I have stopped using Studio because the results are terrible. It is time Topaz got their act together to fix the problems we have, instead of introducing new problems with new plugins.
Studio is a major problem in itself. I liked it very much. The concept is great. But, it is reducing quality in photos, and that is only what I have seen. If it is reducing quality in the original, then, what else...
Fix Studio first, please Topaz, before you introduce any more plugins that will only be updated for Studio. That is not fair and just to your subscribers of many years.
At present I will not use Studio because it ruins my photo to begin with. I use the Legacy plugins because I know they work as they should - apart from Simplify.
