One some Macs, namely MacBooks, we are seeing very erratic frame rates. This appears to be because of the settings in AppleGraphicsPowerManagement.kext. Disabling it as outline here http://www.youtube.com/watch?v=gmoWoeNrkOs and the apps run at a constant frame rate.

Is there a programmatic way to fix this? We have a native OpenGL app but the same content can also be run in WebGL and Chrome/Firefox don't seem to exhibit the same choppiness.
