Ive never seen any posts from AMD owners, slating their DLSS, which is done via software.
Because there isn't any reason complain? It works perfectly providing superior image quality at 4K from higher base resolution like 1800p, than any NVidia card using DLSS except the 2080Ti which are in par.
And is game agnostic, assuming is DX12 game, while DLSS is applied on handful of games only.
