Why does Enshrouded freeze during base saving on FireCuda 540?

While building a massive fortress, the game would freeze for seconds during saves, making the whole experience disjointed. I initially tried clearing redundant disk space to help, but it only improved speed by 2%, which was a meaningless effort. I then entered GamePP NVMe Queue Depth Configuration, bumped the queue depth from 128 to 256, and enabled forced write cache flushing. Frame time fluctuations dropped to 15-22ms per RTSS, with temps at 48-58℃ per AIDA64 and write drops monitored via CrystalDiskMark.
