I was wrong, the nodes do not wait for the next frame. What is happening is the sending computer updates so much faster then all the nodes (2.1 GHz compared to 866 Mhz nodes) that it does almost all of the work. If I add any more load, more Poser objects or more complex sky settings then the nodes might not get to render anything before the source computer finished the frame. This is not a very efficient use of resources. Vue send one frame to each node and the last frame get's sent to all the nodes to finish. Dale
