It's not a hardware related problem. WPF applications running under DWM update the screen at a lower rate than the DWM updates other stuff. This happens on high end hardware so obviously WPF apps are set to update at a lower rate. I want to know if I can change this setting as a developer.

You can see the effect easily when you use scroll bars. They lag behind the mouse cursor a little. If DWM is disabled they move as fast as the scroll bars in non-WPF applications. It doesn't look so bad actually, but I'd still like to be able to change this.
