Why does Kingdom Come: Deliverance II have texture pop-in on Ryzen 5 5600?

Texture pop-in was ruining my KCD2 sessions; latency hit 102-115ns per AIDA64. Increasing page file size dropped FPS to 61. I used GamePP BIOS Load Line Voltage Regulator to tighten timings to 14-16-16-32. Latency dropped to 76-82ns, and MemTest86 confirmed zero errors. The world loads instantly now, fixing my frustration with slow streams.
