Microsoft Flight Simulator

Microsoft Flight Simulator with an AMD Ryzen 5 3600 and AMD Radeon RX 9070 XT presents a clear case of GPU-driven scaling, where the powerful RDNA 4 card dominates the frame rate curve across resolutions and settings. The data shows this combo ranks 523rd out of 1795 tested combinations, placing it in the top third of all systems, though its behavior at different resolutions reveals distinct performance characteristics worth analyzing.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial but not uniform across settings, indicating where the bottleneck shifts. At Low settings, the average FPS falls from 137 at 1920x1080 to 95.7 at 3840x2160 — a 30% reduction. This relatively modest decline suggests the CPU is still contributing meaningfully at lower graphical loads. The RX 9070 XT’s 16 GB of GDDR6 memory and 644.6 GB/s bandwidth prevent memory capacity from becoming a limiting factor even at 4K.

The scaling pattern changes dramatically at higher settings. At High settings, the drop from 96.8 FPS at 1080p to 75.3 at 1440p to 54.2 at 4K represents a 44% total reduction from 1080p to 4K. The Ultra preset shows similar behavior: 93.9 FPS at 1080p falls to 75.1 at 1440p and 55.8 at 4K — a 41% decrease. This steeper decline at higher presets indicates the GPU becomes the primary constraint as pixel count and graphical complexity rise.

Interestingly, the gap between 1440p and 4K is larger than between 1080p and 1440p for most settings. At Medium, the 1440p score of 100.1 FPS drops to 72.5 at 4K — a 27.6% loss — while moving from 1080p (125.4 FPS) to 1440p costs only 20.2%. This nonlinear scaling suggests that at 4K, the RX 9070 XT is fully saturated by the pixel workload, while at lower resolutions the Ryzen 5 3600’s six cores and twelve threads can still keep pace.

FAQ

Q: Does this combo achieve playable frame rates at 4K Ultra?

A: At 3840x2160 with Ultra settings, the average FPS is 55.8, which is above the 54.2 FPS seen at 4K High. Both presets deliver playable performance, though the difference between them is minimal at this resolution.

Q: What is the best resolution for maximum frame rates?

A: At 1920x1080 with Low settings, the combo reaches 137 FPS, the highest measured result. Even at 1080p Ultra, the average stays at 93.9 FPS, indicating that the system can push high refresh rates at this resolution.

Q: How much performance is lost when moving from 1080p to 1440p?

A: The loss varies by preset. At Low, the drop is from 137 to 127 FPS (7.3% loss). At High, it falls from 96.8 to 75.3 FPS (22.2% loss). The Ultra preset loses 20% (93.9 to 75.1 FPS).

Q: Is the RX 9070 XT fully utilized at 1080p?

A: The data suggests not fully, since Low settings at 1080p produce 137 FPS versus 127 at 1440p Low — only an 8% difference. The smaller resolution gap at Low settings compared to higher presets indicates CPU limiting is present at 1080p.

Q: Which setting preset provides the most balanced experience at 1440p?

A: Medium at 2560x1440 delivers 100.1 FPS, while High and Ultra both hover around 75 FPS. Medium offers a substantial frame rate advantage over the higher presets with only a moderate visual compromise.

Q: How does the RX 9070 XT compare to its nearest rivals in synthetic benchmarks?

A: The GPU’s average benchmark score is 39647, with the closest rival being the AMD Radeon Pro 575 at 39703 (deltaPct of -0.1%). The NVIDIA RTX A500 Mobile scores 39568, showing a 0.2% delta. These differences are negligible in real-world terms.

CPU Role

The AMD Ryzen 5 3600 provides six physical cores and twelve threads based on the Zen 2 architecture, running at a base clock of 3.60 GHz and boost of 4.20 GHz. Its 32 MB shared L3 cache and dual-channel DDR4 memory support at 51.2 GB/s are adequate for feeding a high-end GPU in most scenarios, but the benchmark results indicate this CPU becomes a limiting factor at lower resolutions.

The CPU’s 3DMark scores show a clear scaling pattern: 1361 for 2 threads, 2579 for 4 threads, 3844 for 8 threads, and 4605 for 16 threads. This near-linear scaling with thread count suggests the twelve threads are effectively utilized. In Cinebench R23, the multicore score of 15045 versus single-core of 2124 shows a 7.1x multiplier, indicating strong multithreaded performance for its class.

In Microsoft Flight Simulator, the CPU’s role becomes evident when comparing 1080p Low (137 FPS) to 1440p Low (127 FPS). The small 8% difference suggests the CPU is near its limit at 1080p, unable to push beyond 137 FPS regardless of GPU headroom. The Ryzen 5 3600’s percentile ranking of 76 among all CPUs, with an average benchmark score of 18129, places it just behind the Intel Core i5-11400 (18150, deltaPct -0.1%) and slightly ahead of the AMD Ryzen 5 7535HS (18101, deltaPct 0.2%).

Measured FPS Breakdown

At 1920x1080, the system delivers 137 FPS on Low, 125.4 FPS on Medium, 96.8 FPS on High, and 93.9 FPS on Ultra. The jump from Low to Medium costs only 11.6 FPS (8.5% loss), while moving from Medium to High costs 28.6 FPS (22.8% loss). The High to Ultra transition is minimal at 2.9 FPS (3% loss).

At 2560x1440, results are 127 FPS on Low, 100.1 FPS on Medium, 75.3 FPS on High, and 75.1 FPS on Ultra. The Medium to High drop of 24.8 FPS (24.8% loss) is the steepest transition at this resolution. Notably, High and Ultra produce nearly identical averages, differing by only 0.2 FPS.

At 3840x2160, the scores are 95.7 FPS on Low, 72.5 FPS on Medium, 54.2 FPS on High, and 55.8 FPS on Ultra. Interestingly, Ultra outperforms High by 1.6 FPS at 4K, suggesting measurement variance or that the Ultra preset’s additional features do not add meaningful GPU load in this title. The Low to Medium drop at 4K is 23.2 FPS (24.2% loss), consistent with the 1440p pattern.

GPU Role

The AMD Radeon RX 9070 XT is built on the RDNA 4.0 architecture with 4096 shading units, 256 TMUs, and 128 ROPs. Its 16 GB of GDDR6 memory operates at 2518 MHz (20.1 Gbps effective) across a 256-bit bus, yielding 644.6 GB/s of bandwidth. The boost clock of 2970 MHz and game clock of 2400 MHz drive a theoretical FP32 throughput of 48.66 TFLOPS.

The GPU’s benchmark data shows strong compute potential: 160317 in Geekbench OpenCL and 184026 in Vulkan. In 3DMark Steel Nomad DX12, it scores 7260. The passmark G3D score of 26795 and GPU compute score of 15864 confirm its position in the 82nd percentile among all GPUs, with an average benchmark score of 39647.

In this game, the GPU’s role is dominant at higher resolutions and presets. The 4K Ultra result of 55.8 FPS versus 4K High at 54.2 FPS shows the GPU handles the Ultra preset’s additional load without penalty. At 1440p, the GPU is capable of pushing well above 100 FPS on Medium (100.1 FPS) but the High and Ultra presets both land near 75 FPS, suggesting the RX 9070 XT’s performance ceiling in this title is around 75 FPS at 1440p with high graphical fidelity.

Settings Recommendations

For users prioritizing smoothness at 1080p, the Low preset delivers 137 FPS, which is ideal for high-refresh displays. However, the Medium preset at 125.4 FPS provides a better balance, offering improved visuals for only an 8.5% frame rate reduction. The High preset at 96.8 FPS is still excellent, but the Ultra preset’s 93.9 FPS gain over High is marginal.

At 1440p, the Medium preset stands out with 100.1 FPS, providing the best combination of visual quality and frame rate. The High and Ultra presets both deliver approximately 75 FPS, which is playable but represents a 25% reduction from Medium. Given that High and Ultra are virtually identical in performance, users choosing between them should select Ultra for the visual upgrade at no measurable cost.

At 4K, the Low preset achieves 95.7 FPS, but this compromises visual fidelity significantly. The Medium preset at 72.5 FPS is the sweet spot, offering solid playability. The High and Ultra presets both deliver around 55 FPS, which is borderline for smooth gameplay. Given that Ultra (55.8 FPS) outperforms High (54.2 FPS), there is no reason to choose High over Ultra at this resolution.
