Virtual reality game development is a hot button topic, and few studios have been experimenting with VR games longer than Valve.

The firm has been creating advanced prototype VR HMD's since mid-2013, and Valve engineer Alex Vlachos believes that experience has afforded him and his colleagues a ton of unique VR-specific rendering knowledge.

At GDC 2015, Vlachos took the stage to share that knowledge with VR-curious developers and deconstruct the unique rendering challenges that come with VR game development.

Beginning with the basic requirements of VR rendering, Vlachos walked his audience through topics like efficient stereo rendering, reducing rendering latency, constrained anisotropic lighting, and other practical tips and tricks relating directly to VR rendering performance and quality.

It's a fascinating talk that runs down a ton of technical insight in just over an hour, and now you can watch it for free over on the GDC Vault.
