All the different number selections in the UI are a bit confusing for me.

I don't really understand the idea of a percentage resize first and a multiplication factor upscale afterwards. If I have 512x512 images, which settings should I select to upscale them to 2048x2048?  Would I choose 100% resize with a 4x upscale factor or would I choosea  %200 resize with 2x upscale factor? - or shouldit be something different?

For example, if I want the images to be twice as big as the original - would I choose 100% bigger or 200% bigger? Then when I upscale it, what size would 4x be? Would it be 4x bigger, or 4x 200% bigger. I just don't get it.

Also, I don't understand the RAM specification - is is asking for VRAM or System RAM - or both combined?

Either way, I've tried many different settings and the upscaled results are exactly the same as the original images = 512x512 and it adds a watermark to the image saying "upscaled with github.com". It also adds all the images to the source folder so it's a compete mess after it's process the files because it keeps the original, adds a converted file and a resized file.

Thanks.
