Photoshop Tools Are Very Slow

[canyonlight]

Lightroom Version Number

Lightroom Classic 10.0

Operating System

1. macOS 10.15 Catalina

Running Photoshop 22.0.1 on a 2019 Mac Pro (macOS 10.15.7 Catalina) with plenty of RAM, scratch disk space, etc.

Some Photoshop tools are very slow.

For example, Lasso Tool used to draw small space to add to current selection takes approx 5 seconds to add selection. First selection goes okay, but additional selections lag badly.

Same results with brush tool in Content Aware Fill preview when attempting to brush to add or delete content source pixels.

Would appreciate any suggestions.

Gosh. This one generated a massive response.

Can't respond with much insight.
First I am on a pc, not a Mac.
Second, I am running the latest PS, and I don't see these slowdowns.

On a pc, I can check the resources (cpu, ram, GPU, etc) and how they are being used.
Do you have the same on a Mac and try to see where the bottleneck is?

Thank you Jim. I can try your suggestion.
I am also on Adobe forums, and many folks seem to be having this problem.

I have found the answer to this problem.

I have Tony Kuyper's luminance mask action panels installed on my Mac computers.

I just received an email from Tony today with some troubleshooting instructions that included the following for Mac computers:

"...The second Mac problem concerns sluggish performance of some tools, like the Brush and Quick Selection tools, when TK7 modules are open. Again, I've not been able to reproduce this, but have four reports of it. The solution that worked in all these cases is to simply turn off the selection indicator. To do that:
1) Click the "TK" icon on each module.
2) Choose "Off" in the Selection Indicator drop-down menu...."

This solution cleared up the sluggish tool problem.

This solution cleared up the sluggish tool problem.

Glad you (someone) were able to find it.
The more complicated that software gets, the harder it is to test all possible configurations for issues and problems.
