Hi !

"I save the picture at 100"... could it be a JPEG compression setting of 100 % ?

I can see a little bit of pixelisation on the edge of the character. It looks like a "Final" rendering quality. If you want to remove this "stair effect" try a higher anti-aliasing.

On the picture above you can see the different rendering quality settings in VUE : preview, final, broadcast, ultra and best (a "user" quality with the highest anti-aliasing available). Look at the shadows, you'll notice aliasing in "preview" and "final" quality.

For a "perfect" render you should use "broacast" or "ultra" quality.
