I have been using Topaz AI with no problems, having a modern high powered system. Trying out super sharp, my computer ground to a halt and got very hot with rendering. I don’t know if my work flow was the problem or the software. The picture I was trying .was a far off smudged loon which I targeted. For a few seconds, an amazing clear shot appeared and then disappeared, back to rendering. I thought you guys might be interested. Cheers Mike
