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

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