Throwing a little cold water on VR using current commercial hardware
The inimitable Michael Abrash dives into the challenges of latency in modern hardware. Absolutely fascinating stuff for those interested in the various limitations of modern display technologies like LCD, OLED, and laser scanning, as well as a host of ideas for ways to cheat through the limitations without display technologies custom-designer for virtual reality (which may yet happen, but is certainly a ways off).
Update: The Oculus Rift team made a little update about what they've done to improve their latency: custom sensor IC.
