Oculus CTO and id Software co-founder John Carmack believes the dawn of widespread mobile VR technology is close. Many game developers agree, and they're scrambling to sort out how to design compelling games and experiences that take advantage of the unique advantages (and shortcomings) of contemporary VR headsets.

At GDC 2015, Carmack offered them some concrete advice by sitting down to chat about the technical details, techniques and strategies you should know to improve the quality of your VR games, applications, and experiences.

He also shared some thoughts on the future of VR, including what it means for the mobile ecosystem, and answered questions from the audience for as long as he could.

As usual, Carmack's talk was thorough, frank and done completely without notes. It was also quite lengthy, and if you missed seeing all 90 minutes of it in person you can now watch it for free over on the GDC Vault.
