id Software technical director John Carmack has unveiled a tech demo of Rage running at 60fps on iPhone during his keynote at QuakeCon 2010. It took Carmack two weeks to get the demo up and running. It will form the basis for a small Rage title on the platform sometime later this year. There will be a second Rage iPhone game out next year alongside the PC, PS3 and 360 versions.
The game’s final frame-rate would be similar to Doom Classic but better than Doom Resurrection. Apparently it will also run on the original 2G iPhone, so doesn’t require the iPhone 4 and iPad like some apps doing the rounds.
