This conversation has been merged. Please reference the main conversation: Lightroom: Laggy sliders on Windows with Wacom tablets
Windows 10 Business Edition 10.0.16299
Lightroom Classic 7.2 
Wacom Driver 6.3.29-4
These are the latest versions as far as I know.
When the "use Windows Ink" box is checked there is slider lag where the slider does not respond to initial movements from the pen. Also the adjustment brush does not begin to work as soon as the tool is applied. It also has lag.
When the "use windows box" is unchecked, there is no slider lag but the pressure sensitivity is then lost.
I tried disabling some of the windows pen features as per this somewhat crude blog http://i.imgur.com/Viuhhok.jpg
but it did not make a difference.
I've also turned off "Use graphics process - that did not make a difference either.
If you have any other ideas please let me know.
Wacom says leave the box checked and get Adobe to fix their bug. Adobe support said "the adjustment brush in Lightroom isn't pressure sensitive so whats the problem?"
Note: This conversation was created from a reply on: Lightroom Classic: How about making the Lightroom Brush pressure sensitive.
