Hi Vinoth, OpenGL doesn't support multi-threading within a single graphics context, so you are constrained to doing the rendering for each context in a single thread. The threading models that the OSG provides reflect this, enabling threading of the update, event and cull traversals in parallel with the draw thread. This is all possible with a Qt based viewer, but different versions of Qt add their own caveates/problems. If you care a about full screen real-time performance then Qt probably isn't the best tool to use, native osgViewer based viewer will work much better, but if you need the 2D GUI elements that Qt provides then you'll need to jump through the extra hoops that Qt throws into the mix.
