I have 4 gb and it takes about 9 seconds for me :) (Tho at 448x448 but there’s no real difference in quality.)
Good to know it works. That’s not a crap, old, weak gpu, I guess.
I’ve not tried that size but I tried 256x256 and it was too small to get interesting results - maybe there are some parameters that can be adjusted to improve it though.
Not really.

I’m not even sure it works well - if at all - with 4Gb.
In any case, it’s impressive even if it takes minutes. And it’s not like you need to be there to make it work. You can create a list of prompts, let it do its thing and check the results later.
