Yes and no. first of all, looks like neither of us bothered to read the tooltip, lol, it plainly says that (at the moment I hope):

So no Override for us, do file a bug report though, use the 'buton' reason
Then I tested with Tesselation Normal:
4xAA: FPS: 26.8 / Scores: 674 / Min FPS: 18.9 / Max FPS: 54.4
FXAA: FPS: 30.2 / Scores: 762 / Min FPS: 20.8 / Max FPS: 62.7
Looks like the shaders get hammered on Tess Xtreme and FXAA suffers...
That's one thing, and the other, since I can't stand tearing and since nVidia set Vsync ON by default in the newer drivers I tend to forget about it so my old tests (and this one above) where done with Vsync ON, so turning Vsync OFF with Tesselation Xtreme got me this:
4xAA: FPS: 19.4 / Scores: 488 / Min FPS: 10.8 / Max FPS: 46.4
FXAA: FPS: 21.5 / Scores: 542 / Min FPS: 11.5 / Max FPS: 54.0
Maybe this needs testing with some other programs too, Michael said he has an AA comparison in the works so he'll cover it better, also I'm pretty sick of starring at looping demos daaammmit.
