Is there a way to have the oculus rift running but then on the monitor have the image be full screen without the oculus rift look. It would work in the rift but people standing around can see what is going on but the monitor would look just like the game?
+1 for something like this.
I guess adding an extra camera / screen will impact performance pretty bad but there are lots of use cases that the performance penalty will probably not be a problem.
You would have to render to multiple render targets and windows at once and output one camera view before applying distortion. Possibly but no support “out of the box” 
And yes it would cost you in perf.
