wpf and graphics speed.

I am using a graphics intensive program in wpf and C#

Some of the screens can have a lot of graphics and this can become slow even on a top of the range PC.

Is there any way to speed the graphics up ?

I know in C++ you can use doublebuffered = true; and this makes a big difference.

It seems to have been in wpf but has since been removed as an option.
