Ahey,
At the risk of seriously hijacking the thread...
if you have a ppu you will have lower fps in game due to the nature of the thing. They are an awesome idea in principle but I still can't see them taking off. Hopefully nvidia can do somet useful with them. But we'd still need the game manufacturers to want to make games that make having one worthwhile in the first place
I agree with that on principle...
However, I'm reminded of the time when 3D accelerators started to come up. I remember a point in time where I actually scoured the shops for non-3D cards because, for some reason, the 3D engine reserved graphics memory and so I couldn't get the resolutions I wanted, and there weren't enough games to warrant 3D cards anyway, so why bother.
Grantedly, that was ten years ago, but still, if memory serves, there are one or two games out there
today that
require a PPU, so I believe it really is just a matter of time.
As for what's next: AI processor chips, smell emitters, 3D goggles with near-real-time motion response, you name it.
Cheers,
J.
