Default Re: VSYNC Frame Counter

WOW!! Thanks for the help.. One short response pointed me in the right direction after many months (off and on) of looking at this.

I set Option "OnDemandVBlankInterrupts" "false" in my /etc/X11/xorg.conf file and now it appears glXWaitVideoSyncSGI() is now working correctly. I didn't have an OnDemandVBlankInterrupts option previously.

But I'm a little confused. The README file says OnDemandVBlankInterrupts is off by default. So why do I need to set it to false explicitly?
