So you were wondering what AMD's reaction to Nvidia's new PhysX-enabled drivers would be? According to software manufacturers, it's AMD's own fault for dismissing physics engines.

|Mark called it ironic that nobody cried foul when Epic released the UT3 Bonus Pack, which contained PhysX-enabled levels and required an Ageia PPU to run. Nvidia’s purchase of Ageia made this technology available to millions of gamers, instead of several thousands (according to some sources, Ageia shipped only 120,000 boards).
To us, there is a clear conclusion of this matter. AMD rained on its own parade and the launch of its excellent 4850 and 4870 cards. We got the impression that the software vendors in question believe that their products benefit from GPU physics and that accelerating in-game physics with a GPU was a positive move. Forget corporate politics for one minute and figure this one out: Nvidia modified PhysX and brings it to millions of owners of GeForce cards. We would say around 10 million, since we do not think that 8600 versions and below are capable of serving PhysX demands with graphics.
If you own a GeForce 8800, 9600/9800 or GTX 200 series, we can only recommend a download of the latest drivers and PhysX software when they become available and start playing those levels in Unreal Tournament 3, Ghost Recon and other PhysX games.
