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 :-)

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.
