Yada

Sorry, I'm just not seeing what you evidently are. There are very tiny anomalies in the right eye (as you're looking at the face) that are simply part of how it was animated I would guess. I don't see anything approaching a traditional stair step, which is what I think you're talking about. There was nothing different about these screenshots from the thousands of others I've taken through the years. Traditional stair stepping is going to occur everywhere on curved lines, not just a millimeter here or there.

Where are you seeing stair-stepping (if that's what you mean)? I don't see any.
