No games are being announced that supports ATI's method, says AGEIA

Earlier this week at Computex, DailyTech reported that ATI officially announces its solution to physics processing. Called Triple Play, ATI's solution depends on three Radeon X1K series cards, two of which operate in CrossFire mode while a third card is configured for physics processing. The Triple Play solution, says ATI, uses the raw gigaflop performance of the Radeon X1K series to process physics, but users are concerned at the approach. The fact that customers are forced to buy three ATI boards ended up being questionable for many users as costs quickly escalate.  A system with two Radeons can still use one for physics calculations, but it is no longer dubbed Triple Play.

FiringSquad this week reported a response from AGEIA which attempts to explain the lack of value in ATI's solution. According to AGEIA, measuring the performance of physics processing by simply looking at the number of gigaflops in a GPU is analogous to saying that "the more wheels I have on my car, the faster I will go." AGEIA's vice president of marketing,  Michael Steele, said to FiringSquad:
  • Graphics processors are designed for graphics. Physics is an entirely different environment. Why would you sacrifice graphics performance for questionable physics? You’ll be hard pressed to find game developers who don’t want to use all the graphics power they can get, thus leaving very little for anything else in that chip.
  • “Boundless Gaming” is actually enabled by AGEIA’s Gaming Power Triangle in which the PhysX processor adds true physics to the mix instead of leaving it to a repurposed graphics processor.
AGEIA further says that developers are announcing more and more games that support its PhysX product, while no one is announcing support for ATI's method. Steele also mentioned that while he's glad that ATI has agreed that physics is important, ATI is delivering a "questionable" solution to physics processing.

Steele also emphasized that PhysX is available now while ATI's solution is not.

If nVIDIA and ATI are both working with Havok, chances are that their SDK will be close, and Directx 10 will probably set some standards, ATI also showed up some benchs with nVIDIA cards so they have tested their solution on nVIDIA cards as well.

With H:FX one card takes cares of the physics the other of the graphics, soo the burden is close to exactly the same has using on graphics card + PPU.

Shitty implementation or not, the facts speak for themselves.

I can find where I've read that about CS:Source so forget what I said, however I’m pretty sure Valve is doing some homework when it comes to Physics, not just Valve but ID, Crytek and all the others that DIDN’T say they were going to support Ageia, and CryTek already showed up a new demo with some advanced physics without mentioning Ageia…

Why do people keep saying ATI is working with Havok? I don't remember reading anything that even implied that. I have also searched ATI.COM and found that the ONLY mention of Havok on the whole site (including press releases) was for a piece of modeling software.
