I'm having severe performance troubles when I'm using the laptop's built in screen as opposed to an external display.
Whenever I stop using the external display, many of the OSX animations become slow and choppy.
I suspect what's happening is that my external display always uses the discrete graphics card for acceleration. I also sometimes work quite close to the limit of my physical RAM. This probably makes it hard for my integrated graphics card to work efficiently.
Any suggestions on how to force this machine to use the discrete graphics card EVEN when not using an external monitor?
