OS X Lion is quite demanding for old Macs. Even though I own a 15'' MBP early 2011 with the 'powerful' Intel HD 3000 for integrated graphics, some animations just don't feel right (low fps).

This is especially very noticeable with Mission Control: It's choppy.

When ever discrete graphics are being used (e.g. QuickTime movie with GPU acceleration, Win7 in VirtualBox...) Mission Control is much smoother and easier on the eye.

Question:

  • Is it possible to force discrete graphics to be used when the MBP is connected to a power source?

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

    This program has helped many get better battery life, better performance and more importantly achieve a more stable system in the case where a specific program has issues (crashes) when the graphics card switches or is one mode over the other. A great tool to have in your toolbox if you like optimizing things. – bmike Feb 15 '12 at 13:53
