Yes, you should worry about that swrast error, because that means Mesa's
libGL is being loaded into the OpenGL application, not nVidia's. Look
under /usr/lib64 and make sure libGL.so.1 is pointing to libGL.so.1.0.0,
which it should be if the nVidia drivers are properly installed. Also,
use /opt/VirtualGL/bin/glxspheres64 as a test, not GLXgears. GLXgears
is not a useful benchmark. Also, GLXspheres will display the OpenGL
renderer, which you can use to verify whether the nVidia drivers are
working properly.
