    Good news for folks with a GeForce 8 GPU and lots of questions about how the recent Ageia acquisition would affect them: your current card will be receiving PhysX support. When NVIDIA CEO Jen-Hsun Huang was questioned in a recent conference call, he noted that the firm was currently "working towards the physics-engine-to-CUDA port," and it could be delivered as "a software update" to every card that's CUDA-enabled (read: all of the GeForce 8 GPUs). Sadly, the bigwig still wouldn't say when to expect the release of the first PhysX port, but we really can't imagine it taking too awfully long now.

    Lol, as if Nvidia isn't planning on doing the same with their onboard chips...

    This is not only good news for Nvidia users, but good news for everyone.
    You see so many games that Nvidia has influenced to build around their drivers and cards, that now more games will be made to take advantage of the PhysX engine that we may be able to use our present PhysX cards on more games

    so, now my question is - if the GPU on an nVidia card is going to impliment physics support - will it be able to run those routines while rendering? and if so, how much of a performance hit will it have to take?


    On the other hand, ATI has already demonstrated how their GPUs can run physics implimentation quite well - I wouldn't be surprised to see ATI start releasing physics capable Crossfire drivers in the very near future . . . I even wonder if they'll try to partner up with Intel/Aegia.

    That's up to the developpers. The developpers have the choice to add extra physics with an acceptable framedrop or the developpers can use the PhysX card to improve performance for existing physics.

    Unreal Tournament 3 performance is much better with a PhysX card because Epic programmed the game so that the game uses the PhysX card to render Physics that would normally be rendered by CPU/GPU.

    If every developper uses the PhysX card to add extra physics without reducing framerates ( the perfect balance ), then it would be great.

    Most developpers like to add more physics and don't really care about the framedrops...

    We can't deny that NVidia does have a better shader architecture throughout their DX 10.x lineup. When rendering a scene, a few unified shaders can do physics, afterall they're fully programmable shaders.

    Good news for me :D

    exactly, i see no reason why you couldnt for example, take a G92GTS, and tell 32 sp's to do physics and the rest on gfx.

    still, in terms of raw computational power, how does the aeiga physx card stack up against an 8 series card? is is as powerfull as a 8400gs?....a 8600gt?....more...? you get what i mean.

    Back when PhysX PPU came out, it really did stir up ATI and NVIdia, both then announced their own physics-on-GPU technology (eg: NVidia Quantum Physics that added one extra line to the G80 specs.) And there also was talk about people using three Radeon cards with two doing the graphics and one doing the physics, and that you could buy two X1900 cards along with one X1300 card to do the physics. Alas! all of that never got implemented but you can make out that a X1300 had enough juice for physics...which means a card as strong as a X1300 would do.....to put it coarsely, even 16 SPs could crunch physics well.

    so if i used my 8800GT for the gfx and 2x8600GT for physx i "should" be laughing? that'd be 64sp's over 2 cards, with 256 mb per 32 sp's, sounds like enough to me.

    No, the 8800 GT with its 112 SP's has enough juice for physics itself...even if just 16 SP's are doing physics.

    well since i have 3xPci-e slots and 2 spare 8600's i mayaswell use them for physics.

    I don't think it works that way. It's more like every video-card processes physics alongside graphics (Just like how the NVidia Quantum was supposed to work). ATI however took a different approach where in a Crossfire setup, one of the cards would be dedicated to physics computation.....but all that is no more.

    I have a 8800 GTS (G80), single, I'll still be able to use the PhysX API on my card.

    i wonder how much the preformance hit my geforce 8600 will take with the 2 games i have with physx support (which it city of heroes/villains and ut3).

    it is available to all CUDA enabled nvidia cards, which is every geforce 8 series card AND upwards.

    i've been reading up on CUDA stuff for months now, good to see them finally write physics for it.

    GeForce 9 implements CUDA, so it will be come with these drivers of course.
