Epic’s graphics guru Tim Sweeney on AR/VR, game engine wars, and simulating humans

Tim Sweeney, the chief executive of Epic Games, has seen computers become 100,000 times faster during the 25 years he has been making games. And he’s one of the few people in the world who knows what to do with all of that computing power and can predict where we’re heading.

His company of game designers has created titles such as Unreal Tournament and Gears of War, and it’s working on the upcoming Fortnite title. Epic also creates the Unreal Engine 4, a tool that makes it easier for other developers to create beautiful games with amazing worlds and realistic human characters. Epic’s Unreal is the engine of the game industry, and Sweeney is the one of the brains that makes it happen.
