Microsoft Flight Simulator

Microsoft Flight Simulator is a uniquely demanding title that stresses both the processor and graphics card in ways most other games do not. The data for this configuration, pairing the AMD Ryzen 5 9600X with the AMD Radeon RX 6600, provides a clear picture of where the bottlenecks lie and how the system scales across resolutions and quality presets. The Ryzen 5 9600X is a 6-core, 12-thread processor from the Zen 5 Granite Ridge architecture, running on the AMD Socket AM5 platform with a base clock of 3.90 GHz and a boost clock of 5.40 GHz. This CPU sits in the 85th percentile compared to all CPUs, and its average benchmark score of 28,246 is nearly identical to its nearest rivals, including the Intel Core i5-13490F and AMD Ryzen 5 230, which score 28,173 and 28,164 respectively, representing a negligible delta of 0.3%. On the graphics side, the Radeon RX 6600 is a RDNA 2.0 part with 8 GB of GDDR6 memory on a 128-bit bus, providing a memory bandwidth of 224.0 GB/s. It holds a 69th percentile rank among all GPUs, with an average benchmark score of 25,235, placing it in a tight cluster with the AMD Radeon 890M and NVIDIA GeForce RTX 3060 Ti, the latter of which is only 0.5% faster. The measured FPS data reveals a system that is heavily GPU-limited at higher settings and resolutions, but capable of delivering playable frame rates when settings are adjusted appropriately.

CPU Role

The Ryzen 5 9600X’s performance profile suggests it is more than capable of feeding the Radeon RX 6600 in Microsoft Flight Simulator, but the data indicates that the CPU is not the primary limiting factor in most scenarios. With 6 cores and 12 threads, the processor leverages a 32 MB shared L3 cache and a 4 nm process node from TSMC, which contributes to strong single-thread performance. Its Cinebench R23 single-core score of 3,603 and multi-core score of 25,525 are indicative of a modern, high-IPC design. The benchmark results show that the CPU’s average score of 28,246 is effectively on par with its nearest rivals, such as the AMD Ryzen 7 8845HS which scores 28,369 (a delta of -0.4%), suggesting that any performance differences in game are not due to CPU compute limitations. In the measured data, the lowest FPS figures occur at 4K Ultra settings, where the frame rate drops to 33.2 FPS. This pattern, where FPS decreases as resolution and settings increase, points to the GPU being the bottleneck. The CPU’s role is to maintain a stable frame pacing floor, and given that even at 1080p Low settings the system only reaches 91.7 FPS, it is clear that the CPU is not capping the frame rate at a low threshold. The processor’s 5.40 GHz boost clock and robust PassMark single-thread score of 4,570 provide ample headroom for the simulation’s complex physics and scenery calculations, meaning the variance in FPS across settings is almost entirely attributable to the graphics card’s workload.

GPU Role

The Radeon RX 6600 is the decisive component in this configuration, and its 8 GB VRAM capacity and 128-bit memory interface are key factors in its performance ceiling. The GPU’s boost clock of 2491 MHz and game clock of 2044 MHz allow it to reach a texture rate of 279.0 GTexel/s and a pixel rate of 159.4 GPixel/s. However, the data shows a stark drop-off in performance as settings are raised. At 1080p, moving from Low to Ultra settings reduces the average FPS from 91.7 to 51.5, a decline of 40.2 FPS. This is a direct consequence of increased shader complexity and texture detail, which the GPU’s 1,792 shading units must process. The GPU’s average benchmark score of 25,235 is nearly identical to the AMD Radeon 6700M, which scores 25,180, and the AMD Radeon RX 580 2048SP, which scores 25,287, indicating that its raw compute power is well understood. The most telling data point is the 4K Ultra result, where the system averages just 33.2 FPS. At this resolution, the GPU is clearly overwhelmed, and the 8 GB VRAM may also be a limiting factor, as the game is known for its high-resolution textures. The fact that the GPU holds a 69th percentile rank among all GPUs, while the CPU holds an 85th percentile rank, reinforces the notion that the RX 6600 is the weaker link in this pairing for this specific title.

Resolution Scaling

The FPS data shows a predictable and consistent scaling pattern across resolutions, which helps identify the limiting component. At Low settings, the average FPS drops from 91.7 at 1080p to 75.6 at 1440p and then to 51.6 at 4K. This represents a 44% reduction in frame rate from 1080p to 4K, which is a significant hit. When examining High settings, the FPS drops from 54.6 at 1080p to 44.1 at 1440p and then to 31.7 at 4K. The 4K High result is the lowest FPS in the entire dataset, confirming that the GPU is the primary bottleneck at this resolution. The scaling is not linear, which is typical for a GPU-bound scenario, as the pixel count increases by more than double from 1440p to 4K. The delta between 1080p and 1440p High is 10.5 FPS, while the delta between 1440p and 4K High is 12.4 FPS. This indicates that the GPU is struggling more as resolution increases, and the CPU’s performance is not a factor. The data suggests that for a smooth experience, users should avoid 4K with this GPU, as even Medium settings at 4K only yield 42.2 FPS. The sweet spot for resolution appears to be 1440p, where Low settings achieve 75.6 FPS, providing a good balance between visual fidelity and frame rate. The 1080p results are the most playable, with all settings except Ultra staying above 54 FPS, but the margin between 1080p and 1440p is not huge, suggesting that the GPU’s memory bandwidth of 224.0 GB/s is a limiting factor at higher resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this configuration depend on the user’s priority for frame rate versus visual quality. At 1080p, the Medium preset offers the best balance, delivering an average of 73.2 FPS, which is a significant improvement over the High preset’s 54.6 FPS, while still providing better visual detail than Low’s 91.7 FPS. The jump from Medium to High costs 18.6 FPS, which is a substantial penalty for what is often a marginal visual improvement in a flight simulator. For users with a 1440p monitor, the Low preset is the only one that provides a consistently smooth experience, with an average of 75.6 FPS. The Medium preset at 1440p drops to 58.7 FPS, which is still playable but may exhibit stutters in dense scenery. The High preset at 1440p, at 44.1 FPS, is borderline, and Ultra at 38.6 FPS is not recommended for a smooth experience. At 4K, the data is clear: no preset provides an ideal experience. The Low preset at 51.6 FPS is the only one above 50 FPS, but it is still below the 60 FPS target that many users prefer. The Ultra preset at 33.2 FPS is only suitable for screenshots or slow, cinematic flying. Therefore, the data suggests that users should prioritize 1080p with Medium settings for the best overall experience, or 1440p with Low settings if a higher resolution is preferred. This configuration is not suited for 4K gaming in this title.

Measured FPS Breakdown

The complete set of measured average FPS values is as follows. At 1920x1080, the Low preset yields 91.7 FPS, Medium yields 73.2 FPS, High yields 54.6 FPS, and Ultra yields 51.5 FPS. Moving to 2560x1440, the scores are 75.6 FPS for Low, 58.7 FPS for Medium, 44.1 FPS for High, and 38.6 FPS for Ultra. At 3840x2160, the results are 51.6 FPS for Low, 42.2 FPS for Medium, 31.7 FPS for High, and 33.2 FPS for Ultra. The data reveals an interesting anomaly where 4K Ultra (33.2 FPS) is slightly higher than 4K High (31.7 FPS), which is likely due to variation in the simulated flight scene or a non-linear workload. The overall combo rank for this configuration in the game is 1,442 out of 1,795 tested combinations, placing it in the lower-mid tier of all possible hardware pairings. The most striking takeaway is the severe FPS penalty for enabling Ultra settings, which costs over 40 FPS compared to Low at 1080p. For users who prioritize a smooth, high-refresh-rate experience, the Low or Medium presets at 1080p are the only viable options based on this data, while those who value visual fidelity will find the High preset at 1080p to be a reasonable compromise, though still below 60 FPS.
