How to fix blurry textures when entering Saint Denis in RDR2?

Entering Saint Denis was depressing; the streets were just blurry color blocks. I tried killing all background services, but it did absolutely nothing for the loading speed. I used the GamePP NVMe Queue Depth Configuration to expand the queue from 1024 to 2048 and disabled power-saving. CrystalDiskMark showed sequential reads rose from 3200MB/s to 3450MB/s, and RTSS confirmed stable frame times at 14.2-16.8ms.
