Help! Shaky Lines In Photoshop When Drawing With Tablet? - photoshop drawing tablet

I bought a Wacom Bamboo Fun tablet, "a year ago, and when I create in Photoshop with the lines are very unstable ... If I rely on other applications, I do not think OT has a problem (I prefer to use the Facebook graffiti, but can not save while drawing ;__;)

My question is: Is there a way to resolve the lines of weakness in Photoshop? Is there a setting I change?

Any help would be very grateful ...

PS: I am not shake it: PI sure to do the team.
