After seeing that I was unable to change 3D settings in the main menu (Even though I have a 3D compatible monitor), I searched for similar cases and noticed that all those who can alter the 3D setting from the main menu are using nVidia cards.

Is the 3D feature exclusive to nVidia cards? Anyway, any others with this issue? Would appreciate an official reply.

Ati cards doesn't natively support 3d as far as i know..so uh maybe if you download ati's third party 3d driver it will work
