ATM neither 1 nor 2 have support for multisample FBO. I've found this thread <http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=233432&fpart=1> on the OpenGL forums. In summary the main problem with multisample FBO is that it only writes to a render buffer, not a texture buffer and an additional copy is necessary to make the data available as a texture. > You could copy the FBOViewport-files into your app, rename it to > FBOViewport2 and modify accordingly.

However, I don't know what your constraints are wrt to the version you use?
