of all tested combos, meaning roughly 69% of other CPU and GPU pairings outperform it in this specific game. This ranking is notably lower than the CPU's individual percentile of 91, which highlights that the GPU is holding back the overall system performance.

The ranking suggests that while the CPU is high-end, the GPU is the weak link in this pairing for this title. The RX 6600 XT's percentile of 70 among GPUs confirms this assessment. The measured FPS data supports this: at 1080p Low, the system achieves 101 FPS, but at 4K Ultra, it falls to 33 FPS. This wide range of performance indicates that the combo can handle lighter loads well but struggles under the most demanding conditions.

Compared to other combos, this pairing is likely better suited for 1080p or 1440p gaming rather than 4K. The rank of 2571 suggests that users with higher-end GPUs, such as NVIDIA's RTX 2080 SUPER (which is only 1.1% faster in raw GPU benchmarks), are likely to see better results in this game due to more VRAM or higher memory bandwidth. The combo's ranking is a practical indicator that buyers should temper expectations for 4K performance.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture (codenamed Vermeer) and manufactured on a 7 nm process. It has a base clock of 3.40 GHz and a boost clock of 4.90 GHz, with 64 MB of L3 cache and support for DDR4 memory in a dual-channel configuration. The CPU has a TDP of 105 W and ranks in the 91st percentile among all CPUs, with an average benchmark score of 51947.

In Microsoft Flight Simulator, the CPU's role is significant at lower resolutions where the GPU is less taxed. At 1080p Low, the system reaches 101 FPS, which is a strong result that indicates the CPU can feed the GPU effectively at that resolution. The CPU's single-thread score in Cinebench R23 is 1614, and its multi-core score is 26017, showing strong single-core performance that is critical for flight simulation's physics and AI calculations.

However, the CPU's high core count (16 cores, 32 threads) may not be fully utilized in this game, as Microsoft Flight Simulator is known to be more dependent on single-thread performance. The 3DMark single-thread score of 944 and 2-thread score of 1856 suggest that while the CPU has immense multi-threaded capability (3DMark max threads score of 11597), the game may not scale perfectly with all 32 threads. The measured FPS data shows that at 4K Ultra, the average FPS is 33, which is far below the CPU's potential, confirming that the GPU is the bottleneck in this scenario.

The CPU's nearest rival, the Intel Core i7-14700, has a deltaPct of -0.7, meaning the 5950X is 0.7% faster in average benchmark score. This close competition indicates that the 5950X is a top-tier CPU that should not be a limiting factor in most gaming scenarios, but the RX 6600 XT's limitations cap the overall performance.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best performance. With Low settings, the average FPS is 101, providing a smooth experience for fast-paced flight. Medium settings yield an average of 78 FPS with a minimum of 66 and maximum of 90, showing good consistency. High settings drop the average to 59 FPS, while Ultra settings produce 56 FPS. The gap between High and Ultra is only 3 FPS, suggesting that the GPU is nearing its limits at this resolution with high detail.

At 2560x1440, performance takes a noticeable hit. Low settings average 81 FPS, which is still playable, but Medium drops to 63 FPS (minimum 54, maximum 73). High settings average 47 FPS, and Ultra settings average 45 FPS. The difference between High and Ultra narrows to just 2 FPS, indicating the GPU is becoming more constrained. The 1440p Medium preset (63 FPS) is the most balanced option for maintaining playability without sacrificing too much visual quality.

At 3840x2160, the GPU struggles significantly. Low settings average 60 FPS, which is just at the threshold for playable performance. Medium settings average 47 FPS with a minimum of 40 and maximum of 54, showing visible frame dips. High settings average 35 FPS, and Ultra settings average 33 FPS. The 4K results show that this combo is not suitable for high-detail 4K gaming, as even the Medium preset fails to maintain a consistent 60 FPS. The data shows that users should stick to 1080p or 1440p for a better experience with this pairing.
