Question

Photoshop Beta 27.4 running slowly

Since updating this morning, Photoshop beta running very slowly on my machine.

Simple features such as lasso and patch tool are lagging. 

 

Problem not fixed by closing and re-opening application or by restarting the machine.

Was working perfectly with no issues before this update.

Hi @OddShoe do you see the same slowness with Ps release version or just Ps Beta?

 

1. Try resetting Prefs for the Beta:
/Users/yourname/Library/Preferences/ Photoshop Beta Settings (Mac Ventura)
/Users/yourname/Library/Preferences/Adobe\ Photoshop\ \(Beta\)\ Settings (Mac)


C:\Users\user name\AppData\Roaming\Adobe\Adobe Photoshop (Beta)\Adobe Photoshop (Beta) Settings


Launch BETA Photoshop While Pressing The Keyboard Shortcut
With Photoshop closed, press and hold Shift+Ctrl+Alt (Win) / Shift+Command+Option (Mac) on your keyboard and then Launch Photoshop the way you normally would.

2. It may help if we could see your Photoshop beta System Info. Launch Photoshop beta, and select Help >System Info...and copy/paste the text in a reply.  

 

Thanks,

Hi Cory,

Many thanks for your response.
The issues were resolved following another update thankfully.
They were only occurring in the Beta app, but I updated later that day and it was fixed.

Kind regard,

James
