[Chimera-users] Nvidia 3D Vision

I got 3D vision working in windows with Quadro driver 191.87 and the most
recent 3D vision driver. To enable stereo for Chimera, open the Nvidia
control panel, choose "Manage 3D settings", then make the following changes:

Stereo-Display mode: Generic Active Stereo (With NVIDIA IR-emitter)*
Stereo -Enable: On

*note: if your card has an on-board DIN connector, you would choose that
option with the NVIDIA IR emitter instead. You don't see any flickering with
the DIN connector. With a usb connection only, you'll see occasional

As far as I can tell, the settings for 3D vision in games (the consumer
settings) are not compatible with the settings for professional 3D
applications like Chimera. In other words, if you enable 3D vision through
the link in your Nvidia programs folder, you are enabling it for games, not
for Chimera. For Chimera, use the method above.

Finally, make sure you have only one monitor enabled and that the monitor
refresh rate is 120Hz. I run two monitors normally, and if I want to use
chimera and 3Dvision I usually have to disable my non-3D LCD monitor and
then reboot the system.
