Why does Unknown 9: Awakening flicker with Path Tracing on Crucial DDR4 3200MHz?

Neon lights in Night City looked like a broken CRT. Lowering RT to High killed the visuals. I used DDU to clean install driver 560.94 and GamePP Shader Queue Manager to clear 6.8GB cache. RTSS showed frame times dropping from 22-35ms to 13-16ms. VRAM stabilized at 12.4-14.1GB via GPU-Z. The visuals are finally crisp and stable.
