Game loading in Oculus Rift Mode?

Sorry if this has already been posted - I did a search and nothing came up.  I just downloaded the demo, and all that loaded was a black screen.  After a few tries I thought, "hmm, maybe it is going through the rift."  Sure as heck, it was!  The problem is, I don't think it is set up to be played that way as it is all unaligned.  Short of unplugging my rift, is there a way to get it to just play without sending the signal to the rift?

Thanks for your help!
