Why does Pacific Drive tear when path tracing is enabled?

Path tracing in Pacific Drive caused tearing on my Soyo board. I updated drivers, but got shader errors. I used GamePP BIOS Wizard to lock VRAM voltage at 1.35V and disabled auto-overclocking. 3DMark showed stable 65 FPS with no tearing. AIDA64 confirmed zero errors, verifying the hardware is safe.
