Wow!!! Worlds best physics engine in Intel hands…Larrabee? 8O)
Hm… will AMD acquire Ageia now? :roll:
…and what would nVIDIA do then?
Hmm, maybe Intel will do like Ageia and release it free for noncommercial use 
I must say untill now that the physics behaviour of PhysX is quite good.
Havok performed a lot worse when I used it with macromedia director, but that was only a subset of havok or course.
Just take a look at the version of the Havok XTRA in Director and you know why. They never updated it since the release and oh i almost forgot, they used to “forgot” to renew the licence before shipping new versions of Director. Well, at least if you’re stupid enough to buy this. Still it can perform certain tasks like concave mesh collision. Havok in Virtools was already much better, not even talking about a v2.x. Havok is the most complete physics engine so far.
Well, I won’t be using it since I’m moving all development stuff to unity right now and am quite happy with physX. Maybe I’ll also never find the weak points of engine A or B because I actually make rather SIMPLE stuff.
Then feel happy. Contrary to you i need this functionality and would be more than glad seeing more of PhysX functionality beeing exposed in Unity.
Havok is without any doubt an excellent physcis engine. Just have a look at this super sweet deformable and breakable objects demo.

But it also comes with a quite high price tag. If I remember right a Havok license costs 100.000$+. So if they don’t change their business model after the Intel buyout it will probably stay a AAA games physics engine.
Bye,

P.S. I would be already happy if Ageia would official stupport the Mac platform with their free PhysiX SDK 
Although I wouldn’t complain about a affordable Havok license too. 8)
If the Ageia PhysX engine was good enough for Unreal3 engine - it’s probably a safe bet that’s its good enough for a AAA game too! - I was very unimpressed with Havok’s limited version in Director. And the PhysX in Unity has been great for me. The price tag couldn’t have been better unless they paid me. xD
Cheers,
I would definitely say PhysX is the #2 physics engine in the world
It seems that they get down to business with their raytracing engine. So, they need also physics, of course.
That demo always bugged the heck out of me because of the wood breaking part. You can clearly tell that the wood that they are claiming randomly generates the breaks and things, is actually just a higher resolution pre-broken board.
the new physics engine that some current game dev tools r going to employ is Newton Game Dynamics.

it seems to work in an untraditional way. its relatively new though, and maybe needs some time to mature.
I here the Bullet physics engine is quite good. I think they’ve developed an optimized PS3 version (which hasn’t been released) also.
I’ve used Newton once and whilst it wasn’t the fastest one, it was quite flexible.
