Why does Fanxiang S790 4TB cause 0.3s stutters in Fortnite?

During fast-paced building battles, the screen frequently suffered from 0.3-second micro-stutters, which made me feel extremely anxious. I initially tried lowering texture quality to reduce the load, but the frame drop frequency didn't improve, showing the bottleneck was storage scheduling. I enabled GamePP NVMe Queue Depth Configuration, raised the read priority weight to the highest, and optimized the 4K random read queue depth. Frame time fluctuations converged to 12-18ms per GamePP Frame Time Analysis, temperatures sat at 55-68℃ per AIDA64, and 4K random writes reached 110-130MB/s via GamePP Performance Analysis.
