The 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 the latest PCs, it’s pushing a lot more pixels than Sony’s headset.
