See Cover Flow framerate

I stumbled on this useless but curious "defaults write" trick for the Finder that displays the frame rate when you flip through files in Cover Flow. I've only tested it in Mountain Lion.

The following will show the cover flow frame rate (as frames per second) within the Finder alongside each filename when flipping through files. On my system I get around 58 FPS consistently; try and beat that! I'm interested to see how retina MacBook Pros do, and, as such, this could be a useful if non-scientific benchmarking trick:

defaults write com.apple.finder IKImageFlowShowFrameRate 1;killall Finder

To get rid of it:

defaults delete com.apple.finder IKImageFlowShowFrameRate;killall Finder

[kirkmc adds: I, too, get 58 fps on my Mac mini, the same on my retina MacBook Pro. (Actually, it looks like it peaks at 58.87.) This suggests that there's something in the system that is limiting it, or that it simply can't go any faster.

I'll agree with the terms "useless but curious," but I'm sure someone will find something interesting to do with it.]
