We've talked about ATI's physics, and we were quite surprised when Godfrey Cheng, AMD's Director of technical marketing at Graphic product group confirmed that Nvidia never really offered PhysX to ATI.
Despite the fact that Nvidia said many times that it wants
to give PhysX to all that want it, they never contacted ATI through proper
channels. Nvidia did voice out, at least to journalists, that if you want to
embrace PhysX you need to adopt CUDA, which is not an open standard. AMD / ATI are really not big fans of such proprietary standards.
ATI has already said that it gave its heart to Havok. Despite the fact that Havok is actually Intel’s, it looks like this works quite well between Intel and AMD. We will certainly watch for the
development but we heard that it is now up to games developers to program GPU Havoc
for ATI cards, and it looks that this will happen at some point in future, but
this future might be in 2010, even ATI was not ready to talk about when.
