Slow generation speed #40

Open healthyfat opened 2 weeks ago

healthyfat commented 2 weeks ago

I am having a problem with very slow generation speed when using AutoCFG. Wonder if this might have anything to do with below warning or is it just my 6GB VRAM to little for this node?

Hello! Unfortunately I can't really tell like this. You message is about something else and the iteration speed, while slow indeed, may come from anything.

You right. That warning is not due to AutoCFG. I will just mention that after I cancel the process and start it again then it works normal as on example below.

Sometimes while using comfy the first time that a set of parameters is used for some reason I get a slowdown too. Now I'm not sure about your setup.

Setup? You mean my hardware or Comfy? I use GeForce 2060 6GB.

ComfyUI can automatically switch into low vram mode.

try to start the UI with the --normalvram argument
