Expected frame rates for a full-screen blur

Hi there,

On a MacBook Pro with OS X 10.9.2, does anyone have any estimates for
anticipated frame rates of a full-screen animated blur? I noticed that when
my window is not maximized, the blur is smooth and high frame-rate. When
maximized the blur is somewhat choppy. Unfortunately I have no clue how
much work is really involved in GPU blurring and whether I'm being
unreasonable to expect that many pixels to be blurred per second (this is
on a retina display).

Can anyone let me know if it's worth me trying to optimise this or whether
hardware limitations will mean that realistically I am expecting too much.
