@ Tim and Paul
I did more testing on this today. In the latest release of CC 2023 I can replicate you results and it is much slower. In the latest release of CC 2022 it is still as fast as it has always been. In my testing on a Macbook M1 mini, I am getting 11 seconds in CC 2023 and 5 seconds in CC 2022.
I really have no idea why CC 2023 is so much slower and I don’t know of anything I can do to speed it up. I may have to work with Adobe on it but I have no idea if they can speed it back up and when that could happen.
So I guess my best advice is to run EZ Green Screen 7 in Cc 2022. You can have both CC 2022 and CC 2023 installed at the same time so you don’t need to uninstall CC 2023.
I know this isn’t ideal. However, I don’t work for Adobe so my hands are tied when things in Photoshop itself run slower. Really, the only thing I can do is relay the information to Adobe and hope they improve it.
