P: Photoshop 23.3 is slow and heavy

Same issues here. For example, for a treouch I'm doing on some images now, I create a new blank layer, then hit "V" (move tool), then "3" to set opacity to 30%, then "B" to switch to the move tool. after hitting the B key I have to wait several seconds before the tool switches. Or if I need to use the hand tool to reposition or +/- to zoom, I have to wait several seconds for Photoshop to catch up. Previous version (which I just re-instaled) I can go from step step all teh way through with no delays. Very bad when you're editing 60+ images.

There is a delay like the video attached by the writer.

Don't know how many times I reinstalled everything. This is killing me.

When Zoom over 50%, you can see delay
PS2022 test (problem current version)

PS2020 test (stable version 21.0.3)

PS2015.5 test

all scenarios <<< (Except for one thing when image is small, like lone edge pixel 1200?)

(but that's really small file, Basically, the pictures taken are over 3000px =( )

And i'm talking about the current version(23.3). 
The reason why I mentioned a specific version(shch as ps21.0.3 is no liquify lag, ps2015.5 is no lag when layer toggle) as an example is to inform you of a stable version that does not cause delays or problems.

I think the layer toggle delay bug that occurred after ps2015.5 was caused by the change of engine inside Photoshop, and I also know that it is not easy to solve it.

BUT, must fix that Liquify zoom lag...

I like the specifications of the computer, so there is only a short delay, but most people say that when zoom in more than 50%, there is a delay of at least 3 to 5 seconds.... isn't normal.

And i think it's not just delay. I felt like needed time to load the liquify once I ran it.
So, What I suggest is this. Something seems to be wrong with the code that loads the image when you run LiquiPi. I think it's better to focus on this part and fix the bug.

It's the same when there's only one layer, not dozens of layers. That's what happens with all the files of a typical size, and it's not just me, it's the people I know, and it's going through a lot of people in communities like Reddit.

Sorry to hear about the troubles.

- Is this happening on a particular file or in all scenarios?

- Is this a comparison between two recent Photoshop versions, or a comparison of Photoshop 2015 against new versions?

If you have any sample files that you can share, that would be helpful in diagnosing the issues. Also, please share with us your system info (launch Photoshop, and select Help >System Info, then copy/paste the text in a reply). This in turn helps the team prioritize what type of performance improvements to work on as well as determine if there is specific hardware that is struggling.
