In case you didn't hear of this youtube video already, it would be my pleasure to show you this video of Marcel Pfister in which he used a green screen with an Oculus Rift.
You must know am I a very big supporter of VR in racing/driving games. I think that this technology will revolutionise racing games as we know it today. I do own an OR DK2 unit and I can safely say that, at least in my opinion, there is no going back. Once you have experienced VR and looked around as Marcel does in this video, you are basically transported to whichever open world or circuit and get to sit in any number of (race) cars you have. The immersion level of VR is absolutely breathtaking and there is no comparison to triples or projection, mainly because of the fact that you are literally thrown in the game itself. There just isn’t anything else that compares to what is attacking your senses just by driving in VR.
Enjoy the video!
