Hi Robert,<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>
<br>
- Werner -<br>
