Microsoft Flight Simulator

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 5090 combination delivers exceptional performance in Microsoft Flight Simulator, with measured data showing every preset at every tested resolution clearing the 60 FPS playability threshold. This pairing ranks 55th out of 3,714 tested combos, placing it in the top 1.5% of all configurations. The benchmark results reveal a system that handles the simulator's demanding flight physics and detailed scenery rendering with substantial headroom, though the scaling patterns between resolutions and presets tell a nuanced story about where the bottleneck shifts.

Measured FPS Breakdown

At 1920x1080, the combo produces framerates that exceed the needs of virtually any display. Low settings deliver an average of 239.5 FPS, which drops to 185.9 FPS at Medium, 141.9 FPS at High, and 133.4 FPS at Ultra. The gap between Low and Ultra is substantial—a 106.1 FPS difference—but even the most demanding preset at this resolution never approaches the 60 FPS threshold. The step from Low to Medium costs 53.6 FPS, while the step from Medium to High costs 44 FPS, and the step from High to Ultra costs only 8.5 FPS. This compression at the top end suggests that Ultra settings are extracting near-maximum performance from the hardware without excessive penalty.

Moving to 2560x1440, the framerates remain high but show the expected reduction from the 1080p results. Low settings average 192.9 FPS, Medium drops to 148.1 FPS, High comes in at 112.3 FPS, and Ultra produces 108.3 FPS. The relative ordering stays consistent, but the differences between presets narrow slightly. The Low-to-Medium gap is 44.8 FPS, Medium-to-High is 35.8 FPS, and High-to-Ultra is just 4 FPS. At this resolution, the Ultra preset is barely more demanding than High, which indicates the GPU has ample resources to handle the extra visual fidelity without a major performance hit.

At 3840x2160, the 4K results show the most significant scaling pressure. Low settings average 141.6 FPS, Medium drops to 106.8 FPS, High comes in at 81 FPS, and Ultra produces 75.7 FPS. The differences between presets are more pronounced here: Low-to-Medium costs 34.8 FPS, Medium-to-High costs 25.8 FPS, and High-to-Ultra costs 5.3 FPS. Even at the most demanding configuration tested, the combo maintains an average above 75 FPS, which is comfortably above the playability threshold. The 4K Ultra result of 75.7 FPS represents the lowest average across all tested scenarios, yet it still leaves significant headroom before hitting 60 FPS.

Comparing across resolutions, the scaling follows a predictable pattern. The 1080p to 1440p transition costs roughly 20-25% of the framerate depending on the preset, while the 1440p to 4K transition costs another 25-30%. The Ultra preset shows the smallest absolute drops between resolutions, suggesting that at higher settings the workload shifts toward the GPU in a way that the RTX 5090 handles efficiently. Low settings show the largest absolute drops, which hints at CPU involvement in the lower-detail rendering path.

CPU and GPU Roles

The data reveals a shift in bottleneck behavior as resolution increases. At 1920x1080, the massive framerates—239.5 FPS on Low—indicate that the CPU is playing a more significant role in limiting performance, since the GPU has relatively few pixels to render. The Ryzen 9 9900X, with its 12 cores and 24 threads, provides strong single-threaded performance, which is critical for flight simulation workloads that often rely on a few heavily loaded threads. The 1080p Low result being nearly 100 FPS higher than the 4K Low result suggests that at lower resolutions, the rendering pipeline is not the primary constraint.

As resolution climbs to 2560x1440, the GPU begins to take on more responsibility, but the CPU still has influence. The 1440p Ultra result of 108.3 FPS versus the 1080p Ultra result of 133.4 FPS shows a 25.1 FPS drop from pixel count alone. This indicates a balanced workload where neither component is fully saturated. The RTX 5090's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth provide ample resources for the simulator's texture streaming and geometry processing at this resolution.

At 3840x2160, the GPU becomes the dominant factor. The 4K Ultra result of 75.7 FPS versus the 1440p Ultra result of 108.3 FPS represents a 32.6 FPS drop, which is the largest absolute penalty from a resolution increase for any preset. This pattern confirms that at 4K, the RTX 5090's rendering throughput is the limiting factor, while the CPU has enough headroom to feed the GPU consistently. The fact that even 4K Ultra stays above 75 FPS suggests the CPU is not causing any major stalls or frame pacing issues.

The scaling between presets at each resolution further clarifies the component roles. At 1080p, the difference between Low and Ultra is 106.1 FPS, which is the largest preset spread across all resolutions. This wide spread indicates that the CPU can handle the increased draw calls and simulation logic at higher settings without bottlenecking, allowing the GPU's workload to scale with visual fidelity. At 4K, the Low-to-Ultra spread narrows to 65.9 FPS, showing that the GPU is becoming the primary constraint as pixel count rises, and the additional settings have less relative impact.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which achieves an average of 133.4 FPS. This is the highest quality setting tested, and the combo clears the threshold by more than double. There is no reason to compromise on visual fidelity at this resolution, as even the most intensive configuration leaves substantial performance headroom.

At 2560x1440, the best settings are also Ultra, with an average of 108.3 FPS. The 1440p Ultra preset delivers smooth performance that exceeds the 60 FPS threshold by 48.3 FPS, making it a safe choice for high-refresh-rate displays. The gap between High and Ultra at this resolution is only 4 FPS, so choosing Ultra does not carry a meaningful performance penalty relative to the visual benefits it provides.

At 3840x2160, the best settings remain Ultra, with an average of 75.7 FPS. This is the only resolution where the combo approaches the threshold more closely, but 75.7 FPS still provides a comfortable 15.7 FPS margin above 60 FPS. The data shows that all four presets at 4K—Low at 141.6 FPS, Medium at 106.8 FPS, High at 81 FPS, and Ultra at 75.7 FPS—clear the playability threshold, so users with 4K displays can select any quality level without dropping below 60 FPS.
