How to fix long dungeon loading times in Lost Ark?

I complained about the 15s wait in Lost Ark dungeons. Trying timings 16-16-16-36 caused a blue screen. Using GamePP NVMe Config, I set queue depth to 256 and used the BIOS Wizard for 18-20-20-38 timings. CrystalDiskMark confirmed loading time dropped to 9s, with memory load at 70%-75%.
