# Microsoft Flight Simulator — AMD Ryzen 5 3600 + NVIDIA GeForce RTX 5080

The measured performance data for this combination shows a system that is heavily balanced toward the GPU, with the RTX 5080 delivering strong frame rates across all resolutions while the Ryzen 5 3600's six cores and twelve threads keep pace without becoming the primary constraint in most settings. Across 4K, 1440p, and 1080p, the average FPS ranges from 71.5 to 134, with the spread between Low and Ultra presets revealing a clear pattern: this pairing is capable of smooth flight simulation at high resolutions, but the CPU's Zen 2 architecture becomes more relevant as resolution drops and settings are lowered.

Resolution Scaling

The FPS progression from 1080p to 4K demonstrates classic resolution scaling behavior, with the most significant drops occurring at higher quality presets. At Ultra settings, the average FPS falls from 106.4 at 1920x1080 to 98.9 at 2560x1440, then sharply to 71.5 at 3840x2160 — a 34.9 FPS reduction from 1080p to 4K, representing a 32.8% decrease. This indicates that at Ultra, the GPU is the limiting component at 4K, as the RTX 5080's rendering load quadruples in pixel count.

At Low settings, the scaling is much flatter: 134 FPS at 1080p, 123.8 at 1440p, and 114 at 4K. The total drop from 1080p to 4K is only 20 FPS (14.9%), which suggests that at Low preset, the CPU begins to assert its influence. The Ryzen 5 3600's 3.60 GHz base clock and 4.20 GHz boost clock, combined with its six cores, appear sufficient to maintain frame rates above 114 FPS even at 4K Low, but the smaller gap between resolutions at Low versus High/Ultra implies a growing CPU bottleneck at lower graphical loads.

Medium settings show a similar pattern to High, with 122.1 FPS at 1080p, 116.3 at 1440p, and 103.2 at 4K. High preset produces 114 FPS at 1080p, 102 at 1440p, and 78.2 at 4K. The 4K High result of 78.2 FPS is notably 35.8 FPS below the 4K Low figure, underscoring how much headroom the GPU has when the CPU is less stressed. Benchmarks indicate the RTX 5080 sits at the 89th percentile among all GPUs, while the Ryzen 5 3600 ranks at the 76th percentile among CPUs — a gap that aligns with the observed resolution scaling curve.

Settings Recommendations

For users targeting 60+ FPS at 3840x2160, the data shows that Ultra settings are still viable at 71.5 FPS, though this is the lowest measured average across all configurations. High at 4K delivers 78.2 FPS, a modest 6.7 FPS improvement over Ultra, while Medium jumps to 103.2 FPS and Low reaches 114 FPS. The most efficient preset for 4K appears to be Medium: it provides a 31.7 FPS advantage over Ultra (a 44.3% increase) while only sacrificing visual fidelity compared to High, which is just 25 FPS slower.

At 2560x1440, the picture is different. Ultra achieves 98.9 FPS, High reaches 102, Medium hits 116.3, and Low tops out at 123.8. Here, High is only 3.1 FPS above Ultra, making Ultra the better choice for maximum visual quality with negligible performance cost. The gap between Medium and Low is just 7.5 FPS, indicating diminishing returns from lowering settings further at this resolution.

At 1920x1080, all presets exceed 106 FPS, with Low at 134, Medium at 122.1, High at 114, and Ultra at 106.4. The differences between presets are more pronounced at 1080p: Ultra is 27.6 FPS below Low, and High is 20 FPS below Low. Given that the CPU's single-thread score in 3DMark is 696 and its Cinebench R23 single-core result is 2124, the Ryzen 5 3600 appears to be the limiting factor at 1080p Low, where the GPU has the least work to do. The best experience at 1080p is likely High, as it maintains 114 FPS while offering substantial visual upgrades over Medium's 122.1 FPS.

CPU Role

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor based on the Zen 2 architecture (codenamed Matisse) built on a 7 nm TSMC process. Its 3.60 GHz base clock and 4.20 GHz boost clock are modest by modern standards, and its 32 MB shared L3 cache is typical for the 3000 series. In synthetic benchmarks, the CPU achieves a PassMark multithread score of 17700 and a single-thread score of 2562, with a Cinebench R23 multicore result of 15045 and single-core of 2124. These numbers place it in the 76th percentile of all CPUs, with its nearest rival being the Intel Core i5-11400 at a delta of -0.1% and the AMD Ryzen 5 7535HS at +0.2%.

In Microsoft Flight Simulator, the CPU's role is most evident at lower resolutions and settings. At 1080p Low, the 134 FPS result is only 20 FPS higher than 4K Low's 114 FPS, a 14.9% improvement that is far smaller than the 4x pixel reduction would suggest. This indicates that the CPU is topping out near 134 FPS in this scenario, regardless of how much GPU headroom exists. The RTX 5080's PassMark G3D score of 36565 places it in the 89th percentile, far above the CPU's relative standing, so when settings are lowered, the CPU's six cores become the bottleneck.

The 12 threads help maintain frame pacing in a simulation that can utilize multiple cores for terrain loading and physics calculations. However, the CPU's 3DMark 16-thread score of 4605 and max-thread score of 4603 show that scaling beyond 8 threads yields minimal gains — the 8-thread score is 3844, suggesting diminishing returns that could limit performance in heavily threaded scenes. Flight simulators often have single-threaded bottlenecks for flight model computations, and the Ryzen 5 3600's single-thread performance, while adequate for 60+ FPS at Ultra settings, becomes the ceiling at lower presets.

How This Combo Ranks

This specific combination of AMD Ryzen 5 3600 and NVIDIA GeForce RTX 5080 ranks 271 out of 1795 tested combos in Microsoft Flight Simulator, placing it in the top 15.1% of all systems tested. This rank reflects the balance between a CPU that is above average (76th percentile) and a GPU that is well above average (89th percentile), with the overall combination performing better than the CPU's percentile would suggest alone.

The fact that this combo ranks higher than the CPU's individual percentile indicates that the RTX 5080's performance dominates in this title, which is consistent with the resolution scaling data showing GPU-bound behavior at 4K and higher settings. The 271st rank out of 1795 combos means there are 270 combinations that deliver higher average FPS, likely featuring newer or higher-end CPUs paired with similarly capable GPUs. The Ryzen 5 3600's nearest rivals in terms of average benchmark score — the Intel Core i5-11400 at -0.1% delta and the AMD Ryzen 5 7535HS at +0.2% — are all within 0.3% of its score, suggesting that swapping to any of these would yield nearly identical results in this game.

The RTX 5080's nearest GPU rivals, including the Intel Arc A570M at +1.6% delta and the Intel Arc A580 at +2.5%, are similarly close, but the GPU's absolute performance is what boosts this combo. In practical terms, the 271st rank means this system delivers smooth gameplay across the board, with even the most demanding 4K Ultra setting producing 71.5 FPS, which is well above playable thresholds.

FAQ

Q: What is the highest average FPS this combo achieves in Microsoft Flight Simulator?

A: The highest measured average is 134 FPS, achieved at 1920x1080 with Low settings. The lowest is 71.5 FPS at 3840x2160 with Ultra settings.

Q: Is this system better suited for 4K or 1080p gaming in this title?

A: The data shows strong performance at both resolutions. At 4K Ultra, it maintains 71.5 FPS, which is playable, while at 1080p Low it reaches 134 FPS. However, the CPU becomes a limiting factor at 1080p Low, where the FPS gain over 4K Low is only 20 FPS despite a 4x pixel reduction.

Q: How does the Ryzen 5 3600 compare to its closest rival CPUs?

A: The Ryzen 5 3600's average benchmark score is 18129, placing it within 0.3% of the Intel Core i5-11400 (-0.1% delta), the AMD Ryzen 5 7535HS (+0.2%), and the AMD Ryzen 5 1600 (-0.2%). All four CPUs perform nearly identically in synthetic benchmarks.
