Thanks, Bob. This is a relief ;-). I don't have the acces to similar Vista setup yet. Will try to grab two boards and do the checks this week.Will post a meesage with results when I am done.
Thanks again.

I used code very similar to the osgcamera example, multipleWindowMultipleCameras method. Does anyone have experience setting up a 4-monitor (each 1440x900) system on Windows Vista? I have 2 osgcameras/contexts rendering left-half/right-half of the scene. With 2 Nvidia graphics cards both in dual-head mode, if I render each camera to a viewport 2880x900 I'm hoping that the scene will be spread properly over the 4 monitors (will try it shortly once I round up four HD monitors), without configuring the "extending the desktop" option in Windows, which seems to take considerable resources in the dwm.exe task ("dynamic window manager"), which appears to have an OSG rendering performance impact. Anyone have similar experience here, or other configuration suggestions? Thanks. Bob. -------------------------------------------------------------------------------------- Wojciech Lewandowski wrote: 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 have read your post and I see that you have exactly such setup. Does osgviewer outputs to monitors cards attached to both cards ? Cheers, Wojtek 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. Robert.

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 the appropriate traits->screenNum, or does it take more than that? Has anyone done this in Windows Vista? Thanks. Bob. -- Robert E. Balfour, Ph.D. Exec.
