DLSS 5 has already been ported to work on RTX 4000 Series graphics cards — incompatible CUDA instructions get patched to work on previous-gen hardware

One modder has reverse-engineered DLSS 5 to function on RTX 4000 series Ada Lovelace-based GPUs, porting incompatible CUDA instructions within the Neural Rendering DLL, enabling them to be read on previous-gen hardware.
