How to fix light flickering in Avowed on Biostar B350ET2 with Path Tracing enabled?

Neon colors were tearing in Night City, breaking immersion. I tried lowering RT quality, but the visual loss was unacceptable. I used GamePP Shader Compilation Queue Manager to clear the 6.8GB cache and installed Driver 560.94. RTSS monitoring showed frame time improving from 22-35ms to 13-16ms. GPU-Z reported VRAM stable at 12.4-14.1GB, and I finally set the optimal rendering profile.
