Quick answer: The unofficial mod now covers all four main DLSS features on Radeon RX 7000 and RX 9000 cards, according to VideoCardz. It's experimental, Windows 11 and DX12 only, and you supply your own DLSS files.
NVIDIA's DLSS features keep showing up on AMD hardware, and now the whole main set is there. Developer Daniel Blanco has released version 0.8.0 of DLSS-NR-on-AMD, an unofficial project that adds DLSS Ray Reconstruction and DLSS Frame Generation, including Multi Frame Generation up to 4X, on Radeon RX 7000 and RX 9000 GPUs.
Along with the Super Resolution and DLSS 5 Neural Rendering support it already had, VideoCardz says that means all four main DLSS technologies now have working unofficial versions on Radeon. NVIDIA Reflex is the one piece with no confirmed port. The project runs NVIDIA's models through custom HIP compute kernels and DirectX 12, and version 0.8.0 adds a manager called NeuralHub that keeps the needed DLL files in one place and lets you toggle features from an in-game overlay.
Early results are mixed. One Reddit user running Cyberpunk 2077 at 1440p with path tracing on an RX 9070 XT reported no measurable FPS loss with Ray Reconstruction, while others report drops of around 4 to 10 FPS, and another test reportedly showed about a 25% hit. Alan Wake 2, Resident Evil Requiem and Pragmata have been reported as not working so far.
There are some catches. It targets Windows 11 and DirectX 12 games with DLSS, FSR or XeSS support, you have to supply your own DLSS DLL files, and games with active anti-cheat may block it. RX 6000 support is still being tested.
