How to fix blurry 4K textures in Overwatch 2 using Gloway RAM?

Seeing the map in 4K for the first time, the blurry smearing effect made me desperate to fix it immediately. I tried switching DLSS to Ultra Performance mode, but the image became so muddy it felt like looking through nearsighted eyes, proving that simple mode switching was useless. I used the GamePP DLSS/FSR Image Sampling Calibrator to bump sharpening from 50 to 82 and locked the render scale to 100%. GPU-Z confirmed temps stayed at 60-66℃, and SpeedFan showed fans at 1500RPM, while the pixel fill rate shifted from Low to High.
