As usual, GameSpot didn't forget to pack their camera for QuakeCon, and so they have now posted a video interview with John Carmack, id Software's lead programmer. The conversation is available in four segments in several streaming formats, totalling nearly 24 minutes, and John talks about graphical effects, realism in games, the new Doom game and the features it will require in 3D accelerator cards, his current programming challenges, the future of computer graphics, and lots more.
