I have a silly question.
In my country, the glasses they give us to see 3D movies, namely Avatar, don't work with batteries I think. They don't "flash" in my eyes. Just regular futuristic glasses.
Why do those Nvidia glasses work on batteries?
I know one thing is movies, and another is game's with frame rate drops. But still. I don't get it why the 3D cinema glasses "don't work"(?) for 3D computer games.
