Gaming company Razer and professional VR company Sensics are heading an effort to standardize virtual reality development called the Open Source Virtual Reality (OSVR) platform. It is an open source software platform that encompasses multiple game engines, head mounted displays and control schemes. While you might be able to make a game in Unity and port it to multiple devices, VROS does the work of optimizing it for each device. Around two dozen companies and organizations are listed supports and plugins are in the works for Unreal Engine 4 and the Unity 3D Engine. At the centre of this project is the OSVR Hacker Dev Kit, a new head mounted display that is less polished and more flexible that the Oculus Rift, specifically designed for testing games and peripherals.
