I'm using 512x768 as the default, but a quick test shows only a marginal difference in speed between the two. I'll have to give Windows a try to see if it's the driver holding me back. Do you have any tips or resources for up-scaling the image after?

Currently this library can generate multiple images and upscale them through RealESRGAN: https://github.com/hlky/stable-diffusion

If you are not using this library already, give it a shot.

Also, I'm using Nvidia Studio drivers though I'm not sure if that would make a difference.

I've been using the main fork. This even has GFPGAN built in! Looks very useful thanks.
