It’s hard to give precise figures, because there’s always tricks to getting a little more or less but from my (admittedly limited) testing SDXL is significantly more demanding, and 10+GB of VRAM is probably going to be the minimum to run it. I don’t remember exactly what I was doing but I run on an RTX A4500 card, and I managed to max out the 20GB of VRAM just with one SDXL process, where I can normally run a LORA training and 512x768 size images at the same time.
The real value of SDXL isn’t the higher native resolution, its the improvements in rendering fingers and text and so on. But honestly I have not yet been super impressed by SDXL, in the same way that I want to stay playing the old game with all its DLC and mods. SDXL is good, but until we have the same depth of resources available I am staying with 1.5.
Wouldn’t it achieve more to boycott things instead? If you won’t even give up watching a tv show, you aren’t an activist you are just complaining on the internet.
It does seem to work fairly well, although I will say that it doesn’t fit my workflow at all so I haven’t done a lot of testing. I do think there are some UI things that you could look at though. Engine and Dimensions shouldn’t be minimizable lists, because the fields only take up as much space as the label does. Also, your tooltips are outrageously large, covering about 75% the width of a 1080p monitor which makes them quite hard to actually read.
