As far as I know you don't need any kind of specific card or driver. If you have a series 8 Geforce and a rescent set of driver you should be ok to do it.
And for activating it you have to go to the control panel in the "set up stereoscopic 3d" (look at the pics I've attached)
By the way, sorry for taking so long to answer, I don't come by here very often
And for those who can't activate it or doesn't meet minimum spec, I've included 2 screenshot of what it look like with LFS. This should give you a good idea.
the 3d drivers for ati cards, well, there is no red blue, it just separates everything, but i only have 3d glasses, the red and blue ones, how can i get those to make everything 3d
It is there, it's the option "Enable Stereo"
You can choose "Enable stero by hotkey" later after you get it working so you can turn it off and on when you like. For now, force it to Enable make sure it's always on.
Just use Red/Cyan. If you manage to get it working, then test it with Optimised red/cyan later. Depends on your monitor if that will work better or not.
Then when you start your games you will see this..
Press "n" a couple of times and then this..
Then get into the game on track and go through the rest of the setup sequence with the iZ3D overlay in game. You have to adjust convergence for short range and long range. When the setup is completed the screen will go much brighter. To switch the overlay off press "Shift" and "Numpad *"
You want something similar to this..
edit: tested and works with ATi HD4890
edit: AA seems to turn off automatically.
