Anti aliasing in 0.9.0 RC1

I do not see any difference using ofEnableSmoothing() or ofEnableAntiAliasing() on 0.9.0 RC1 but I do using 0.8.4. Is there something else that I am supposed to use instead in 090, or some other flag that needs to be set? Or is it not available or even broken?

Any pointers would be much appriceated,
Cheers
