Microsoft Flight Simulator

The AMD Ryzen 9 5900X and NVIDIA GeForce RTX 3060 Ti pairing delivers a playable, if not always flawless, experience in Microsoft Flight Simulator. The data reveals a system that scales predictably with resolution and settings, where the GPU becomes the primary bottleneck at higher loads, but the capable 12-core processor ensures the sim never feels CPU-starved.

Resolution Scaling

The measured FPS data shows a clear and consistent performance drop as resolution increases from 1920x1080 to 3840x2160. At the Low preset, the average frame rate falls from 124 FPS at 1080p to 100 FPS at 1440p, and finally to 74 FPS at 4K. This represents a 21% reduction from 1080p to 1440p and a further 26% reduction from 1440p to 4K, resulting in a total 40% performance loss from the lowest to the highest resolution tested.

The pattern intensifies with higher graphical presets. At High settings, the system delivers 73 FPS at 1080p, drops to 58 FPS at 1440p, and reaches 43 FPS at 4K. The scaling from 1440p to 4K at High settings shows a 26% performance hit, which is steeper than the 20% drop seen between 1080p and 1440p. This suggests that at 4K, the GPU is working significantly harder, and the frame rate is becoming more dependent on the graphics card's capabilities.

The Ultra preset, which is the most demanding setting tested, shows the most severe scaling. Average FPS starts at 69 at 1080p, falls to 56 at 1440p, and bottoms out at 41 at 4K. The difference between 1080p and 4K at Ultra is 28 FPS, a 41% reduction. This is the largest absolute drop across all settings, confirming that the RTX 3060 Ti is the limiting component at higher resolutions when the graphical load is maximized.

Interestingly, the Medium preset provides the only rows with min and max FPS data. At 4K Medium, the average is 57 FPS with a min of 49 and a max of 66. At 1440p Medium, the average rises to 78 FPS with a range of 66 to 89. At 1080p Medium, the average is 96 FPS, with a minimum of 82 and a maximum of 111. The relatively tight spread between min and max FPS at each resolution suggests that the frame pacing is fairly stable, with no major stutters or hitches that would indicate a CPU bottleneck.

The scaling data indicates that the RTX 3060 Ti is the primary limiting factor at 4K and at high/ultra settings. The CPU, with its 12 cores and 24 threads, has enough headroom to feed the GPU at lower resolutions, but as the pixel count and graphical complexity rise, the GPU's workload becomes the deciding factor in frame rate. The transition from 1440p to 4K is particularly punishing, with an average performance drop of over 25% across all presets, which is a strong indicator of GPU-bound performance.

GPU Role

The NVIDIA GeForce RTX 3060 Ti, built on the Ampere architecture, is the primary driver of the resolution scaling observed in the data. With 8 GB of GDDR6 memory on a 256-bit bus providing 448.0 GB/s of bandwidth, the card has a solid foundation for handling Microsoft Flight Simulator's detailed textures and complex geometry. The GPU's base clock is 1410 MHz with a boost clock of 1665 MHz, and its 4864 shading units are tasked with rendering the game's vast landscapes and intricate aircraft models.

The RTX 3060 Ti's 80 ROPs are responsible for the final pixel output, and this number directly impacts performance at higher resolutions. At 4K, the pixel count is over four times that of 1080p, and the ROPs must work significantly harder to fill the frame buffer. This is reflected in the measured FPS: at 4K Ultra, the card manages only 41 FPS, a drop of 28 FPS from the 1080p Ultra score of 69 FPS. The GPU's fill rate, listed as 133.2 GPixel/s, is a limiting factor at these extreme resolutions.

The card's memory capacity of 8 GB is also a consideration. While the data does not show a direct memory usage measurement, the significant performance drops at 4K suggest that the card is working near its limits. The 448.0 GB/s of bandwidth helps, but the capacity may be a constraint for the highest texture quality settings at 4K. The fact that the Ultra preset at 4K yields a 41 FPS average, below the 60 FPS target for smooth gameplay, indicates that the GPU is the bottleneck in this scenario.

In contrast, the GPU's performance at 1080p is much stronger. At Low settings, it achieves 124 FPS, and even at Ultra, it maintains 69 FPS. This shows that the RTX 3060 Ti has ample compute power for lower resolutions, and the CPU (the Ryzen 9 5900X) is not holding the system back. The 16.20 TFLOPS of FP32 performance is sufficient for 1080p gaming, and the card only begins to struggle when the resolution is increased to 4K.

The GPU's nearest rivals, according to the data, are the AMD Radeon RX 9060 (0.7% faster), the AMD Radeon Pro 5600M (1.4% slower), and the AMD Radeon RX 5700 XT (1.4% slower). These are all within a tight 2% performance band, indicating that the RTX 3060 Ti is a mid-range card that offers consistent performance relative to its peers. In Microsoft Flight Simulator, this translates to a card that can handle 1080p and 1440p with ease but requires settings reductions at 4K to maintain playable frame rates.

Settings Recommendations

The measured FPS data provides a clear picture of which settings offer the best balance between visual quality and performance. For players prioritizing a smooth frame rate, the Medium preset is the standout choice. At 1920x1080, it delivers an average of 96 FPS, which is well above the 60 FPS target and provides a comfortable margin for dips in complex scenes. The minimum FPS of 82 at this setting ensures that even the most demanding moments in the sim, such as flying over dense cities, will remain fluid.

At 2560x1440, the Medium preset offers an average of 78 FPS, with a minimum of 66 FPS. This is still a very playable experience and represents a good compromise for users with 1440p monitors. The step up to High settings at this resolution yields 58 FPS, which is below the 60 FPS threshold and may result in occasional perceived stutter. Therefore, for a 1440p experience, Medium is the recommended setting.

For 4K displays, the choice becomes more constrained. The Medium preset at 3840x2160 averages 57 FPS, which is borderline playable but may dip in busy areas. The High preset at 4K drops to 43 FPS, which is less ideal for a fluid experience. Given the data, the Medium preset is the only viable option for 4K, offering a playable frame rate without sacrificing too much visual fidelity. The Low preset at 4K does achieve 74 FPS, but the visual quality reduction is likely too severe for most users.

The High preset is a reasonable choice for 1080p gaming, delivering an average of 73 FPS. This is a significant improvement over Medium in terms of visual detail, and the frame rate is still high enough for a smooth experience. However, the Ultra preset at 1080p, which averages 69 FPS, offers diminishing returns in performance for the extra visual settings. The 4 FPS difference between High and Ultra at 1080p is minimal, so users may choose either based on their preference for maximum visual quality.

In summary, the data suggests that Medium is the "sweet spot" preset for this combination across all resolutions. It provides a playable frame rate at 4K and a highly fluid experience at 1080p and 1440p. For users with high-refresh-rate 1080p monitors, the High preset is a strong alternative that offers more visual detail while maintaining a frame rate above 70 FPS.
