Rendering 3D

[FreakWave]

I want to render battlefield 3 in 3D when i get my 3D monitor. My graphics card can play Battlefield in high. If i do render battlefield in high, would that mean i would have to change to medium graphics? help me im confused or do 3D monitors just duplicate the picture for you?

Generally, rendering a game in 3D will halve your frame rate because it must render the view for one eye, then the other.
