Oh, yeah, thats true. The examples do require this functions to load the
shaders. It has changed since the last release. However the core library, do
not need that support from the side of osg.

Hmm, this is really strange. Are you sure, that you really got that speed. I
mean, maybe the counter just don't show exactly that FPS which is really
running. Try to make your own frame time computations. Just something like this:
int lasttime = time(NULL);
while (viewer.running())
{
int current = time(NULL);
int difference = current - lasttime;
printf("FPS %f\n", 1000.0 / float(difference));
lasttime = current;
viewer.frame();
}
This is just an example. Maybe you can then compute the real performance.
Because it is really strange - why using the StatsHandler one should got higher
performance than without it ;)
Best regards,
Art
