Next Steam announced a new service called Stream Link, which allows you to stream Steam content from any PC or Steam Machine on the same home network. It supports 1080p at 60Hz with low latency, will be available November for $49.99.

Valve's VR Headset, meanwhile, will include two new technologies as part of the release: a room scale tracking system codenamed Lighthouse, and a VR input system.

Finally, Vavle unveiled its Source 2 engine, the successor to the Source engine used in Valve's games since the launch of Counter-Strike: Source and Half-Life 2. The company will also be releasing a Vulkan-compatible version of the engine.
