Antialiasing problems in OpenGL


Antialiasing doesn't work with lines on our ported F77/C/OpenGL application, at least not with the Geforce 2MX that came with our new G4-box. On Wintel, you can fiddle with driver settings to force the card to antialias or not. I find drivers for the card in /System/Library/Extensions but how can I change/see the settings? Maybe there is something very simple that I've missed or some Apple software engineers has to do some major rethinking.
