Hi, I am trying to figure out how to keep multiple graphics contexts in frame sync.
My operating system is Windows XP SP3. My graphics is NVidia Quadro NVS 290 with the latest driver 276.42. I'm using OpenSceneGraph 3.0.1 compiled with Visual C++ 2005 for win32. I have vsync on in the driver and in Traits, also I am using a CullDrawThreadPerContext as the threading model. I have 2 graphics windows with separate contexts showing the same scene with a "left" and "right" view on one display. I have the scene moving across both windows so that I can see if its properly syncing. It sometimes visibly looks to be a number of frames out of sync (i.e. one of the rendered context is dragging behind). What could be causing this? In the threads? Or down in the graphics card? Is there any specific settings I should set to make the rendered contexts stay in frame sync?
