Microsoft Flight Simulator

Microsoft Flight Simulator with the AMD Ryzen 5 7600X and NVIDIA GeForce RTX 4090 produces a benchmark profile that is heavily defined by the simulation's engine limits and the substantial gap between the CPU's processing headroom and the GPU's raw throughput. The data indicates a system that scales predictably with resolution, yet reveals a distinct plateau at lower resolutions where the CPU becomes the primary constraint. This combination ranks 28th out of 1795 tested combos in this specific title, placing it in the top 1.6% of all tested pairings, a position that reflects the strength of both components but also highlights the specific bottlenecks this demanding simulator presents.

Resolution Scaling

The measured FPS data shows a clear and expected inverse relationship between resolution and frame rate, but the magnitude of the drops reveals crucial insights into the system's balance. At 1080p with Low settings, the combo achieves 218 FPS, which drops to 186.8 FPS at 1440p and further to 135.3 FPS at 4K. This represents a 14.3% drop from 1080p to 1440p and a 38% drop from 1080p to 4K. The relatively modest decline when moving to 1440p suggests that the CPU is still able to feed frames adequately, but the larger drop to 4K indicates the GPU is beginning to take on a more significant workload.

However, the scaling pattern changes dramatically when looking at higher settings. With Ultra settings, the frame rate only declines from 130.6 FPS at 1080p to 104 FPS at 1440p (a 20.4% drop) and then to 77.2 FPS at 4K (a 40.9% drop from 1080p). This steeper decline at Ultra settings compared to Low settings is a classic indicator of a GPU-bound scenario. The data suggests that at Low settings, the CPU is the limiting factor even at 4K, as the frame rate remains remarkably high (135.3 FPS), whereas at Ultra settings, the increased graphical load on the RTX 4090 becomes the dominant constraint, particularly as pixel count rises.

The difference in scaling between settings is more revealing than the absolute numbers. Moving from Low to Ultra at the same resolution incurs a significant performance cost: a 40.1% reduction in FPS at 1080p (218 to 130.6 FPS) and a 42.9% reduction at 4K (135.3 to 77.2 FPS). This consistency suggests that while the GPU's workload scales with settings, the CPU's ability to prepare frames is not the primary bottleneck at these higher graphical presets. The simulator's engine appears to place a heavy single-threaded burden, which the Ryzen 5 7600X handles capably, but the RTX 4090's performance is still being heavily taxed by the visual complexity at higher settings.

How This Combo Ranks

The combination achieves a rank of 28 out of 1795 tested combos in Microsoft Flight Simulator, which is a top-tier result. This ranking places it ahead of 98.4% of all other tested CPU and GPU pairings, a position that underscores the synergistic strength of the Ryzen 5 7600X and RTX 4090 for this specific title. The CPU's percentile rank against all CPUs is 83, indicating it performs better than the vast majority of processors in general benchmarks, while the GPU's percentile rank is 91, showing it is also a high performer relative to other graphics cards.

This high ranking is not merely a function of the GPU's power; it also reflects the CPU's ability to keep up with the demands of a flight simulator, which is known for its complex physics and scenery calculations. The Ryzen 5 7600X, with its 6 cores and 12 threads, demonstrates sufficient processing power to avoid being a significant bottleneck, allowing the RTX 4090 to flex its capabilities. The data shows that this pairing is far more effective than average, with the nearest CPU rivals in general benchmarks, such as the AMD Ryzen 7 PRO 6850U and AMD Ryzen 7 5700X, being separated by less than 0.2% in average score, but the in-game context with the RTX 4090 provides a much clearer performance picture.

GPU Role

The NVIDIA GeForce RTX 4090 plays a dominant role in this combo, particularly at higher resolutions and settings. The card's 24 GB of GDDR6X memory on a 384-bit bus provides a 1.01 TB/s bandwidth, which is essential for handling the high-resolution textures and complex scenery in Microsoft Flight Simulator. The benchmark results show that the GPU is rarely the limiting factor at 1080p, but its role becomes more pronounced as resolution increases. At 4K Ultra, the card's output of 77.2 FPS is still highly playable, but the 43% reduction compared to 1080p Ultra highlights the significant pixel load.

The RTX 4090's clock speeds, with a base of 2235 MHz and a boost of 2520 MHz, are high for a graphics card, and the data suggests that this contributes to its ability to maintain high frame rates even under load. The GPU's performance in synthetic benchmarks, such as a Passmark G3D score of 38194, places it in the 91st percentile of all GPUs, and its nearest rivals, including the NVIDIA Tesla T4 and AMD Radeon Pro Vega 56, show that it is at the top of the performance hierarchy. In this game, the GPU's role is to handle the rendering pipeline efficiently, and the measured FPS indicates that it does so without creating a major bottleneck until the highest settings are combined with 4K resolution.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the combo delivers 218 FPS on Low, 183.6 FPS on Medium, 138.9 FPS on High, and 130.6 FPS on Ultra. These numbers show that even at the most demanding 1080p preset, the frame rate is well above the threshold for smooth gameplay. Moving to 2560x1440, the results are 186.8 FPS on Low, 144.4 FPS on Medium, 109.5 FPS on High, and 104 FPS on Ultra. The drop from 1080p to 1440p is noticeable but not severe, with the Ultra preset only seeing a 20.4% reduction.

At 3840x2160, the performance is still robust, with 135.3 FPS on Low, 103.6 FPS on Medium, 80.3 FPS on High, and 77.2 FPS on Ultra. The 4K Low setting result of 135.3 FPS is particularly interesting, as it shows the CPU can still push a high frame rate even when the GPU has to render four times the pixels of 1080p. The difference between High and Ultra at 4K is minimal (80.3 vs 77.2 FPS), suggesting a diminishing return in performance for the increased graphical fidelity. The data indicates that for a 60 FPS target, this combo can handle Ultra settings at 4K without issue, and even the most demanding scenario tested (4K Ultra) exceeds that target by a significant margin.
