Why are level loads so slow with black screens in Unknown 9: Awakening on the YMTC TiPro9000?

Loading screens lasted forever, breaking immersion. I tried closing background processes, but load times only dropped by 2 seconds. I used GamePP NVMe Queue Depth Configuration to increase the queue from 512 to 1024. CrystalDiskMark confirmed sequential reads jumped from 7000MB/s to 7300MB/s, reducing load time to 3 seconds with drive temps at 50-55℃ per GamePP.
