hardware stereoscopic setting (si 2015)

[forton]

Has anyone tried the hardware stereoscopic setting?
(preferences, display options, enable hardware stereo).

I get following error:
' WARNING : 3000 - "Enable Hardware Stereo" display preference is enabled but hardware stereo is not available because the graphics hardware is not compatible or not setup properly.

My stereo display works (nvidia 3D vision) so I guess it's properly setup.

Cheers, Wim
