I have a Radeon HD 5670 GPU. And I heard some where that you can run PhysX on an AMD GPU. But I can't find anything about it. So I hope you can help me. Also is it possible to activate PhysX with only an AMD card?
Also this is my CPU: AMD Athlon II x4 620 ~2.6 GHZ
Also is it possible to activate PhysX with only an AMD card?
That is the only question you asked. YES, it is possible. It is just difficult to run.
Let's not go ruining things. NO, you cannot run PhysX "ON" an AMD card. When PhysX is run with an AMD card present (and without a dedicated Nvidia PhysX card), PhysX is run on the CPU. It never runs on the AMD card itself.
