The game runs a lot smoother for me now. Or not. What I really have noticed is that there are absolutely no drops like when there are a lot of players, or in siege, or, on DTV, in certain rounds (like rohirrim), where my framerate just died. Now it's all fluid.
What I have also noticed is that I think framerate lowers sometimes, but the "fps meter" won't change. I might be wrong though, but sometimes it feels like fps drop a little and the meter remains at max.
