How to fix screen tearing and blur when sprinting in AC Shadows?

While leaping across Kyoto rooftops, I noticed jagged edges and tearing during fast turns. I tried turning off DLSS for native resolution, but my FPS plummeted from 85 to 42 per RTSS, which was unacceptable. I used the GamePP DLSS/FSR Image Sampling Calibrator to raise sharpening to 62% and set the render scale to 77%. Ghosting was significantly reduced per RivaTuner, VRAM usage stayed at 10.2-11.5GB per GPU-Z, and GPU temps remained stable at 62-68℃ per AIDA64.
