nVidia GeForce 3D Vision Kit. Amazon customer's review. By K. Gish (California): I'll try to be brief, as to not simply reiterate too much of the other reviewers.
1) These nVidia glasses work very well, and the glasses have wider field of view than the eDimensions 3D glasses (which I bought 2 years ago). The 3D effect is fully adjustable in the two key dimensions: separation (amount of 3D effect) and convergence (how far away the objects appear). Having a 60 Hz refresh rate for each eye is critical; my eDimension glasses with an older 60 Hz LCD monitor could only give 30 Hz per eye and lots of flicker. I haven't tried the eDimension with the new 120 Hz monitor.
2) My computer set up is not excessive, but not wimpy either: AMD Athlon 64 X2 6000+ 3.0GHz; nVidia 8800GTS; 2 Gb DDR2-800 RAM; ViewSonic VX2265wm 120Hz LCD monitor; Windows 7 Home Premium 32-bit. This is about the bare minimum set up for good 3D.
3) Make sure you uninstall your current GeForce drivers before loading the new GeForce + 3D Vision drivers (collectively downloadable as the "Full Driver CD" from nVidia's website). I had mismatched drivers at first (from Windows 7), and got excessive ghosting and got the right-eye signal going to the left eye. Reinstalling with fresh drivers from nVidia solved the problem. Now I have no ghosting, no flicker, great 3D effect.
4) I've only tested one game so far, World of Warcraft, which looks beautiful. There's a setting in WoW to allow the cursor to adjust its depth to match the interacting object - nice! Takes 15-30 minutes to get used to, but then it's fantastic. Setting the convergence (or "screen depth") to a low value makes the objects appear far away and is easier on the eyes.
5) Caveats: (a) you need Windows Vista or 7; XP will not work. (b) There are only two LCD monitors at the moment that offer true 120 Hz refresh rates:
ViewSonic VX2265wm FuHzion 3D/120Hz LCD Display (Black) and
Samsung Syncmaster 2233RZ 22" 3D Gaming LCD Monito; many LCD TVs claim 120 Hz, but this is upscaled, and none currently take 120 Hz input; some DLP TVs will work - check nVidia's website.
