How to fix blurred facial details and metal textures in The Hunt 4K close-ups on Great Wall GW3500 256GB?

When Laura's face appeared in close-up, DLSS Quality mode blurred the fine textures, making the metal staff look like it had a soft-focus filter. I tried switching DLSS from Quality to Balanced mode, which improved FPS by 7 but worsened the blurriness, frustrating me. I used GamePP DLSS/FSR Image Sampling Calibrator to increase DLSS sharpening to 75 and set render resolution to 100%. GPU temperature remained stable at 55-61℃ per HWiNFO64, and in-game frame comparison confirmed significant recovery in sharpness.
