[UPDATE] Bethesda has issued a statement saying that John Carmack will continue his role at id Software.
"John has long been interested in the work at Oculus VR and wishes to spend time on that project. The technical leadership he provides for games in development at id Software is unaffected," said a Bethesda spokesperson to GameSpot.
"My time division is now Oculus over Id over Armadillo," said Carmack on Twitter. "It is a big change of pace to go from working on carefully engineered code for the long haul to PANICKY STARTUP CODING FOR THE NEXT DEMO."
The original story is below.
John Carmack has taken a full-time job at the company making the Oculus Rift.
Carmack will now work full-time out of Oculus VR's new Dallas office as the company's chief technology officer.
“The dream of VR has been simmering in the background for decades, but now, the people and technologies are finally aligning to allow it to reach the potential we imagined,” said Carmack in a public statement.
“I’m extremely excited to make a mark in what I truly believe will be a transformative technology."
The development kit for the Oculus Rift VR headset began shipping in March 2013. No date for a consumer version of the technology has currently been made available.
Carmack was one of the co-founders of id Software in 1991, and has served as technical director at the Doom and Quake developer for over 20 years. The studio was independent until 2009, when it was acquired by Bethesda parent company ZeniMax Media.
id Software is currently working on Doom 4.
