[ http://www.gamespot.com/xbox360/action/farcry2/news.html?sid=6196418&mode=previews ]The developer says that the PS3, Xbox 360, and PC versions have been developed from the same core build, so they'll all share the same features. While we didn't see the PS3 version, it's claimed that the aliasing on Sony's machine outperforms that of the 360, while on the PC it's all dependent on the specifications of your machine.
Sounds interesting , especially when you remember X360 has a 10MB eDRAM [ which provides free AA ? ] ...
