>>69902595Details get better at higher resolution. That's what highres fix is for (on SD1.5 at least. There's no need for highres fix on XL). If you don't have the VRAM, you can upscale in bite-sized tiles with SD Ultimate Upscale (Tiled Diffusion uses the same principle but is more VRAM hungry)
Unless you're doing pixel art, you're probably gonna want to do 1.5x or 2x upscaling on those puppies.
