How do I fix blurry textures in KCD2 with DLSS Quality?

KCD2 close-ups looked like a blur in DLSS Quality mode. I switched to Balanced, but it got worse, losing even more detail. I was frustrated. I used GamePP DLSS/FSR Sampling Calibrator to boost sharpening to 75 and set render resolution to 100%. Per RivaTuner, effective pixels increased, and GPU temps held at 56-62℃. The metal textures are sharp again. I switched back to Quality with confidence.
