I don't know if they call it something different in Windows land, but it is a 
setting for OpenGL. I may be incorrect on the technical details, but if I 
remember correctly, the display is cut up into tiles. There is a display 
buffer, and an offscreen buffer and the tiles from the two buffers get 
swapped as needed.

I'm not really sure how the quad buffer works (my nvidia card is quite old) 
but if Blender works ok when you have it turned off, there probably won't be 
a way to have it on while using blender. Games generally use a pretty limited 
subset of what is offered by OpenGL, so there are cool tricks to get better 
performance in games that can screw other OpenGL apps up. (Hence the option 
to turn it on or off)
