I noticed today that even just with safari open my rMBP always runs on the NVIDIA not on the intel chip. My energy settings are set to automatically switch, anyone else noticed this?

There are people elsewhere in this forum who are deleting their AppleGraphicsPowerManagement.kext file so that they can force exclusive use of the Nvidia GPU at maximum clock frequency and have your problem. I think that's funny.

Have you tried repairing permissions and rebooting?
 
Just use gfxCardStatus and switch it to the integrated GPU. You will never notice an advantage from the discrete GPU, unless, allegedly, you play computer games.

Or, use gfxCardStatus to tell you which app is forcing your rMBP to use the NVidia chip. Look at the "dependencies" section in the gfxCardStatus menu.
 
install gfxCardStatus then click on the application icon at the top bar. it's an 'n' if its on the nvidia card. look at what's listed under dependencies, that's the program thats keeping it on the nvidia card.
 
The drivers are written by Apple, not nVidia.

I very very much doubt that. But they obviously won't be the same drivers, due to not using the same driver interfaces. But, the drivers are only supplied by apple as part of OS updates, so from end users perspective this would seem to be the case.
