According to gfxCardStatus, Calendar is forcing the use of the discrete GPU (NVIDIA 330M in my case). Is anyone else running gfxCardStatus seeing this dependency? I like to keep my Mail and Calendar apps open in their own spaces and I would hate to have to constantly run on the discrete GPU because of this.

I'm getting the same problem–Dropbox, Little Snitch are doing this as well–ever since I upgraded to 10.8.3.
This is ridiculous, my battery life is more than halved by a single OS update from around 5 hours on a full charge to 2 at the max
Which system do you have? That's interesting that you're experiencing this same issue now after 3 released OS updates and not before like I was. Mine eventually stopped doing it, but then the screen took a dump. Now I have a rMBP and I'm not going to upgrade to 10.8.3 until I'm sure this isn't gonna cause it to run the discrete graphics all day long.
Woah, didn't realize the date on your post. Hah.
I've a MBP 6,2 (15" mid 2010) model. There's another thread on here talking about these 10.8.3 problems, and from what I've heard the rMBP hasn't been having these problems.
***** for those of us with older laptops, Apple seems to have problems with keeping older hardware running well with new software...
Mountain Lion: Calendar needs discrete GPU?
