Xbox One 8% performance is being rumoured thanks to removal of the requirement to hold 10% of the system resources for Kinect. In future developers will only have to reserve 2% for the microphone but the 8% for video will be free for use by gaming, however the developer wants to use it.

I said it right at the start of this generation that Kinect is the albatross around which the Xbox One will fail..Now do you believe me? Even Microsoft has lost confidence!
