I get that when it is doing its thing, Photo AI is going to use a lot of CPU time, memory, and other system resources, and my computer is otherwise going to be slow and boggy for anything else I try to do on my computer, while I am processing a large image in Photo AI.
But just now, after I finished processing an image, and had closed it, my computer was still being slow and boggy. I had closed the image in Photo AI, and at that point, it ought to have been sitting idle, using up just barely what resources it took to keep it loaded and ready for the next use.
My computer was still being slow and boggy, and when I checked the Task manager, I saw that Topaz Photo AI was still hitting my CPU usage hard, taking up 50% to 75% of it, for no reason that I can think of. There was no image loaded into it, at the time, nothing for it to be processing, no reason for it to be using any significant amount of CPU time.
On doing an “End Task” on it from Task manager, it was terminated, of course, and my computer immediately recovered to normal performance.
I’ve faintly noticed similar issues in the past, regarding this and other related Topaz products (Denoise, Sharpen, Gigapixel), but this is the first time I took the effort to “catch” it, document it, and report it here. The screen shot shows Topaz Photo AI taking up 51% of the CPU, which is near the low end of what I observed watching it for several seconds. I had just finished processing a large image, several minutes before, and has closed that image in Photo AI, so the program should have just been sitting idle, not using any significant CPU time at all.
