quote: Maybe somebody else can expand on this, but it seems like physics cards should be able to work in conjuction with the new instancing feature of shader model 3.0, which according to Microsoft, "Allows many varied objects to be drawn with only a single command." As we've established, more physics means rendering more objects for the graphics card and therefore lower fps. But in some cases such as explosions, when you are dealing with a bunch of similar objects, couldn't instancing be used to draw the extra objects without slowing down performance much? Would this be left to game developers? Or could Ageia implement this in their API?
