Oculus Rift is the headset that started the current hysteria. Developed by Palmer Luckey, funded via Kickstarter and snapped up by Facebook for a cool $2 billion, the Rift plugs into your computer's DVI and USB ports and tracks your head movements to provide 3D imagery on its stereo screens. The consumer edition Rift uses a 2160 x 1200 resolution, working at 233 million pixels per second, with a 90Hz refresh rate. It's high tech stuff, which matches the HTC Vive for refresh rate, but lags behind PlayStation VR. However, given its access to the power of latest PCs, it will be pushing a lot more pixels than Sony's headset.
