Tools Lagging

Me too, I really hope Adobe can realize the lagging issue, I am sure that  my system and hard-device can afford the Photoshop's requirement. But the  software works so laggy, no matter zooming the canvas , scroll the Brush selecter list , or putting brush strokes, meeting with low FPS and high latecy.I use RTX 4090  ,with 64G RAM ,7950X CPU . When the software get slow， the usage of my  computer performance actually stay quite low level , that means the it seems that the Photoshop is not making full use of  the system performance.

Unfortuantely resetting the tools did not fix it

Have you tried resetting the tools? If you select a tool, in the Optoins Bar select the tool option and click on the dropdown menu icon. Click on the Gear icon and from the menu, choose reset tool, or reset tools and see if that might help.

From what you are saying and other posts I am seeing in the community, it seems that Photoshop and Sequoia are not playing well together yet.

I am hoping someone else will chime in here, because I am not on Sequoia and do not have an other options for you.

Let me know if resetting the tools helps or not--

Not besides Photoshop

I mean other than the OS!

Did you upgrade anything before this started happening?

MacBook Pro 16 in 2019

Not M1 - 2.6 GHz 6-Core Intel Core i7

Yes specs fully compatible, never an issue before now

About 300GB free out of 1TB

Hi|

A coupe of questions for you:

What machine are you using?

Are you using Rosetta or native with m1?

When you upgraded, did you check to make sure that your machine and graphics processor card were compatible with the new version of Photoshop?

How much empty hard drive space do you have available on your working machine? Do you have a scratch disk attached?

Also, here is a help doc that gives info on kown issues in Photoshop: https://helpx.adobe.com/photoshop/kb/known-issues.html#cursor-stuttering

Does it seem like your mouse is stuttering? Check out that option in the known issues link above and let us know if that helps?
