The Irrational Games Website now features a Q&A on the recently revealed specs for the PC edition of BioShock Infinite, their upcoming first-person shooter sequel. There are a few answers covering Steam support, saying that Steam is required, Steam's standard DRM will be used, and boxed copies will include Steam keys. They also say the game will have full widescreen support and will be able to play at the maximum framerate supported by your system, and discuss OS support, saying it will be Window 8 "compatible" and not "certified," and that there will be no Windows XP support.
