Hi everyone, Ok, I just picked up a 2.66 15" MBP with the 9600M GT and 4GB RAM today. When using Expose with only two windows (one Safari, one Finder), it is choppy/sluggish (low frames per second). This should not happen. It should be buttery smooth. - if i add one more Finder window, still sluggish - if I add yet another Finder window, still sluggish - once I have 6 Finder windows (plus the original Safari window), Expose is buttery smooth!!! -I also notice Expose becomes buttery smooth when loading some app or file. In other words, graphics performance improves when the machine is busy. What in the world is going on? Does anyone else experience this, or do I have a faulty notebook? FYI, everything is updated through Software Update. Any help would be appreciated. Thanks!
