heh heh DealyDo, you are quite witty.

funny stuff.
anyway,
ktg:
""no special game version is required." I find that last part hard to believe."
dont find it too hard to believe.. it's true. what you need to realize is that the card itself is basically one big 3d image generator, and all of the current games that use "3d" graphics are implementing objects and environments that all can potentially be put into true 3d by this alternating image/3dglasses/doublevision monitor thing. what you WONT get is 3d when you're web browsing, word processing, viewing slideshows, or anything else that doesn't pass through your 3d card's 3d processor unit.
yes, it's true that it cuts the perceived frame rate in half, because of the reason you noted. but also, it's not just perceived, the -true- frame rate is cut in half because the graphics card now has to generate two sets of images, one for each eye.
like many, i am also wondering if it possible to use these with non-elsa cards. i dont see why not, since i doubt any portion of the 3d glasses setup is implemented with special hardware, but there's the issue of ELSA being willing to make drivers compatible with non-elsa cards (which i dont think would be too hard to do, but hey, they're out to make money, not make people happy).
i tried a pair of these things on at PCExpo a couple months ago, and they work as intended, and you do get a real 3d effect, but it's not as drastic as you might hope for. everything looks pretty much 3-dimensional, and you have a pretty good sense of depth perception with these, but dont expect to trip over yourself from things flying at your head or anything.
