10.8.3 Forcing Discrete Graphics With Dropbox and others

I have a mid-2010 MacBook Pro, and under 10.8.2 most of my apps ran on the integrated graphics chipset.


Now with 10.8.3, apps including Dropbox, Transmit, Tweetbot, Growl, Reeder, and Bartender are forcing the usage of the discrete graphics card. There are a few more people on MacRumors noticing the same thing. The only one who posted what machine he had was also using a mid-2010 MBP.


I have tested on a brand new MacBook Pro Retina with 10.8.3, and those apps don't cause a switch to the discrete graphics card.


Is anyone else noticing apps forcing the discrete graphics mode in 10.8.3 that weren't in 10.8.2, and if so, what model of Mac are you using?

MacBook Pro, OS X Mountain Lion (10.8.3)

Good thing growl does not trigger it. As for Skype it is pretty normal and logic to trigger the nvidia card as it uses the isight camera

It's not that simple. Both FaceTime and Messages use the iSight, yet only Messages switches to the discrete GPU when you videochat.


A little birdy told me that Dictation now runs on the integrated GPU as well.
