I am running PSCC 2018, just did an update a few days ago and using a Wacom Intuos tablet and also just updated it. I just started to mess with the pen tool and when I go to make a point and adjust the handle bars after the first two I get some major lag. When I use my mouse I may get a slight lag but nothing that really bothers me. I have tried different usb ports and even tried doing a reset using ctrl+alt+del when I start up PS. Any suggestions on what's going on or what can solve this issue?
Please look here, maybe you can find a solution or some hints:
At the end there is this suggestion:
"I have found that if you have Smoothing or Dual Brush enabled in the Brush Settings, you will get a great deal of lag when zoomed in. Once these options were disabled, my brush acted normally. "
