Photoshop 2020 (21.1.2) - Wintab and Windows Ink actual issues

Greetings to Photoshop's Engineers.
I have unfortunately noticed issues I would consider critical to the app's performance. It's Photoshop's implementation with the old Wintab API. I want to inform you that brush performance performs slower and slower over time the longer you hold any single stroke and it really is shame to have the software performs this way. You may try in the most brief delay to fix this issue so that Wintab performance matches that of Windows Ink if not better.

With WIndows Ink, there are also issues :
As you stroke with your brush, still without lifting your hold, pressing Shift key immediately disable pen pressure and as soon as you release the key, it gets back.

There are tons of frustrating milliseconds delays in most click actions, including holding Alt+click with a pen and windows Ink active. 

With layers, it's difficult to open/close a layer group by clicking on its icon in the layer panel. Unless you click once in a tricky way, or quickly multiple times, the action doesn't perform and briefly show an "action block/invalid operation/crossed out circle".

All these were test results on a PC with the following specs :
intel core i7 3rd gen CPU
Nvidia GT 640M GPU
WIndows 10 1909
Drawing tablet : Huion H610 Pro with latest available driver(v14.8.90.1126)

That video circuit is a laptop one dated in 2012. You also do not mention how much system RAM is in the laptop.  I think that you at the least should update drivers directly from Nvidia and not by using the Windows System Device  Driver-update in control panel. You apparently have a computer that is older and you might want to update it> That 2012 laptop probably started out with Windows 7 and was "upgraded"  to Windows 10 during Microsoft's big push a couple of years ago; therefore you may have other incompatibilities with older hardware as well.

Possible. But buying a modern laptop with a decent GPU costs a freaking lots of money.
And I'm still powerless to buy, say just the bare-minimum. By bare-minimum, I mean a laptop built in 2018 with specs like a core i7 cpu, and GTX 1050 GPU.
Also, I understand that RAM is needed to allow programs to perform operations. But raw performance itself, regarding data computation, is handled by the components called either CPU or GPU. So this is where speed matters the most. Not the RAM. 
If RAM was an issue, we would mostly experience big latency, but after the latency delay ends, you experience during the catchup the expected performance speed. 
Lack of RAMs = repetitive latencies/delays before most operations are handled/performed or no execution at all due to lack of RAM memory.
Lack of computing power = operation performs but at a very very lower number of frames per second.

Do you know how to code ? If you do, you will understand what I mean. Because usually, to prevent buffer overload and having your program stuck on a task, the algorithm behind an operation must check whether there's enough free memory in RAM or not. In the latter case, you use an exception and prevent the operation to perform...

So I may agree with you aboutt some hardware incompatibilities. But honestly, they are minor. Else many many things wouldn't work.

Lack of sufficient RAM will degrade performance because both Windows and any program that you are running will swap out to hard disk when there is not enough RAM. That is why I asked you how much RAM is in your system.  Virtual memory is very slow compared to RAM. Space in memory, meaning enough memory to contain things upon which one is working and program components, must be large enough else swap to disk is done.

There have been quite a few posts in this forum wherein it has been explained that older hardware, specifically GPUs that are out dated, affect Photoshop FAR more than other software. That would be the reason that your other programs do not seem affected, but PS is.

There is a tendency to wish away a solution when there are budget constraints; we have all been there at one time or another!

Ed, are you still having trouble with the 21.1.3 update that went out yesterday?

Yes ! Issue persists. Here, look. I recorded performance comparisons between Wintab and Windows Ink.

Windows Ink next.

I'm now setting up a brand new wacom intuos pro medium. Should I install the latest driver from wacom's site considering I'm using photoshop 21.1.3?

One would think!
