Microsoft Flight Simulator

Microsoft Flight Simulator presents one of the most demanding workloads in PC gaming, and the pairing of the AMD Ryzen 9 7900X with the NVIDIA GeForce RTX 4080 SUPER offers a revealing look at how this simulator scales. The data measured for this combination shows a system that is consistently capable of high frame rates, yet the pattern of performance across resolutions and settings tells a nuanced story about where the bottlenecks lie. The Ryzen 9 7900X, with its 12 cores and 24 threads, and the RTX 4080 SUPER, with its 16 GB of GDDR6X memory, are both high-end parts, but their interaction in this specific title reveals distinct behavioral characteristics. The following analysis breaks down the measured FPS data to understand what this combo delivers, how it compares to other tested configurations, and what it implies for the player experience.

Resolution Scaling

The FPS drop from 1080p to 4K is steep, but the shape of that curve is more informative than the raw numbers. At 1080p with Low settings, the system produces an average of 211.5 FPS, which is exceptionally high. Moving to 1440p Low drops that to 166.8 FPS, a reduction of roughly 21%. At 4K Low, the average falls to 123.2 FPS, which is another 26% lower than 1440p. This pattern indicates that at lower resolutions, the CPU is capable of feeding the GPU at very high rates, but the GPU is still the primary limiter as resolution increases.

The situation becomes clearer when looking at the Ultra preset. At 1080p Ultra, the average is 116.2 FPS. At 1440p Ultra, it drops to 93.3 FPS, and at 4K Ultra, it falls to 66.1 FPS. The percentage drop from 1080p to 4K at Ultra is about 43%, which is a significant but not catastrophic decline. This suggests that the RTX 4080 SUPER has enough headroom to handle the increased pixel count, but the workload scales heavily with resolution. The data implies that at 4K Ultra, the system is likely GPU-bound, as the frame rate drops below the 72.5 FPS seen at 4K High, indicating that the highest preset demands more from the graphics card than the High preset.

What is most telling is the gap between Low and Ultra at the same resolution. At 1080p, the difference is 95.3 FPS (211.5 vs 116.2), which is a massive swing. At 4K, the difference narrows to 57.1 FPS (123.2 vs 66.1). This compression of the FPS range at higher resolutions confirms that the GPU becomes the dominant constraint as resolution rises. The CPU, with its high boost clock of 5.60 GHz, appears to be less of a factor at 4K, allowing the GPU's raw power to dictate performance. The data suggests that for players targeting 4K, the Ultra preset will push the system to its limits, while the High preset offers a more comfortable margin.

CPU Role

The AMD Ryzen 9 7900X is a Zen 4 architecture processor with 12 cores and 24 threads, running at a base clock of 4.70 GHz and a boost clock of 5.60 GHz. In this game, its role is evident in the high frame rates achieved at lower resolutions. At 1080p Low, the 211.5 FPS average suggests that the CPU is capable of feeding the GPU with enough draw calls to saturate its performance. The processor's 64 MB of shared L3 cache likely helps with the streaming of terrain and scenery data, which is a known stressor for flight simulators.

The benchmark data for the CPU shows a strong single-thread performance, with a Cinebench R23 single-core score of 6168. This is critical because Microsoft Flight Simulator often relies on a few main threads for simulation logic. The multi-threaded score of 43695 in Cinebench R23 indicates that the 12 cores are also useful for background tasks and asset loading. When comparing to its nearest rivals, the Ryzen 9 7900X sits at a 93rd percentile among all CPUs, with an average benchmark score of 50556. Its closest competitor, the Intel Core Ultra 5 235, scores 50598, a delta of -0.1%, meaning the Ryzen is essentially on par. The AMD Ryzen 9 5900XT scores 50738, which is 0.4% higher, and the Intel Core i9-13980HX scores 50944, 0.8% higher. These are small margins, suggesting that the CPU is not a differentiator in this specific game when paired with a high-end GPU.

The data implies that the Ryzen 9 7900X provides a solid foundation for the RTX 4080 SUPER, but it is not the star of the show. At 4K Ultra, the CPU's influence wanes, as the GPU's rendering load becomes the limiting factor. The high frame rates at 1080p, however, demonstrate that the CPU has ample headroom to avoid bottlenecking the GPU in less demanding scenarios. The architecture's efficiency at 5 nm process node, with a TDP of 170 W, allows it to sustain these workloads without thermal throttling, which is inferred from the consistent performance across settings.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the primary driver of visual fidelity in this combo, and its specifications are substantial. It features 16 GB of GDDR6X memory on a 256-bit bus, providing a bandwidth of 736.3 GB/s. The GPU has a boost clock of 2550 MHz and a base clock of 2295 MHz, with 10240 shading units. For a game like Microsoft Flight Simulator, which is known for its detailed textures and complex lighting, the 16 GB VRAM buffer is a critical asset. The data shows that at 4K Ultra, the average FPS is 66.1, which is playable but not silky smooth. At 4K High, the average rises to 72.5 FPS, indicating that the GPU has some headroom to spare when the preset is lowered.

The GPU's benchmark performance places it at an 88th percentile among all GPUs, with an average score of 53610. Its nearest rival, the AMD Radeon RX 6900 XT, scores 53489, which is a delta of 0.2% — a negligible difference. The AMD Radeon Pro W6600M scores 53414, 0.4% higher, and the AMD Radeon RX 7700S scores 52505, which is 2.1% lower. Interestingly, the NVIDIA GeForce RTX 5070 Ti scores 52086, which is 2.9% lower than the 4080 SUPER, suggesting that this older card still holds a performance edge in general benchmarks.

In this game, the GPU's role becomes more pronounced as resolution increases. The measured FPS at 1080p Ultra (116.2) versus 4K Ultra (66.1) shows a 43% drop, which is a significant scaling cost. This suggests that the RTX 4080 SUPER is being fully utilized at 4K, and the frame rate is a direct reflection of its rendering capabilities. The memory bandwidth of 736.3 GB/s is likely a key factor in maintaining playable frame rates at 4K, where texture data is large. The data indicates that for players who prioritize maximum visual quality at 4K, the Ultra preset will demand a tolerance for frame rates in the mid-60s, while the High preset offers a smoother experience with a small visual compromise.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend heavily on the target resolution and the player's preference for smoothness over visual fidelity. At 1080p, all presets deliver high frame rates, with Low at 211.5 FPS, Medium at 164.8 FPS, and High at 125 FPS. The Ultra preset at 116.2 FPS is still very playable, and for a simulation game, the visual improvements from Ultra may be worth the slight FPS reduction. The data suggests that at 1080p, the system has enough headroom to use the Ultra preset without sacrificing responsiveness.

At 1440p, the picture is similar but with a tighter margin. The Medium preset delivers 127.9 FPS, which is a strong balance between quality and speed. High at 100.7 FPS is also smooth, while Ultra at 93.3 FPS remains above the 60 FPS threshold, making it a viable choice for players with high-refresh-rate monitors. The Low preset at 166.8 FPS is excessively high, indicating that it is not necessary to drop to the lowest settings for competitive play, as this is not a competitive title.

For 4K, the recommendations are more nuanced. The Ultra preset at 66.1 FPS is the most visually impressive, but it is close to the 60 FPS line. The High preset at 72.5 FPS offers a better safety margin and is likely the sweet spot for a consistent experience. The Medium preset at 95.8 FPS is a strong alternative if the player prioritizes frame rate over maximum details, as it provides a substantial boost over High. The Low preset at 123.2 FPS is not recommended for 4K, as it likely sacrifices too much visual quality for a frame rate that the GPU can achieve at higher settings. The data implies that for 4K, the High preset provides the best balance, delivering a smooth 72.5 FPS average without pushing the system to its limits.
