IRender nXt does to anti aliasing. If you want to increase the amount of anti-aliasing, you can render at a higher resolution, and then resize and resample the image in a paint program to the desired resolution.

Here is a similar scene rendered for 10 passes, at full rendered resolution (600 pixels)

By zooming on the corner, you can see the anti-aliasing effects.
(Zooming in a paint program magnifies the effect of the anti-aliasing)

If you want to increase the anti-aliasing, you can render at 2X or 4X the resolution, (which will take 4 or 16 times longer), and then reduce and resample the image to the desired resolution. This will add additional anti-aliasing during the resampling process.

Here is the same scene rendered at 1,200 pixel resolution and then reduced to 600 pixels:

And here is a zoomed area on this image, to show the improved anti-aliasing:
