Guild Wars 2

I have 3D vision working and the button isn’t greyed out for me, are you sure that stereoscopic 3D is enabled in the nvidia control panel? New driver updates cause the stereoscopic 3D to turn off and requires you to run the setup wizard again to enable it. Also try setting the display to be in “Always” 3D mode in the nvidia control panel, some games have issues if not set to that..

Also I really hope that GuildWars 2 gets that official 3D support soon, this game already looks incredible in 3D and if the last few issues (shadows, land shadows with high convergence values, some skill effects, map) are fixed, than this game will become one of the best 3D experiences out there.

With Shadows on high and reflections set to terrain and sky only, using 3D I am able to maintain 60fps while exploring outside, 45-50 in dragon fights, 30-60 in WvW, and 35-60 in towns. What I find very odd is that enabling stereoscopic 3D actually increases my average fps, when 3D is off, I can pull off 120fps outside but in large fights or towns the fps bounces around from 25 to 50.

What I do know for certain is that overclocking my i7 3930k to 4.82GHz made a significant difference, even if I just jump back and fourth from 4.0GHz to 4.82GHz there is a night and day difference of 10 fps avg increase.

Try the new 310.33 driver from nvidia, it is a beta driver right now but it has increased my GW2 fps and might help you with your issue.
