Microsoft Flight Simulator

# Microsoft Flight Simulator — AMD Ryzen 9 5950X + AMD Radeon RX 6800 XT

This combination pairs a 16-core Zen 3 flagship with a RDNA 2 upper-midrange card, and the measured results show a system that is clearly playable across all tested settings, though it leans on the GPU more than the CPU at higher resolutions. The Ryzen 9 5950X, with its 16 cores and 32 threads, sits in the 93rd percentile among all CPUs, while the RX 6800 XT, with 16 GB of GDDR6 and a 256-bit bus, lands in the 87th percentile among GPUs. In Microsoft Flight Simulator, this translates to a setup where 1080p and 1440p are comfortable, 4K requires some settings discipline, and the Ultra preset consistently demands the most from the hardware.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but predictable, and the pattern reveals where the bottleneck shifts. At Low settings, the average frame rate falls from 152.4 FPS at 1920x1080 to 89.5 FPS at 3840x2160 — that is a 41.3% reduction, which is substantial but still leaves the game well above 60 FPS at 4K. The same resolution jump at Medium settings drops from 116.7 FPS to 69.4 FPS, a 40.5% decline, keeping 4K just above the 60 FPS threshold. High settings show a similar trend: 89.6 FPS at 1080p down to 52.6 FPS at 4K, a 41.3% loss that pushes 4K below the smooth-playability line. Ultra is the hardest case, falling from 82.4 FPS at 1080p to 50.7 FPS at 4K, a 38.5% drop.

The consistency of these percentage drops — all between 38% and 41% — indicates that resolution scaling is largely uniform across presets. This uniformity suggests the RX 6800 XT is the primary limiter at higher resolutions, because if the CPU were constraining performance, the gap between 1080p and 4K would narrow significantly at lower settings. Instead, the 1080p Low result of 152.4 FPS shows headroom, but the 4K Ultra result of 50.7 FPS shows the GPU running out of pixel-pushing capacity. At 1440p, the middle ground is solid: Low hits 123.7 FPS, Medium 96.9 FPS, High 71.6 FPS, and Ultra 67.1 FPS, making 1440p the sweet spot for this pairing.

GPU Role

The Radeon RX 6800 XT brings 16 GB of GDDR6 memory on a 256-bit bus, delivering 512.0 GB/s of bandwidth, which is ample for Flight Simulator's large texture loads and streaming terrain data. The card's boost clock of 2250 MHz, with a game clock of 2015 MHz, helps maintain consistent frame times, and the 72 ray accelerators are present but largely idle in this title, as the measured results show no ray tracing-specific data. The GPU's 4608 shading units and 128 ROPs handle the rasterization workload, and the 20.74 TFLOPS FP32 throughput is what drives the high FPS numbers at 1080p and 1440p.

The 16 GB VRAM is particularly relevant for 4K Ultra, where texture detail and draw distances can consume memory quickly. While the data does not show VRAM usage, the fact that 4K Ultra still holds at 50.7 FPS suggests the 16 GB buffer is sufficient for this game's demands at the tested settings. The GPU's percentile ranking of 87 places it near the top tier, and its nearest rival — the NVIDIA GeForce RTX 4070 Ti SUPER — scores 2.6% lower on average, while the Intel Arc A550M scores 0.5% higher. In practice, this means the RX 6800 XT is a strong match for the 5950X, though the CPU's 93rd percentile ranking indicates it has more headroom than the GPU in this pairing.

Settings Recommendations

For 4K displays, the data makes a clear case for Medium settings. The 4K Medium result of 69.4 FPS is comfortably above the 60 FPS target, while High dips to 52.6 FPS and Ultra falls to 50.7 FPS. Low at 4K hits 89.5 FPS, but the visual compromise is likely too severe for a flight simulator where terrain detail matters. At 1440p, High at 71.6 FPS is the recommended balance, as it stays above 60 FPS while offering better visuals than Medium's 96.9 FPS or Low's 123.7 FPS. Ultra at 1440p just misses the mark at 67.1 FPS, so it is playable but not ideal for fluid camera pans.

At 1080p, Ultra at 82.4 FPS is the standout choice, as it delivers the best visual quality while still exceeding 60 FPS by a healthy margin. High at 89.6 FPS and Medium at 116.7 FPS are also viable, but Ultra is the only preset that fully exploits the GPU's capability at this resolution without sacrificing smoothness. The overall guidance is: use Medium for 4K, High for 1440p, and Ultra for 1080p. This matches the measured rows precisely and avoids the 50 FPS range that appears in multiple 4K presets.

Measured FPS Breakdown

At 3840x2160, the RX 6800 XT delivers an average of 89.5 FPS on Low, 69.4 FPS on Medium, 52.6 FPS on High, and 50.7 FPS on Ultra. The gap between Low and Ultra is 38.8 FPS, showing the full range of settings impact at 4K. Medium is the only preset that clears 60 FPS, and it does so with a 16.8 FPS margin over High.

At 2560x1440, the numbers scale up noticeably: Low averages 123.7 FPS, Medium 96.9 FPS, High 71.6 FPS, and Ultra 67.1 FPS. The difference between High and Ultra is just 4.5 FPS, which is surprisingly small and suggests that the Ultra preset's additional effects are not heavily taxing the GPU at this resolution. Low at 1440p is over 120 FPS, which would suit a high-refresh-rate monitor if visual fidelity is secondary.

At 1920x1080, the results are uniformly strong: Low hits 152.4 FPS, Medium 116.7 FPS, High 89.6 FPS, and Ultra 82.4 FPS. The drop from Low to Ultra is 70 FPS, the largest absolute spread across all resolutions, indicating that 1080p is where the CPU's 16 cores can feed the GPU fast enough to expose the full performance range. The 5950X's Cinebench R23 multi-core score of 38607 and single-core score of 5450 support this, as Flight Simulator benefits from strong single-thread performance for its simulation logic.

How This Combo Ranks

This specific combination ranks 615th out of 1795 tested combos in Microsoft Flight Simulator, placing it in the top 34.3% of all pairings. That rank reflects the GPU's 87th percentile standing more than the CPU's 93rd percentile, meaning the RX 6800 XT is the limiting factor in this pairing. The CPU's nearest rivals — the Intel Core i5-14600K at 0.2% lower average score and the Intel Core i5-14600KF at 0.6% lower — show that the 5950X is competitive with modern mid-range CPUs in synthetic benchmarks, but those scores do not directly translate to Flight Simulator FPS, which is more GPU-bound. The GPU's nearest rival, the NVIDIA GeForce RTX 4070 Ti SUPER, scores 2.6% lower on average, suggesting that this AMD card holds its own against a well-regarded NVIDIA option.

The rank of 615 is respectable but not top-tier, and the data supports this: at 4K Ultra the combo manages 50.7 FPS, which is below the 60 FPS threshold that many builders target for a smooth experience. At 1440p Ultra, the 67.1 FPS result is more aligned with a high-refresh experience, and at 1080p Ultra, the 82.4 FPS result is strong. The rank reflects a system that is capable but not overkill for this game, and the 1795-combo pool includes many higher-end GPU pairings that would push 4K Ultra past 60 FPS.

FAQ

Q: Can this combo run Microsoft Flight Simulator at 4K with playable frame rates?

A: Yes, but only on Medium settings, which average 69.4 FPS at 3840x2160. High and Ultra fall below 60 FPS, at 52.6 and 50.7 FPS respectively.

Q: What is the best preset for 1440p gaming with this hardware?

A: High settings at 2560x1440 deliver 71.6 FPS, which is above the 60 FPS target. Ultra is close at 67.1 FPS, but High offers a safer margin for demanding scenes.

Q: How much performance is lost when moving from 1080p to 4K at the same settings?

A: The loss is consistent across presets: Low drops from 152.4 to 89.5 FPS, Medium from 116.7 to 69.4 FPS, High from 89.6 to 52.6 FPS, and Ultra from 82.4 to 50.7 FPS — a roughly 40% reduction in each case.

Q: Is the CPU or GPU the bottleneck in this pairing?

A: The GPU is the limiting factor. The RX 6800 XT ranks in the 87th percentile among GPUs, while the Ryzen 9 5950X ranks in the 93rd percentile among CPUs, and the uniform FPS scaling across resolutions confirms the GPU is the constraint.

Q: How does this combo rank compared to other tested systems in this game?

A: It ranks 615th out of 1795 combos, placing it in the top 34.3% of all pairings tested for Microsoft Flight Simulator.

Q: Does the 16 GB VRAM on the RX 6800 XT help at 4K Ultra settings?

A: The 4K Ultra result of 50.7 FPS suggests the memory buffer is sufficient, as the game remains playable even if below 60 FPS. The 512.0 GB/s bandwidth also supports high-resolution texture streaming without stutter.
