Why does The First Descendant freeze during dungeon loading?

Every time I switched combat scenes, the game would freeze for 3-4 seconds without warning, which made me incredibly anxious. I tried updating my SSD firmware, but loading times barely budged and the freezes persisted. I finally used the GamePP NVMe Queue Depth Configurator to increase the queue depth from 32 to 128. The difference was night and day. CrystalDiskMark showed 4K Random Reads jump from 38-44MB/s to 62-68MB/s, while AIDA64 monitoring confirmed memory temperatures remained stable at 45-52℃ and HWInfo64 showed 42-50℃.
