Illustrator :: How To Achieve Less Smoothing With Brush Strokes And Wacom

Is there a smoothing setting for brushes? When I draw certain shapes with sharper corners (like squares) illustrator rounds them out very excessively. I know there has to be a certain amount of smoothing to convert a stroke made by the user into a vector, but is there a way to reduce the amount. Interestingly, if I draw the shape really fast, I get the desired result, however if I draw slowly, it rounds it tremendously. I would think it would be the other way around because with a slower stroke you are giving more input points and therefore more precision but this is obviously not the case. Basically, I want to achieve brush strokes that more accurately represent my input. T
