Oculus Rift player settings - "Stereoscopic Rendering" vs "Virtual Reality Supported"

What’s the difference between the player settings “Stereoscopic Rendering” and “Virtual Reality Supported?”

I read somewhere (can’t find the link) that these are mutually exclusive settings. Is that correct?

Which should I be using for the Rift?

Thanks!

You should be using the Virtual Reality Supported setting for the Rift.
