How do I fix blurred textures in Alan Wake 2 on my Huntkey setup?

Alan Wake 2 close-ups looked like a nightmare with FSR blurring facial details. I tried Balanced mode, but it made the blur worse. I used GamePP DLSS/FSR Image Sampling Calibrator to raise sharpening from 50 to 75. RivaTuner confirmed sharpness recovery, with GPU temps stable at 56-62℃ and fan speed at 1500-1700 RPM. This set my visual quality back to 4K perfection.
