there will be enviornmental processing cards(for weather, water effects, and fire).
ehh that's pretty much what the PPU will handle combined with the GPU for drawing it...as far as the water moving, leaves on trees, fire, etc...it's all PPU
Personally I think within about 5 years it's gonna be one of those things like 'Jeez man, how did we play without this a few years ago?'
Yeah it is rather insane...yet another component to buy, however over time the price will probably drop, competitors might emerge, and last I saw they were gonna have a card with a slot on it so you could basically change out the actual PPU much like a processor...so who knows you could probably be able to buy a cheaper PPU from a selection muchlike CPU's currently.
Woah! Look at my physics card in action! When the player gets shot his legs bend FORWARD instead of backwards! And when he drops his gun, it drops accurately and even tumbles a few times! Here's 200 dollars!
Yeah, it's quite a bit more than that....someone linked videos to some demos that involved the PhysX card and they got some amazing stuff considering it's just pretty fast put together stuff for demos and not a full blown mega endorsed game.
The amount of things flying around on the screen would make a current system cry for mercy and the graphics aren't even great being that it's a demo.
