How to stop texture popping in World War Z: Aftermath?

Sneaking through ruins was a nightmare because distant textures kept jumping between blur and clarity. I first tried formatting the partition and re-aligning 4K sectors, but the flickering persisted, which was beyond frustrating. I finally ran the GamePP Peripheral Driver Conflict Detection Tool and found a nasty I/O contention between the NVMe controller and an old USB driver. After disabling it, RivaTuner showed frame time fluctuations drop from 16-35ms to 10-14ms, PCIe 4.0 response hit 22-40ms via CrystalDiskMark, and temps sat at 46-53℃ per AIDA64.
