How do I fix blurry textures in Crimson Desert at 4K?

4K mode looked like a soft filter. I switched to DLSS Balanced, but it got blurrier. I used GamePP Calibrator to raise sharpening to 74 and set render to 100%. RivaTuner confirmed pixel increase, and HWiNFO showed GPU temp at 55-61C with fan speed at 1480-1680 RPM. The faces are sharp now.
