Anonymous, don't think that everyone sees the world with the same eyes. Maybe you just didn't play enough to get used to 3D, maybe your eyes are not really that good you know??? Don't assume things just because you didn't like doesn't mean we all think like you.
I've been using 3D Vision for 3 straight years and I can't stand 2 gaming anymore. I now feel eye strain If I play in 2D, I mean, I get bored easily, just like you in 3D.
Anyway, I'm not a geek and I don't play 10 hours straight, I have a wife, work and I got to the gym, so I never play more than 2 or 3 hours consecutive.
No one should play 3D for more than 3 hours straight.... If you like to spend a day playing games, just do it in 2D.
Have a good one.....
