no antialising in opengl on macbook pro with amd 6750m in bootcamped windows 7

hi,

i am having a problem with not working anti-aliasing.
i am using opengl-mode in processing 2.0b8 on a macbookpro with amd hd 6750m as graphics card. i am using windows 7 via bootcamp. this laptop also has an integrated graphics card which should never be active under windows. could it be possible that processing is using this inferior card for some reason?

i checked the forum but to no result.

this following testcode delivers me a sphere with no anti-aliasing.
any help greatly appreciated.

public void setup() {
  size(1024, 768, OPENGL);
  smooth(4);
}

public void draw(){
  lights();
  translate(width/2, height/2);
  fill(100);
  noStroke();
  sphere(100);
}
