GDC 2015: Valve Announced Source Engine 2, Link, and Lighthouse VR Tracking System

Products and Technologies to Continue PC Gaming Momentum
At this week's Game Developers Conference (GDC) in San Francisco, Valve announced a new product called Steam Link, which is designed to extend your Steam experience to any room in the house. Steam Link allows you to stream all your Steam content from any PC or Steam Machine on the same home network. Supporting 1080p at 60Hz with low latency, Steam Link will be available this November for $49.99, and available with a Steam Controller for an additional $49.99 in the US (worldwide pricing to be released closer to launch).
Steam Machines from partners Alienware and Falcon Northwest are being shown, with Machines from a dozen other partners slated to release this November. Steam Machines will start at the same price point as game consoles, with higher performance.
Valve is also showing HTC Vive, a VR headset officially revealed a few days ago and scheduled to be released by HTC by the end of the year. Two new technologies are part of the VR release - a room scale tracking system codenamed Lighthouse, and a VR input system.
In addition, Valve unveiled the Source 2 engine, which will be available for free to content developers. The company also revealed a Vulkan-compatible version of the Source 2 engine. Vulkan is a cross-platform, cross-vendor 3D graphics API that allows game developers to get the most out of the latest graphics hardware, and ensures hardware developers that there is a consistent, low overhead method of taking advantage of products. Vulkan, previously called Next Generation OpenGL, is administered by the Khronos Group, along with other standards such as OpenCL, OpenGL, and WebGL.
