How do I fix Tomb Raider DLSS blurriness and texture smoothing on JGinyue X99M-PLUS D3?

Close-ups in Tomb Raider looked like a soft-light filter, losing all metallic detail. I tried DLSS Balanced mode, but it got blurrier. I used the GamePP DLSS/FSR Image Sampling Calibrator to set sharpness to 75 and render resolution to 100%. Per RivaTuner, effective pixels increased, and HWiNFO showed GPU temps at 56-62℃. The visuals are crisp now.
