# Microsoft Flight Simulator with AMD Ryzen 7 7700X + AMD Radeon RX 6800 XT

The measured frame rates for this AMD Ryzen 7 7700X paired with the AMD Radeon RX 6800 XT reveal a system that handles Microsoft Flight Simulator with clear headroom at lower resolutions but becomes increasingly GPU-bound as pixel count rises. Across the twelve measured data points, the average FPS ranges from 150.7 at 1080p Low down to 48.4 at 4K Ultra, a spread that shows both the strength of the CPU and the limits of the GPU under maximum load. The data indicates this combination is well-balanced for high-refresh 1080p play, solid for 1440p, and capable but not overwhelming at 4K.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and follows an expected pattern, but the magnitude varies significantly by settings preset. At Low settings, the system delivers 150.7 FPS at 1920x1080, falls to 122.2 FPS at 2560x1440, and then drops to 87.2 FPS at 3840x2160. That represents a 42% reduction from 1080p to 4K at Low, indicating the GPU is still managing the workload without severe bottlenecking. At Ultra settings, the progression is steeper: 83.9 FPS at 1080p, 65.9 FPS at 1440p, and 48.4 FPS at 4K — a 42% drop from 1080p to 4K as well, though the absolute values are much lower.

The High preset shows a similar pattern with 90.0 FPS at 1080p, 74.1 FPS at 1440p, and 53.7 FPS at 4K. Medium settings produce 120.6 FPS at 1080p, 95.0 FPS at 1440p, and 67.6 FPS at 4K. The consistency of the percentage drop across presets — roughly 40-45% from 1080p to 4K — suggests the scaling is primarily driven by pixel count rather than any specific setting. However, the absolute gap between Low and Ultra widens as resolution increases: at 1080p the difference is 66.8 FPS, while at 4K it shrinks to 38.8 FPS. This narrowing indicates that at 4K, the GPU becomes the limiting factor regardless of preset, whereas at 1080p the CPU has enough headroom to let the graphics card stretch its legs.

For a flight simulator where smooth panning over terrain matters, the 1440p results are particularly telling. At High settings, 74.1 FPS is comfortably playable, and at Medium the 95.0 FPS figure provides a noticeable smoothness improvement. The 4K Ultra result of 48.4 FPS is below the 60 FPS threshold many users target, suggesting that users with 4K displays will need to compromise on settings to achieve fluid motion.

Settings Recommendations

The measured data offers a clear hierarchy of presets, and the choice depends heavily on the target resolution. At 1920x1080, all four presets exceed 80 FPS, with Low hitting 150.7 FPS, Medium at 120.6 FPS, and High at 90.0 FPS. Even Ultra manages 83.9 FPS, which is perfectly playable. For 1080p users, Ultra is the obvious recommendation since it provides the best visual quality while still staying well above 60 FPS.

At 2560x1440, the picture changes slightly. Ultra drops to 65.9 FPS, which is acceptable but leaves little margin for demanding scenes. High at 74.1 FPS offers a better balance, while Medium at 95.0 FPS gives substantial headroom. For users with 144Hz or higher refresh monitors, Medium provides the smoothest experience without sacrificing too much visual fidelity. Low at 122.2 FPS is an option for competitive play, but flight simulators rarely require such high frame rates.

At 3840x2160, the recommendations become more constrained. Ultra delivers 48.4 FPS, which is borderline for a sim where smoothness is critical. High at 53.7 FPS is marginally better, but Medium at 67.6 FPS is the first preset that clears the 60 FPS bar comfortably. Low at 87.2 FPS offers the best performance but with significant visual compromises. The data suggests that 4K users should start at Medium and adjust upward only if they can tolerate lower frame rates, or downward if they prioritize smoothness over detail.

GPU Role

The AMD Radeon RX 6800 XT is built on the RDNA 2.0 architecture with a 7 nm process from TSMC, packing 26,800 million transistors into a 520 mm² die. Its 16 GB of GDDR6 memory runs across a 256-bit bus, yielding 512.0 GB/s of bandwidth. The boost clock reaches 2250 MHz, with a game clock of 2015 MHz and a base of 1825 MHz. The GPU has 4608 shading units, 288 texture mapping units, and 128 render output units, resulting in a pixel rate of 288.0 GPixel/s and a texture rate of 648.0 GTexel/s. FP32 performance is rated at 20.74 TFLOPS.

In the context of Microsoft Flight Simulator, the 16 GB VRAM capacity is a notable asset. Flight simulators often load large texture sets for terrain and aircraft, and the measured performance at 4K Ultra — where the GPU is clearly the bottleneck — suggests the memory subsystem is not the limiting factor. The 512.0 GB/s bandwidth provides ample throughput for the data-heavy scenes typical of this genre. The GPU's percentile ranking against all GPUs is 87, and its average benchmark score of 49982 places it near the NVIDIA GeForce RTX 4070 Ti SUPER, which scores 48704 with a deltaPct of 2.6% in the GPU's favor.

The fact that this GPU holds up reasonably well at 4K Medium (67.6 FPS) indicates that its compute resources are sufficient for the game's rendering demands, but the step to Ultra at 4K pushes it below 50 FPS. This aligns with the GPU being an upper-midrange part that can handle high resolutions when settings are moderated.

How This Combo Ranks

The combo rank of 621 out of 1795 tested combinations places this system in the 65th percentile, meaning roughly one-third of tested combos perform better in Microsoft Flight Simulator. This is a solid position for a mid-to-high-end pairing from the previous generation. The CPU, AMD Ryzen 7 7700X, holds an 89th percentile ranking against all CPUs, while the GPU sits at the 87th percentile against all GPUs. The slight gap between the component percentiles and the combo rank suggests that the game's performance is influenced by factors beyond raw compute, such as specific driver optimizations or simulation engine behavior.

The CPU's nearest rivals in synthetic benchmarks help contextualize its contribution. The Intel Core i5-13500 scores 34175, a 0.4% difference, while the Intel Core Ultra 7 165H scores 34584, which is 0.8% higher. These are effectively performance equivalents, meaning the 7700X is not providing any exceptional advantage over its direct competitors in this game. Similarly, the GPU's nearest rivals are within 2.6% of its average benchmark score, reinforcing that this combo is not an outlier in either direction.

CPU Role

The AMD Ryzen 7 7700X is an 8-core, 16-thread processor from the Zen 4 architecture, codenamed Raphael, built on a 5 nm process at TSMC. It features a base clock of 4.50 GHz and a boost clock of 5.40 GHz, with 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. The CPU supports DDR5 memory in a dual-channel configuration with 83.2 GB/s of bandwidth, and it has an integrated Radeon Graphics solution, though this game relies on the discrete GPU.

In Microsoft Flight Simulator, the CPU's role is significant because the simulation engine handles complex physics and AI calculations. The 7700X's single-thread performance, as measured by a 3dmark_single_thread score of 1090 and a Cinebench R23 single-core score of 4281, indicates strong per-core capability. The multi-threaded scores — 30325 in Cinebench R23 multicore and 15538 in Geekbench multicore — show that the 16 threads provide ample throughput for the game's background tasks.

The measured FPS data shows that at 1080p Low, the system achieves 150.7 FPS, which is likely near the CPU's maximum frame delivery capability for this game. At higher settings, the frame rate drops in proportion to GPU load, indicating the CPU is not the primary bottleneck once settings increase. The CPU's percentile ranking of 89 against all CPUs reflects its strong position, and its nearest rivals in synthetic benchmarks are all within 1% of its average score, confirming that it performs at the expected level for its class. The 105 W TDP and 5 nm process also indicate efficient operation, which helps maintain consistent performance over long flight sessions.
