It says physics, not physX. With OpenCL, you can perform many of the same calculations as CUDA, which PhysX is based on. What's written is true, but won't work with PhysX due to PhysX being written in CUDA and not OpenCL.
i'm aware of that. when i see it for the first time i'm wondering what game already did use ati card for it's physics calculation because i never heard one. at one time i think it might able to calculate physics that normally done with cpu such as HAVOK using the gpu because there is still no game incorporate bullet physics back then
