I just upgraded my photoshop and it looks very slow and heavy for the System. 
had someone found and solved this kind of problem.

The same happened for illustrator.

I work with a macbook pro

macOS Mojave

2,9Ghz core I7 

16 gb ram lpddr3

Radeon pro 560

    Hi there,

    That does not sound good, as Photoshop is performaing slow, could you please try enabling "Legacy compositing" located in Photoshop's Preferences > Performance, then relaunch Photoshop and let us know if it helps?

     

    You may also try optimizing the performance of Photoshop by following the steps mentioned here: https://helpx.adobe.com/photoshop/kb/optimize-photoshop-cc-performance.html

    I have also the same problem. It is HUGE difference on Mojave. And "Legacy compositing" is not the solution.
    Time lapse video from 793 jpeg images at ~1,7 mb each

    Mac Pro (Late 2013) on macOS Catalina 10.15.7 , 3,5 GHz 6-Core Intel Xeon E5, 32 GB 1866 MHz DDR3, AMD FirePro D700 6 GB

    It takes about 3 minutes 40 seconds


    Mac Pro (Mid 2010) on BootCamp Windows 10, 2 x 3,33 GHz 6-Core Intel Xeon, 48 GB 1333 MHz DDR3, Radeon VII 16 GB

    It takes also about 3 minutes 40 seconds

     

    On same machine on Mac side on macOS Mojave 10.14.6 ,  it takes A WHOPPING OVER 9 minutes 25 seconds

    With "Legacy compositing" it takes about 8 minutes 50 seconds.

    This is UNACCEPTABLE!

      Hi, Photoshop CC20 and Bridge 20 are ridiculously slow (taking 15-20 seconds just to rename a file!) on my mac pro which has 48gb Ram, I've just gone back to CC19 on PS and Bridge and everything is fine. There clearly is a problem

        Just posted a thread about this very same thing! Upgraded the workstation to a 24 core, 64gb of ram, ssd drives and 11gb of vram and photoshop literally stutters. There's something going on with the software!

          You have more than enough machine to handle Photoshop. What is the problem?
