This is good news. It was time to take advantage of multicore CPU's
The OSG has been able to be multiprocessing, but only for database paging and running multiple screens. Its nice to make it possible to utilise the cores for single screen set up - something that is much more common than muli-screen setups. I am hoping that we'll see two benefits - 1) better peformance, 2) low power usage, as 2 cores working at 40% is better than 1 core working at 80%.

I wanted to test it with our large size city and highway databases because they are seem to be CPU limited. Unfortunately it didn't work. I tried with cow.osg and result is the same. 'osgviewerproducer cow.osg' works without problem and osgviewer itself used to work before I updated from CVS so I guess it is related to the new changes.
At what point did you do a cvs update? This morning I checked in some improvements. BTW, by default the viewer should run thread per context, and fallback to single threaded on one screen systems, the new thread per camera threading isn't on by default. To switch on the thread per context you need to press 'm' in osgviewer to get it switch to the new threading model. BTW, is there any chance I could get access to your big town model for testing purposes :-) Robert. _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
