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

Close-up faces looked soft and blurry in DLSS Quality mode. I tried switching to Balanced mode, which increased FPS by 8 but made the blurriness worse. I used GamePP DLSS/FSR Image Sampling Calibrator to raise sharpening intensity from 50 to 75 and set render resolution to 100%. RivaTuner showed effective render pixels increasing, and GPU temp stayed at 56-62℃, confirming the switch.
