Hi Ken. Which OpenGL verison does paraview need? Also, by saying OpenGL drivers, do you mean the GLX version of the supercomputer? Coz my paraview server is running on a linux machine. The version of GLX on the machine is 1.2. The latest GLX version is 1.4. Do I need to update the glx to 1.4? Thanks!
