DLSS 5 officially debuted inside NBA 2K27 yesterday with more games to follow down the line, along with RTX 40-series support planned for the future. However, if you don't own a GPU from either of those families, the modding community has once again stepped up to offer a workaround. Developer danielblnc has figured out a way to make DLSS 5 work on AMD's RDNA 4 GPUs (RX 9000 series). As long as you're playing a DirectX 12 game with FSR support, "DLSS-NR-on-AMD" can inject DLSS 5 inside it.The project is closed-source, so we don't know exactly how it works but we can make a few educated guesses. The mod is likely using a dynamic wrapper to intercept NGX API calls and fool the DLSS 5 DLL into loading on an AMD GPU. Once loaded, it extracts the AI model and Tensor data inside that DLL and converts those calculations into math AMD's matrix accelerators can understand via the HIP RT backend (rather than translating CUDA).It then hooks into the game's FSR pipeline to run that frame data through the neural model and produce the same quality results you would get on an actual RTX 50-series GPU, just without any of the Tensor cores. DLSS-NR-on-AMD doesn't work on any game requiring anti-cheat. Even in single-player titles the performance is not great, especially since the RX 9070 XT is the top-end RDNA 4 GPU available.Initially, Cyberpunk 2077 was running at 28 FPS at 1080p on the 9070 XT with DLSS 5 on, but a patch has been released that improves the frame rate by 12% to a stable 30 FPS. Another update has added a 2% boost but that's likely negligible. Performance reports from users online are a bit less optimistic. The ultimate goal is to get performance similar to an RTX 5070 Ti, which is not far-fetched since both GPUs are matched in raster and very close in ray tracing.
