6600XT reporting in. Spent a few hours on Windows and WSL2 setup attempts, got no where. I don't run Ubuntu at home and don't want to dual boot just for this. From looking around I think I'd have a better chance on native Ubuntu.
Or wait, if its just about stable diffusion multiple people try to create onnx and directml forks of the models/scripts, which atleast in theory can work for AMD gpus in windows and wsl2
