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.

I think that Photoshop now needs a hell of a lot of power to run it. I Thought my system would have handled it. I had an Intel  i7 3rd generation processor and 16GB of RAM, running Windows 7, but recently found that as well as the usual slow stacking, blending layers, and sharpening, the latest features such as the new sky replacement tool and the cut out tool for hair and such didn't even install. The message said that my system wasn't up to it. I have since - over the last week or two built a new system with Intel i7 10th generation and 32GB of RAM, running Windows 10 PRO. Everything now loads and flies through all procedures. Maybe that's the problem. It needs so much to run it. Anything not just upto it either runs slowly, or in my case not at all.

@Benjisdad I suspect that your previous system's graphics card might have been the problem

Hi DGrainger, thanks for your input. I thought the same as you initially, so I bought a Palit GeForce 1050Ti KalmX 4GB graphics card to go into my old system, but unfortunately it made no difference.  in-fact I had it installed before the latest update that said my system was not upto running certain features. The new system I built did not have any graphics ability built into the CPU, so I have used the same graphics card, and as I say everything loads fine and it performs all tasks quickly.

@Benjisdad I think you'll find Windows 10 is the minimum requirement you were missing. Windows 7 is no longer a supported platform.

You're probably right Anthony. My old system was Windows 7. I liked that old system very much, but needs must, as they say :-)

Lucky you, the new hardware solved your problems.

I continuously struggle with PS on i9 and Ryzen 9 5950x machines, which are pretty much maxed out otherwise (128 GB RAM, Gen4 M.2).

Only with the GPU I usually don't overdo it (and use e.g. RTX 3070 right now - much more silent and efficient than using something faster for PS IMO).

Photoshop & Lightroom have driven me crazy over the last month or so because they were so slow. I have scoured this site and others for fixes, which have helped - but not much. Today I ran CCleaner, and chose the Registry cleaner, which deletes orphan entries. Bingo!  whatever was slowing PS down was deleted.  It is still not as quick as the old stand alone versions, as described by the OP, but this has been a work around for me.

Unfortunately I have to queue into the many unsatisfied PS-users. And unfortunately I have performance issues even with extremely new and fast hardware (i9 and Ryzen 9 5950x, 128 GB RAM, Gen4 M.2, etc.).

I work on 16-bit images of 50 MPix and up and many layers, often with one or two smart-objects, non-nested though (psb-file size is between 1.5 to 8GB or so).

Well, I lied to you.

I don't work. I TRY to work.

With the last updates it has become increasingly impossible to use PS in a fast and productive way. Even on maxed out systems I run into performance issues and GUI problems.

BTW, this happens on totally different hardware.

I give PS workshops; my customers often use their own laptops (some very fast, some not so). Of course during those workshops I use 8-bit low-res images. But still it's so frustrating to see so many issues with current PS version: It's just not snappy & responsive as it used to be. Even VERY SIMPLE tasks (like dublicating adjustment layers) sometimes takes ABSURDLY long.

As some others have mentioned here already:

  • IMO Adobe source code seems to be a mess.
  • IMO Adobe has invested in shiny new features to lure more and more new customers into it's cloud paying model.
  • IMO Adobe has totally dumped quality control (and uses us CC-users as beta-testers with bug-plaged 'updates' all the time...)
  • IMO Adobe doesn't seem to care about modernizing CORE components (like performance of healing tools etc.) at all any more.

It's so absurd: Old PS versions on old hardware run MUCH smoother on 16-bit files than the current PS version with 8-bit files!... PS code-optimization is just non-existent.

IMO the gravity of the desaster is somewhat "hidden", because most customers probably

  • don't have tooooo complex psd-files
  • don't need ultimate responsiveness when it comes to pro-retouching (e.g. when you sample clone/healing/brush source points very fast)
  • don't use many advanced options which are especially dependent on good modern code optimization (e.g. nested smart filters incl. e.g. surface blur)
  • don't use 16-bit by default
  • but still have relatively fast machines. With this combination PS works okay in most circumstances. That is, apart from the horrible bugs introduced with almost all last 'updates' [which actally were "shiny-new-features-beta-versions", no optimized & well-tested final versions...].

Remember, that's "only 2D" = way way way less performance-hungry than e.g. complex 3Dim-raytracing/4K-gaming/etc. If PS core source code would be modern and optimized (and applying clever state-of-the-art graphics caching), it would run butter smooth on 10 year old hardware. And 100,000% snappy and responsive.

Empirical proof: Look at the competition. Not as many features (yet) => therefore  not regarded as "industry standard" (yet). But modern and fast source code. @Adobe: Take note of the little word "yet"....

    I have invested so many years of my life in mastering PS...

    ... therefore I personally would really hate it, if Adobe will become the Kodak of photo software in the medium/longterm future. But this seems inevitable to me, if nothing changes on Adobe's side, I'm afraid.

    @Flo I feel your pain. I recently updated my rig with a 30-series Nvidia RTX card. My workstation is now considered UFO-level for workstation capability by User Benchmark. https://www.userbenchmark.com/Faq/What-are-the-UBM-performance-classifications/93. But, the upgrade has resulted in significantly reduced Photoshop performance, because I upgraded PS at the same time.

    It's hard to imagine what state Adobe are in as an organisation when SSD and GPU advances are massively increasing PC capabilities - but their product continues to degrade in performance with every "update".

    Like so many, I feel like I'm on a sinking ship that we'll all have to abandon in the very near future. Adobe may be a big part of my comfort zone, but the productivity losses and the wasting of capable hardware, will soon make the retraining and workflow migration cost-effective.

    Jesus, that DGrainger is some serious shill. For months he keeps yammering about how really powerful computers, on which any other (up-to-date!) program works perfectly fine with no slowdowns from one version to another are at fault for the slowness of the last couple of Photoshop updates and there's no way that there's a problem with Photoshop.
    Imagine being so deranged to actually believe that. It's impossible. This is nothing but bootlicking Adobe for no discernible reason.
