Microsoft Flight Simulator

The AMD Ryzen 5 3600 paired with the NVIDIA GeForce RTX 5070 Ti delivers a robust Microsoft Flight Simulator experience, but the data reveals a clear bottleneck dynamic. The system ranks in the 82nd percentile (316th of 1795 tested combos), indicating strong overall performance. However, the scaling pattern from 1080p to 4K shows that the CPU is the primary limiter at lower resolutions, while the GPU takes over at higher ones. This analysis breaks down the measured FPS data to explain exactly where this combo excels and where it leaves performance on the table.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic, but not uniform across settings. At Low settings, the average frame rate falls from 136.6 FPS at 1920x1080 to 114.6 FPS at 3840x2160 — a 16.1% reduction. This relatively modest decline indicates that at Low settings, even at 4K, the CPU is still the primary constraint. The Ryzen 5 3600's 6 cores and 12 threads are being pushed hard, and the RTX 5070 Ti has ample headroom to spare.

The situation changes at Ultra settings. Here, the average drops from 111.3 FPS at 1080p to 65.5 FPS at 4K — a 41.1% reduction. This steep falloff signals that the GPU is now the limiting factor. The RTX 5070 Ti's 16 GB of GDDR7 memory and 896.0 GB/s bandwidth are being saturated by the combination of 4K resolution and Ultra detail. The gap between Low and Ultra at 4K is 49.1 FPS (114.6 vs 65.5), whereas at 1080p that same gap is just 25.3 FPS (136.6 vs 111.3). This widening gap confirms that resolution scaling places progressively more strain on the GPU.

At 1440p, the system behaves as a middle ground. The Low setting delivers 126.1 FPS, while Ultra drops to 88.6 FPS. The scaling from 1080p to 1440p at Medium settings shows a 6.7% drop (124.6 to 116.2 FPS), which is far less severe than the 25.2% drop seen from 1440p to 4K at the same setting (116.2 to 92.8 FPS). This suggests that 1440p is the sweet spot where neither component is fully overwhelmed, allowing the combo to maintain high frame rates across all presets.

CPU Role

The AMD Ryzen 5 3600 is a Zen 2 (Matisse) part with 6 cores and 12 threads, base clock of 3.60 GHz and boost clock of 4.20 GHz. Its Cinebench R23 multi-core score of 15045 and single-core score of 2124 place it in the 76th percentile against all CPUs. This single-thread performance is crucial for Microsoft Flight Simulator, which relies heavily on a few primary threads for simulation logic and scenery streaming.

The data shows this CPU holds up well at 1080p. At Low settings, the system hits 136.6 FPS, which is the highest measured result in the entire dataset. This indicates that the RTX 5070 Ti is not the bottleneck at this resolution and preset; the frame rate is being capped by what the CPU can feed to the GPU. The 3dmark single-thread score of 696 and 2-thread score of 1361 suggest that the CPU's ability to handle the game's primary threads is adequate for high refresh rates.

However, the CPU's age shows in the scaling pattern. When moving from 1080p Low to 1440p Low, the frame rate only drops from 136.6 to 126.1 FPS (7.7%). But from 1440p Low to 4K Low, the drop is just 9.1% (126.1 to 114.6). This relatively flat scaling at Low settings across resolutions is a classic sign of CPU limitation. The processor is delivering roughly the same work output regardless of resolution, because the GPU is never stressed enough to become the bottleneck. The 3dmark max-thread score of 4603 and 16-thread score of 4605 are nearly identical, showing that the CPU has limited headroom beyond its 12 threads.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is a Blackwell 2.0 architecture part with 8960 shading units, 70 RT cores, and 280 tensor cores. Its boost clock of 2452 MHz and FP32 performance of 43.94 TFLOPS place it in the 87th percentile against all GPUs. The 16 GB of GDDR7 memory on a 256-bit bus delivers 896.0 GB/s of bandwidth, which is critical for a flight simulator that streams vast amounts of terrain and scenery data.

The GPU's dominance becomes evident at 4K Ultra, where the system delivers 65.5 FPS. This is the most demanding scenario in the dataset, and the fact that it stays above 60 FPS reflects the GPU's raw power. The PassMark G3D score of 32974 and 3DMark Steel Nomad DX12 score of 6604 confirm that this is a high-end graphics card. Its nearest rival, the NVIDIA GeForce RTX 4080, has an average benchmark score of 52085 — essentially identical to the RTX 5070 Ti's 52086 (0.0% delta).

The GPU's role is most clearly visible in the difference between Low and Ultra at 4K. The jump from 114.6 FPS to 65.5 FPS represents a 42.9% performance cost for the visual upgrade. This is the GPU flexing its muscles — the card is capable of handling the extra load, but the frame rate penalty is substantial. At 1080p, the same Low-to-Ultra transition only costs 18.5% (136.6 to 111.3 FPS), because the CPU is limiting the maximum achievable frame rate and the GPU has spare capacity.

How This Combo Ranks

The combo ranks 316th out of 1795 tested combinations, placing it in roughly the 82nd percentile of all systems tested. This is a strong result, but it is important to contextualize it against the individual component performance. The CPU sits in the 76th percentile (with an average benchmark score of 18129), while the GPU is in the 87th percentile (average score 52086). The combo ranking is between these two figures, suggesting that the CPU is holding the system back from reaching its full potential.

The CPU's nearest rivals provide context. The Intel Core i5-11400 has an average score of 18150, just a 0.1% delta from the Ryzen 5 3600. The AMD Ryzen 5 7535HS is 0.2% ahead at 18101, while the AMD Ryzen 5 1600 is 0.2% behind at 18158. These are all extremely close scores, meaning the CPU is performing exactly as expected for its class. The GPU's nearest rival, the RTX 4080, is statistically tied at 0.0% delta, confirming that the graphics card is performing at the top of its expected range.

Given that the GPU is tied with the previous generation's flagship-class card and the CPU is a mid-range 2019 part, the data suggests that the combo ranking is being dragged down by the processor. If the CPU were upgraded to a newer, higher-clocked part, the GPU would likely be able to push higher frame rates at 1080p and 1440p, where the CPU is currently the bottleneck.

Settings Recommendations

The data clearly identifies Ultra as the best experience for this combo at 1080p and 1440p. At 1920x1080, Ultra delivers 111.3 FPS, which is only 2.0% lower than High (109.3 FPS) and actually higher than High by 2.0 FPS. This is unusual — the Ultra preset outperforms High at 1080p, likely due to measurement variance, but it means there is no reason to drop below Ultra at this resolution. The 25.3 FPS gap between Ultra (111.3) and Low (136.6) is a worthwhile trade for the significant visual fidelity gains.

At 1440p, Ultra delivers 88.6 FPS, which is comfortably above the 60 FPS threshold for smooth flight simulation. The drop from High (93.9 FPS) to Ultra (88.6 FPS) is just 5.6%, making Ultra the clear choice. The gap between Ultra and Low at 1440p is 37.5 FPS (88.6 vs 126.1), but the visual improvement from Low to Ultra is substantial in a game where cockpit detail and terrain rendering matter.

At 4K, the recommendation shifts. Ultra delivers 65.5 FPS, which is playable but leaves little headroom for complex scenes or add-on aircraft. High delivers 71.9 FPS, a 9.8% improvement over Ultra, while Medium hits 92.8 FPS. For most users, High is the optimal 4K preset — it maintains a comfortable margin above 60 FPS while preserving most of the visual quality. Medium is the safer choice for users who prioritize smoothness, with a 41.7% improvement over Ultra (92.8 vs 65.5 FPS).
