Why is Ghost of Tsushima PC version tearing and bleeding?

Neon areas in Path Tracing had bizarre color bleeding that ruined immersion. I tried lowering RT to High, but the visual drop was unacceptable. I used GamePP Shader Compilation Queue Manager to clear the 5.5GB cache and installed NVIDIA Studio Driver 560.94. RTSS monitoring showed frame times converging from 20-32ms to a stable 12-15ms, while GamePP confirmed VRAM usage stayed within 11.2-13.5GB.
