Hi Bob,
Last summer when testing multiple GPU rendering I found that if I
forced the serialization of the draw dispatch I actually got better
performance. This suggest a performance problem in the driver, or it
could also have been a hardware contention. Either way even on my
quad core, dual

Hi
I have two Nvidia 8800 cards on a Windows Vista platform (HP), and
setting traits-screenNum to 0 or 1 as Robert indicated does send the
rendering to the appropriate graphics cards. I used code very similar
to the osgcamera example, multipleWindowMultipleCameras method.
Does anyone have
Hi Bob,
Using the screenNum set to 0 or 1 should select the appropriate card.
When you run osgviewer on your system it should open up two
windows/two slave cameras automatically, press 'f' to toggle off full
screen to see the actual windows.

Hi Bob,
Seems like you asked related question to mine. I would be very interested in
your results. I tried to run osgviewer on two graphics boards withour
success. But I was on XP and boards were different. I have not given up
completely, hoping that Vista or identical cards may work. Then I
I also have an HP Windows (Vista) box with 2 Nvidia graphics cards
(independent, not SLI-configured). In order to configure two
osg::cameras, each one rendering to its own specific Nvidia card, how do
you specify a camera graphics context for a specific graphics card. Is
it simply specifying
