Hi Robert, I did some brief testing on this. I had problems before with the CullThreadPerCameraDrawThreadPerContext model as it would lock up the viewer. All of the other models seemed to work fine, but when I switched to the CullThreadPerCameraDrawThreadPerContext model, it would lock up. I posted the problems about 2 months ago.
I tried the viewer both with the cow.osg and a txp database that I use and it didn't lock up with either file. Previously the viewer would lock up on both of these files. So, whatever you did definitely seems to have fixed the problem that I was having. Great job!!
