DLSS 5 uses NVIDIA's model (nvngx_dlssnr.dll beside the game) on the cards NVIDIA supports.
It is a separate download: PC settings > Video > Download DLSS 5, or the launcher's offer.
For other cards, put a DLSS 5 model build made for your card in this folder as
nvngx_dlssnr.dll. Updates never replace a file here.
