Do you mean that they can display a precomputed frame loop in real time? If so, that's what I said. If, on the other hand you mean that they can actually calculate and display a continuously changing 3D system, then I'm very surprised, because when I heard about it, I understood they couldn't. Have they been able to do it for a while, or is it the result of recent optimizations? >> Also, they were only able to manage horizontal parallax. > This is true.

Sounds like a very awesome system. I should be able to get one for my PC any day now, right? :-) > --> Michael B.
