'We do not support Intel HD Graphics 4600 integrated graphics cards or lower in any configuration.' If I understand correctly, your GPU is an integrated GPU, not dedicated, and so uses the computer's RAM for the video memory.
Looks like you might have an incompatible graphics card for Topaz imaging apps. Thanks for your reply Ian, I'll check to see if it's up to date. You could try updating the graphics driver. I have run diagnostics on the computer and it says everything is running healthy. Is it possible there is a problem with my computer or the software.
I know the Intel iRIS Xe integrated graphics card isn't as good an option as a dedicated graphics card but I would have thought it would be easily capable of handling Processing a single photograph. The Processing takes so much longer when set to to CPU. I have to run the processor set to CPU in preferences for it to run without the pop up Error. When using Topaz Sharpen Ai with the Topaz Ai processor set on Auto I'm constantly getting a pop up saying Processing Error. Given my computer was quite old I also purchased a new Dell Inspiron 15- i7 with 16gb Memory and a Intel iRIS Xe graphics for my Photo processing. I recently purchased Topaz Sharpen Ai and On1 Photo Raw 2022.
