P: Sampling lag and stutter with either clone stamp or healing brush

@Christian Schranner  
I have GPU recognized properly in Photoshop,..... in Device Manager only that GPU (GTX 1070), nothing else....and still laggy. 

So after more than a half of the year Adobe leaves that horrible bug unsolved! 
 

@mihaiudrn I checked "Auto Hide" in the "Clone Source" panel and, at least when I brush, it's a little bit more responsive (because it hides the source temporarily).

But yes, it's still laggy.

I have the rtx 2060 super oc and the stutter is still there, almost 6 months later, working on 8000+ pixel images with few to many layers. Nothing that i tried till now really worked, except for unchecking show overlay, which i don't consider being a solution. 

Also it's even more laggy if you zoom in past 100% in the image. 

Yes, I only have one card listed (it's a 1070ti, drivers updated).

I usually work with tiff files, I doubt the filetype is the culprit but I might give it a shot.

Also, what settings are you working with? "current and below", "all layers", "current layer"?

How many layers do you have in your document?

My apologies for so many question, I'm just eager to find out what's the problem..

Many thanks

Do you only have one graphic-card listed in device manager? hmm..
I work with raw and psd files since over 2 hours without any problems. my files are over 8000px lenght

Can you please try it with large documents, like 6000px or more? Because I don't have that option in device manager and with large documents the problem is there.

Thank you

GUYS, i solved the problem:
- In Windows, go to "Device Manager", disable internal graphic-driver. 
- Start newest Photoshop version, go to "Edit" - "Preferences" - "Performance" and check if Graphic-processor is used.

I found this video:

So, my issue with laggy clone tool is now solved! YEAH! Thanks so Adobe

ugh, sorry my comment didn't pan out.

guess it's up to Adobe, whether they intend to or by happy accident,

to somehow fix the internal code for you.

my saying so may not mean not much to you, but, best of lucks to you on finding the solution

Hello,

Thanks for your reply. My windows scaling is set to 100%. That does not seem to be the root of my probles. Been so long since i started this thread that i've given up. After so much wasted time thinking i finnaly found a solution, nothing actually really worked, it goes back to it's stutter while pressing alt, especially when I am zoomed in high resolution images.

it's been two months sine last input but I gotta ask,

What's your windows magnification in display setting?

I usually have my Windows at 150% or 175% and

photoshop clone tool is laggy with "ruler" on

after setting the windows magnification back to 100% it's back to business as usual

I've gone through several days, turned into a few weeks, to figure this out

and later was able to come to my conclusion with help of this blog

the result video I recorded may not be obvious but it's million ways better than the stutter.
