I'm in the game industry, and at my last job I had an opportunity to see a prototype of the physics cards by... who was it... aegis or something like that? Anyway, they're trying to invent a new card for people to buy for their PCs. At its core is a dedicated chip that does just physics calculations. This is a big win from a theoretical standpoint as it takes some of the load off the CPU. What it would mean for them to break ground with this new card is for game companies to program games with their card in mind. Several games have been / are being developed with the new physics card in mind. I know city of villains is among them.
I am a little skeptical of it. It would be putting more pressure on the PC buyer, and puts a little too much pressure on game developers. If I'm trying to make a cross-platform game for XBOX360, PC, and maybe playstation 3, it's tough for me to target that physics chip since the consoles don't have it. So that kinda limits game develops to developing for just the PC if they want to take advantage. And sadly, we live in a world where console games are the significant majority of the game market.
