Hi Anders, To get down latency for the osg viewer to run single threaded - this will reduce the latency by a frame. Another thing you could do is use svn/trunk version of the OSG as this add a sync option that uses swap buffer sync that ensures the main loop doesn't get too far ahead of the swap buffers on the graphics card.
