    Default I love physics.

    It's called PhysX.
    Been waiting for that for over a year now.

    Err... wouldn't this be like a second FPU?
    I understand that its specialized, but it doesn't sound like nothing more than another place to send the math-coprocessor instructions to me.

    But, if it is another (cheaper) solution to getting another processor or another core, then I'm all for it. It would be nice to add another thing to the list for cheap upgrades to go with ram.

    With many computers now going dual core I really donít see a point in having a dedicated phy. processor. If you wanted nice phy you could just run it on the second core. And I doubt this chip would be much cheaper that geting a dual core processor.
    As a child, a library card takes you to exotic, faraway places. When you\'re grown up, a credit card does it.

    A physics processor is far better at processing physics than a normal processor. Think of it as a GPU, but for physics.

    I really donít see how it would be that much better, even if itís not as efficient as a PPU a second core would still be much faster. Also having the card would mean better cosmetic effects such as waterfalls and lots pebbles rolling around, but nothing that would effect game play simply because unlike graphics you cant scale down physics - if a ball roll off the shelf the computer still has to simulate it weather it is being drawn on the screen or not. So a game maker katering to people without the card would still have to some sort of physics in place that dosn't realy on a Phy. card.

    Uhh, you can tone done physics effects. Play F.E.A.R. and you will see how it changes.

    I know you can tone down phy effects, but you cant tone down ones that alter the gameplay in any major way.

    I can't wait to see these things commonly used.
    Dear cousin choppitychop89, you were a good relative, though I hardly knew ye.

    So what handles physics at this point in time? The GPU, or the CPU (math-coprocessor)?

    The CPU, although the new Havok physics engine will use the GPU to process physics.

    Right now, it's a Havok vs Ageia war.
