Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding flight simulation title that stresses both the processor and the graphics card in unique ways. This analysis examines the measured performance of the AMD Ryzen 9 5900X paired with the AMD Radeon RX 6600 XT across three resolutions and four quality presets. The data shows a system that can handle the simulator at playable frame rates, though the experience varies significantly depending on the resolution and settings chosen. The benchmark results provide a clear picture of where this combination's strengths and limitations lie.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, with a base clock of 3.70 GHz and a boost clock of 4.80 GHz. It features a substantial 64 MB of L3 cache, which is beneficial for the complex world-loading and physics calculations inherent to flight simulation. In synthetic benchmarks, the processor scores 33,150 in Cinebench R23 multi-core and 4,680 in single-core, indicating robust multi-threaded performance and strong single-thread capability. The CPU's percentile ranking of 90 vs all CPUs places it in the upper echelon of processors.

In the context of this game, the CPU's role is critical for processing the simulation's core logic. The measured frame rates show that the processor is not the primary bottleneck at lower resolutions. At 1920x1080 with Low settings, the system achieves 97.9 FPS, which is the highest average recorded in this dataset. This high frame rate suggests that the CPU can feed the GPU efficiently at this resolution. However, the margin for CPU headroom narrows as the resolution and settings increase, shifting the bottleneck to the graphics card. Compared to its nearest rivals in the CPU benchmark database, the Ryzen 9 5900X shows a 0.2% higher average score than the AMD EPYC 4245P and a 0.9% higher score than the Intel Core i7-13700F, while trailing the AMD Ryzen 7 PRO 8845HS by 0.7% and the Intel Core i7-13700 by 1%. These small deltas indicate that the CPU's performance is well within the expected range for high-end desktop processors.

GPU Role

The AMD Radeon RX 6600 XT is built on the RDNA 2.0 architecture with a Navi 23 chip, featuring 8 GB of GDDR6 memory on a 128-bit bus, providing 256.0 GB/s of bandwidth. Its boost clock reaches 2589 MHz, and the memory runs at 2000 MHz (16 Gbps effective). The GPU's raw compute capabilities include 10.60 TFLOPS of FP32 performance. With a percentile ranking of 71 vs all GPUs, it sits in the mid-to-upper range of graphics cards. In the PassMark G3D benchmark, the card scores 16,461, and its average benchmark score is 27,985.

The GPU's performance in this game is the defining factor for the experience. At 1920x1080, the RX 6600 XT delivers playable frame rates across all presets, from 97.9 FPS at Low to 56.1 FPS at Ultra. However, the 8 GB VRAM buffer becomes a limiting factor at higher resolutions. At 2560x1440, the Ultra preset yields 46.7 FPS, and at 3840x2160, the Ultra preset drops to 31 FPS. The GPU's nearest rival, the NVIDIA GeForce RTX 3070, has an average score that is 0.9% higher, while the NVIDIA GeForce GTX 980 Ti is 0.1% lower. This places the RX 6600 XT in a competitive position for its class, but the data shows that 4K Ultra settings are beyond its comfortable reach in this simulator.

Settings Recommendations

The measured FPS data provides clear guidance on optimal settings for this combination. For a smooth experience at 1920x1080, the High preset delivers 59.9 FPS, which is a good balance. However, the Medium preset achieves 79.4 FPS, offering a significant performance boost with a likely minimal visual impact. The Low preset at 97.9 FPS is the highest measured, but it may compromise too much visual fidelity for a simulator where scenery detail is important.

At 2560x1440, the choice is more constrained. The Medium preset achieves 61.2 FPS, which is the recommended choice for a balance of visual quality and performance. The High preset at 47.3 FPS and Ultra at 46.7 FPS are nearly identical in performance, suggesting that the Ultra preset's additional effects are not the primary cost; the resolution itself is taxing the GPU. At 3840x2160, the Low preset is the only option that provides a comfortable frame rate at 57.9 FPS. The Medium preset at 43.6 FPS and High at 33.2 FPS are playable but may suffer from stutters in dense areas. The Ultra preset at 31 FPS is below the threshold for a smooth experience.

The data indicates that the best experience is achieved at 1920x1080 with Medium or High settings, or at 2560x1440 with Medium settings. Pushing to 4K requires dropping to Low settings to maintain a smooth frame rate, which negates the visual benefits of the higher resolution.

How This Combo Ranks

The combination of the AMD Ryzen 9 5900X and AMD Radeon RX 6600 XT ranks 1362 out of 1795 tested combos in this game. This places it in the lower-middle portion of the database, which is noteworthy given the individual component benchmarks. The CPU ranks in the 90th percentile, and the GPU ranks in the 71st percentile, suggesting a potential imbalance. The low combo rank implies that the GPU is the limiting factor for this specific game, dragging the overall ranking down despite the strong CPU.

This ranking indicates that while the CPU is more than capable of handling the simulation's logic, the GPU cannot keep pace at higher resolutions and settings. The measured FPS data supports this interpretation, as the frame rates scale predictably with resolution, showing a clear GPU bottleneck. The gap between the CPU and GPU performance tiers is the primary reason for the combo's modest ranking. For users with this configuration, the data suggests that the system is best suited for 1080p or 1440p gaming, where the GPU can deliver acceptable frame rates.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across all tested configurations.

At 1920x1080, the frame rates are as follows:

• Low: 97.9 FPS
• Medium: 79.4 FPS
• High: 59.9 FPS
• Ultra: 56.1 FPS

The progression from Low to Ultra shows a steady decline, with the largest single drop occurring between Medium and High, a decrease of 19.5 FPS. The difference between High and Ultra is relatively small at 3.8 FPS, suggesting diminishing returns at the highest preset.

At 2560x1440, the frame rates are:

• Low: 77.6 FPS
• Medium: 61.2 FPS
• High: 47.3 FPS
• Ultra: 46.7 FPS

Here, the performance drops are more evenly distributed. The gap between Medium and High is 13.9 FPS, while High and Ultra are nearly identical with a 0.6 FPS difference. This indicates that at 1440p, the Ultra preset adds little visual cost beyond High.

At 3840x2160, the frame rates are:

• Low: 57.9 FPS
• Medium: 43.6 FPS
• High: 33.2 FPS
• Ultra: 31 FPS

The 4K results show a severe performance penalty. The drop from Low to Medium is 14.3 FPS, and from Medium to High is 10.4 FPS. The Ultra preset is the lowest measured at 31 FPS, which is below the generally accepted threshold for smooth gameplay. The data clearly shows that 4K is only viable with the Low preset for this combination.
