It depends on how developers use it. But I think that anything that makes environments more immersive would be great. Last night I was playing GRAW, and my friend Steve was hiding out behind a create. It would have been great fun to kick the crate and have it push Steve into the water!

I can't remember off hand where I read that, so take it with a grain of salt! I'm, oh, 60% sure I guess. :) As well, I'm 95% pretty sure that Havok is also available to PS3 developers.

What is unique is the hardware solution provided by the Physx libraries. I'm curious but I'm a little reserved on this thing though. Can it actually benefit gameplay? iSaw a comparison video of GRAW explosions running w/ and w/o the add-in card. W/o the add-in card the explosions were pretty weak but w/ it, they looked more convincing. iAlso noticed that it looked exactly like the explosions in the X360 version of GRAW. iDon't know if Physx is available for X360 developer but clearly the system is very good @ physics calculations as well if the video iSaw was any indication. iTHink the X360 dev use havok, a competing library. Anyway, from what iRead, iSeems like this will b more of a visual thing that something that will fundamentally improve the dynamics of gameplay. That could change but iCheck it out on my friend's computer 1st. He always gets the latest toys and I'm sure he'll buy this. Physics libraries have been around for a long time; this is nothing new.

Game developers, when they write the software for their game, can tap into the PhysX software to do physics stuff. On a PC, the PhysX software knows all about the PhysX hardware card, and gets the hardware card to do all its dirty work. In the case of the PS3, the PhysX software library has been modified. Instead of talking to the PhysX hardware card to do the dirty work, it gets the Cell processor to do the dirty work. The Cell is very good at this kind of thing (much better than a general purpose processor like the Pentium). So to a programmer, they just have to use the PhysX software library, and it will do the rest. A programmer who knows how to use PhysX on the PC will probably know almost everything he needs to know to do the same thing for the PS3. The PhysX library is a bunch of software.

How can the ps3 have physX abilities without the card? Also, its been said that the physX (card) when run on a pc can free up with cpu and gpu by something like 40%, so more things can be pulled off. Can the same performance increase be accomplished by just running physX code on the ps3? Henning, please elaborate. How can the ps3 have physX abilities without the card?
