[ @Ashraf] I knew what I was in for, and because my graphics card was not “enough” to do the hard work, it chose to give that work to the CPU, a FIRST gen Core i7 860. So once it was causing the fan to run hard, I killed the app. I might try it on a 4th gen i5 and see how that goes.
BTW, the clarity of an upscaled (by AI) image (JPEG) was very good, and the reason for giving it a go. It took a 720p webcam photo and turned it into something like a 1080p.
