Why are textures loading slowly in Nightingale on Sapphire RX 590 8G D5?

Entering new zones felt painful with 3.2s texture delays. Updating the driver crashed my system, making things worse. I used GamePP Driver Conflict Detector to find the issue and set queue depth to 512. Loading time dropped to 1.8s, and GPU temp held at 75-78℃, making exploration fluid and responsive again.
