I have 3D Vision and I absolutely love it. For me, it's not so much about the images popping beyond the borders of the screen, but for turning your 21" wide, 12" tall monitor into a 21" wide, 12" tall, 24" deep diorama of your screen contents. I went back and replayed Portal, I'm replaying Left 4 Dead, and I've downloaded and played the BioShock demo from Steam (even though I've beat the first two BioShock games on PS3 already) just to get a feel for them in 3D. Burnout looked wicked good in 3D as well, but I haven't set up my G25 to really play it.
Yes, you do have to wear the glasses, but I've worn glasses 17 hours a day for the last 15 or so years of my life, so it's nothing huge to me to add another pair in front of them. And if you don't wear glasses, just think of them as a pair of computer sunglasses that you wear indoors. I do realize that there are people that cannot make use of the glasses, and unfortunately, I have no recommendation in such a case.
The effect of the glasses is the best quality I've experienced, better than the passive glasses they used for Cameron's Avatar and absolutely destroys the red and blue filtered glasses. The longest I've worn them, so far, is about 4 hours and I haven't had a problem with them yet. I've had people that game casually and people that game day and night try them, and everyone I've had try it loves the technology. One of my friends has vertigo, but was able to enjoy herself with the kit. Even one of my friends, who got a headache and felt dizzy/nauseous with the theater glasses, said he had no problem gaming with the nVidia kit.
So yeah, I can't wait to try FFXIV in 3D. And yes, I will be trying 3D Surround Vision if I get two more of those Alienware monitors setup in my new Apt.
