Hi, Robert!
To see what happen, just run osganimationviewer with low FPS with patch and
without it.
*OSG_RUN_MAX_FRAME_RATE={2, 3 or 5} osganimationviewer* *--play-mode once*
some_model_with_rig.osgb
osganimationviewer's source with play-mode option in the attachment.
Without patch, the last rendered picture (with different FPS) can be not
the same.
With patch, rendered picture is always the same no matter of FPS.

Hi Konstantin,

After Animation's update method *return false*,

No cpu overhead, i think :)
I need to test this out to check what happens right now and with your
patch, and whether there is a CPU overhead.
What is the easiest way to recreate the problem you've seen? Modifying an
OSG example would probably be the most direct way.
Cheers,
Robert.
