Photoshop CC 2020(21.2) : App literally became critically slow with frequent stuttering

My specs for the test :
CPU : Core i7 3610QM
GPU : Nvidia GT 640M
Drawing tablet : Huion H610 Pro
PC Model : Acer Aspire V3-771

Greetings Adobe. 

You really have plenty of optimizations problems with all the features and changes you apply to Photoshop, and this since you left Creative Suite 6. I don't know what's wrong with you. I say you should optimize Photoshop so that, at least painting performance stays smooth even on an Intel HD 4000 GPU with a 2nd gen Core-i5 CPU. Yes, those are less than 10 years old specs but strategically speaking, your developers should know why, it's the best way to manage how well you optimized your app or not. Seriously.
So if you don't make tests on a 10 year old or less than 10 year old machine, performance problems will remain. And it's just unprofessional to hide them just because y'all have GTX 1050 GPUs with last gen Intel Core CPUs. It's unprofessional to have your app slow down in performance when its newest features are not used at all. I'm talking about rendering fps and painting performance regarding speed of execution.

Anyway, I tested v21.1.2, v21.1.3 and just now v21.2... And I don't congratulate you at all.
Now Photoshop became slower and gives constant stuttering for its rendering performance. It's to the point that I can't even imagine using it anymore. 
Just how do you even optimize your code and algorithms ? 

I was curious today for something else as well. I tested Photoshop CS6 after installing it. And guess what ?
Photoshop CS6 was running butter smooth. And some of the problems caused by your newest features to the point that you broke your wintab implementation in latest versions of Photoshop, were absent ! I was using wintab and painting strokes was 4 to 5 times faster and smooth than in Photoshop CC 2020. Plus there were no stutter at all, and this was on a 5x7.5 inches canvas at 600 ppi resolution.
The reason I'm saying you broke your wintab implementation is because there's an exponential performance fault that is proportional to the time I spend painting any single stroke I'd hold for a long time(more than 20 seconds) without releasing my pen pressure on the canvas.

If performance was this good and smooth in Photoshop CS6, I see no reason for it to slow down or get broken in Photoshop CC 2020 or even Photoshop PhCC 2021. Adobe, It's obvious that your developers broke things in Photoshop to degrade its performance. New features is OK, but they should never impact negatively the previously known good performance of a software. Unfortunately, this is what I'm seeing right now.

Anyway, this was a test report. You will consider this issue if you care about the quality of Photoshop.

The latest update has pretty much done away with all performance issues for me. Everything is working perfectly for me now. Anyone else in the same boat?

Same here, worse even with the 2021 and now we can't even enable legacy compositing in performance prefs.

No it's way worse. Have reverted back to 21.0.3 - that's the last useable one for me.

Each update makes the app more and more unusable. The text tool is an absolute joke at this point - something so simple as a text tool should not be so laggy. Also forget adding any guides to a document - it jerks around so much its absurd. I am so fed up with every update making the app worse and worse just to do simple things. And no - my PC is not that old.

Text tool is almost unusable now due to the lag

The only workaround for me is to disable GPU Acceleration in Preferences > Performance > Uncheck 'Use Graphics Processor'

EDIT: I'll add that disabling G-Sync has no effect for me (Nvidia GTX 970)

What is the most recent version that runs well, so that I can roll back?

Horrible! Frustrating to work after this update .It takes ages to start and close any item . Badly lagging and slow .I am fed up. Please do something about this :(

So I was able to get a little more speed out of 2020. 
Clearly they broke the bridges between the program and the gpu. 

They need to update their manuls and settings for gpu, there is no longer an option for nvidia to just use the advanced setting.  I went in and painstakingly set each option and check the performance. Also, PS is the only adobe app that I had to manually add to the gpu program list. 

It did give me a boost in speed, 2018 flys and 2020 is now just MEH with little lag. 

Adobe clearly needs to rewrite their gpu handling. I'd share my settings but I'm sure every card is different, I would go in and set the app performance. 

Side note, I thought I wrote this here before, maybe it was one of the many other "adobe is low forums"

I hope instead of adding new features to the next version they just focus on fixing their busted software.

Hey Adam,

could you tell me what you mean by "add to the GPU program list"?
First time I hear about it and I am curious to try to get some performance improvements:)

Cheers,
Dziga

It's different for amd but for me on nvidia
Open up nvidia control panel>3d settings>manage 3d settings

Then go to the tap that says program settings, there is an add button. Click that and find photoshop and also sniffer. 
Then in the settings this is where you have to manually tell it what to do. 
Like in my OpenGL rendering GPU option i had to tell it to be my 1080ti card. 

I went through all of them and tested it, I'm probably not a 100% with it but it was better. 
Also in PS go to preferences> preformance > advanced setting in the us my gpu
I found openCL is crap and ani-alais guides and paths is also a pile of crap, i turned them off.  checked Use graphics processor to  accelerate computation and set it to advanced. 

That gave me a boost, 2020 is slow but better. 2018 is rocketing.

Adam, what is "Sniffer"?

30 Messages

I guess he refers to the "sniffer.exe" file in the folder at following path (Win10)
C:\Program Files\Adobe\Adobe Photoshop 2020

Though I have no idea how to implement his suggestions.

Besides, 2019 is working fine for me at the moment (and I guess I'll have to stick to this version for the next few years)

Yes that's it. 
They suggestion comes from an adobe site for nvidia setting that needs updating

Going to have to "me-too" this one. The last 3 updates or so have left Photoshop nearly unusable on many systems. It just seemingly locks up and becomes very unresponsive and hard to work with. It takes whole seconds to do even simple tasks like toggling layer visibility or moving a layer. I'm not joking, whole seconds!
I can't even figure out where the bottleneck is. It can only be some bug that will hopefully be fixed soon. We are at the mercy of Adobe.

Old Xeon 10-core, GeForce 1060 6GB with latest drivers, 64 GB RAM, program and cache on SSD.

PS2020 is unbearably slow, 1 frame per second at best just moving the image around.

PS2019 with the SAME document feels like a fresh summer breeze, easily 30+ fps.

This is NOT a hardware problem. Adobe messed that one up hard.

I too am seeing extremely laggy performance on multi-artboard PSDs, on my 5GHz i9-9900K, 128GB RAM, RTX 2060 PC... it should not be this slow!

if you're running Gsync, try disabling it and see if that fixes the lag.

Thanks – I'm not running GSync.

I've noticed lag on multi-artboards, and in particular when guides or transform boxes are shown – essentially when PS is drawing vectors. I've turned off "anti-alias guides" in the GPU settings to see if this was connected, but it is not.

I have also updated all my drivers and reset all my Nvidia profile settings.

I have been a user of Photoshop for many years - Best version for its time was Photoshop 7!! Now on Photoshop 2020 - absolutely terrible!!

Slow, erratic, crash prone - not what I am paying for. I'm trialling Affinity, perhaps I'll change after all these years. Adobe really must get its act together or lose many more long term customers.

I agree. I have quite a fast system, but many things in the latest upgrade are very slow to happen - stacking, blending, sharpening to name but a few.

I feel as computers get more powerful developers get lazy and release poorly optimized software just to rely on brute power to have them run. Cracks appear especially when you start to work with larger files 200mb+ (Not even that large 50layers 4k res 8bit files). I'm using a 40 core xeon workstation with 128gb ddr4 ram and photoshop still locks up frequently for 10+ seconds before releasing a burst of brush strokes and commands all at once that I was doing during the hangup. I just close and reopen and it'll give me about 15mins before it starts doing again. I'm surprised this is still industry standard, won't be for long at this rate.

@JasonWilliamson you might have a different problem. I've had a similar issue with a brand new Dell workstation in the last year. Plenty of RAM, but the whole system would freeze for a few seconds every 5 minutes or so. It was infuriating, but eventually I uninstalled some Dell bloatware and all was resolved. eg, https://www.dell.com/community/XPS-Desktops/XPS-8930-freezes-for-3-5-seconds/td-p/7346463/page/37

There's a major new version out now (22.0). Did this improve things for anyone? 

I'm stuck with 21.0.3, as the performance issues were too severe with anything later. I'm reluctant to try 22.0, as the changelog makes minimal mention of performance issues at all, and I got burned the last time I had to rollback when I had to redo all my settings, presets, hotkeys, etc which took hours. (rolling forward a version is easy, as that stuff gets migrated, but when you roll back, I found it all gets wiped).

There are some significant under the hood updates which should affect performance positively. I think it's worth trying a fresh new install, but be sure to not delete previous versions.

I'm trying 22.0 but it still have unacceptable lag issues with large files, and we can't even enable legacy compositing in performance prefs anymore. It makes my Mac Pro runs like a 486 PC. With 20.0.10 it keeps flying, doesn't matter how big the file is (even a 2GB file with +100 layers).

Hey, just passing by to add my frustrating experiences with 2020 PS.

I had to update from 2019 version since I formatted my pc and the older version I could find to download was 22.2.4

It is frustratingly slow close to 2019. And I have quite a beast of a PC. RTX 2080 Super, 32GB RAM, i7 7700k, etc

Its slow to use text, transform, even selecting layers is laggy. 

How bad photoshop has fallen :(

 

Now, this thread is rather old...

is everyone still having issues?

has anyone found a temporary fix?

Is the new (2021) version better in performance?

Or if anyone knows how can I have my CC2019 back, PLEASE let me know. It was working so well! Now im stuck with this mess and with projects to deliver!

@Paula Shin I have actually not had any noticeable issues recently since updating. It used to be working on certain multi-artboard documents would be cripplingly slow to work on, but that doesn't seem to be the case on the same files, for now.

@Paula Shin  To be clear, I guess you mean 21.2.4, not 22.2.4 

I still have access to 20.0.9 for some reason - I guess I'm lucky. If I lose access to this version, I'm screwed big-time. I've turned off all auto-updating and I guess I'll avoid any manual updating from now on.

I tried 22.0.1, but performance was still very bad.

21.2.4 is much worse though for me - it's simply unusable - like 20+ seconds just to pan a canvas. So I guess give 22.0.1 a try if you haven't already

20.0.9 runs like a dream, though of course is missing some recent features. 

I have a decent PC too: GTX 980ti, 64GB RAM, i7-9700k, everything on fast SSD drives.
