How to stop Crimson Desert map loading stutter on Great Wall?

I complained about experience degradation caused by low-level hardware issues in Crimson Desert's map system. I tried manually overclocking to 7200MHz, but the system blue-screened and restarted, failing the aggressive strategy. I then found the NVMe controller queue depth was too conservative. I entered GamePP NVMe Queue Depth Configuration and increased the queue depth from 32 to 256 on my Great Wall GW3500 512GB M.2 NVMe SSD.
