Or gpu if the driver it's adapted

And if Rege did this it will work. There are few that can mod drivers like him even though his attitude and maturity sucks

Not that it's somehow less impressive without the hardware...but I just don't understand why they wouldn't have run it on the CPU or GPU or both from the start.

Well, the AGEIA PPU is a dedicated processor that does nothing but accelerate PhysX. In the "GPU" solution, PhysX processing is done by some of the stream processors in the GPU.

So, in games that really stress the GPU to its limit, using GPU acceleration will cut down on its performance since some of its stream processors will be used to accelerate PhysX. In this case, a dedicated PPU like the AGEIA PhysX card will allow physics to be accelerated without any effect on the GPU.

Of course, not many games can fully utilize cards like the GeForce 9800 GTX or the new GTX 280/260 cards unless you are rendering at very high resolutions and with anti-aliasing enabled.

Actually, if the technology is open for development, it can be adapted to run on any general processor, like a CPU or a GPU based on a unified architecture. PhysX is proprietary technology, like Havok Physics. That's why NVIDIA can only implement it after they bought over AGEIA.

It's really not about the hardware, although the AGEIA PhysX card is a dedicated processor that does nothing but PhysX processing.

Not sure I think I have a fan

That makes sense...but looking back at it and the slow takeup of the Physx technology in games, the primary problem with it (certainly from a gamer's point of view) is that they had to buy *another* piece of hardware to stick in their system to get to use it. And then developers looked at that fact and wondered how many gamers would fork out another ~$150 or so for that extra piece of hardware, and probably then thought it was considerably less worth the effort.

I'm just thinking that if they'd produced it as a software technology that didn't increase the cost to the user by forcing additional hardware that they would've gotten much quicker/better market penetration.

Oh...and then maybe released the add-in card down the road once they had a reasonable market presence..."You know how Physx made your games more awesomer? Now with the Ageia Physx add-in card, the awsomerness gets cranked up to eleven!" Then they might have gotten more traction with the add-in board because they would have built a base of enthusiast gamers who had "seen the light." and might be ready to invest more in it.

yeah but here i must agree with rege
i know that he can set it up to work and i know that new gpus have physx
all new gpu are made t be reprogramed and that is not hard thing to do
any way this will work without any problems
