Hi All,
Some users are complaining that my application (MacHg) is causing their MacBooks to switch from using the integrated Intel (lower power) card to the NVIDIA (higher power) graphics card.
Eg some related articles I dug up:
http://appletoolbox.com/2010/05/macbook-pro-mid-2010-graphics-switching-which-apps-trigger-how-to-monitor/
http://www.cocoabuilder.com/archive/cocoa/293116-i5-i7-auto-graphics-switching.html
http://support.apple.com/kb/HT3207
However, my application doesn't appear on the surface to make heavy use of graphics. (It does make heavy use of GCD though). Is there a general cause for this switching of the graphics card?. How can I find out when such a switch occurs in my code and for what reasons? Is there some technical article which explains the details of what's going on here?
Thanks!
