How do I fix blurred textures in Far Cry 6 on Great Wall GW3500 with DLSS?

Faces looked soft in 4K. I tried DLSS Balanced, but blurriness increased. I used GamePP DLSS/FSR Calibrator to set sharpening from 50 to 75. RivaTuner verified GPU temp stayed 56-62℃ while textures became sharp, switching the visual quality up.
