Hi,
Frame rate stuck at 60Hz usually means vertical sync is on.

Hi,
It's been a while since I tested rendering performance on my development
machine and now I'm experiencing something vaguely familiar and quite annoying.
Even with a very simple model, the statistics feature ('s') in the osgviewer
application (3.6.4) reports a draw process taking over 16ms so that the
rendering just barely makes it at 60Hz, see the attached screenshot. Sometimes
it drops down to a short draw after a while, for no apparent reason, but more
often it stays this long.
This makes me doubt any further performance investigations, now knowing whether
additional operations in a frame will make draw go over the 16.7ms limit or not.
I vaguely recognize this from way back but I can't remember the cause, and I
can't find anything about it in previous osg-users discussions. It feels like
it's waiting for buffer swapping or something, and I wouldn't be surprised if
it's something obvious that I should know. Maybe it's just the statistics
reporting incorrectly? Does anyone recognize this and do you have any
suggestions? It works on my older laptop but not on two of my desktop
computers. My config below:
Intel i7-4790K 4GHz
16 GB RAM
GeForce GTX 970 with latest 451.67 drivers
Win10 Home
OSG 3.6.4
Regards,
Andreas
