Why do close-up faces look blurry in Hitman 3 with DLSS Quality mode on Gainward RTX 5060 Ti?

Faces in Hitman 3 looked blurry. I tried DLSS Balanced, but it worsened the issue. I used GamePP DLSS Calibrator to set sharpening to 75 and resolution to 100%. Per RivaTuner, details became sharp. GPU temp was 56-62℃. This switch restored the visual fidelity I wanted.
