“Nvidia works very closely with The Khronos Group,” said Mohammad, explaining that “actually Neil Trevett is president of the group and he’s part of Nvidia - so we’ve been driving that standard also, and it’s an excellent standard.” What’s more, later on, Mohammad also described Nvidia’s future plans for PhysX by saying “as and when we do move to OpenCL,” which implies little doubt that Nvidia is seriously considering this as an option.

good, if physx starts working on ati cards as well, so much better for nvidia.

And AMD. Our resident nVidia-PR-spokesperson keeps touting of the GeForce superior featureset. This would give him one less reason to slober nVidia's knob.

Yep.

This is good news.

I'd agree it would be a good thing. Get one standard that can work across the board so developers will want to use it.

yes, good for amd as well, what i was trying to say physx doesn't have good chance of surviving if it stays on nvidia cards only. it should have worked on both brands of card from start.

Nvidia has been trying to encourage support for physx on ati cards. ^^ I recall a user was building a driverset that would support physx on ati cards and nvidia was actually giving him email support assistance.

Physx is far more then just another bulletpoint on nvidias video card box's, its a while new product that they are trying to synergize with their video cards. They are banking on the hope that with more video card support, more game makers will likely support the physx protocal, and that while ati cards will support it, nvidia will be there with the better driver support, performance, ect. Also with the added game support, game makers will be getting nvidias logo.

A little risky but imo, about damn time. We need to get this shiat standardized.

In the long run we will probably see Havok + PhysX acceleration on both ATI and NVidia, but probably a bit better performance with their individually supported physics api (i.e. ATI slightly faster with Havok, and NVidia slightly faster with PhysX).

considering no ones doing havok hardware accell, I can't see that happening.

thats a whole lotta speculation of may and may nots there. It seems AMD expressed interest, with no official release.

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/hardware/2009/03/27/amd-demonstrates-gpu-physics-at-gdc/1

Havok on GPU was announced and demoed ages ago.

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 (http://gamevideos.1up.com/video/id/24095) 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. :p

Well PhysX + GPU is good. :p

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.
