So I just got a new MBP, 15" 2.66 with dedicated 9600M. I've been using it mostly with the 9600M disabled just because I haven't had a need for any 3d graphics power yet. But I've noticed that the dock is kind of laggy in terms of animation. The most noticeable thing is when I open the Applications stack, the opening animation is rather choppy, not perfectly smooth. When I close the stack its fine, but opening it seems to choke a little bit. Is the 9400 REALLY that bad that it can't animate the dock fluidly, or is something else to blame? I tried resetting PRAM already but it did nothing. Any suggestions?
