Microsoft Flight Simulator

The AMD Ryzen 9 9950X3D paired with the NVIDIA GeForce RTX 4070 delivers a consistent 60+ FPS experience at 1080p and 1440p in Microsoft Flight Simulator, but the demanding Ultra preset at 4K drops below the 60 FPS threshold. The data shows a clear pattern where the CPU’s strength (16 cores, 32 threads, 128 MB shared L3 cache) keeps frame rates remarkably stable across resolutions, while the GPU’s 12 GB of GDDR6X memory and 192-bit bus become the primary limiting factor at higher pixel counts.

Resolution Scaling

The measured FPS data reveals how this combination scales from 1080p to 4K. At Low settings, the jump from 1920x1080 (164.5 FPS) to 2560x1440 (131.5 FPS) represents a 20% drop, and then to 3840x2160 (97.9 FPS) another 25.5% drop. This scaling pattern is typical for a flight simulator where the CPU’s single-thread performance (3dmark_single_thread score of 1292) handles the complex flight model and weather calculations, while the GPU’s rasterization workload increases quadratically with pixel count.

At Medium settings, the scaling is steeper: 1080p delivers 127.4 FPS, 1440p drops to 101.6 FPS (20.2% decrease), and 4K falls to 76 FPS (25.2% decrease from 1440p). The High preset shows a similar relative pattern (93.7 → 75.8 → 54.3 FPS), but the absolute drop from 1440p to 4K becomes more pronounced at 28.4%. This suggests that as settings increase, the GPU’s shading units (5888) and texture rate (455.4 GTexel/s) become more saturated, and the 12 GB VRAM buffer starts to feel constrained at 4K with higher-quality textures.

The Ultra preset exhibits the worst scaling: 94.1 FPS at 1080p, 74.6 FPS at 1440p (20.7% drop), and 52.7 FPS at 4K (29.4% drop). The fact that 1080p Ultra (94.1 FPS) is nearly identical to 1080p High (93.7 FPS) indicates the CPU is not the bottleneck at this resolution; the GPU is already working near its limits with the most demanding settings. The 4K Ultra result of 52.7 FPS is the only sub-60 FPS result in the entire dataset, confirming that this combination is best suited for 1440p or lower when using maximum fidelity settings.

GPU Role

The RTX 4070’s specifications directly explain its behavior in Microsoft Flight Simulator. With 12 GB of GDDR6X memory on a 192-bit bus providing 504.2 GB/s bandwidth, the card has sufficient memory for 1080p and 1440p at all settings, but 4K Ultra textures can exceed this capacity. The boost clock of 2475 MHz and base clock of 1920 MHz are relatively modest for the 40-series, yet the card still manages to push 164.5 FPS at 1080p Low, indicating that the simulator’s workload is not purely GPU-bound at lower resolutions.

The GPU’s 46 RT cores and 184 tensor cores are present but largely unused in this title, as Microsoft Flight Simulator is primarily a rasterization-heavy workload. The FP32 performance of 29.15 TFLOPS and pixel rate of 158.4 GPixel/s are the relevant figures here, and they explain why the card can handle 4K Medium (76 FPS) but struggles with 4K Ultra (52.7 FPS). The 200 W TDP with a single 16-pin connector and 550 W suggested PSU indicates this is a mid-range power draw, consistent with its position as a 1080p/1440p-focused card.

The GPU benchmark scores place it in the 81st percentile vs all GPUs, with an average benchmark score of 37283. Its nearest rival, the AMD Radeon RX Vega 56, scores 37507 (a -0.6% delta), while the NVIDIA GeForce MX570 A scores 38008 (-1.9% delta). These deltas are minimal, suggesting the RTX 4070 sits in a competitive performance band, but the flight simulator results show that raw compute scores don’t always translate to FPS in this specific title.

FAQ

Q: Can this combo run Microsoft Flight Simulator at 4K?

A: Yes, but only at Low (97.9 FPS), Medium (76 FPS), or High (54.3 FPS) settings. Ultra at 4K produces 52.7 FPS, which is below the 60 FPS threshold. For consistent 60+ FPS at 4K, stick to Medium settings.

Q: What is the best resolution for this pairing?

A: 2560x1440 is the sweet spot. At Medium settings it delivers 101.6 FPS, at High 75.8 FPS, and even Ultra achieves 74.6 FPS. This resolution allows you to use any preset while maintaining playable frame rates.

Q: Is the CPU or GPU the bottleneck at 1080p?

A: At 1080p, the data shows the GPU becomes the limiting factor above Low settings. The difference between Ultra (94.1 FPS) and High (93.7 FPS) is negligible, suggesting the RTX 4070’s rasterization throughput is saturated. The Ryzen 9 9950X3D with its 5.70 GHz boost clock and 16 cores is not the constraint here.

Q: How does the RTX 4070 compare to its nearest rivals in this game?

A: The GPU’s nearest rival by average benchmark score is the AMD Radeon RX Vega 56, which scores 37507 versus the RTX 4070’s 37283 (-0.6% delta). The NVIDIA GeForce MX570 A scores 38008 (-1.9% delta), while the RTX 4080 Mobile scores 38135 (-2.2% delta). These deltas are all within 2.5%, indicating similar raw performance.

Q: What FPS can I expect at 1440p Ultra?

A: The measured data shows 74.6 FPS at 2560x1440 with Ultra settings. This is comfortably above 60 FPS and provides a smooth experience for a flight simulator, which benefits from consistent frame pacing more than raw FPS.

Q: Does lowering settings from Ultra to High help at 4K?

A: Yes, but marginally. At 4K, High settings yield 54.3 FPS versus 52.7 FPS on Ultra — a 3% improvement that doesn’t cross the 60 FPS line. Dropping to Medium gives 76 FPS, a 44% improvement over Ultra, making it the recommended setting for 4K.

Measured FPS Breakdown

The complete measured dataset for this combination is as follows:

At 1920x1080: Low settings produce 164.5 FPS average, Medium produces 127.4 FPS, High produces 93.7 FPS, and Ultra produces 94.1 FPS. The near-identical High and Ultra results suggest a GPU ceiling around 94 FPS at this resolution.

At 2560x1440: Low settings deliver 131.5 FPS, Medium delivers 101.6 FPS, High delivers 75.8 FPS, and Ultra delivers 74.6 FPS. Again, High and Ultra are nearly identical, confirming the GPU’s rasterization limit is being reached.

At 3840x2160: Low settings achieve 97.9 FPS, Medium achieves 76 FPS, High achieves 54.3 FPS, and Ultra achieves 52.7 FPS. This is the only resolution where High and Ultra both fall below 60 FPS, making 4K viable only with Medium or lower settings.

The pattern across all resolutions is clear: the GPU’s fill rate and memory bandwidth (504.2 GB/s) are the determining factors. The transition from High to Ultra adds minimal FPS cost at 1080p and 1440p, suggesting the Ultra preset’s additional effects are largely CPU-independent, while the 4K drop shows the VRAM capacity and bus width limitations.

How This Combo Ranks

This specific combination of AMD Ryzen 9 9950X3D and NVIDIA GeForce RTX 4070 ranks 455th out of 1795 tested combos in Microsoft Flight Simulator, placing it in the top 25% of all pairings. The CPU itself is in the 96th percentile vs all CPUs with an average benchmark score of 71660, while its nearest rivals include the Intel Xeon Platinum 8270 (71056, 0.9% delta), AMD Ryzen 9 9950X (70420, 1.8% delta), and Intel Core i7-14700KF (70104, 2.2% delta). This indicates the CPU is outperforming many high-end alternatives, which helps explain why the combo ranks as well as it does despite the GPU’s mid-range positioning.

The GPU’s 81st percentile ranking vs all GPUs is respectable but not top-tier, and its nearest rivals are within 2.5% of its average benchmark score. This suggests that pairing this CPU with a stronger GPU would likely improve the combo’s rank significantly, as the CPU has headroom to feed a more powerful graphics card. The 455th rank out of 1795 reflects a well-balanced pairing where the CPU is not the limiting factor in most scenarios, but the GPU holds back 4K Ultra performance.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on your target resolution and preference for visual fidelity. For 1080p displays, Ultra settings provide 94.1 FPS and are the clear choice — the visual upgrade over High costs only 0.4 FPS (94.1 vs 93.7), making it a free improvement. At 1440p, Ultra delivers 74.6 FPS, which is smooth for a flight simulator, so there is no reason to drop below this preset unless you want extra headroom for recording or streaming.

For 4K displays, the recommendation is more nuanced. If you prioritize frame rate, Medium settings at 76 FPS offer the best balance, providing a 40% improvement over High (54.3 FPS) while still maintaining decent visual quality. If you insist on High or Ultra settings at 4K, be prepared for sub-60 FPS performance (54.3 and 52.7 FPS respectively), which is playable but not ideal for a simulator that benefits from smooth panning and camera movements.

The Low preset is only worth considering for competitive or very high-refresh-rate scenarios, as it produces 164.5 FPS at 1080p and 131.5 FPS at 1440p, but it sacrifices the visual fidelity that makes this game immersive. For most users, the data suggests 1440p Ultra (74.6 FPS) as the best overall experience, while 4K Medium (76 FPS) is the fallback for those who prioritize resolution over settings.
