I applaud the Photo AI 4.0 beta Dust & Scratches feature. However, it still needs a lot of learning and refinement.
In my trials I can see some dust and scratches (white specs and lines) fixed, some others ignored, and some inappropriately accentuated. The tool within the module to stroke additional spots/lines doesn’t seem to result in additional repairs; my trying is ignored. Example attached (4380x3200 pixels). The interface to submit here seems to have reduced it to 850x620.
I saw the notification of the new release 4.0. I took a try and downloaded/installed, and it works. I’m pleased that this update/upgrade from 3.6 was available to me. I had only expected dot-releases. 
I read about new Dust & Scratches repair needing 8 GB VRAM requirement, but took a try locally anyway with my card which only has 4 GB. Although it ran slowly, it did execute. It didn’t bomb out as the early beta for remove object would.
I can see a little bit of dust and scratch repairs, but even with stroking a few additional spots within the tool I don’t see as much improved as I would expect.
As blurry as my original is, the face and hair improvements are amazingly good. Thanks, TopazLabs!
@rberke - Thanks, as this is the first release of this tool, make sure to send the original and current results you get, with the list of what you wish the tool would do, to support@topazlabs.com and we can relay to the development team to help make the tool better over time! For this file, I would crop out the white thick edge and solely focus on the picture part, the outside edge would take a lot of manual work to restore, in another program such as Photoshop.
