Microsoft Flight Simulator

The AMD Ryzen 7 5700X3D and AMD Radeon RX 6750 XT combination delivers a playable but demanding experience in Microsoft Flight Simulator, ranking in the 51st percentile of all tested combos. The data shows that this pairing is balanced at 1440p, where the CPU’s large cache and the GPU’s bandwidth align to produce smooth frame rates, while 4K Ultra pushes the system to its limits. The benchmark results indicate that users should prioritize the High preset at 1440p for the best balance of visual fidelity and performance, as it maintains an average above 60 FPS without the steep cost of Ultra settings.

CPU Role

The AMD Ryzen 7 5700X3D is an 8-core, 16-thread processor based on the Zen 3 architecture, with a base clock of 3.00 GHz and a boost clock of 4.10 GHz. Its defining feature is the 96 MB of shared L3 cache, which is critical for Microsoft Flight Simulator’s heavy reliance on streaming terrain and aircraft data. The CPU’s benchmark scores reflect its strong multi-threaded performance, with a Cinebench R23 multi-core score of 22,366 and a PassMark multi-thread score of 26,318. In single-threaded tasks, it scores 3,157 in Cinebench R23, which is adequate for the game’s primary simulation logic.

Compared to its nearest rivals, the 5700X3D is effectively tied with the Intel Core i7-1360P, scoring just 0.2% higher in average benchmark scores. It also edges out the AMD Ryzen 5 7600X3D by 0.3% and the Intel Core i5-11600 by 0.5%. However, the AMD Ryzen AI Max 385 is 0.6% ahead, showing that the 5700X3D sits in a very tight performance band. The CPU’s 82nd percentile ranking among all CPUs indicates that it is a capable part, but not a top-tier performer, meaning that at higher resolutions and settings, the GPU will become the limiting factor.

In this game, the CPU’s role is most evident at 1080p and low settings, where the 126.3 FPS average shows that the 5700X3D can feed the GPU effectively. However, as resolution increases to 4K, the frame rate drops significantly, indicating that the CPU is not the bottleneck at those settings.

How This Combo Ranks

The combination of the AMD Ryzen 7 5700X3D and AMD Radeon RX 6750 XT ranks 922nd out of 1,795 tested combos in Microsoft Flight Simulator. This places it just above the median, indicating that while it is not a top-tier setup, it is far from the bottom. The ranking suggests that this pairing is well-matched for the game’s demands, but it does not excel in any particular area. The CPU’s 82nd percentile ranking and the GPU’s 79th percentile ranking are both respectable, but their combined performance in this simulation-heavy title lands them in the middle of the pack.

The data shows that this combo outperforms many lower-tier systems, but it is outclassed by setups with more powerful CPUs or GPUs. For example, the GPU’s nearest rival, the NVIDIA GeForce RTX 3080, is 1.3% faster in average benchmark scores, while the AMD Radeon RX 5600M is 0.2% slower. This tight grouping means that the RX 6750 XT is competitive with other mid-range cards, but it does not offer a significant advantage. The combo’s rank of 922 reflects this balance, as it is neither a standout performer nor a weak link.

Measured FPS Breakdown

At 1920x1080, the system delivers its best performance across all settings. With Low settings, the average FPS is 126.3, which is exceptionally smooth. Medium settings drop to 98.3 FPS, while High settings provide 72 FPS. Ultra settings at 1080p yield 68 FPS, which is still playable but shows a significant drop from Low. The gap between Low and Ultra is 58.3 FPS, indicating that the GPU is heavily taxed by the higher presets.

Moving to 2560x1440, the frame rates decrease across the board. Low settings average 100 FPS, which is a 26.3 FPS drop from 1080p. Medium settings produce 78.7 FPS, while High settings fall to 59.4 FPS. Ultra settings at 1440p average 54.4 FPS, which is below the 60 FPS target. The scaling from 1080p to 1440p shows a consistent 20-25% reduction in FPS across all presets, indicating that the GPU is becoming a more significant bottleneck.

At 3840x2160, the system struggles to maintain high frame rates. Low settings average 72.2 FPS, which is playable, but Medium drops to 56.8 FPS. High settings yield 42.1 FPS, and Ultra settings fall to 39.1 FPS. The drop from 1080p Low to 4K Low is 54.1 FPS, demonstrating the immense load that 4K places on the GPU. The data clearly shows that 4K gaming is only feasible at Low settings, while 1440p and 1080p offer more headroom.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the limiting component in this system. At 1080p Low, the system achieves 126.3 FPS, but at 4K Low, it drops to 72.2 FPS, a reduction of 42.8%. This significant drop indicates that the GPU is the primary bottleneck at higher resolutions. The CPU’s 8 cores and 16 threads are sufficient to feed the GPU at 1080p, but as the pixel count increases, the GPU’s rendering workload becomes the dominant factor.

At 1080p Ultra, the FPS drops to 68, while at 4K Ultra, it falls to 39.1, a 42.5% reduction. This consistent scaling pattern across all settings confirms that the RX 6750 XT is the limiting factor at 4K. The GPU’s 12 GB of VRAM and 432.0 GB/s memory bandwidth are adequate for the game’s textures, but the 13.31 TFLOPS of FP32 performance is not enough to maintain high frame rates at 4K. Conversely, the CPU’s performance remains consistent, as evidenced by the 3dmark 16-thread score of 6,764, which is not a limiting factor at any resolution.

The data suggests that for the best experience, users should play at 1440p or 1080p, as the CPU has enough headroom to support the GPU at these resolutions. At 4K, the system is clearly GPU-bound, and users will need to compromise on settings to achieve playable frame rates.

Settings Recommendations

Based on the measured FPS data, the High preset at 2560x1440 offers the best overall experience. It provides an average FPS of 59.4, which is just below the 60 FPS target but still smooth enough for a flight simulator. This preset balances visual fidelity with performance, delivering a more immersive experience than Medium without the steep performance cost of Ultra. At 1080p, the High preset achieves 72 FPS, making it an excellent choice for users with 1080p monitors.

For users with 4K displays, the Low preset is the only viable option, as it averages 72.2 FPS. The Medium preset at 4K drops to 56.8 FPS, which is borderline playable, but High and Ultra fall below 45 FPS. The data shows that the Ultra preset is not recommended at any resolution, as it only provides 68 FPS at 1080p and drops to 39.1 FPS at 4K. The performance cost of Ultra is not justified by the visual improvements, especially when High offers a significant FPS advantage.

At 1440p, the Medium preset provides 78.7 FPS, which is a good middle ground for users who prefer higher frame rates over maximum visual quality. However, the High preset’s 59.4 FPS is still acceptable and offers better graphical fidelity. The recommendation is to use High at 1080p or 1440p, and Low at 4K, as these settings provide the best balance of performance and visual quality based on the measured data.

GPU Role

The AMD Radeon RX 6750 XT is a RDNA 2.0 architecture GPU with a base clock of 2150 MHz and a boost clock of 2600 MHz. It features 12 GB of GDDR6 memory on a 192-bit bus, providing 432.0 GB/s of memory bandwidth. The GPU has 2,560 shading units, 160 TMUs, and 64 ROPs, with a pixel rate of 166.4 GPixel/s and a texture rate of 416.0 GTexel/s. The GPU’s FP32 performance is 13.31 TFLOPS, which is competitive for its class.

In Microsoft Flight Simulator, the GPU’s role is to render the complex terrain, aircraft models, and weather effects. The 12 GB of VRAM is sufficient for all tested settings, as the game does not exceed this capacity even at 4K Ultra. The GPU’s 79th percentile ranking among all GPUs indicates that it is a solid mid-range performer, but it struggles at 4K due to the high pixel count. The nearest rival, the NVIDIA GeForce RTX 3080, is 1.3% faster in average benchmark scores, showing that the RX 6750 XT is slightly behind the previous generation’s high-end cards.

The GPU’s performance is most evident at 1080p and 1440p, where it can maintain high frame rates at Medium and High settings. The data shows that the GPU is the limiting factor at 4K, as the FPS drops significantly regardless of CPU performance. The RX 6750 XT’s 13.31 TFLOPS of compute power is not enough to handle 4K Ultra in this simulation, but it excels at lower resolutions, making it a good choice for users with 1080p or 1440p monitors.
