Eliminate DLSS Over-smoothing
It was unbearable; at 4K, the neon lights of Night City were blurred and metallic textures vanished due to DLSS. I tried switching DLSS to Balanced mode, but while I gained 10 FPS, the blurring got even worse. I used the GamePP DLSS/FSR Image Sampling Calibrator to raise sharpening from 50 to 78 and locked the render scale to 100%. Street textures became sharp again per RivaTuner, and VRAM temperatures stabilized at 50-60°C per GPU-Z with 2500MHz stable per GPU-Z.
