Resolution Scaling

The measured frame rates for Microsoft Flight Simulator with the AMD Ryzen 7 9700X and NVIDIA GeForce RTX 5090 reveal a clear pattern of GPU-bound scaling as resolution increases. At 1080p with Low settings, the combo delivers 243.7 FPS, but this drops to 190.9 FPS at 1440p and further to 141.4 FPS at 4K. This represents a 42% reduction from 1080p Low to 4K Low, indicating that the RTX 5090's rendering workload is scaling predictably with pixel count.

The High preset tells a similar story with less headroom. At 1080p High, the system produces 141.4 FPS, which falls to 113.9 FPS at 1440p and 81.9 FPS at 4K. The gap between 1080p and 4K High is 59.5 FPS, a 42% decline that mirrors the Low preset's scaling. This consistency suggests the GPU is the primary limiter across all tested configurations, as the frame rate reduction tracks closely with the 4x pixel count difference between 1080p and 4K.

Ultra settings exhibit the steepest absolute drop. The system starts at 135.6 FPS in 1080p Ultra, drops to 105.9 FPS at 1440p, and bottoms out at 78.9 FPS in 4K Ultra. The 4K Ultra result is the lowest measured value in the entire dataset, confirming that this flight simulator's highest preset places substantial demands on the graphics pipeline even with the flagship RTX 5090.

Medium settings occupy the middle ground. From 188.2 FPS at 1080p, the frame rate declines to 153 FPS at 1440p and 108.2 FPS at 4K. The 4K Medium result is 80 FPS lower than 1080p Medium, a 42.5% reduction that once again aligns with the resolution scaling pattern. Notably, the 4K Medium score of 108.2 FPS is higher than the 1080p Ultra score of 135.6 FPS only in absolute terms; the relative scaling remains consistent.

The data indicates that the CPU is not a bottleneck at any resolution. The Ryzen 7 9700X's 8 cores and 16 threads provide sufficient processing headroom, as evidenced by the smooth frame rate progression across resolutions. Even at 1080p Low, where the GPU has the least work, the system reaches 243.7 FPS without hitting a CPU-imposed ceiling. The limiting component is clearly the GPU's rendering throughput, which scales predictably with resolution and settings.

Settings Recommendations

Examining the measured rows, the most balanced experience appears at 1440p High, where the system delivers 113.9 FPS. This result provides smooth gameplay while maintaining visual fidelity above Medium. The 1440p Medium preset offers 153 FPS, which represents the highest frame rate at that resolution with moderate quality settings, but the jump to High only costs 39.1 FPS while providing substantial visual improvements typical of flight simulator terrain and aircraft detail.

For 4K users, the High preset at 81.9 FPS is the recommended choice. It stays above the 60 FPS threshold comfortably and avoids the 78.9 FPS Ultra result, which offers diminishing returns for a 3 FPS differential. The 4K Medium at 108.2 FPS is viable for those prioritizing frame rate over visual quality, but High provides a better balance for a simulator where scenery detail directly impacts the experience.

At 1080p, the Ultra preset at 135.6 FPS is the clear recommendation. The system has ample headroom at this resolution, and the 5.8 FPS difference between Ultra and High (135.6 vs. 141.4 FPS) is negligible compared to the visual quality gains. Even the 1080p Medium preset at 188.2 FPS is unnecessary when Ultra maintains such high frame rates.

The Low presets across all resolutions—243.7 FPS at 1080p, 190.9 FPS at 1440p, and 141.4 FPS at 4K—are only relevant for competitive play or maximum refresh rate displays. Given that Microsoft Flight Simulator is not a competitive title, these settings sacrifice too much visual fidelity for frame rates that exceed display capabilities. The data suggests that High is the sweet spot for most users, with Ultra reserved for 1080p where performance remains excellent.

GPU Role

The NVIDIA GeForce RTX 5090 plays the dominant role in this combo's Microsoft Flight Simulator performance. Its 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is critical for streaming the high-resolution terrain textures and detailed aircraft models that flight simulators load continuously. The memory configuration ranks in the 94th percentile of all GPUs, with an average benchmark score of 84,306.

The GPU's clock speeds are set at a base of 2017 MHz and a boost of 2407 MHz. These clocks, combined with 21,760 shading units, 680 texture mapping units, and 176 raster operation pipelines, produce a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s. The FP32 performance of 104.8 TFLOPS indicates substantial compute headroom for the physics and weather simulations that run alongside rendering.

The RTX 5090's nearest rival, the RTX 5090 D, scores 84,241 in average benchmarks, just 0.1% behind. The RTX 5050 Mobile scores 84,171, also 0.2% behind. These small deltas suggest that the desktop RTX 5090 is performing near the top of its class, though the AMD Radeon PRO W6600 at 83,209 (1.3% behind) shows that the gap to other architectures is not enormous.

In game-specific terms, the GPU's role becomes evident in the resolution scaling data. The 4K Ultra result of 78.9 FPS represents the lowest measured frame rate, indicating that the GPU is fully utilized at this setting. The 1080p Low result of 243.7 FPS shows the GPU's headroom when pixel count is low, but the consistent scaling pattern across all presets confirms that the RTX 5090 is the primary determinant of frame rate in this title.

CPU Role

The AMD Ryzen 7 9700X provides the processing foundation for this combo, with 8 cores and 16 threads based on the Zen 5 architecture (Granite Ridge). Its base clock of 3.80 GHz and boost clock of 5.50 GHz, combined with 32 MB of shared L3 cache, deliver strong single-threaded performance that flight simulators require for their complex flight models and AI traffic.

The CPU's benchmark results show balanced performance. In Cinebench R23, it scores 31,588 in multicore and 4,459 in single-core tests. The Geekbench multicore score is 17,002, with a single-core score of 3,353. These results place the CPU in the 89th percentile of all CPUs, with an average benchmark score of 36,029. The nearest rival, the Intel Core i5-14500HX, scores 35,940 (0.2% behind), while the Intel Core Ultra 9 185H scores 36,165 (0.4% ahead).

The 65W TDP is notable for a desktop CPU with this level of performance, suggesting efficient power delivery through the AMD Socket AM5 platform. The CPU supports DDR5 memory with dual-channel configuration and 89.6 GB/s bandwidth, which provides sufficient memory throughput for the game's streaming requirements. The PCIe Gen 5 interface with 24 lanes ensures the RTX 5090 can communicate at full bandwidth.

In Microsoft Flight Simulator, the CPU's role is secondary to the GPU but still important. The frame rates at 1080p Low (243.7 FPS) demonstrate that the CPU can feed the GPU fast enough to avoid bottlenecking, even at high frame rates. The smooth scaling from 1080p to 4K across all presets indicates that the Ryzen 7 9700X maintains consistent per-frame processing times, allowing the GPU to be the sole performance limiter. The CPU's 16 threads handle the game's background simulation tasks—weather, AI aircraft, and flight dynamics—without interfering with rendering throughput.
