How to fix texture pop in The Division Next?

Moving through city outskirts, buildings turned into pixel blocks. I tried increasing page file, but FPS dropped from 78 to 61. I used GamePP BIOS Voltage Regulator to set timing 16-18-18-36 and 1.30V. AIDA64 confirmed latency dropped from 102-115ns to 76-82ns, and VRM temp stayed at 58-63°C.
