Its because physx runs on the nvidia gpu and when using a amd card it runs on the cpu. With a powerful cpu the physx we have seen in games should run pretty well but most would tell you that nvidia make sure cpu physx is gimped to make there gpu physx look better than it is.
The message is simply to buy a nv gpu if you want physx.
Well I agree but you could say the same for AMD... The fact is that physx is less in your face when compared to the TressFx issue with the hair... when you think about it should the CPU be able to handle TressFx pretty well then as well?
