[Chimera-users] Stereo vision with Quadro 600

[Greg Couch]

Those settings should work for Chimera too.  Please download 
http://www.cgl.ucsf.edu/home/gregc/wglinfo.exe, run it in a terminal 
window (eg., All Programs / Accessories / Command Prompt), and send the 
results directly back to me.  wglinfo lists all of the possible OpenGL 
framebuffer configurations and should confirm if OpenGL is reporting 
that stereo is available and with which graphics capabilities.  I'll 
summarize what I find to chimera-users.
