Why does VR preview with the Oculus Rift not work anymore?
I recently tried to preview my project using the Oculus Rift DK2, but the VR Preview button was grayed out using the 0.6 Oculus runtime running in extended mode. I upgraded to the 0.8 runtime and it fixed the button being grayed out but every time I VR Preview it crashes. I also tried the 0.7 runtime with the same results.
Here is the crash report:

All works fine for me.
Windows 7 x64
GeForce 750 Ti
NVIDIA drivers 358.78 (this is latest GameWorks driver with VR support and recommended for work with Oculus)
Oculus SDK 0.8.0.0
I played Showdown VR demo in "VR Preview" mode.
