We know that there's a new Rift prototype to be unveiled at CES 2014 in just a few weeks, with the new VR headset having a reduced latency of between 10-20ms, down from the original developer kit, which has a latency of 60-70ms.
Better yet, is that Oculus CEO, Brendan Iribe, spoke with VentureBeat, where he talked about the latency: "When you put it on - the latest internal prototype, which is what Marc Andreessen and his team saw - it's a completely different experience from the previous versions. The latest one finally ties it all together. There's this switch in your head. Your brain, instead of feeling like you're looking through a VR headset, suddenly feels like you're just looking through a pair of glasses into another reality. It's much more comfortable."
He added: "We got our developer kits - the prototype that you saw way back when, at the last CES - running at about 60 to 70 milliseconds. Our most recent internal prototype is now between 10 and 20 milliseconds. Less than 20 [milliseconds] flips the switch and you cross that threshold where the brain feels comfortable with it. You're not reminded you're looking at a computer device."
