How to stop severe stuttering when switching maps in Tales of Arise?

The map loading mechanism is unique, but my drive struggled with small files, causing response times to swing between 10-32ms per AIDA64 and freezing the screen. I tried enabling write caching in Windows, but a sudden power outage corrupted my save files. I used GamePP NVMe Queue Depth Configuration to raise read depth from 32 to 128 and optimized the prefetch algorithm. CrystalDiskMark showed random reads rose to 68MB/s and GamePP benchmark confirmed response at 1.2-2.8ms. HWMonitor showed 40-55℃.
