Why does Alan Wake 2 stutter during Dark Place transitions?

I felt my immersion collapse instantly when the screen stuttered during scene transitions. I tried disabling hard disk hibernation in system power management, but it didn't stop the lag and just increased standby power by 2W per HWiNFO. Then I used GamePP NVMe Queue Depth Configuration to manually adjust the depth from 128-512 to 1024 and optimized the write refresh strategy. CrystalDiskMark confirmed 4K random reads rose from 62 to 88 MB/s, and AIDA64 showed temperatures stable at 50-56℃.
