You may know Ageia, you may not, but for those who dont, Ageia is a company that makes GPU's that enhance physics models. As of three months ago, we thought that for the next gen of games, we may be useing Ageia cards. However ATi and nVidia didn't want to hear that their market was going to be stolen by a company worth about 1/3 of a new card launch. So they figured out how to put a physics engine into their cores, and now the ATi X2K, and nVidia 8 series will all have physics acceleration. Poor Ageia is again thrown to the back by the big boys.
But who knows, Mabe Ageia's new core will magically outbench that of ATi and nVidia, or mabe it will be cheaper, and attract people that way. Who knows.
Cheers
