Valve on VR Latency

A lengthy post on the Valve Blog written by software engineer Michael Abrash discusses his work on creating a viable virtual reality headset for gaming. He goes into detail on the issues involved in reducing the latency in such devices to practical levels, saying: "If you ever thought that AR/VR was just a simple matter of showing an image on the inside of glasses or goggles, I hope that by this point in the blog it’s become clear just how complex and subtle it is to present convincing virtual images..." He discusses some of the breakthroughs they have made so far, but admits "we've only scratched the surface," saying they are now in need of "a true Kobayashi Maru moment" to break through the final physical barriers preventing practical VR.
