Just recently I did a performance test Of Painter 23 and got an image of the Graphics GPU being inoperative in the test results.
This is new as I had done the test when I first got 23 and everything seemed proper. During a beta cycle awhile back, this had come up before. And as I recall, there is a fairly simple fix. Any suggestions. Above is my system. Thanks in advance.
Can you try changing your color profile, we know that in an OS update there were issues with some color profiles impacting performance. Here is a link to an older post about what the user did to get better results. Let me know if this helps or not.painterfactory.com/.../painter-2021-slow-performance-in-macos-catalina
