How to fix SLC cache overflow stutter in DS2 on Manli Nebula RTX 5060?

I panicked when DS2 loading hit 10s, with CrystalDiskMark showing 55-60MB/s 4K reads. Increasing virtual memory made it worse. I used GamePP NVMe Queue Depth to raise depth from 1024 to 2048. CrystalDiskMark verified 4K reads improved to 75-80MB/s, loading dropped to 4s, and drive temp held at 48-55°C.
