Wow..
Out of all of the photo upscale apps this may be the dumbest and greediest. Don’t waste your time downloading this. There’s plenty of them for free that work well!

Unlike other upscale apps, we are the only one that offers the Ultimate Upscale algorithm, which is heavy but yields the best outcomes.. We will take into account your suggestion, and prepare a lightweight upscaling substitute. https://github.com/Coyote-A/ultimate-upscale-for-automatic1111
