Brush stroke delay (Not lag) - brush stroke doesn't appear immediately - Windows

Hi,

 

On windows, when I start a brush stroke the stroke doesn't appear immediately. For example, if I hold still the pen on the screen it makes a mark only when I release the pen. If I make a stroke, it appears only when I'm few millimetres away from the starting point. That's very muddled but annoying, and it only happens in Photoshop. You can see it in the attached video.

 

I'm drawing on tablets and I have this issue with both of my tablets (Huion and Wacom), I'm on windows 11 and I tried on a Windows 10 too.

 

-> I'm up to date with Photoshop(23.1)

      -> But it happens on previous version too.

-> already tried to reset preferences

-> already tried to disable windows ink (In table settings, and with the user setting files)

 

Any help ?

Have you tried turning off Photoshop brush smoothing? Brush smoothing algorithm was introduced in 2018 and allows you to get a more polished look, but it can cause some delay too. Try tuning it down even to 0% as in the picture:

Hope this helps!

Thanks for the report @Pixium I'm not able to repro here on my Win10 machine with Cintiq.  Do you have the latest Wacom Drivers (6.3.45-1)?  Also try disable/enable Tip-Up Assist in the Wacom Tablet Properties > Options...  Also, does this happen with one particular brush or all of them; try General Brushes > Hard Round.

Thanks for your time floramc and chad.rolfs,


floramc, I did try this option, that's what I thought first. It occurs with all brushes, even with the simplest ones, and also with the Lasso Tool, stamp tools... That's not really "lag" cause the brush flow is nice, it's just a delay : the stroke appears just after I start moving my pen. Once the stroke has appeared, everything goes normally.

I have a very, very fast PC with high-end components, it can't be a lag, as all the other things run pretty well.

 

chad.rolfs, i work mainly on my Huion, but both my Wacom and Huion are up to date Drivers&Frimware. Did your brushstroke apear immediatly on your windows 10 ? Like, you pen touch the sreen whithout moving, and a stroke apear or you have to move or release the pen to see the stroke ?

 

This guy speak about this issue here at 6:39 : https://youtu.be/F3MlhIaK-y0?t=399

But his fix did not work for me "That's because windows ink use time delay to know if your make a touch or a swipe"


On fast and big brush strokes it's not a problem, but for tiny lines or handwriting it's quite annoying.

I just tried on a MacBook, and it does not occur. The stroke appears directly. I tried on 3 differents windows PC, and the delay occure on all of them. In fact this is a long term issue for me, that's why i finally decided to ask for help.


It looks like something about Photoshop and Windows OS more than a performance or brush setting issue. 😕


I suspect windows ink, but I turn it on/off without differences.

I made a more detailed answer below, but yes it happens with all brushes even simplest ones. And it also happens with the lasso tool, stamp tool, eraser, select tool, pen tool.

 

This guy speak about this issue here at 6:39 : https://youtu.be/F3MlhIaK-y0?t=399

He say : "That's because windows ink use time delay to know if you make a touch or a swipe"

 

But his fix did not work for me, windows ink active or inactivate the problem is the same.

 

For the record, I'm a very professional user of Photoshop for years, and I'm also informatics engineer. So I tried lots of basic manipulation to fix this. I started to notice this issue about 2 years ago.

Thanks @Pixium! After fine tuning things a bit more, I am able to repro with a custom brush and other Kyle Webster brushes.  I did notice that it does not occur on the computed brushes, i.e. the default General Brushes (Hard Round).  Which of the solutions did you try from BoroCG's video that didn't work?  Enable airbrush-style build-up effects or the PSUserConfig.txt (WinTab) one?

@Pixium It looks like Scattering may be the culprit.  Try unchecking that, if it is checked, in your Brush Settings and let me know what your results are. Thanks!

Thank you for your time @chad.rolfs , and you're right, it does not happen with default general brush ! I also tried to build a brush from it and the problem does not occur. But I occur with all brushes I tested from Kyle's Brushes and also on a few other brushback I downloaded. If I made a brush starting by one of those DL ones, the problem still occurs.  

 

Which of the solutions did you try from BoroCG's video that didn't work? Enable airbrush-style build-up effects or the PSUserConfig.txt (WinTab) one?

I tried the PSUserConfig.txt, and i miss the "Enable airbrush-style build-up effects" info (as English is not my mother tongue) So i just tried and it seems to work clean with it enabled. But I don't need/want this effect on all of my brushes.

 

Also, I tried to change the scattering but it does not make any change.

 

Do you notice this issue on the free-select tool, and shapes select tools ? Cause I did so. It's not a real problem for those tools, but it's interesting to mention.

 

So thanks a lot cause we have half a solution on it 🙂
