The combination of a 94th-percentile CPU with a 92nd-percentile GPU yields a system that ranks 14th overall in this game — a synergistic outcome where neither component drags the other down. The measured FPS data across all twelve configurations (three resolutions × four settings) shows no sub-84 FPS averages at 4K, which is remarkable for a flight simulator known for demanding both CPU and GPU resources.

GPU Role

The RTX 5090 D brings substantial graphics resources to this title. It features 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of memory bandwidth. The GPU operates at a base clock of 2017 MHz with a boost clock of 2407 MHz, with memory running at 1750 MHz (28 Gbps effective). These specifications translate to a pixel rate of 423.6 GPixel/s and a texture rate of 1,636.8 GTexel/s, with FP32 performance rated at 104.8 TFLOPS.

In Microsoft Flight Simulator, the GPU's role varies significantly by resolution and settings. At 1080p Low, the system achieves 236 FPS average — a frame rate that suggests the CPU is doing the heavy lifting, as the GPU has ample headroom at this resolution. However, at 4K Ultra, the average drops to 84 FPS, indicating the GPU is now the limiting factor. The 32 GB VRAM capacity is more than sufficient for this title's texture and geometry demands, even at 4K with Ultra settings.

The 170 RT cores and 680 tensor cores in the 5090 D provide hardware acceleration for ray-traced effects and DLSS features, though the measured FPS data does not distinguish between native rendering and upscaling paths. The GPU's 21,760 shading units and 176 ROPs ensure that even the most complex flight scenes — dense urban areas, detailed aircraft models, and weather effects — can be rendered without geometric bottlenecks.

Comparing the GPU's measured performance in this game to its benchmark scores, the 5090 D's 92nd-percentile ranking among all GPUs is consistent with its observed behavior here. The 1.1% gap to the RX 6650M XT in aggregate benchmarks does not manifest as a meaningful difference in this title, where the 5090 D's memory bandwidth and shading throughput dominate.

Resolution Scaling

The FPS progression from 1080p to 4K reveals clear scaling patterns and identifies the limiting component at each step. At Low settings, the average FPS drops from 236 at 1080p to 205 at 1440p (a 13.1% decrease) and then to 151 at 4K (a further 26.3% decrease from 1440p). The 1080p-to-4K total drop of 36.0% suggests the GPU is not heavily taxed at low settings, with the CPU likely constraining performance at lower resolutions.

At Medium settings, the scaling is similar: 198 FPS at 1080p, 159 FPS at 1440p (a 19.7% drop), and 118 FPS at 4K (a 25.8% drop from 1440p). The 4K-to-1080p ratio here is 59.6%, indicating the GPU is becoming more involved but still has headroom at 1080p.

High settings show a steeper 1080p-to-4K decline: 149 FPS at 1080p, 120 FPS at 1440p (a 19.5% drop), and 88 FPS at 4K (a 26.7% drop from 1440p). The 4K average of 88 FPS represents 59.1% of the 1080p figure, confirming that the GPU's workload scaling is consistent across settings presets.

Ultra settings exhibit the most pronounced resolution sensitivity: 142 FPS at 1080p, 114 FPS at 1440p (a 19.7% drop), and 84 FPS at 4K (a 26.3% drop from 1440p). The 4K-to-1080p ratio of 59.2% is nearly identical to the High preset, suggesting the GPU is the primary limiter at 4K regardless of settings tier.

The data indicates that at 1080p, the system is likely CPU-bound, as the i7-14700K's 20 cores and 28 threads are taxed by the simulator's complex flight models and scenery generation. As resolution increases, the GPU becomes progressively more dominant, with the 4K results showing clear GPU-limited behavior where the 5090 D's capabilities define the ceiling.

Settings Recommendations

For 1080p displays, the Low preset at 236 FPS average provides the highest headroom for competitive or high-refresh-rate gameplay, though the Ultra preset still delivers 142 FPS average — well above the 144 Hz threshold. The Medium preset offers 198 FPS with a measured minimum of 168 FPS, ensuring smooth frame delivery even in demanding scenes. For most users at 1080p, the High preset at 149 FPS average strikes the optimal balance between visual fidelity and performance, as the difference between High and Ultra (7 FPS) is minimal relative to the settings cost.

At 1440p, the High preset delivers 120 FPS average, which is the recommended configuration for users with 120 Hz or 144 Hz monitors. The Ultra preset at 114 FPS average is also viable if visual quality takes priority, with only a 5% performance penalty versus High. The Medium preset at 159 FPS provides substantial headroom for users with higher refresh rate displays, though the visual step down from High is noticeable in a game known for its scenery detail. The Low preset at 205 FPS is only recommended for competitive or maximum-frame-rate scenarios, as the visual compromises are significant.

For 4K displays, the Medium preset at 118 FPS average with a 100 FPS minimum is the best choice for maintaining smooth gameplay, as it provides a comfortable margin above the 60 FPS threshold. The High preset at 88 FPS average is acceptable for users prioritizing visual quality, though the 100 FPS minimum of Medium offers more consistent frame pacing. The Ultra preset at 84 FPS average is the most demanding configuration tested, but the sub-90 FPS average may introduce perceptible judder on 120 Hz displays. The Low preset at 151 FPS average is the only 4K configuration that fully saturates high refresh rate panels, but the visual downgrade is substantial.

The data shows that the Medium preset at 4K offers the best compromise for this system, as the 118 FPS average with a 100 FPS minimum provides both high visual quality and smooth performance. At 1440p, High is the sweet spot, and at 1080p, High or Ultra both deliver excellent experiences.
