so,, what I know that PhysX is there to show you shattering glasses, torn clothes etc. and is that it ? What about other kind of physics like movement of a car on a wet road, falling of buildings depending on where the explosives are placed ( the way we see in Red Faction) is that not taken care by PhysX ? If yes, then how do ATI cards deal with it when they do not have PhysX ? If no, then which is that component which takes care of all this ?

There are only about 20-25 games ever made, that use GPU accelerated PhysX. Physics are normally handled by the CPU while your GPU handles rending the graphics. Some new games are using DirectCompute or OpenCL to allow the GPU to do more advanced stuff the CPU isn't fast at as well.

Unless you play those 20-25 games, it doesn't matter and even in those 20-25 games, the effects used by PhysX varies from pointless to very good with far more somewhere in the middle. I personally have not played a game with GPU accelerated PhysX that I play with it on. Of course I don't have Mafia or Batman AA, which are supposed to be good with it.

what puzzles me is .. why a total dedicated component(PhysX , Open CL) is developed for those few games, that too with effects which are hardly visible. I played Mafia and all I could see for PhysX was in some gun fight, if u shoot at glass or walls, you can see some shattering effect and thats it. Is it really worth that much ? Particle physics can be interesting however not at this prize. Given a choice, I would like to see more different kind of physics such as heating up of tyre and its effect on the vehicle when running fast, motion of a bullet thru wind, ( little bit of it we had in Sniper, but not in very great detail).. and likewise I think there can be lot of places Physics could be imporved in games. So just dedicating on a shattering effect seems little pointless to me.

there's a few more than 20-25 games that use physx. also, Havoc physx can be run on ati cards.... different physx than nvidia ( can be displayed by nvidia card ) ........ is physx good, yes! it brings more to the screen than not having it. play with and without..... how's the gaming experience ?

I did specifically say GPU accelerated PhysX. Nvidia does have a gaming engine that can be used that supports PhysX, but it will only use the CPU, which works on any computer the same, or with GPU Accelerated option, which only a few games take advantage of. I know for a fact many of those do not use GPU accelerated PhysX, as I do own some.

Here is Nvidia's list:
