1) No you obviously don't know why as its the same reason why i have been editing out some of your comments, your not sticking to the point im making "you can turn it off ect... at any criticism," and the AMD part of your post has been done to death.
2) I agree with upto the free for the competition no one is asking for NV to give PhysX free to AMD but yet you and other keep saying that. Letting the NV card in a system run PhysX while having an AMD card in the system is not giving the competition anything.
Again done to death.
1/ I do know why

I see your posts on many forums. I don't have to stick to the point you're making, because there's more to the story than the point you're making. There's no reason to edit my posts, I stand by what I said.
2/ I didn't say AMD or anyone else is asking Nv to give them "free PhysX", go ahead and quote me saying that if you can.
I was explaining the reason why Physx is proprietary, which is causing its stagnation in progress.
IF AMD licenced it, more games would use it, and there would be more progress.
OR if there was competition there would be incentive for more progress.
OR if it was open, more games would use it, and there would be more progress (but as we both now know Nv will not do that for the reasons I outlined above).
Knowing that Nv will not "open it for free", the only options to promote strong progress are strong competition, or licening. Without those, PhysX will continue at its current pace, being an after thought tacked on to games, primarily because games cannot be built from the ground up around PhysX due to the inability of a large user base to use the effects.
Competition helps people and Companies that need it to progress, some of us progress regardless of the state of the Competition.
Maybe they do, and thats nice. You know what else? some dont do anything at all, stagnating progress.
