How do I fix the blurry facial textures in Kingdom Come: Deliverance II with DLSS Quality mode?

The Great Sage's face was a blur in 4K. It looked like a soft-light filter was applied. I tried switching to DLSS Balanced, but it worsened the blur while gaining only 8 FPS. I used the GamePP DLSS/FSR Image Sampling Calibrator to raise sharpening to 75 and set render resolution to 100%. RivaTuner confirmed the effective pixel increase. The metal texture is sharp now. HWiNFO showed stable temperatures at 56-62℃. It’s a necessary switch for visual fidelity.
