# Microsoft Flight Simulator: AMD Ryzen 5 7500X3D + AMD Radeon RX 6800 XT

The AMD Ryzen 5 7500X3D paired with the AMD Radeon RX 6800 XT delivers a solid, playable experience in Microsoft Flight Simulator, though the data shows a clear pattern of the GPU becoming the primary bottleneck as resolution climbs. At 1080p, the combo produces high frame rates across all settings, but the gap between Low and Ultra presets narrows significantly at 4K, suggesting the CPU has enough headroom to feed the GPU at lower resolutions while the graphics card struggles to maintain pace at higher pixel counts.

Resolution Scaling

The measured FPS data reveals a predictable yet important scaling pattern across the three tested resolutions. At 1080p with Low settings, the combo achieves 153 FPS average, which drops to 123 FPS at 1440p (a 19.6% reduction) and further to 91 FPS at 4K (a 40.5% reduction from 1080p). This scaling is steep, indicating that the RX 6800 XT is the limiting factor as resolution increases, since the CPU has ample headroom at lower resolutions.

Moving to Medium settings, the average FPS goes from 119 at 1080p, to 96 at 1440p (a 19.3% drop), and then to 71 at 4K (a 40.3% drop from 1080p). The consistency of these percentage drops across Low and Medium presets strongly suggests a GPU-bound scenario at higher resolutions. The CPU's 6 cores and 12 threads, with a boost clock of 4.50 GHz, are clearly capable of maintaining frame delivery at these settings, as the frame rate losses track almost exactly with the pixel count increase.

High settings tell a similar story: 90 FPS at 1080p, 72 FPS at 1440p (20% drop), and 53 FPS at 4K (41.1% drop). At Ultra settings, the pattern holds with 85 FPS at 1080p, 69 FPS at 1440p (18.8% drop), and 51 FPS at 4K (40% drop). The near-identical percentage drops across all four presets—roughly 19-20% from 1080p to 1440p and 40-41% from 1080p to 4K—are a textbook signature of GPU-limited scaling. If the CPU were the constraint, the frame rate drops would be less pronounced at higher resolutions because the CPU workload would remain relatively constant regardless of pixel count.

The 4K Ultra result of 51 FPS average is notably close to the 4K High result of 53 FPS, differing by only 2 FPS. This suggests that at 4K, the GPU is so heavily loaded that the difference between High and Ultra presets has minimal impact on actual frame rates—the card is simply maxed out. At 1080p, however, the gap between High and Ultra is 5 FPS (90 vs 85), showing slightly more headroom for GPU work at lower resolutions.

For users targeting 1440p, the data shows this combo is well-suited. The Medium preset delivers 96 FPS average with a minimum of 82 FPS and maximum of 110 FPS, which is comfortably above the 60 FPS threshold for smooth flight simulation. Even at High settings, 72 FPS average is respectable. At 4K, however, users should expect frame rates in the 51-71 FPS range depending on settings, which is playable but not ideal for fast-moving cockpit views or dense scenery areas.

Settings Recommendations

The measured rows provide a clear hierarchy of performance across presets, and the optimal choice depends heavily on the target resolution. At 1080p, the data shows that even Ultra settings yield 85 FPS average, which is well above the typical 60 FPS target for this genre. The 153 FPS Low preset result is excessive for a flight simulator, where the gameplay is not twitch-reaction based, so there is no practical reason to sacrifice visual quality at this resolution. The Ultra preset at 1080p is the recommended choice, as it provides the best visual fidelity while still maintaining a high frame rate.

At 1440p, the Medium preset stands out as the sweet spot. The data shows 96 FPS average with a minimum of 82 FPS, which ensures smooth performance even during complex scenes with dense terrain or weather effects. The High preset at 72 FPS average is also playable, but the 24 FPS gap between Medium and High (96 vs 72) is substantial, and the visual difference between these presets in Microsoft Flight Simulator is often less noticeable than the frame rate impact. The Ultra preset at 69 FPS average is close to High (72), so if visual quality is the priority, the 3 FPS difference between High and Ultra does not justify the extra GPU load—stick with High if you want the best balance, or Medium if you prioritize frame rate stability.

For 4K, the data presents a more constrained picture. The Medium preset delivers 71 FPS average with a minimum of 60 FPS, which is exactly at the threshold for smooth play. This is the recommended preset for 4K, as it provides the best combination of playability and visual quality. The High preset at 53 FPS average is borderline, and the Ultra preset at 51 FPS average is skirting the edge of comfort—these lower frame rates can lead to noticeable stutter in a flight simulator where smooth camera panning is critical. The Low preset at 91 FPS average is technically the smoothest option, but the visual degradation in a game that relies heavily on scenery detail makes this a poor trade-off for most users.

The minimum FPS data available for Medium settings reinforces the recommendation: at 1080p the minimum is 101 FPS, at 1440p it is 82 FPS, and at 4K it is 60 FPS. These minimums show that the Medium preset maintains a consistent frame rate without significant dips, which is crucial for a simulation game where frame time spikes can cause visual judder. The absence of minimum FPS data for other presets means we cannot fully assess their frame time consistency, but the averages suggest they are likely less stable than Medium.

GPU Role

The AMD Radeon RX 6800 XT, based on the RDNA 2.0 architecture with the Navi 21 chip, plays the dominant role in determining this combo's performance in Microsoft Flight Simulator. The card features 16 GB of GDDR6 memory on a 256-bit bus, providing 512.0 GB/s of memory bandwidth, which is ample for the high-resolution textures commonly used in this game. The 16 GB capacity is particularly relevant for flight simulation, where large photogrammetry areas and high-detail aircraft models can consume significant video memory at 4K resolution.

The GPU's clock speeds are a key factor in its performance. The base clock runs at 1825 MHz, with a game clock of 2015 MHz and a boost clock of 2250 MHz. The boost clock behavior, where the card dynamically increases its frequency under load, is critical for maintaining frame rates in Microsoft Flight Simulator, which tends to have varying GPU loads depending on the scene complexity. The card's 4608 shading units and 128 ROPs provide substantial raw compute throughput, with a pixel rate of 288.0 GPixel/s and a texture rate of 648.0 GTexel/s. These specifications translate to the measured FPS results, where the GPU becomes the clear bottleneck at 4K.

The GPU's benchmark scores place it in the 85th percentile of all GPUs, with an average benchmark score of 48477. Its nearest rivals include the NVIDIA RTX A1000 Mobile (1.5% higher score), the Intel Arc A550M (2.5% lower), and the NVIDIA GeForce RTX 5070 Ti (3% lower). These comparisons show that the RX 6800 XT is competitively positioned in the mid-to-high range, and its performance in Microsoft Flight Simulator reflects this standing. The card's FP32 compute of 20.74 TFLOPS and FP16 of 41.47 TFLOPS provide the processing power needed for the game's complex lighting and shadow calculations.

The 300 W TDP and dual-slot cooling solution suggest this is a power-hungry card, but the measured FPS data shows that this power is put to good use. The 4K Medium result of 71 FPS average with a 60 FPS minimum demonstrates that the card has enough headroom to handle the game's demands at high resolutions, though the gap between Medium and High at 4K (18 FPS difference) indicates that the card is nearing its limits at this resolution.
