Why are Atomic Heart load times slow on WD SN750 SE?

Atomic Heart loading delays were a pain. I tried tightening timings to 16-16-16-36, which caused a BSOD. I then used GamePP NVMe Queue Depth Configuration to set depth to 256 and the BIOS Wizard to set timings to 18-20-20-38. CrystalDiskMark confirmed the storage boost, and load times dropped to 9 seconds. This stability allows me to backup my progress without worrying about long wait times.
