Microsoft Flight Simulator

Microsoft Flight Simulator is a notoriously demanding title, and the benchmark data for the AMD Ryzen 9 5900X paired with the AMD Radeon RX 570 paints a clear picture of a system that is heavily constrained by its graphics card. The measured frame rates across all resolutions and settings are consistently low, indicating that this combination is not capable of delivering a smooth flight simulation experience at modern display standards. The data shows a hardware pairing where the CPU’s substantial processing power is largely left untapped, as the GPU becomes the definitive bottleneck in nearly every scenario.

Resolution Scaling

The performance drop from 1080p to 4K is stark and unequivocally demonstrates that the AMD Radeon RX 570 is the limiting component. At the "Low" preset, the average frame rate falls from 46.3 FPS at 1920x1080 to 41.2 FPS at 2560x1440, a modest decline that continues to 26.1 FPS at 3840x2160. This scaling pattern is typical of a GPU-bound scenario where the increase in pixel count directly taxes the renderer. The transition from 1440p to 4K represents a particularly steep drop of over 36%, underscoring the GPU's struggle with the 4K resolution's 8.3 million pixels.

The trend is even more pronounced at higher graphical presets. At "High" settings, the average frame rate goes from 28.1 FPS at 1080p to 23.7 FPS at 1440p, and then plummets to 16.6 FPS at 4K. The "Ultra" preset, which is the most demanding, shows the GPU's limitations most severely, with frame rates falling from 29.7 FPS at 1080p to 24.9 FPS at 1440p and finally to a mere 13.4 FPS at 4K. This consistent and significant degradation as resolution increases is the definitive signature of a GPU bottleneck. The CPU, a 12-core, 24-thread AMD Ryzen 9 5900X, is more than capable of handling the simulation's physics and AI calculations, but the RX 570's 4 GB of GDDR5 memory and 224.0 GB/s bandwidth are simply overwhelmed by the demands of higher resolutions.

The data indicates that 1080p is the only resolution where the combination approaches a playable state, and even then, only at lower presets. The jump from 1080p to 1440p at "Medium" settings, for example, results in a 22.8% performance loss, from 40.2 FPS to 31.0 FPS. This reinforces the idea that for a smoother experience, the resolution must be kept low. The frame rates at 4K across all presets are below 27 FPS, which is far from a smooth experience for a flight simulator that requires precise control. The scaling analysis clearly shows that any attempt to increase resolution will be met with disproportionate performance penalties, proving that the RX 570 is the primary barrier to a higher-fidelity experience.

Settings Recommendations

Given the measured data, the optimal settings for this hardware combination are a trade-off between visual fidelity and a minimally acceptable frame rate. The only configuration that breaks the 60 FPS barrier is the "Low" preset at 1920x1080, achieving an average of 46.3 FPS. This is the clear recommendation for any user prioritizing smoothness and responsiveness, as it provides the best chance of maintaining a stable simulation. While not hitting 60 FPS, the "Low" preset at 1080p is the most playable scenario in the entire dataset.

For users who want better visuals, the "Medium" preset at 1920x1080 offers a compromise, with an average of 40.2 FPS. This is a 13.2% performance hit compared to "Low" at the same resolution, but it likely provides a noticeably improved visual experience in terms of terrain detail and lighting. The "High" preset at 1080p drops to 28.1 FPS, which is a significant step down and may begin to feel sluggish. The "Ultra" preset at 1080p yields an average of 29.7 FPS, which is slightly higher than "High" but still well below the smoothness threshold and not worth the potential for increased stuttering.

At 2560x1440, the "Low" preset is the only viable option, with an average of 41.2 FPS. All other presets at this resolution fall below 32 FPS, which is generally considered too choppy for a game that requires fine control over an aircraft. The data strongly suggests that 4K resolution should be avoided entirely, as even the "Low" preset only manages an average of 26.1 FPS. The "Medium," "High," and "Ultra" presets at 4K are all in the teens or low 20s, which is not a playable experience. In summary, the "Low" preset at 1080p is the recommended configuration, with the "Medium" preset at 1080p as a secondary option for those who can tolerate lower frame rates for better graphics.

How This Combo Ranks

The performance of this specific combination is near the bottom of the database. The data shows a combo rank of 1703 out of 1795 tested combinations, placing it in the bottom 5% of all systems. This low ranking is a direct result of the significant GPU bottleneck discussed earlier. The AMD Ryzen 9 5900X is a powerful processor, ranking in the 90th percentile against all CPUs, but it is held back by the AMD Radeon RX 570, which, despite being in the 74th percentile for GPUs, is simply not suited for the extreme demands of this flight simulator at higher settings.

The disparity between the components is clear when looking at their individual benchmark scores. The CPU has an average benchmark score of 39453, while the GPU has an average score of 30158. This suggests a pair of mid-to-high-range components, but their combined performance in this specific game is exceptionally poor. The combo's rank of 1703 indicates that there are 92 other tested combinations that perform even worse than this one. This places the system in the lowest tier for Microsoft Flight Simulator, confirming that while the CPU is a strong foundation, the GPU choice severely limits the entire system's gaming potential. The overall experience is dictated by the weakest link, and in this case, that link is the graphics card.

GPU Role

The AMD Radeon RX 570 is the primary determinant of this system's performance in Microsoft Flight Simulator. Its specifications reveal why it struggles so significantly. The GPU features 4 GB of GDDR5 memory on a 256-bit bus, providing a bandwidth of 224.0 GB/s. This memory configuration is a major limiting factor at higher resolutions, where the large textures and complex geometry of the flight simulator easily exceed the available frame buffer. The benchmark data supports this, as performance degrades sharply when moving from 1080p to 1440p and 4K.

The GPU's clock speeds are also a factor. With a base clock of 1168 MHz and a boost clock of 1244 MHz, the RX 570 is running at a modest frequency for its architecture. The chip, codenamed Polaris 20, is built on a 14 nm process and features 2048 shading units. While this provides a theoretical FP32 performance of 5.095 TFLOPS, the data shows that this raw compute power is insufficient for the simulation's rendering load. The GPU's performance percentile of 74 against all other GPUs may suggest it is an average card, but its performance in this specific title is far below average due to the unique demands of a flight simulator.

The data shows a clear correlation between the GPU's workload and frame rate. As the settings are increased from "Low" to "Ultra," the average FPS drops consistently across all resolutions. This is the GPU being tasked with more complex shaders, higher-resolution textures, and more detailed effects. For example, at 1080p, the drop from "Low" to "Ultra" is from 46.3 FPS to 29.7 FPS. At 4K, the drop is from 26.1 FPS to 13.4 FPS. The RX 570's 4 GB VRAM is a likely culprit for the severe 4K performance, as it is likely being forced to swap data to system memory. The GPU's role is therefore one of a strict limiter, preventing the powerful Ryzen 9 5900X from ever showcasing its full potential in this application.
