How do I fix the blurry textures and lost details in Palworld at 4K resolution?

At 4K, DLSS Quality mode made character faces look like they had a soft-focus filter, losing all fine texture details. I switched to DLSS Balanced mode, which boosted FPS but made the blurriness even worse. Using GamePP DLSS/FSR Image Sampling Calibrator, I raised the sharpening intensity from 50 to 75 (after testing 90 which caused artifacts) and set render resolution to 100%. RivaTuner confirmed improved effective render pixels, and HWiNFO64 showed stable GPU temperatures at 56-62℃.
