Hi,<br>
<br>
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.<br>
<br>
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.<br>
<br>
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:<br>
<br>
Intel i7-4790K 4GHz<br>
16 GB RAM<br>
GeForce GTX 970 with latest 451.67 drivers<br>
Win10 Home<br>
OSG 3.6.4<br>
<br>
Regards,<br>
