Why does Enshrouded stutter when placing large buildings on a 990 PRO?

I was devastated when my massive fortifications caused constant micro-freezes, totally killing the immersion. I first tried disabling all background indexing services in Windows, but loading times barely changed, and CrystalDiskMark still showed write speeds dropping from 6000MB/s to 1500MB/s. I then used the GamePP NVMe Queue Depth Configuration to sync read/write queue depths to 2048 and enabled the forced cache flush policy. CrystalDiskMark confirmed an 18% boost in 4K random writes, and AIDA64 showed temps stabilized at 48-54℃.
