Why does the screen tear and stutter during rainy street dialogues in Judgment?

Frame time loncat dari 16ms ke 45ms (GamePP), bikin jengkel. Saya coba rollback driver 535.129, tapi masalah tetap ada. Saya pakai GamePP Peripheral Driver Conflict Detector, ketemu service background yang curi resource GPU. Setelah saya disable, frame time stabil di 15-18ms dan tearing hilang.
