Hi Robert,<br>
<br>
final analysis:<br>
<br>
In our software we did the following patch to make it run with high
fps in master of 3.4 branch:<br>
<br>
<span style=" color:#c0c0c0;"> </span>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" color:#c0c0c0;"> </span>osgNormals<span style=" color:#c0c0c0;"> </span>=<span style=" color:#c0c0c0;"> </span>new<span style=" color:#c0c0c0;"> </span>osg::Vec3Array;</pre>
<tt> </tt>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">+<span style=" color:#c0c0c0;"> </span>osgNormals->setBinding(osg::Array::BIND_PER_VERTEX);</pre>
<tt> </tt>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" color:#c0c0c0;"> </span>geometry->setNormalArray(osgNormals.get());</pre>
<tt> </tt>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" color:#c0c0c0;"> </span>geometry->setNormalBinding(osg::Geometry::BIND_PER_VERTEX);</pre>
<tt> </tt>
<pre style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" color:#c0c0c0;"> </span></pre>
Obviously we have to set the binding in the array itself and the
setNormalBinding works but has poor performance.<br>
<br>
Now we are happy again :-)<br>

Hi Robert,<br>
<br>
the 3.4.0 tagged version is OK with the frame rate.<br>
We discovered your commit in the 3.4 branch causing the problem:<br>

<br>
The question is: Why is the viewer frame rate OK, even it is built
with the same version we are using?<br>
What are we doing different to the viewer?<br>
<br>
Thanks so much for your excellent work!<br>

<div>It's a long shot, but have your tried the OSG-3.4
branch or OSG master as these both contain a range of
bug fixes/OSG improvements, there is chance that
something has changed that might fix things. <br>
<br>
Whatever the cause is it seems to be some small OpenGL
state difference between OSG-3.2 and OSG-3.4.0, I'm
afraid I don't know what this might be. Perhaps using a
3rd party OpenGL debugging tool might help here -
capture all the GL calls for 3.2.x and 3.4.x and see
what the differences are.<br>
