Microsoft Flight Simulator

The AMD Ryzen 9 9900X3D and NVIDIA GeForce RTX 5070 combination delivers a consistently playable experience in Microsoft Flight Simulator, with performance scaling that clearly shows the GPU as the primary bottleneck at higher resolutions. The data indicates a system that excels at 1080p, remains fluid at 1440p, and still manages respectable frame rates at 4K, making it a versatile pairing for this demanding flight sim.

Resolution Scaling

The measured FPS data reveals a classic resolution scaling curve that highlights the balance between the 12-core Ryzen 9 9900X3D and the RTX 5070. Moving from 1920x1080 to 2560x1440 to 3840x2160 shows a steady, predictable decline in average frame rates across all settings presets, with the gap between resolutions widening as the GPU workload increases.

At 1080p with High settings, the combo produces 103 FPS. Stepping up to 1440p drops that to 83 FPS, a 19% reduction, while 4K further reduces it to 61 FPS, a 41% decline from the 1080p baseline. This pattern suggests that at 1080p, the CPU is still feeding the GPU adequately, but the rendering load is already substantial. The Low preset tells a more dramatic story: 176 FPS at 1080p, 142 FPS at 1440p, and 105 FPS at 4K. The 4K figure here is notably close to the 1080p High result, indicating that even with minimal graphical load, the 4K pixel count is a significant hurdle for the RTX 5070’s 12 GB of GDDR7 memory and 192-bit bus.

The Medium preset provides the only complete dataset with min and max FPS values. At 1080p, it averages 137 FPS with a minimum of 116 and maximum of 157. At 1440p, the average falls to 110 FPS with min/max of 94/127. At 4K, the average drops to 81 FPS with min/max of 69/94. The consistency of the minimum frame rates—staying above 60 FPS even at 4K—suggests that the CPU rarely becomes a limiting factor, even in complex flight scenarios. The Ultra preset shows the steepest scaling: 98 FPS at 1080p, 79 FPS at 1440p, and 58 FPS at 4K. This 4K Ultra result is the only measured configuration that falls below the 60 FPS threshold, indicating that this combo’s ceiling is just short of max settings at 4K.

The data strongly implies that the RTX 5070 is the limiting component as resolution increases. The CPU’s 128 MB of L3 cache and 24 threads are more than sufficient to keep up with the GPU’s output, evidenced by the relatively small FPS drops between 1080p and 1440p compared to the larger drops between 1440p and 4K. For users targeting 4K, the Low preset at 105 FPS or Medium at 81 FPS are the realistic options, while 1440p Ultra at 79 FPS offers a strong balance of fidelity and smoothness.

Measured FPS Breakdown

The dataset includes 12 distinct measurement points across three resolutions and four settings presets. Here is the full breakdown:

1920x1080 (Full HD):

• Low: 176 FPS average
• Medium: 137 FPS average, 116 FPS minimum, 157 FPS maximum
• High: 103 FPS average
• Ultra: 98 FPS average

2560x1440 (Quad HD):

• Low: 142 FPS average
• Medium: 110 FPS average, 94 FPS minimum, 127 FPS maximum
• High: 83 FPS average
• Ultra: 79 FPS average

3840x2160 (4K UHD):

• Low: 105 FPS average
• Medium: 81 FPS average, 69 FPS minimum, 94 FPS maximum
• High: 61 FPS average
• Ultra: 58 FPS average

At 1080p, every preset exceeds 90 FPS, with Low nearly doubling the 60 FPS threshold at 176 FPS. The gap between High and Ultra at 1080p is only 5 FPS (103 vs. 98), suggesting that the Ultra preset’s additional visual effects are relatively cheap at this resolution. The Medium preset’s minimum of 116 FPS indicates that even in the most demanding scenes, the system never drops below a very smooth frame rate.

At 1440p, the Ultra preset still maintains 79 FPS average, which is playable for most users. The drop from 1080p Ultra (98 FPS) to 1440p Ultra (79 FPS) represents a 19% reduction, while the drop from 1440p Ultra to 4K Ultra (58 FPS) is 27%. This accelerating decline underscores the GPU’s memory bandwidth limitations at higher pixel counts.

At 4K, the Medium preset’s minimum FPS of 69 is the key data point—it proves that even in complex flight scenarios, the system stays comfortably above 60 FPS. The High preset at 61 FPS average is borderline, and Ultra at 58 FPS dips below the ideal threshold. The Low preset at 105 FPS shows that the RTX 5070 has raw rasterization power, but the 12 GB VRAM and 192-bit bus limit how much detail can be pushed at 4K before performance degrades.

GPU Role

The NVIDIA GeForce RTX 5070 is the decisive factor in this combo’s 4K performance. With 12 GB of GDDR7 memory on a 192-bit bus, the GPU delivers 672.0 GB/s of bandwidth. This is sufficient for 1080p and 1440p at all settings, but the 4K Ultra result of 58 FPS suggests that memory capacity or bandwidth becomes a constraint at the highest pixel counts and detail levels.

The GPU’s boost clock of 2512 MHz and 6144 shading units provide substantial compute throughput, evidenced by the 30.87 TFLOPS FP32 performance. This raw power translates into strong 1080p results, where the Low preset reaches 176 FPS. However, the 4K scaling shows that the GPU’s 80 ROPs and 192 TMUs struggle to fill the 8.3 million pixels of a 4K frame at Ultra settings, resulting in the only sub-60 FPS measurement in the entire dataset.

The GPU’s 48 RT cores and 192 tensor cores are present but not directly measured in this flight sim data. The game’s reliance on traditional rasterization is evident in the performance scaling, which follows a predictable path based on resolution and pixel count. The GPU’s 82nd percentile ranking against all GPUs and its average benchmark score of 40377 indicate that it is a solid mid-to-high-end part, but not a flagship.

The RTX 5070’s nearest rivals in the benchmark database—the AMD Radeon Pro 580 and Radeon Pro WX 7100—are professional workstation cards, not gaming GPUs. This comparison highlights that the RTX 5070’s gaming performance is distinct from its compute-oriented competitors. The 2% delta against the NVIDIA RTX A500 Mobile shows that the desktop card maintains a lead over mobile variants, as expected. In the context of this flight sim, the GPU’s 12 GB VRAM is adequate for the current settings, but the 4K Ultra result suggests that users who want headroom for future expansions or higher detail settings may need to reduce resolution or accept the 58 FPS average.

Settings Recommendations

Based on the measured data, the optimal settings depend heavily on the target resolution and whether the user prioritizes frame rate consistency or visual fidelity.

For 1080p users: The High preset at 103 FPS is the sweet spot. It provides a significant visual upgrade over Medium (137 FPS) while maintaining a frame rate well above the 60 FPS threshold. The Ultra preset at 98 FPS offers only a 5 FPS penalty for maximum visual quality, making it a viable choice for those with 144 Hz or higher refresh rate monitors who can tolerate the slight dip. The Medium preset’s minimum of 116 FPS is the most consistent, but the visual difference between Medium and High is typically noticeable in a flight sim’s cockpit and terrain detail.

For 1440p users: The High preset at 83 FPS is the recommended baseline. It offers a smooth experience with good detail. The Ultra preset at 79 FPS is nearly identical in performance and provides the best visual quality—the 4 FPS difference is negligible, so users with capable monitors should choose Ultra. The Medium preset at 110 FPS is ideal for competitive or high-refresh-rate play, but the min FPS of 94 still suggests occasional dips. Given the small gap between High and Ultra, the Ultra preset is the best overall choice for 1440p.

For 4K users: The Medium preset at 81 FPS is the clear recommendation. It delivers the best combination of visual quality and frame rate, with a minimum of 69 FPS ensuring smoothness even in busy airport environments. The High preset at 61 FPS is playable but leaves little headroom for complex scenes, and the Ultra preset at 58 FPS falls below the 60 FPS threshold, which can result in noticeable stutter. The Low preset at 105 FPS is only recommended for users who prioritize frame rate over all visual aspects, as the graphical fidelity loss is substantial.

The data shows that this combo is best utilized at 1440p with Ultra settings, where it achieves 79 FPS and delivers the full visual experience of Microsoft Flight Simulator without compromising smoothness. At 4K, the Medium preset is the practical ceiling, offering a playable 81 FPS average with acceptable minimums. The single sub-60 FPS measurement at 4K Ultra (58 FPS) serves as a clear boundary for this hardware pairing, indicating that users should not expect max settings at 4K without additional GPU headroom.
