Upscale by Ai is terrible slow

Almost 6 minutes… only by upscaling 2x…
I am working with iMac and 3,6 GHz 8-Core Intel Core i9

It is not workable. Please make it work faster!

Something to try, please change this setting and test it.
Edit>Preferences>AI Processor the default is “Auto” try your video card, if no improvement with that try the setting “CPU” close the program then reopen after each change for a test.

Report if this helps or not, it made a huge difference on my windows system (more modest CPU than yours). When I changed to my video card Topaz works so much faster I could hardly believe it.


Hello Bill,

Changing to my video card works for Sharpen as well for Denoise. For Ai also for both Sharpen as Denoise, but not for Upscaling. It is a little faster then it was before, but still cost me some minutes to change a photo in Upscaling.


Thats a shame, your system should not be the issue. Hopefully the Topaz team can get this figured out. You are not alone. Its weird how some installs are good and some not.

Thanks for posting as Topaz will hopefully resond to the problem many are having.


Thanks Bill, Hope that they wil fix it asap.
