Microsoft Flight Simulator

Microsoft Flight Simulator is a demanding title that scales heavily with both CPU and GPU resources, and the measured data for the AMD Ryzen 5 7600X paired with the NVIDIA GeForce RTX 5090 shows a configuration capable of delivering high frame rates across all tested presets. The benchmark results indicate that the choice of graphics preset has a more significant impact on performance at 4K resolution than at 1080p, which is typical for a simulation where the CPU often becomes a bottleneck at lower resolutions. This analysis will break down the optimal settings, the role of the GPU's specifications, the combo's standing among tested systems, and how performance scales with resolution.

Settings Recommendations

The benchmark data provides clear guidance on which preset offers the best balance of visual fidelity and performance for this specific hardware combination. At 4K resolution, the "High" preset delivers an average of 84.9 FPS, which is a smooth and playable experience for a flight simulator. Moving up to "Ultra" drops the average to 79.6 FPS, a relatively small penalty of about 5 FPS for the highest visual quality, but the "Medium" preset at 109 FPS and "Low" at 142.5 FPS show that there is substantial headroom for higher refresh rates if visual detail is sacrificed.

At 1440p, the "Ultra" preset achieves an average of 109.6 FPS, which is nearly identical to the 4K "Medium" setting, demonstrating how resolution scaling affects the load on the GPU. The "High" preset at this resolution produces 113 FPS, making it the most sensible choice for users with a 144Hz monitor who want a mix of quality and speed. The "Low" preset at 1440p hits 194.9 FPS, which is excellent for competitive or high-refresh displays, but the visual compromise is significant for a game that is about scenery.

At 1080p, the data shows that the CPU is the primary limiting factor. The "Ultra" preset yields 132.6 FPS, while "High" reaches 140.5 FPS, "Medium" hits 187.6 FPS, and "Low" peaks at 215.9 FPS. The differences between presets are much smaller than at higher resolutions, suggesting that the Ryzen 5 7600X is struggling to feed the RTX 5090 with enough frames. For the best experience at this resolution, "High" is the recommended preset, as it provides a substantial visual upgrade over "Medium" while still maintaining a frame rate above 140 FPS, which is well within the range of most high-refresh monitors.

Overall, the "High" preset is the recommended choice for this combo, as it provides a strong balance at all three tested resolutions. At 4K, it offers a playable 84.9 FPS, at 1440p it reaches 113 FPS, and at 1080p it hits 140.5 FPS, making it a versatile option that does not require constant tweaking.

GPU Role

The NVIDIA GeForce RTX 5090 is a flagship graphics card with specifications that are designed to handle extreme workloads. The data shows it has a boost clock of 2407 MHz, a memory clock of 1750 MHz with 28 Gbps effective speed, and a massive 32 GB of GDDR7 memory on a 512-bit bus. This memory configuration provides a bandwidth of 1.79 TB/s, which is crucial for a game like Microsoft Flight Simulator that streams large amounts of terrain and texture data. The 32 GB frame buffer is particularly relevant for 4K Ultra settings, where the game can consume a large amount of VRAM, and the data indicates that the card has no trouble maintaining high frame rates at that resolution.

The GPU's 104.8 TFLOPS of FP32 performance and 1,636.8 GTexel/s texture rate are among the highest on the market, allowing it to render complex scenes with dense geometry and high-resolution textures. In this test, the RTX 5090 is clearly not the bottleneck at 1080p, as the frame rates at "Low" settings (215.9 FPS) are far higher than at "Ultra" (132.6 FPS), with the gap narrowing as resolution increases. At 4K, the GPU is more heavily utilized, and the difference between "Low" (142.5 FPS) and "Ultra" (79.6 FPS) is much larger, indicating that the graphics card is now the primary driver of performance.

The data suggests that the RTX 5090's massive memory bandwidth and compute power are well-suited for this title, but its potential is only fully realized at higher resolutions. At 1080p, the CPU's limits prevent the GPU from reaching its maximum output, as evidenced by the relatively small performance gains from lowering settings. The GPU's 575 W TDP and 950 W suggested PSU are high, but the performance it delivers in this simulation justifies the power requirements for users seeking the best possible visuals.

How This Combo Ranks

The AMD Ryzen 5 7600X and NVIDIA GeForce RTX 5090 combination ranks 9th out of 1795 tested combos in this game, placing it in the top 1% of all systems tested by the database. The data shows that this is an exceptionally strong pairing, with the CPU's 83rd percentile ranking among all CPUs and the GPU's 94th percentile ranking among all GPUs contributing to the overall high performance. The combo's rank of 9 confirms the fact that the RTX 5090 is a top-tier part, even when paired with a mid-range CPU like the 7600X.

Looking at the nearest rivals for the CPU, the Ryzen 5 7600X has an average benchmark score of 26272, which is nearly identical to the AMD Ryzen 7 PRO 6850U (26262) and the AMD Ryzen 7 7735U (26305). The deltaPct values are within 0.2% of these rivals, indicating that the CPU's performance is on par with these other parts. However, the GPU's nearest rivals show a more interesting picture; the RTX 5090 has an average score of 84306, which is 0.1% higher than the RTX 5090 D (84241) and 1.3% higher than the AMD Radeon PRO W6600 (83209).

The high combo rank suggests that the RTX 5090 is the dominant component in this pairing, as the CPU's performance is only average compared to other tested processors. The data shows that the combo's rank is driven by the GPU's exceptional capabilities, and the system is likely to be limited by the CPU in CPU-bound scenarios. For a flight simulator, which is known for being CPU-intensive, this could be a potential bottleneck, but the measured frame rates at 4K Ultra (79.6 FPS) show that the combination is still very capable of delivering a high-quality experience.

A: At 2560x1440, the frame rate drops from 194.9 FPS on "Low" to 109.6 FPS on "Ultra," suggesting that the GPU is becoming more of a limiting factor at this resolution, though the CPU still plays a role.

Resolution Scaling

The performance scaling from 1080p to 4K shows a clear shift in the limiting component. At 1080p with the "Low" preset, the system achieves 215.9 FPS, which drops to 194.9 FPS at 1440p, and then falls dramatically to 142.5 FPS at 4K. This represents a 34% decrease in performance from 1080p to 4K, indicating that the GPU is starting to become more involved. However, with the "Ultra" preset, the drop is much steeper: 132.6 FPS at 1080p, 109.6 FPS at 1440p, and 79.6 FPS at 4K, which is a 40% reduction. The widening gap between presets as resolution increases shows that the RTX 5090's workload is scaling with pixel count.

The data suggests that at 1080p, the CPU is the primary limiting factor, as the frame rates are high but do not scale proportionally with the GPU's power. The difference between the "Low" and "Ultra" presets at 1080p is 83.3 FPS, while at 4K, the same difference is 62.9 FPS. This indicates that the GPU is being utilized more effectively at higher resolutions, where it can stretch its legs. The "Medium" preset follows a similar trend, with 187.6 FPS at 1080p, 148.5 FPS at 1440p, and 109 FPS at 4K, showing a consistent 42% drop from 1080p to 4K.

For users targeting high refresh rates, the 1080p "Low" setting provides the highest frame rates, but the experience is compromised visually. A more balanced approach would be to use the "High" preset at 1440p, which delivers 113 FPS, a figure that is only slightly lower than the 140.5 FPS at 1080p but with significantly better image quality. The 4K resolution is best suited for the "High" or "Medium" presets, as the Ultra setting drops below 80 FPS, which may be acceptable for a flight sim but not ideal for all users. In summary, the data shows that this combo is well-balanced for 1440p gaming, offering high frame rates with good visual fidelity, while 4K requires a compromise between settings and performance.
