But, where were we ... oh, yes! Doom Resurrection! This sure sounds like the "graphical tour de force" he promised to bring to the iPhone. Carmack & Co were able to reuse much of DOOM 3's assets (downsized for the iPhone's screen resolution, of course) and get the engine running at 30 frames per second on the latest iPod Touch. Wrapped around that fancy tech, they've built "eight full levels and about five hours of game play" – the future iPhone 3.0 OS release will also enable "peer-to-peer cooperative multiplayer" for some on-the-go Deathmatch.
One of the most notable takeaways from VB's interview: Carmack's assertion that the iPhone is "a real game platform, not a tiny little toy." He explains that "the iPhone should be better in performance than the Nintendo DS and the PlayStation Portable" in raw horsepower "but the truth is you can't exploit it all because of software inefficiencies." We imagine the newly Open GL ES 2.0-compliant iPhones (gallery below) will ameliorate much of Mr. Carmack's concerns. In the interim, check out how far he's gotten on today's hardware when Doom Resurrection shoots the AppStore in the face next week.
