Very impressive stuff from inside John Carmack's pocket.
The big surprise that John Carmack teased about earlier today was revealed during his keynote at QuakeCon 2010.
We all know about how well the id Tech 5 engine runs Rage on the Xbox 360, PlayStation 3 and PC, but Carmack pulled another platform out of his pocket to demonstrate the new megatexture engine – the iPhone 4.
The big stunner is that the game is able to run on the iPhone 4's A4 chip at a full 60 frames per second, while featuring several lighting effects that we associate with modern GPUs. Even more impressive is that Carmack said that the id Tech 5 engine even runs acceptably well on the original iPhone 2G – not just the beefier CPU and GPUs of the 3GS and newer.
Incredibly, Carmack said that the id Tech 5 engine even when running on the iPhone could "kill anything done on the Xbox or PlayStation 2." How's that for amazing progress?
