Thanks for showing this tool. I will have to try it out also...

This was using the new Topaz Photo AI (latest version 1.1.9) not Topaz Sharpen. 
I noticed that the texture in the shirt (3rd from right), for instance, is 
better with Codeformer. Hence, Codeformer seems to do better, with not just 
faces, than Photo AI. I went back and tried adjusting things in Photo AI to no 
avail. I could never get the shirt right.

I have notice with Topaz AI tools that the image resolution can make a 
difference. For larger images, such as A7Riii or A7Riv, the results have a lot 
of artifacts but if the image size is reduced, the artifacts become less. I was 
wondering if the AI model training does not include such high res images. And 
if the image is already fairly sharp, Denoize Clear seems to do better and is 
much faster.

I'm curious if Codeformer has a similar issue with resolution?
