[MPlayer-users] Question about -vo gl

[Vladimir Mosgalin]

I don't understand one thing in gl output driver: both gl and gl2
drivers eat much more cpu resources in window mode than in fullscreen.
Why? Shouldn't it be other way around or, more likely, no difference?

Is it because opengl low-level driver works this way, or some extra code
is executed in mplayer for window mode? I'm using X.org 6.8.1 and fglrx
8.8.25 driver.
