Microsoft Flight Simulator

Microsoft Flight Simulator pairs the AMD Ryzen 9 5900X with the NVIDIA GeForce RTX 3070, a combination that produces a measured data set across three resolutions and four quality presets. The benchmark results show a system that is capable of high frame rates at lower resolutions but becomes increasingly constrained as pixel count and graphical load rise. This analysis examines the recorded FPS to determine the balance between CPU and GPU roles, the impact of resolution scaling, and the optimal settings for this specific hardware pairing.

How This Combo Ranks

The combination of the AMD Ryzen 9 5900X and NVIDIA GeForce RTX 3070 ranks 813 out of 1795 tested combos in Microsoft Flight Simulator. This places it in the 45th percentile of all tested systems, indicating a mid-pack performance tier for this specific title. The ranking reflects that while the CPU is a high performer in synthetic benchmarks, the game's demands on the GPU are significant, and the RTX 3070's capability in this flight simulator is the limiting factor.

The CPU itself, the Ryzen 9 5900X, holds a 90th percentile ranking against all CPUs in the database, with an average benchmark score of 39453. Its nearest rivals include the AMD EPYC 4245P, which scores 39383 (a 0.2% difference), and the Intel Core i7-13700, which scores 39857 (a -1% difference). This suggests the processor is not the bottleneck in this combo; its compute potential is far above what the game's GPU-bound scenarios require at higher settings. The GPU, conversely, sits in the 72nd percentile for all GPUs, with an average score of 28238. Its nearest rival, the AMD Radeon RX 6600 XT, scores 27985, which is a 0.9% delta, showing the RTX 3070's position is tightly clustered with other mid-range cards.

The disparity between the CPU's high percentile (90) and the combo's overall rank (813/1795) indicates that the RTX 3070 holds the combo back from higher placements. In Microsoft Flight Simulator, the data shows that the GPU's performance ceiling is what defines the experience, especially when compared to the CPU's abundant headroom. The combo rank is a product of this imbalance, resulting in a system that is neither top-tier nor entry-level, but rather a solid middle-ground performer.

GPU Role

The NVIDIA GeForce RTX 3070 features 8 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 448.0 GB/s. Its base clock is 1500 MHz with a boost clock of 1725 MHz. These specifications are directly reflected in the measured frame rates, particularly at higher resolutions and settings where memory capacity and bandwidth become critical. The 8 GB frame buffer is a decisive factor; at 4K with Ultra settings, the GPU is likely hitting its memory and compute limits.

The RTX 3070's 5888 shading units and 96 ROPs handle the rasterization load, but the data shows a steep drop-off as settings increase. At 1080p, the GPU delivers 136.6 FPS on Low settings, but this falls to 75.2 FPS on Ultra — a reduction of 45%. At 4K, the same pattern is more severe: Low yields 79.4 FPS, while Ultra drops to 45 FPS. The boost clock of 1725 MHz is not sufficient to overcome the increased shader work at 4K Ultra, where the average FPS falls below the 60 FPS threshold.

The GPU's synthetic benchmark scores corroborate this behavior. Its Passmark G3D score is 22214, and its 3DMark Steel Nomad DX12 score is 3162. These numbers, combined with the measured FPS, indicate that the RTX 3070 is a capable 1080p and 1440p card for this simulator, but its 8 GB VRAM and bandwidth limit its 4K potential. The game's asset streaming at Ultra settings likely saturates the memory bus, leading to the observed performance plateau where High and Ultra settings produce nearly identical results at 4K (45.9 FPS vs 45 FPS).

Resolution Scaling

The measured FPS data reveals a clear pattern of scaling from 1080p to 4K. At 1080p High, the combo produces 77.2 FPS. Moving to 1440p High, the frame rate drops to 61.2 FPS, a 20.7% reduction. At 4K High, the average falls to 45.9 FPS, which is a 40.5% drop from the 1080p figure. This scaling indicates that the GPU is the primary limiting component, as the CPU's performance headroom cannot compensate for the increased pixel count.

The Low settings preset shows the most dramatic scaling. At 1080p Low, the system achieves 136.6 FPS. At 1440p Low, it drops to 108 FPS (a 21% decrease), and at 4K Low, it reaches 79.4 FPS (a 42% decrease from 1080p). This consistent ~20% drop per resolution step suggests a linear relationship with pixel count, which is the hallmark of a GPU-bound scenario. The CPU, with its 12 cores and 24 threads, is not the constraint here; its single-thread score of 941 in 3DMark and Cinebench R23 single-core score of 4680 are more than sufficient for the game's logic.

At Ultra settings, the scaling is less linear. From 1080p Ultra (75.2 FPS) to 1440p Ultra (61.6 FPS), the drop is 18%. But from 1440p to 4K Ultra, the drop is 27% (to 45 FPS). This steeper decline at 4K Ultra points to the 8 GB VRAM limit being exceeded, forcing the GPU to manage memory more aggressively. The data suggests that the RTX 3070 is fully utilized at 4K, and the frame rate is entirely dependent on its compute and memory throughput, not the CPU.

Settings Recommendations

Based on the measured FPS rows, the Medium preset at 1440p offers the best balance of visual fidelity and performance, yielding 86.2 FPS. This is well above the 60 FPS target and provides headroom for demanding scenes. For users prioritizing higher visual quality, the High preset at 1440p delivers 61.2 FPS, which is still playable but with less margin for variability.

At 1080p, the Ultra preset achieves 75.2 FPS, making it a viable option for users with 1080p displays who want maximum detail. The Medium preset at 1080p reaches 106.2 FPS, which is ideal for high-refresh-rate monitors. For 4K users, the Medium preset is the only setting that hits the 60 FPS mark, at 60.5 FPS. The High and Ultra presets at 4K fall below 46 FPS, which may result in noticeable stutter in a flight simulator where smooth panning is essential.

The Low preset is not recommended for this combo, as it sacrifices too much visual detail for marginal performance gains. At 1440p Low, the system produces 108 FPS, but the visual downgrade is severe. The data indicates that Medium or High at 1440p provides the best experience, with Medium being the safest choice for consistent frame rates.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, with a base clock of 3.70 GHz and a boost clock of 4.80 GHz. Its 64 MB of L3 cache and 8,300 million transistors position it as a high-end desktop CPU. In the context of Microsoft Flight Simulator, the CPU's role is to handle game logic, physics, and asset loading. The benchmark results show that it performs this role without becoming a bottleneck.

The CPU's single-thread performance is strong, with a Cinebench R23 single-core score of 4680 and a 3DMark single-thread score of 941. These scores suggest that the game's primary thread is well-served. The multi-thread performance is also robust, with a Cinebench R23 multi-core score of 33150 and a Passmark multithread score of 39002. However, the measured FPS data does not show a significant difference between resolutions that would indicate CPU saturation.

The CPU's percentile rank of 90, compared to the GPU's 72, further confirms that the processor is the stronger component. In this game, the CPU's 24 threads are more than adequate for the simulation's workload, and the frame rate drops at higher resolutions are attributable to the GPU's limitations. The Ryzen 9 5900X, with its 105 W TDP and PCIe Gen 4 support, provides a stable platform for the RTX 3070, but the GPU remains the deciding factor for the overall experience in Microsoft Flight Simulator.
