Why does Hollow Knight: Silksong stutter during map transitions on Great Wall GW3500 512GB?

I felt the immersion break instantly when the Great Wall GW3500 512GB SLC cache overflowed, dropping write speeds from 3500MB/s to under 500MB/s. I tried increasing virtual memory, but it only worsened disk conflicts. I then used GamePP NVMe Queue Depth Config to raise the queue from 512 to 1024 and enabled forced write cache flush. CrystalDiskMark verified 4K random read improved from 35-42MB/s to 55-62MB/s, and HWiNFO showed stable 40-48℃ temps. Load times dropped from 8s to 3s, finally letting me enjoy the game without lag.
