<font size="-1">Hi,<br>
<br>
<br>
i have a bigger case (20e6 points) - there i found the time from
clicking for e.g. rotation till showing the coarse view (LOD) is
nearly the same, however from the coarse view back to the detailed
one pv 3.9.0 is about factor of 2-4 slower compared to pv 3.8.1.<br>
<br>
My settings of the LOD are:<br>
<br>
LOD Threshold (on), 0 MB<br>
LOD Resolution (160x160x160)<br>
Outline Threshold: 0 MCells<br>
LockInteractive Render 0<br>
Allow Rendering Interrupts: off<br>
<br>
Output of Timer Log:<br>
<br>
3.9.0:<br>

<font size="-1">What are the changes between 3.9.0 and 3.8.1
regarding the LOD? Seems, 3.9.0 is not using OpenGL? I have used
the same complier-settings for both versions.<br>
<br>
If checked the effect with smaller cases - there the effect is
smaller.<br>
<br>
Best regards,<br>
<br>
