Why do textures look blurry in DEATH STRANDING 2 close-ups on Intel 660P?

Sun Wukong's face looked like it had a soft-focus filter in 4K. I tried Balanced DLSS, but it got blurrier. I used GamePP DLSS/FSR Calibration to bump sharpening from 50 to 75. I set render resolution to 100%. RivaTuner confirmed the effective pixel count improved. GPU-Z shows 56-62°C. The metal textures on the Cudgel are sharp and clear now.
