One could potentially implement a C++ 11 theading as an OpenThreads implementation that sits alongside the current pthreads/win32 threads implementations, but practically this won't provide much benefit as all C++ 11 threads currently does is provided a portable API that is implementation with platform specific threading libraries much in the same way that OpenThreads does right now. The benefit from eventually moving to C++ 11 threads would be simplifying the OSG code base via the removal of OpenThreads, but speed and functionality wise I wouldn't expect to see any difference. If I were to write a new scene graph today then I'd use C++ threads, but for the OSG as it stands there isn't yet a strong reason to port over in the near term. Robert.
