I have a Wacom Intros Pro to use with Lightroom and Photoshop CC. It works perfectly until I was trying to slide the exposure slider, it is so sluggish. Then I tried other sliding bars, the same happened, some are worse than others. It is impossible to move them precisely. At the beginning I thought maybe it was my Wacom, then I opened Photoshop CC with Camera Raw filter. It works perfectly. So, it must be a Lightroom issue. I did a quick search and see a lot of people using Wacom having the same issue. Please help.
I am working on a iMac 27 inch 5k display with 32gb ram, Lightroom CC and Photoshop CC updated to the latest. Thank you.
Thank you for the quick response.
I have tried to tick the box on and off, I can feel it definitely had some improvement, but still far from acceptable. With use graphics processor on, the lag is about 3 to 5 seconds, and with it off, the lag is about 1 or 2 seconds.
Hopefully there will be an update in the near future to fix the problem.
