I'm not sure about vysync. I'll look that up and check it. I thought about the possibility of it being a debug build and I don't think that's it. In my bin directory I have osgviewer.exe at 25,600 bytes and osgviewerd.exe at 81,920 bytes. Both executables give me the same CPU pegging behavior (as observed by SysInternals Process Explorer).
My command line is "osgviewer.exe --window 100 100 200 200 cessna.osg". My video card is an ATI FireGL V7700 and the drivers are up to date. Ah- I just noticed something-- an error message: Windows Error #127: [Screen #0] ChooseMatchingPixelFormat() - wglChoosePixelFormatARB extension not found, trying GDI. Reason: The specified procedure could not be found. I'm running over remote desktop right now, so perhaps that's related. I don't recall seeing this error message before.
