In a keynote speech at QuakeCon 2010 today, John Carmack of id Software demonstrated an impressive iOS version of its upcoming Rage first-person shooter running on an iPhone 4. Primarily a proof-of-concept at this point, the game was shown using the id tech 5 game engine running at 60 frames-per-second, which Carmack described as a “similar or better frame rate to Doom Classic [and] significantly better than Doom Resurrection.” Carmack noted that he “did some fairly clever things to approximate sub-pixel precision on the movement” and that the games also look “incredibly cool on an iPad” and can even run reasonably well on an original iPhone.
He went on to mention that with the capabilities of modern iOS devices he can “kill anything done on a previous-generation console like an Xbox or PlayStation 2” with the biggest limitation of the devices being battery drain—Carmack notes that id Software will need to offer a 30 fps option in their game engine in order to deal with this. Carmack also mentioned that id’s iPhone titles have been doing well for the company and that it plans to continue developments for the iOS platform.
During his keynote, Carmack also provided some insight into Apple’s general approach to gaming on the iOS platform, mentioning that “at their heart and core they’re not really a game-friendly company” and that it was an “eye-opener for Apple that gaming has been big on their platforms.” He went on to say that although there are gaming advocates at Apple that he speaks with, such as Quake III Arena designer Graham Devine, Apple as a company remains resistant to making hardware changes specifically for gaming. As an example, Carmack describes touchscreen and graphics delays on the iPad while running the Rage demo and strongly believes that this indicates room for improvement in Apple’s engineering.
