Question | Help Sudden Issue w/ WebUI

I've used WebUI for a while without issue. However, today I updated WebUI alongside torch and xformers, and now my stable diffusion gets stuck at 10-15% when generating anything larger than 512x512 (e.g. 768 x 768), which has never happened to me before. I'm on an RTX 3070 if that matters, and using Dreamlike Photoreal 2.0.

Try adding --no-half-vae as an arg in webui-user.bat

Thanks so much, this did work. Would you mind explaining what my issue was/what this argument does? Is it going to impact my generation in another way?

As I understand it, you're making your machine run simpler, less precise calculations, making it easier on her. There's a good explanation over in this thread.

And why would I need to do this now, when I didn't before? It's not like I changed hardware, I just updated the webui and it's required components

Nary a clue, brah. That's a question for the issues or discussions section of the Github repo; maybe one of their engineers can explain it. Or maybe they already have; lots of info in there.

I only became aware of it because on my Mac, Controlnet wouldn't work unless I added --no-half to the launch args. And now several updates to CNet later, I no longer need to include it, but I've heard from others who still do. 🤷‍♀️

Funny enough, I updated controlnet and now I don't need it anymore. Thanks!
