P: Photoshop 23.3 is slow and heavy

@greg-ory  Various lags in Photoshop have come with various updates.
Acutally, There were many changes in the comfort of the work when it changed from CS version to CC version, but it was not that bad. And as time went by, the computer specifications of Adobe customers got better.
And the 2015.5 version of Photoshop is actually the last time we were able to photoshop comfortably.

Until 2018 version was okay.
However, since the introduction of a new development composite engine in 2019, everything began to be delayed from the canvas inside Photoshop. Of course, it wasn't a big delay from the beginning. But for those who have been using Photoshop for a long time, it's an intrusive delay.

And many problem was start.....(Zoom lag, Select and Mask freeze, Cursor too thin, over 30+layer in16bit incredibly slow... etc)

In fact, the bug above has not been fixed yet.

For example, the thread of the link was also uploaded by me, and that problem was a problem that many people have experienced since the 2017 version of Photoshop, and it was fixed not long ago. lol

Most of the 2020 versions of Photoshop were stable.(It's not as pleasant, light, and accurate as it was in the past, but there were still a lot of delays.)

But... Since 2021 again, the interval between delays has been shortened, and the feeling of delays themselves has become very heavy again.

So, What I want to say is this. It is true that there is an improvement in speed with the introduction of multi-threads and GPU composite. However, If the original speed was a sports car, now it's walking speed.

This is not a matter of computer specifications, nor is it a matter of system OS differences. Hundreds of computers and hundreds of team members shared information.

It's a problem that comes from Photoshop engine processing, so it's not something that can be solved simply by something like native canvas on/off or gp turn on/off thing.(Btw, In fact, it is also strange that some options should be turned off to improve the problem.)

Anyway... I hope it gets fixed soon...

Well, curiously, it's the first version that fixes every heavy lags I had since photoshop CC ( not sure which version but it was years ago ) thanks to this new multithreading mode ( way too underrated and hided )
I can't believe we got this just now

@Andrew Sender thanks for report. I hope it improves as soon as possible. Thank you.

Hi @Jqqerry ,

Thank you for trying those different prefernces.  I have filed an internal report with our engineers.  There are a number of customers reporting similar issues.  So we are definitely looking into this with priority.

Same problem .

Select and Mask Crash everyday, and if not that happen...

use Refine Brush.. loading or freeze or Werid Square or bluurry select.

I know what i have to do, and use way. i'm retoucher for 15years.

To be really honest. Does this function work? 

I haven't been able to use this function properly since 2015. Every time there's an error and it's slow... (It's not my device problem. Because i test many type of OS, Computer spec) Window/Mac, intel/amd, nvidia, radeon.. 

Yes. I work manually select all the time. brush or Channel, Calculation, luminosity things.....

BUT, Why should I do that? I want to use some functions that I have............ =(

My main device is win10 Ryzen5600x Ram128GB 2070super, and M1 imac. 

All the computers I use as my main focus also have such delays or bugs.

⬇⬇⬇⬇⬇The contents below are what I did.⬇⬇⬇⬇⬇

Reset prefs. Reinstall, No use Plugin thing. Reinstall OS, Try current GPU driver,
And old driver is same. Change HDD , SSD , Nvm2,
Deactive canvas thing, Multi thread thing, GPU comp thing.. I've tried all of thing what i can way.

I'll ask you one last time. I'm not angry. I'm really curious.

To be really honest. Does this function work? 

And photoshop 2015.5 is a really good environment and an example of an update, but 2018 (19.1.6) is also a good example if you can't go back to that pace.
Version that can be the basis for updates : ps21.0.3 or 19.1.6

Do you know why I suggest a specific version?

Because I installed and tested all the versions I could, all the builds, and I found some versions that were not restricted in actual use and had no bugs.

This is not a limited version of liquify zoom.

The Two version(ps21.0.3 or 19.1.6) is very stable and faster than Compared to all the versions up to now(23.3.1)

liquify zoom lag bug, layer toggle visibility lag, zoom and hand tool lag, Just all the thing delay slow in 16bit workflow, also If there are more than 20 layers, it's lagging

There are many differences even in a typical environment that is not heavy. Based on my suggestion, please improve the working environment compared to the previous code.

thanks and plz help us.

image depth 16bit. And size is mostly 4000~7000px. 

window10 / ryzen5600x /  ram128gb /  gpu 2070super / 1tb ssd for Scratch disk

Most work in 15 to 20 layers. (Sometimes more is needed. Because I have to leave the process to edit it at any time when client requests a change something)

But I don't know when. It doesn't apply heavy filters to cpu or graphic cards, but simply using hand tools on the canvas to move the screen, or even small-sized brushes or clone stamping (from when there are more than 5 layers)

(There are times when the delay goes from 0.5 seconds to 10 seconds. If I have to wait 10 seconds for every task, how much more time do I have to spend working on my entire picture? If you actually have 20 minutes to work on, I think that's also 20 minutes if you add up the remaining 10 seconds of delay.)

Okay. I and you know about this. 16bit workflow need more ram, more hdd or ssd storage becausre really hard work.

But Until a few years ago, there was no delay in my work even if there were more than 50 layers instead of 5layer. =(

These are the ones I've tried.

1. reset all setting prefs, reinstall photoshop

2. reinstall windows manytimes

3. reinstall other gpu driver

4. test other device(shch as intel cpu setup, mac mini , mac pro, imac)

5. no plug in, no extension

6. dont need our log. because System logs are meaningless because they have been newly installed and tested on various types of computers.

Everything had the same result. It's slow. Specifications are good enough and there's no reason to be slow. Because it wasn't slow before. Then this isn't my fault. Something went wrong with Photoshop being updated.

My job is to use Photoshop, and I pay Adobe every month to use Photoshop, a means accordingly. Adobe offers many functions and conveniences and feels grateful for them. But most Retoucher like me don't need that kind of convenience. Rather, we need to improve our working environment. It's not exactly an improvement, it's a return to its original speed.

I want to get a reasonable result on what I paid. Thank you.

Same issue on here. "must fix liquify zoom laggy"
When I first experienced this phenomenon, I thought my computer was broken. So I even bought a new computer! lol 
I wasn't satisfied with Adobe's monthly subscription service, so I spent a 2000$ to get a better computer, but the results were the same.

Please, can you work overtime to fix it, or go back to the previous version, can't stand it, ！！！！！！！！！！！
