I ordered a few sets of basic blue / red 3D glasses, and they arrived today, so I turned on the 3D Nvidia setting, and voila, 3d.
Now then, I don't know if it's down to anything in particular, but my screen is only 60hz to my knowledge even if my pc is all very high end, so I'm presuming if your card allows 3d, then you can do it too.
Bat man works in 3d, but quite dark with the glasses on, so might have to adjust the settings.
I tried to download a few 3d films, but not getting any success so far, so perhaps different things need different hardware / settings / glasses etc.
Glasses only cost me £1.99 including delivery, but are the black frame ones, so a good deal.
Any advice regarding trying to get the films to work would be welcome.
