I recently upgraded my unibody MacBook (Late 2008) to Lion and so far, am loving the experience. One gripe I have with the OS, however, is the subpar graphics performance I receive on my machine. The animations associated with Mission Control and especially Launchpad frequently stutter and are not as smooth as I would like them to be. Now, I understand that my machine is almost three years old, but I feel as though my GPU (Nvidia GeForce 9400M) should be able to handle simple OS animations. I have gleaned from elsewhere that the drivers for my particular graphics card may not have been properly optimized for Lion. Do you think that this might be the case or that my graphics card is just too old?
