NVIDIA announced today that its popular PhysX technology is now available to all registered PS3 developers free of charge. Used in titles such as Unreal Tournament 3 and Rainbow Six Vegas, the SDK sports a feature-rich API and robust physics engine. Previously only companies signed on with NVIDIA had access to it, but as a result of an contractual agreement made with Sony, the middleware can now be downloaded through the official SCEI developer network by all licensed PS3 developers.[blockquote2]"NVIDIA is proud to support PLAYSTATION 3 as an approved middleware provider," said Tony Tamasi, senior vice president of content and technology at NVIDIA. "Games developed for the PLAYSTATION 3 using PhysX technology offer a more realistic and lifelike interaction between the games characters and other objects within the game. We look forward to the new games that will redefine reality for a new generation of gamers."[/blockquote2]What does this mean for us? Not a whole lot. Might be seeing more games that take advantage of PhysX on PS3 in the future though.
