With "my renderer" u mean the GLEventListener ur animator calls ? If so ur display method on the GLEventListener method is only called 60 times per second when VSync is on (assuming the default 60hz LCD refresh) and ur Animator is set to "RunAsFastAsPossible". When u get 100 display calls per second theres something wrong with ur code.

Maybe u could provide some code snippets to clear things up ?

Also take a look at the JOGL demos e.g. "Gears" http://github.com/sgothel/jogl-demos/blob/master/src/demos/gears/Gears.java and try the simple demo on ur machine. I'm sure u will immediatly see that the display method is only called in sync with ur display refresh (60hz). If Gears has the correct display method call count and ur code does not u know that theres stg wrong with ur code.
