Photoshop + Mac Pro 2013 useless Performance [2020]

Question

Hello there, I hope you are all doing well.

It's been a while Photoshop performance on my Mac Pro 2013 has gone down the drain. I've tried all the options that I could find in the community, but none of them seems to work. Photoshop (Also illustrator) is absolutely useless. It doesn't matter the file size, it seems that I'm always dealing with massive files. I've tested it on Macbook Pro's and it's fine, especially on the newest ones.

Has anybody ever come across such issue?

Thank you.

I have same kind of problems.

The Mac pro 2013 has two GPU's in Crossfire. The first slot (slot 1) is usually reserved for computational tasks - if I have read things right. The slot 2 is for displays etc.

Photoshop goes to slot 2 and occupies the slot 1 also - but does NOT get any resources even when I do filter previews, etc to images. Utilization 0%.

I have checked preferences:

tools: turned off flick panning, gestures, zoom animations

performance: multithreaded compositing (off, because graphical artifacts), advanced settings: OpenCL off, and anti-aliasing off.

Those help a LITTLE but the overall performance of the application is abysmal.

Is there any options to downgrade from Monterey to High Sierra and somehow get the older Photoshop via Adobe Cloud services, since I am a subscriber..?
