Stefan, I am testing out 5.2.0 with offscreen rendering and have observed similar results. My version built with OpenGL2 is slightly faster than the OpenGL version for non surface LIC operations, but massively slower when using Surface LIC.
Comparing back to version 4.4.0, version 5.2.0 with OpenGL2 is faster for non-Surface LIC operations but much slower for surface LIC. In fact when using Surface LIC, version 4.4.0 is faster then 5.2.0 with OpenGL. My test case involves creating a slice in an unstructured dataset and sweeping this slice in one direction taking multiple snapshots. Hopefully someone more knowledgeable on this subject than me has some ideas on the problem and how to address it. -Andy On Tue, Nov 15, 2016 at 5:35 AM, Stefan Melber <[email protected]> wrote: > Hi, > > > 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.
