Hi Robert,<br>
<br>
I have done 1 week of testing now on the dramatic performance issue.<br>
As I said, when linking my program against osg 3.2.1 I get 60 fps <br>
and linking the program without any change against version 3.4.0 I
get 2.5 fps.<br>
Exporting my scene and running it in your viewer in 3.4.0 also has
60 fps.<br>
So the problem is somewhere in the settings of my software. :-(<br>
I used 2 different tools for profiling and both tell me that about
95% of the <br>
running time is done in nvoglv64.dll. One of the tool tells me it is
mainly the <br>
function "DrvPresentBuffers" but I'm not sure if this is reliable.<br>
<br>
I know it is actually not your duty giving help here but you are
very<br>
familiar with the driver calls and it would help a lot if you can
provide <br>
an idea what kind of setting might cause this issue.<br>
<br>
Many thanks in advance<br>
<br>

<div>Hi Werner,<br>
<br>
</div>
Hopefully others will be able to chip in as I don't have a
answer right now, it's certainly very odd. If it were a
general problem then we'd seen lots of issue with it being
reported. <br>
<br>
With this level of slow down it's almost like your'e
invoking a software renderer when running with 3.4.0.<br>
<br>
</div>
My next thought is that perhaps an OpenGL error is being
invoked somehow. Are there any errors being reported to the
console?<br>
<br>
</div>
What happens with the standard OSG example set? Does
osgviewer run any differently with models you have on the two
versions.<br>

<br>
I updated my project from version 3.2.1 to 3.4.0.<br>
I'm on Window 7 Pro.<br>
Unfortunately the frame rate dropped significantly from 60
fps to 2.x fps.<br>
I verified it several times by just linking to the 2
versions without any change of my code.<br>
Please see the 2 screen shots with the stats output.<br>
<br>
Do you have any idea what might be the reason for it or
how I can do further analysis?<br>
<br>
Thanks for any idea.<br>
