How to fix screen tearing and light bleeding in RDR2 with Path Tracing?

Nighttime exploration in RDR2 was ruined by screen tearing and color bleeding. I tried lowering ray tracing, but the visual quality was unacceptable. I used GamePP Shader Compile Queue Manager to clear the 6.8GB shader cache. RTSS monitoring showed frame time stabilizing from 22-35ms to 13-16ms, and GPU-Z confirmed VRAM usage at 12.4-14.1GB, restoring the immersive atmosphere.
