The first game with official DLSS 5 support, NBA 2K27, came out recently, and modders quickly took the DLSS 5 DLL file from the game and made it available to gamers around the world who own a newer NVIDIA GPU, allowing them to use DLSS 5 in a bunch of PC games with tools such as OptiScaler and DLSS 5 Swapper. While only the RTX 50 series is officially supported, at least for now, the two aforementioned utilities allow you to use DLSS 5 on older NVIDIA graphics cards as well.
