title: Can DirectX cause WPF applications to render very slowly?
body: <p>Suppose I have a DirectX game running in full screen and a WPF application running in the background; in addition, the CPU isn't at high levels, and the game's frame rate is good (i.e., 60 FPS).
  Is there anything that might cause the WPF application to render itself slowly? (i.e., at 3-5 FPS)</p>
