Cintiq 24 pro utilizing high CPU with brush strokes

Postby gasknr » Fri 6. Sep 2019, 02:04

I have had a problem with my Cintiq Pro using unusually high CPU usage and I cant figure out why, its been going on for a while and its costing me money because it causes my brush to lag constantly and my productivity is heavily reduced, not to mention the downtime trying to figure out why.

My testing shows that during any continuous or overlapping brush stroke on my cintiq my CPU will go upto between 32-41% usage, no matter what the brush settings..
On my intuos, running the same test my CPU usage will rise to 3-7% ????

At this stage my cintiq sits off, or when I do use it its just to stream netflix whilst I work. no ideal...

- My drivers are upto date
- It is NOT MY SYSTEM, I have a powerful machine.
- It only occurs on my cintiq, I work on my intuos pro, same files, same settings, same everything and there is no signs of lag.
- I have tried both windows ink off and on
- I have tried changing the resolution of my cintiq, reducing down from 4K
- I have tried both 8/16 bit files, same scenario.

Can anybody help me?

First make sure Windows and the the Graphics card driver are up to date.

The way you describe the issue, this can only be from the computer and / or the software you are using. I am not sure which software you are using but please check if there are any recommended settings from the software developer.

I dont see how this can be an issue with my computer when I can only recreate the problem on the Wacom Cintiq. So on the same computer, same file with same software and settings, I can work on my intuos 5 going to my Eizo screen and everything is perfectly fine. I drag over Photoshop onto my Cintiq, in the exact same work session and I get the problem, brush strokes in Photoshop are very laggy and have a hard time keeping up, pushing my CPU to around 40% usage. I have tried every different setting I can change within the software and on windows and I cant see anything different, still a problem

I know brush lag is a problem in Photoshop with recent versions but the fact that I can only recreate the issue on my Cintiq points to a what I suspect a driver issue, drivers have always been hit and miss with Wacom and I am basically at a loss with it all. I feel like I have a $3000 24" television at this point, I am back to only using my intuos exclusively ..

My system is upto date, its the first thing I check when I encounter issues.

Are you using Windows Ink?
If you disabled it for your Intuos you will need to do it again for the Cintiq settings.

This indicates that the computer is struggling with rendering the strokes. The driver is not doing any processing or calculation on the strokes. The Wacom driver is only processing the data from the tablet and feeding this data to the Operating System through Windows Ink, or Wintab. If this was a driver issue, you would have the same problem with the Intuos 5 which is not the case.
