How to fix blurred facial details in RDR2 with Intel i5 12400F?

Cowboy close-ups in RDR2 looked blurred due to DLSS Quality over-smoothing on the Intel i5 12400F. I tried switching to Balanced mode, but the blurring worsened significantly. I entered GamePP DLSS/FSR Image Sampling Calibrator, increasing sharpening intensity from 50 to 72 and setting render resolution to 100%. Frame generation time stabilized at 14-16ms (RivaTuner). GPU temperature remained at 55-61℃ (HWiNFO), successfully switching to sharp visuals.
