Physx is a very, very good physics engine (currently playing Project Cars with it, and the cars feel VERY good... actually, does anyone know if physics from a game like PCars could be ported to another game running Physx3?) so this is good news. There was some concern that the game was using APEX, the GPU side of Physx, which only runs well on Nvidia cards but others have explained that at least the core engine will run equally well on both ATI and NVidia.

Physics still need to be improved, but they are probably going to improve on full release.
