How to stop blurred textures in UE5 Matrix Tech Demo on 990 PRO?

Running the Matrix demo in 8K was a nightmare; high-precision textures emerged slowly like pixel blocks. I first tried enabling 'Ultimate Performance' mode in the driver, but loading only improved by 1 second—a total joke. I then switched to GamePP NVMe Queue Depth Configuration and increased the read queue depth from 64 to 128. The difference was night and day. 4K random reads jumped from 45MB/s to 72MB/s per CrystalDiskMark, while temps remained a cool 45-55℃ per HWMonitor and reads hit 40-60MB/s via CrystalDiskMark.
