Viewport anty aliasing bug?

okey guys so this topic is back onnn.

The viewport anty aliasing is i think fcked up one more time. this time on 2.7 and 2.71 test builds. it was working on 2.69 without a problem. i have nvidia 610M can other people confirm that this is just me or the 6xx series support is droped down or what the hell happened that this is not working.
