Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title, and the combination of the AMD Ryzen 7 5800XT and AMD Radeon RX 6750 XT produces a clear hierarchy of performance across its preset and resolution options. The data shows that this pairing is capable of delivering smooth, playable frame rates, but the specific settings chosen drastically alter the experience, shifting the bottleneck between the processor and the graphics card depending on the workload.

Settings Recommendations

The benchmark results indicate that the Low preset offers the most consistently high performance, but it comes at the cost of visual fidelity. At 1920x1080, the Low preset yields an average of 126.2 FPS, which drops to 99.8 FPS at 2560x1440 and 75.5 FPS at 3840x2160. These figures suggest that the Low preset is primarily limited by the CPU's single-thread performance, as the frame rate scales almost linearly with resolution, a classic sign of a processor-bound scenario.

For users seeking a balance between visual quality and performance, the Medium preset is the most compelling choice. At 1080p, it delivers an average of 95.5 FPS, which is a substantial 23 FPS drop from Low but still well within the range of smooth gameplay. The scaling to higher resolutions is also more moderate, with 78 FPS at 1440p and 59.5 FPS at 4K. This indicates that the GPU is beginning to take on a more significant role, but the CPU still provides enough headroom to maintain high frame rates.

The High and Ultra presets show a significant performance penalty, particularly at higher resolutions. At 1080p, High averages 72.3 FPS and Ultra averages 72.5 FPS, showing that the game is heavily GPU-limited at these settings. The situation worsens at 4K, where High drops to 40.4 FPS and Ultra to 39.4 FPS. These numbers are below the 60 FPS threshold that many consider the baseline for a smooth experience. Therefore, while these presets offer the best visuals, the data suggests they are only suitable for users who prioritize image quality over frame rate, or who are playing at 1080p where the frame rate remains acceptable. The optimal experience is found on the Medium preset, which provides a robust frame rate across all tested resolutions without fully sacrificing the game's graphical detail.

GPU Role

The AMD Radeon RX 6750 XT, with its 12 GB of GDDR6 memory on a 192-bit bus, plays a crucial role in determining the frame rate at higher settings and resolutions. The GPU's memory bandwidth of 432.0 GB/s is a key factor in how it handles the vast texture data and geometry of a flight simulator. The 12 GB frame buffer is also a significant asset, as it allows the card to hold more assets without spilling over into system memory, which can cause stutters.

The GPU's clock speeds, with a base of 2150 MHz and a boost of 2600 MHz, are relatively high, and the data shows their impact. The transition from Medium to High at 1080p results in a 23.2 FPS drop, and from High to Ultra, the frame rate is essentially flat (72.3 to 72.5 FPS). This plateau indicates that at Ultra settings, the game is pushing the GPU to its absolute limit, and the additional graphical features have a minimal impact on the already low frame rate. At 4K, the GPU is the clear limiting factor across all presets. The difference between Low and Medium is 16 FPS, and between Medium and High is 19.1 FPS, showing that the GPU's compute and fillrate capabilities are being taxed heavily. The RX 6750 XT is a capable card for 1440p gaming, but the data confirms that it is not a 4K powerhouse for this specific title, especially when aiming for high visual quality.

Resolution Scaling

The scaling of frame rates from 1080p to 4K reveals a clear picture of the system's bottleneck. On the Low preset, the performance drop from 1080p to 4K is 50.7 FPS (126.2 to 75.5). This is a large drop, but the frame rate remains high, indicating that the CPU is still the primary limiter. The game's simulation logic and draw calls are heavily dependent on CPU performance, and at low graphical settings, the GPU is not stressed enough to become the bottleneck.

As settings increase, the GPU's influence becomes more pronounced. On the Medium preset, the drop from 1080p to 4K is 36 FPS (95.5 to 59.5). The frame rate at 4K is still playable, but the scaling is less linear, suggesting that the GPU is starting to share the load. On the High preset, the drop from 1080p to 4K is 31.9 FPS (72.3 to 40.4). The 4K result is now below 60 FPS, and the scaling shows that the GPU is the dominant factor. The Ultra preset shows a similar drop of 33.1 FPS (72.5 to 39.4), with the 4K frame rate being the lowest of all presets. This data conclusively shows that while the CPU is the bottleneck at low settings, the GPU becomes the limiting component at High and Ultra settings, particularly at 4K resolution.

How This Combo Ranks

In the grand scheme of tested hardware combinations, this pairing of the Ryzen 7 5800XT and RX 6750 XT holds a solid position. The combo ranks 908th out of 1795 tested combinations for Microsoft Flight Simulator, placing it in the top half of all systems benchmarked. This is a respectable position, indicating that the hardware is well-matched for the game's demands.

Looking at the individual components, the CPU's performance is a strong contributor to this ranking. The AMD Ryzen 7 5800XT sits in the 86th percentile of all CPUs, and its average benchmark score of 29774 places it in close competition with several other processors. Its nearest rivals, such as the AMD Ryzen 7 PRO 5755GE (score 29740, delta 0.1%) and the AMD Ryzen 7 6800HS (score 29856, delta -0.3%), show that the 5800XT is right in the middle of a performance cluster. This suggests that the CPU is delivering performance on par with modern mid-range and high-end mobile and desktop parts.

The GPU also performs admirably, ranking in the 79th percentile of all GPUs. Its average benchmark score of 35327 is just slightly above the AMD Radeon RX 5600M (score 35264, delta 0.2%) and just below the NVIDIA GeForce RTX 3080 (score 35787, delta -1.3%). This shows that the RX 6750 XT is a very capable performer in its own right, offering performance in the same league as some higher-tier cards. The combo's overall rank confirms the balance between these two components, which together provide a strong, if not top-tier, experience in this simulator.

CPU Role

The AMD Ryzen 7 5800XT is the anchor of this system's processing power, and its specifications directly influence the game's performance in CPU-bound scenarios. With 8 cores and 16 threads based on the Zen 3 architecture, it offers strong multi-threaded capabilities. Its base clock of 3.80 GHz and boost clock of 4.80 GHz are significant, and the benchmark data shows that the single-thread performance is crucial for Microsoft Flight Simulator. The CPU's 3dmark_single_thread score of 959 and cinebench_r23_singlecore score of 3359 are solid, but the game's engine relies heavily on a single main thread for simulation tasks.

The data's evidence of CPU bottlenecking is most apparent at 1080p with the Low preset, where the frame rate is 126.2 FPS. This is a very high number that is unlikely to be limited by the GPU, which is underutilized at these settings. The fact that the frame rate drops significantly when moving to Medium (95.5 FPS) and High (72.3 FPS) confirms that the game is still heavily reliant on the CPU even as the GPU load increases. The CPU's performance is further contextualized by its rivals; it is essentially tied with the AMD Ryzen 7 PRO 5755GE (delta 0.1%) and the AMD Ryzen 7 7840H (delta -0.3%), showing that its processing power is competitive with newer mobile parts. The 5800XT's strong multi-threaded scores, like the cinebench_r23_multicore score of 23794, ensure that it can handle the background tasks and AI calculations in the simulator without becoming a weak link. However, the data suggests that for this game, its high single-thread performance is the more critical asset, and it is this strength that allows the system to achieve high frame rates at lower graphical settings.
