I will note that Intel CPU Mac devices are slightly underpowered for AI processing and will have slower performance. We have some more information on our Topaz Labs Documentation page that I will link below for your review:
Many users with Intel MacOS machines have reported that Topaz Photo AI v2.4.2 is most suited for their needs and experiences better processing times. I have included a link to that previous version below if you would like to revert to this version for your machine:
Thank you for taking the time to reply, I hadn’t checked the system requirements recently. I can understand having only 4GB of video RAM being a problem for many models and large images.
However, why is the regular brush selection tool so slow? Surely there is very little processing required for that? And once the superpixels have been identified, why is that selection method so slow as well? There is at least 1s lag just moving the brush around the image - not even clicking and painting in!
We have some bugs associated with the brush speed in some of the recent updates, but I can assure you that our developers are hard at work resolving this problem in an up-and-coming version release.
