The portfolio of Havok is quite interesting: http://www.havok.com/content/view/72/57/

EDIT: Havok with GPU acceleration http://www.bit-tech.net/news/hardwar...ysics-at-gdc/1

In the form of HavokFX, which was scrapped, THAT was ages ago.
Then again sorta secretive with something else, not a ressurrection of HavokFX, for quite a while ago (a year or so maybe?), then 10 days ago some guy at AMD or ATi mentioned they were gonna show some stuff with Havok on GDC.

One thing specificly mentioned as GPU assisted was the cloth demo they showed with the dancer, with OpenCL capable of running on pretty much anything, it was running a quad core and unspecified ATi GPU.

Who knows when this will be a finished product, but NV has enjoyed their time as one sided supporter of the only GPU accelerated physics engine on the market, now that competition comes along from a well established competitor who´ll run on anyones GPU, if they want to acctually compete with PhysX instead of selling GPUs with it, they´re prolly gonna have to open it up with OpenCL.
I think they rather banked on ATi not supporting CUDA and by extention PhysX´s GPU part when they offered them to do so, its been great marketing stuff for them really.

Havok has seen that NVidia did get a positive reception with Mirror's Edge PhysX support, which have made them more anxious about getting into the GPU market. This is my guess, but it's just speculation.

They still have several giant games with software support, like Blizzards SC2+D3. But if people suddenly seem to think that PhysX + GPU is good, then Havok can get into trouble.

Well PhysX + GPU is good.

Especially with two cards indeed. With one card it is more of a balance of performance, but with right programming they can get it right there too.
