Thanks a lot for your quick answer.

Just to resume : swapBuffer command may block at execution time (mean : when it appears to be on the bottom of the FIFO), or may not, depending on the driver implementation.
In any case, my java call shouldn't be blocking.
That makes sense.

Concerning  update/display frenquencies, I agree with you : I've no interest in having an update frequency higher than my vertical refresh.
That's why I 'm trying to understand how all the update/vsync/display mechanism works.
Today, with a simple Animator and with VSync activated, I get 60fps on a 60Hz screen (wahoo !), but the 'display' event is called about 100 times per second on my renderer. It's just a waste  of ressources I would like to avoid.


*Edit : some BIG mistakes. Sorry for my crap english and for the remaining ones.
