It seems to me she's now more friendly and considerate most of the time but still goes back to her old ways whenever Ryner happens to show higher laziness or absent-mindedness, or when the mood of the situation otherwise calls for it. Since I consider the violent and abusive state to be her natural one, I suppose she's keeping herself in check more than before, for his sake. Maybe she can even change. Who knows.
I didn't notice anything with DXVA.
