Hi Robert,
Thanks for your answer. But I still have some doubts here. When I load
the model with osgviewer, and press key 's', it displays that the
frame rate is only 34 fps. But in my application, the frame rate goes
up to 60, which is kind of strange because I have some control inside
the loop
Yes, I doubt that this is the refresh rate of the monitor, not the
real frame rate. How could I avoid the sync-to-vblank thing, so that
I can have the actual frame rate?
Thanks,
Dat

It *is* the actual frame rate. This is

frameRate = (double)numOfFrame/(endTime - startTime);
But it always gives me about 60fps. Did I make a mistake somehow?
(startTime and endTime are in seconds already)
60Hz sounds like you are running with sync-to-vblank.

Dear Robert,
Thank for your answer. One more question. Right now I have my code like this:
numOfFrame = 0;
startTime = time(NULL);
while (!viewer.done())
{
viewer.frame();
numOfFrame ++;
}
endTime = time(NULL);
frameRate = (double)numOfFrame/(endTime - startTime);
But it always gives me

Dear all,
Could you tell me a way to get the average frame rate after, for
example, 1 minute of running?
The OSG itself doesn't give you this but it gives you all the tools to
do it. You have an osg::Timer
