Mac OS Wacom brush lag
UPDATE: I kept researching and found on another support blog to try hiding the rulers and right away my brush quit lagging by at least 85-90% improvement. Actions taken: View > Rulers > Hide Rulers. Weird, but it worked for me. I hope this helps anyone else with this issue. Ideally, we'd like to have this fixed so that rules can stay open, but nice to have a quick fix too.
I'm on a MacOS Catalina (most recent Mac upgrade). I'm using a Wacom Tablet (up-to-date drivers) and the subscription version of Adobe Illustrator. My brush is lagging so badly that it's impossible to draw correctly and in real-time. This is only happening in Adobe Illustrator and it is up-to-date. I've tested Adobe Photoshop using my Wacom Pen and brush tool and it works fine. So I've definitely ruled out that it's my Wacom driver and/or pen.
I should add that before I updated my Mac I was using the CS6 box version. But after updating my Mac I was forced to purchase the subscription based programs because this killed the CS6 boxed version. Prior to all of this, my brushes/pen tool was working smoothing and not lagging. In other words, never had this problem before. I've tried looking through troubleshooting ideas and nothing is working. Please advise, this is my work tool and I need my brush and pen to work properly.
