Doom 3 on the original OG Xbox is a port of the original PC game from 2004. However, just exactly how do you port a game from the PC that demanded lots of memory and a fast CPU and GPU, to an OG Xbox with a 733Mhz CPU and just 64Mb of RAM. In today's episode, I talk to an ex-Vicarious Visions developer who lets me know how it was done, and how Doom 3 on the OG Xbox could be a candidate for an impossible port. Please enjoy!
