I didn't know that nvidia had workstation and consumer version of their
drivers. In any case the only 91.36 version that I found was at
If I install this driver I don't see any stereo setting when I get to
the video driver setting menu. Chimera stereo doesn't work either.
In the NVIDIA web site there is a consumer stereo driver at:
The web site says that it requires 91.31 ForceWare Graphics drivers to run.
I have tried the following permutations so far and I always get an error
message when trying to go in stereo mode with chimera.
1 - NVIDIA driver for Quadro4 downloaded from DELL support web site.
(driver version?. date 2004)). This one seems to have native stereo
support (at least it has a menu saying so).
2 - NVIDIA ForceWare driver 91.36 & Consumer stereo driver 91.31.
3 - NVIDIA ForceWare driver 91.31 & Consumer stereo driver 91.31.
With options 2 and 3 there are is a test option in the driver menu. This
test seem to run OK (i.e. I can see the two stereo images in a scene
alternating rapidly). Yet chimera gives an error message when I tried
the stereo mode (or calling the program with chimera --stereo).
Maybe none of the above are the correct drivers ?. Maybe I need to
reinstall chimera after installing the drivers ?.
