thanks for trying that out...
looking at the picture you attached, the antialiasing is surprisingly crude. in the region of that picture that i have attached its clear that pixel intensity calculations are not determined exactly by the proportion of each pixel that is covered by the yellow shape. if it were, we would see a lot more than just 3 colours being used and the edge would not appear jagged at all on a well calibrated monitor.
Do other nvidia card owners get similarly bad antialiasing?
I have tried various ATI cards and found they all implement precise antialiasing - even the cheap cards.
Thanks a lot
