    Interesting. I'm amazed that there are titles in the works that take advantage of this technology and this is the first we're hearing about it.

    So how would it work - the CPU does the AI, feeds the PPU which in turn feeds the GPU?

    I'm assuming the Novodex physics API will have software fallbacks for those without these add-in cards right?

    I don't even want to imagine the name of a Gainward card with integrated GPU and PPU :)

    I wonder if 3DRealms is going to rewrite half of DNF to take advantage of this? lol!

    Still very cool, my only concern is the amount of bandwidth that will be needed to move all the physics data between the CPU/GPU/PPU. With PCIe it shouldn't be a huge problem, but with PCI I just can see how it's feasable.

    Now why aren't Nvidia and ATI doing this?

    Maybe because they only have so many resources? Maybe they don't have access/experience with physics engines?

    Just had a quick look but are other Physics engine's able to take advantage of this like Havok or would they have to be rewritten? Is this proprietary as well - the Chip plus the API? so any other Physics engine would need to license it to be able to use it?

    What a great idea :D
    Looking forward to this sort of thing being properly utilised.

    Coming soon to a DirectX release near you: Direct_Physics :twisted:

    I just glossed over the pdf linked at the top. It mentioned that it would provide a better solution than running physics calculations in parallel on a separate CPU core. Given that current CPUs already have vector processing functionality, it is safe to assume that a dedicated physics processor would incorporate something further. What immediately comes to mind is something analogous to the various fixed function pipelines (T&L, texture filtering and compression, etc) in graphics cards.

    Does this sound right?

    Looks like just a math chip with lots and lots of parallel math units.

    Cool they have a fairly neat downloadable demo.

    http://www.ageia.com/novodex_downloads.html#

    Wow the rocket demos are most impressive. Shows how badly we need a wicked geometry processor.

    There are 47 demos. Some of the Geometry demos have dominos that you can knock over and hundreds of dominos fall over. There are also exploding buildings made of thousands of bricks.

    The rag doll demos are kind of kool as well because they seem like they are made of rubber.

    The road kill demo is interesting.

    The tread is really cool.

    so not only the XBox2 will have an PPU. Cool.

    Not until you just mentioned it. :?

    Back on topic:
    FWIW, here's an earlier thread on the same topic/software.

    Is Havok going to support this?

    Maybe you should get some work done instead then? Hang on a minute I'm at work too.. :lol:

    Regarding this processor, is it going to be available for the PC Platform too?

    How do you know Xbox2 will have a PPU?
