Thanks for confirming. Shortly after I ended up reading a ton of articles and it appears it wouldn't matter much anyways, as they were trained at 512x512 resolution to begin with, which makes sense as to limits and images tending to overlap or duplicate when you set the output higher. And you're right, 768x512 is really perfectly fine, I was just curious but knowing more now realize that there wouldn't be much benefit of a 3090 Ti over a 3080 Ti... at least, yet.
