Tesselation Shader (DX11) - Standard assets

For some reason, Tessellation example that comes with Unity 4.0 isn’t working. Am I the only one with this problem?
I imported the package in the empty project, and opend the _TessellationScene.

Seems to work here… does your unity title bar have text ?

For all of you who have the same problem:

Edit->Project Settings->Player

Under settings for PC, Mac Linux, in Other Settings section you have to enable “Use Direct3D 11*”

Is Unity4 released already or what?
EDIT: Oh it is released, good news:)
