How to switch graphic card Macbook Pro
I just bought my new Macbook Pro Retina Today.
And already updated to the latest OS, but how do I switch to my NVIDIA GeForce GT 650M, I think I am using the Intel HD graphics right now.
I tried to google it already, but it seems that I have other options at my Energy option screen, as it only says 'Automatic detect Graphic option'. (I am Dutch so I tried to translate it)
Games like Runescape are laggy right now, any idea's on how to change?
Thank you in advance!
MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)
