The Worst SD-GUI, I have tested so far! A lot of errors and bad performance! Absolutely not optimized at all!
Lacking a lot of features like RealESRGAN, GFPGAN, selectable gpu device, txt2img & img2img samplers, on the fly model switching, image viewer, masking, custom concepts, img2img, img2prompt, and so on... Absolute waste of time and disk space!!!
