BigDownload Article on Nvidia's 3D Vision Discover
I found a fun little bit of info this morning. They've now got an alternative to the $600 price tag of "3D" gaming. With the latest Windows Vista/7 GeForce drivers, you can activate the 3D Vision Discover option on any GeForce 8 or better card and then games should more or less work with the standard red/blue 3D glasses you can get at the movies.
Definitely not as high quality as the $600 method, but it's hard to argue with the price tag if you've got one of those cheapo 3D glasses lying around. Nvidia does have some custom 3D glasses that they've been bundling with some of their cards for this purpose and I don't know how much better they are, but the website above says you can use the regular ones ok. I don't know how cool it'll really be and it sounds like some games only really have partial support, but it would something fun and cheap to try.

Cool, but do most games out there have support, and is there a list of games I can check out?

i have some glasses laying around from Nightmare Before Christmas 3D that i forgot to return. but i'm on an ati card these days... :-(

Check this out, this might interest some of you.

This seems a lot more practical than ATI's multi-monitor card at least. I'm looking forward to trying this.

I tried that feature in Track Mania Nations Forever, which had that feature built-in, and I really didn't like the fact that all colors get effed up.

People let each other go to their houses like THAT?

Nope, I hate the red/blue method. I'd much rather do without 3D. NVidia's new shutter glasses look sweet though, but having to invest in a new monitor as well means that I won't be getting those for at least a few more years either.

From what I saw on their website, since the graphics card is doing the work, it should be able to give you 3D for any 3D game.
The possible potential for apparent complete compatibility with any 3D game means I will certainly be thinking of picking this up.

Yes, that's what I gathered as well. I'd like to try this on some GoGs myself to see how well this works. Supposedly, the game only needs to use Direct3D...
EDIT: btw, Nvidia does have a list of games that show how well each game works with that 3D vision here:

That's my understanding too, so I think you are right.

Beware folks, this stuff still in tinker territory. Forcing stereo 3D in games that aren't designed for it can be hit or miss. For instance, stuff like fps HUDs can end up looking like you're walking around in a stereo 3D environment with a piece of paper glued to your face.
I'd recommend researching the various options (Nvidia isn't the only one) and seeing equipment in person if at all possible, before making any purchases. IIRC, something like ~10% of people can't even see stereo.
[url=www.mtbs3d.com]Meant to Be Seen in 3D[/url] is a nice enthusiast site for stereo 3D gaming on Windows.
I got a low end pair of vr goggles a year and half ago. I want to love them, but they're pretty awful (poor design/ quality control). Still, the ability to finally see stereo is like upgrading to color tv. I promised myself that I'll never buy another monoscopic display again.

I've been doing this for a while now, and it convinced me to grab a 120hz monitor. Just need to buy the glasses.

You'd be surprised. Amazon has a whole network of people who bought Kindle, and with one forum post you can set a time, day and location to check out the owner's device.
