Huge amount of drawing lag

I can’t get past a single pen stroke. I’m using a Wacom Cintiq and there is an insane amount of lag between drawing the line and the line appearing, if it ever does. In Photoshop it works fine, but I just can’t seem to get it to work for me in Toon boom. Any help?

Try going into the preferences and on the “Advanced” tab, reducing the “Delay before vectorizing strokes”
Also try updating your graphic card driver if possible.

If neither solution makes much of a difference, it may be due to the tablet driver.
Removing the old one and installing the latest one may help but try this last.
