Virtual reality company Oculus has started shipping the next version of its VR headset, the Oculus Rift Developer Kit 2, to buyers. The DK2, which Oculus says more than 45,000 people have pre-ordered at a price of $350, is set to be the final development model before the Facebook-owned Oculus releases a full consumer version of its Rift headset. Most noticeable is the step up in its display — where the first Rift developer kit displayed a painfully low 1280×800 screen resolution, the DK2 gives users a 1080p OLED panel.
