Unity crashes with Oculus Rift

I created an empty project in Unity 5.1p1 including only standard assets characters.
Usig Gamma lighting, Forward rendering, no antialiasing.
Checked Virtuel Reality support (stereoscopic rendering is unchecked).

Oculus rift is on extended mode. Running demo oculus rift apps works.

Game view is set on maximize on play.
Whenever I press play Unity crashes.
If I build an application and run it, it crashes as well.

I've tried it in several of my projects as well as in mentioned empty object....
