Sorry it’s been disappointing so far. I don’t have FW16, but I do think people have been successful with running SD on it. If you haven’t seen it, take a look at this guide by @cepth, for example: Installing ROCm / HIPLIB on Ubuntu 22.04 - #2 by cepth
This follow-up thread might contain some clues too: Stable Diffusion / ROCm / PyTorch Setup
Other than that, I’m with you hoping things are going to get better
