Fixing 4K DLSS Blur
Face close-ups looked soft and blurry in DLSS Quality mode, losing fine hair details. I tried switching to DLSS Balanced, but it made the image even worse, which was frustrating. I used GamePP Image Sampling Calibrator to raise DLSS sharpening from 50 to 75 and set render resolution to 100%. RivaTuner confirmed effective render pixels increased, and HWiNFO showed GPU temps stable at 56-62°C.
