If you are upgrading to a svn/trunk or dev release then you should be able to update the whole OSG and not worry about plugins - just pull them all in as well. Most of the plugins don't yet take advantage of the new changes of the Drawable subclassing from osg::Node, so they mostly all still create osg::Geode and attach the Drawables to it. These plugins could be optimized a little by removing the Geode where it isn't required but I haven't tackled this work. Others are welcome to pitch in. There are various other small tweaks to the OSG to help reduce the CPU overhead, so in general the the latest should just be all-round a better bet. Don't expect big performance changes though, it's just little improvements here and there. Robert.
