Why does Raft have a 2-second black screen when switching to dungeons on Kingston HyperX FURY?

Switching to dungeons felt fatal due to a 2-second black screen. I tried updating the chipset driver, but the lag remained. I used the GamePP Peripheral Driver Conflict Detector and increased NVMe queue depth from 512 to 1024. I/O latency dropped from 15ms to 8ms per CrystalDiskMark. Drive temperature held at 45-50℃. The loading is now instant and smooth.
