Why are textures blurry in Ghostwire Tokyo racing scenes on Ryzen 5 9600X?

High-speed corners in Ghostwire Tokyo looked like a soft-focus mess due to DLSS Quality mode. I tried switching to Balanced, but the blurriness got even worse. I used GamePP DLSS/FSR Image Sampling Calibrator to raise sharpening from 50 to 75. RivaTuner confirmed sharper details, and AIDA64 showed stable 52-58℃ temps.
