[Chimera-users] stereo

Fri Nov 3 11:38:51 PST 2006

Thanks, now it seems to work. The original problem was that I did not 
find to find the stereo settings in the Nvdia 91.36 driver menu. After 
finding/setting them the  stereo option now  is working in Chimera.
Now another question: is there any particular 3D glasses recommended ?

Thanks

Hernando
