How to fix random read latency in DEATH STRANDING 2 on Ti600 2TB?

I felt the immersion shatter when characters lagged during jungle taming. I tried restarting, but I/O wait spiked to 45μs. I used GamePP to raise queue depth from 32 to 128. CrystalDiskMark showed 4K writes jumping to 580MB/s, stabilising the frame rate. Drive temp held at 42-48℃ per GamePP sensors.
