Thank you for the response, Andrej. I downloaded and built your samples. It was on a rather old laptop so GPU performance isn't that great. The 3D performance gains were quite impressive, though. Other tests (like the VisualBrush) shows little perceivable difference from the standard WPF rendering engine.

What I really need to do is some testing specifically with my app. Hopefully I'll be able to do this soon.
