Here is what I see:
I place the glxgears window outside of, but close to the Terminal.app 
window from which I started glxgears. The wheels are moving smoothly, 
and when the glxgears window has focus, I get a reported 3458 FPS. When 
I click on the Terminal.app window to give it focus, the visible 
movement of the wheels is exactly the same as before, but I get 59 FPS, 
that is, over fifty times slower! My conclusion: What you see in the 
window has absolutely nothing to do with the reported FPS, and the 
latter depends in an extreme way on the (geometrical) environment of the 
glxgears window.
