# Resolution Scaling

The measured frame rates for Microsoft Flight Simulator with the AMD Ryzen 5 2600 and AMD Radeon RX 6750 XT reveal a clear pattern of scaling as resolution increases. At 1920x1080 with Low settings, the combo delivers 116.9 FPS, which drops to 102.6 FPS at 2560x1440 and further to 71.6 FPS at 3840x2160. This represents a 38.7% reduction from 1080p to 4K at Low settings, indicating that the GPU is the primary scaling factor at lower quality presets.

The scaling behavior changes character when moving to higher settings. At Ultra settings, the average frame rates are 72.7 FPS at 1080p, 54.7 FPS at 1440p, and 39.6 FPS at 4K. The percentage drop from 1080p to 4K at Ultra is 45.5%, which is steeper than the drop at Low. This suggests that at Ultra settings, both the CPU and GPU are being taxed more heavily, and the resolution scaling amplifies the load on the graphics pipeline.

High settings show a similar trend with 73.5 FPS at 1080p, 57.8 FPS at 1440p, and 41.9 FPS at 4K. The 4K figure at High is only 2.3 FPS higher than the Ultra 4K result, indicating diminishing returns from lowering settings at this resolution. Medium settings produce 96.8 FPS at 1080p, 80.7 FPS at 1440p, and 59.3 FPS at 4K, with the 4K result staying above 60 FPS but not by a wide margin.

The data shows that the limiting component shifts with resolution. At 1080p, the CPU's single-thread performance becomes more relevant, as the frame rates at Low (116.9 FPS) approach what the Ryzen 5 2600 can feed. At 4K, the GPU's workload dominates, and the RX 6750 XT's 12 GB of VRAM and 432.0 GB/s bandwidth are sufficient to maintain playable frame rates across all settings, though Ultra dips to 39.6 FPS. The scaling from 1440p to 4K at High settings (57.8 to 41.9 FPS) is a 27.5% drop, which is expected for a flight simulator with dense scenery rendering.

# GPU Role

The AMD Radeon RX 6750 XT operates with a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz. These clock speeds, combined with 2560 shading units and 64 ROPs, drive the pixel rate of 166.4 GPixel/s and texture rate of 416.0 GTexel/s. The GPU's 12 GB of GDDR6 memory on a 192-bit bus provides 432.0 GB/s of bandwidth, which is critical for Microsoft Flight Simulator's streaming of high-resolution terrain and aircraft textures.

The GPU's role in the measured results is most evident when comparing Low to Ultra settings at the same resolution. At 1080p, Low yields 116.9 FPS while Ultra yields 72.7 FPS, a 44.2 FPS gap that reflects the increased shading and texture work. At 4K, the same settings comparison shows 71.6 FPS versus 39.6 FPS, a 32.0 FPS gap. The smaller absolute gap at 4K suggests that the GPU is nearing its throughput limits, and additional settings headroom is compressed.

The RX 6750 XT's percentile ranking of 79 against all GPUs places it above the median, and its nearest rival comparisons show a deltaPct of -1.3 against the NVIDIA GeForce RTX 3080, meaning it trails by that margin in average benchmark score. The GPU's FP32 throughput of 13.31 TFLOPS and FP16 of 26.62 TFLOPS (2:1) indicate strong compute capability for a mid-range card, but the flight simulator's draw call overhead and CPU dependency at lower resolutions temper these advantages.

In terms of VRAM utilization, the 12 GB capacity is not a bottleneck in the measured rows, as even at 4K Ultra the frame rate remains playable at 39.6 FPS. The memory clock of 2250 MHz (18 Gbps effective) supports the bandwidth figure, and the 192-bit bus width is sufficient for this workload. The GPU's DirectX 12 Ultimate support (12_2) aligns with the game's modern rendering requirements.

# How This Combo Ranks

The combination of the AMD Ryzen 5 2600 and AMD Radeon RX 6750 XT ranks 919 out of 1795 tested combos in Microsoft Flight Simulator. This places the combo in the 51.2 percentile, meaning roughly half of all tested configurations perform better. The CPU's percentile rank of 77 among all CPUs and the GPU's rank of 79 among all GPUs suggest that both components are above average individually, but the pairing does not boost the overall game-specific ranking dramatically.

The CPU's nearest rivals in average benchmark score include the Intel Core i5-1345U at 19691 (deltaPct -0.4), the AMD Ryzen 5 7530U at 19508 (deltaPct 0.6), and the Intel Core i7-10700F at 19485 (deltaPct 0.7). These margins are within 1%, indicating that the Ryzen 5 2600's compute performance is competitive with newer mobile and desktop parts, despite its older Zen architecture. The GPU's nearest rivals show a similar clustering, with the RX 5600M at 35264 (deltaPct 0.2), RTX 5070 Ti Mobile at 35435 (deltaPct -0.3), and RTX 3080 at 35787 (deltaPct -1.3).

The combo's rank of 919 suggests that while the components are balanced, the flight simulator's specific demands—heavy single-thread CPU usage and moderate GPU load—do not favor this pairing as strongly as synthetic benchmarks might indicate. The measured FPS data shows that at 1080p Low, the combo achieves 116.9 FPS, which is competitive, but at 4K Ultra it drops to 39.6 FPS, which is below the average for top-tier combos. The rank reflects this middle-tier performance.

# Settings Recommendations

Based on the measured rows, the optimal settings depend on the target resolution and desired frame rate. At 1920x1080, Medium settings yield 96.8 FPS, which is smooth for a flight simulator, while High provides 73.5 FPS and Ultra 72.7 FPS. The difference between High and Ultra at 1080p is only 0.8 FPS, making Ultra the better choice for visual fidelity without a meaningful FPS penalty.

At 2560x1440, Medium at 80.7 FPS is the best balance, as High drops to 57.8 FPS and Ultra to 54.7 FPS. The step from Medium to High costs 22.9 FPS, which is substantial, so Medium is recommended for 1440p to maintain a smooth experience. Low at 102.6 FPS is available for users prioritizing frame rate over visuals.

At 3840x2160, Medium at 59.3 FPS is the only setting above 60 FPS, but the margin is thin. High at 41.9 FPS and Ultra at 39.6 FPS are within 2.3 FPS of each other, so Ultra is the better visual choice if the user can tolerate sub-40 FPS. Low at 71.6 FPS provides a comfortable margin above 60 FPS for 4K users who prefer performance over quality.

The data indicates that the RX 6750 XT's 12 GB VRAM is not a constraint, as even Ultra settings at 4K do not cause a disproportionate drop relative to High. The recommended preset for most users would be Medium at 1440p or Ultra at 1080p, depending on the monitor's native resolution.

# Measured FPS Breakdown

At 1920x1080, the average FPS values are as follows: Low at 116.9, Medium at 96.8, High at 73.5, and Ultra at 72.7.
