It seems AMD/ATI really want to support the porting of PhysX on Radeon:
“We think that it is great that people continue to use our products in creative ways.”
When we’ve spoken to AMD it doesn’t seem like that AMD doesn’t want this to happen, on the opposite, anything that could add more value to the already affordable Radeon HD 4800 series is a plus.
After playing with Nvidia’s CUDA SDK and PhysX SDK, Eran Badit (NGOHQ.com) apparently got the PhysX layer to play along with Radeon cards. He mentioned that enabling PhysX support on Radeon cards is not particularly difficult, leading us to believe that physics on graphics cards may not so much be a technology problem but a game of politics.
Eran said that he will be offering the ATI PhysX-enabling utility on NGOHQ.com as soon as he gets his hands on more hardware to check the application on more than one graphics card. We are told that he is testing hardware already, which means that the software should be available “soon”.
