Paraview 5.7 Crystal Eyes can not work. I use command line “paraview --stereo --stereo-type=“Crystal Eyes””, however, it seems this mode can not work.

Afaik, Geforce GTX970 does not have Quad Buffer and do not support Crystal Eyes stereo.

I know that it use to be possible to emulate stereo rendering with Geforce card on windows, but this was dropped with nvidia driver 319.

I’ve never try to use this with ParaView Crystal Eyes though, not sure if this is supposed to work or not.

Have you been able to make this work with older version of ParaView ? 5.2 would be a good candidate.
