Can I force GPU rendering on my MBP when connected to a power source?

Solution 1:

gfxCardStatus (free)

I found the link to it on EveryMac along with some other info about graphics switching.

  • fast access via menu icon
  • auto/manually switch between discrete and integrated graphics
  • power source-based switching
  • growl support
  • open source
