According to Steam's hardware stats, the most common video card at the moment is the Intel HD 3000, which most games are optimised for. They've probably been developing this for a few years now, especially if they've built a brand new engine (my bet is they're nitpicking from the *horrible* TS3 engine or using a variant of SimCity's Glassbox), so I'm guessing they're going for the lower end, integrated models which ironically enough is owned by most of the game's core target audience.
