We're sorry to hear about the performance issue when using brushes, could you please try deselecting "Use Graphics Processor" located under Photoshop's Preferences > Performance, then relaunch Photoshop and let us know if it helps?
Thank you for your response.
I unchecked "use graphics processor" and restarted Photoshop. I was using a Kyle T Webster brush at 250px and the canvas was 300dpi.
The brush still lagged horribly. I could count the seconds it took to complete a stroke.
Please, if you can offer anything else, I am happy to try it. At this point, this is terribly affecting my workflow and I will have no choice but to look into how to downgrade back to PS CC 2015.
Thank you again for your suggestion.
Thank you for providing the information, could you please try enabling the root user account on your mac and let us know if you experience a lag in that account as well? Steps to enable root user: How to enable the root user on your Mac or change your root password - Apple Support
Hello, can you provide the first part (cut before the plug-ins) of help/system info...
Bump, any change, is it working now?
Hi, I'm not sure what you're asking for. Can you give me step-by-step?
Brush smoothing is still slow, but I haven't needed it much since upgrading my tablet.
I haven't had a chance to try it in the root server, but the last time I had a similar PS brush problem, the issue worked fine in the root server. I have to re-install PS in the root server to test it, and restart my computer several times. I just haven't had time.
Hi, what do you mean by the root server? Are you working in a virtual machine?
In Photoshop, go the help menu, click on system info...
