Are you experiencing subpar graphics performance using your macbook pro connected to the 30"? Particularly in Quartz Extreme animations. I have the 2.16ghz Macbook pro with the 256mb gpu and 2 gigs of ram. Exposé in particular gets a bit choppy when working on the 30". It was a big problem for me when I had my powerbook, but I thought the jump to 256mb video ram would solve the issue. I'm even considering selling the 30" and picking up a 24". I don't expect to play games or anything, but I'd at least like to see my OS be able to run smoothly without graphical hiccups. Any thoughts? Maybe running in closed-lid mode will solve this issue? I will probably try that when I get home from work. Might not sound like a big deal for most, but I am pretty anal about framerates and seeing the aqua interface drop in frames is rather annoying.
