How do I stop texture tearing in The Witcher Remake?

I was frustrated by texture tearing in Velen, which dropped my frame rate to 45 FPS. I tried system defaults, but it failed. I used GamePP to increase NVMe queue depth from 32 to 256. CrystalDiskMark showed 4K random read speed jumping from 80MB/s to 220MB/s, and GamePP Frame Time Analyzer confirmed frame time dropped from 15ms to 10ms.
