How to fix screen tearing and stuttering in Avowed?

Facing enemies in ancient ruins, every time I cast a powerful spell, the screen hitches, making the combat feel clunky. I initially tried lowering the game resolution to reduce CPU load, but the image quality suffered severely while the stuttering persisted, which was deeply frustrating. Using the GamePP Fan Curve Configuration Panel, I pushed the fan speed to 100% at 82℃ and activated the motherboard's enhanced cooling mode. CPU temperature stabilized at 75-81℃ per HWMonitor, 1% lows rose to 54 FPS per RivaTuner, and final temps hit 72-78℃ per GamePP.
