<font size="-1">Hi,<br>
<br>
<br>
i have a problem which is there in all RCs (1-4) of current
ParaView: if i compile the RenderingBackend to "OpenGL2" and use
SurfaceLic the visualization time goes up from a few seconds (with
"OpenGL") to many minutes and the memory consumption from a few
GByte to approx 100 GByte. Switching back to OpenGL any thing is
fine. Without SurfaceLIC the OpenGL2 works although fine for me.<br>
<br>
Has any one tested OpenGL2 with SurfaceLIC-Plugin the last time
and has (the same) problems?<br>
<br>
o Kernel 4.7.6-1</font><font size="-1"><font size="-1"> / x86-64<br>
o Quadro 4000 <br>
o NVidia driver v367.57<br>
o PV 5.2.0 RC1 - RC4<br>
<br>
Best regards,<br>
<br>
Stefan </font></font><br>
