P: MacBook Pro Apple M2 Max Laggy Liquify

How they can ignore problem with main functionality for cusromers ? 
Lets send them mamy emails whit the issues  , maybe someone can record podcast on youtube with the case to publicise this. 

Sameer K, No, that does not work for me. So this fault has persisted for nearly seven months now?

Mark Dahm, Thank you but here it is January 2024 and the problem outlined in this thread persists.

I am working in PS 2024/ Mac Pro 2019/ OS 14.2.1

@SergeiZ 

Update, the cursor method seemed to work for a while but it's back to 1.5-2second of click register and not moving in liquify again for the second liquify and on.

But the good news is that the warp tool glitched out graphics seem stable with the cursor method.

The problem is still there. My methods are a merely a work around it until the issue gets resolved. I do my liquify as the first step to avoid the lag as much as possible. 

@SergeiZ  you must've went deep diving into PS setup, I never thought this was the culprit and was only tinkering with GPU support. This worked for me, albeit now I'm getting incorrect brush stroke size compared to the cursor outline on the screen.

So, after Adobe rep said fix was out with patch, it did work for the first layer I worked in liquify but layers after or the same layer going back to liquify had terrible lag (pixels moving in liquify for about a second or so then stops). So creating a new layer hasn't worked for me since day one.

For some reason your cursor method worked for this particular issue and my other problem, of transforming selection and then going into warp getting me glitched graphics during drag, as well.

Here's one more step you can do to aliviate the problem.

Creating a fresh layer for liquify edit completely fixed the lag for me!!!

I have just a solution for iMac Pro with the latest version of Adobe Photoshop and Latest Mac OS version.

It has to do with the Cursor settings in photoshop.

here is what I did:

Go to Photoshop Settings, Cursors, Set to Full Size Brush Tip, Brush Tip Outile - Thin.

At the moment of this report, I was on Mac Os 14.2 ,

Last night, I updated to 14.2.1. The problem got a little better, with occasional lag here and there. 

Still buggy perofrance with liquify. I noticed that if i shrink the photo when i do liquify actions, the performance gets better. 

what OS version do you have? thought this was Apple silicon specific problem but if older intel macs with newer OS have the problem then this might be originating from OS.

I have lastest LRc, PS, and macOS installed on my M2 Pro mac mini at this point and still getting insane stutter (don't know if I should be calling this stutter cause my click/drag only regusters about 1-1.5seconds before not making changes on photo) after I admit the change and re-enter liquify later to do some more liquify.

This has been going on since they released stutter free version of PS.

really wish Apple would allow people to roll back macOS to their desired version, not limiting by the H/W release date.
