--- Comment #1 from Roderick Colenbrander thunderbird2k@gmail.com 2010-03-21 17:05:01 --- These extensions were not offered on these cards in GL mode (see http://ati.amd.com/developer/atiopengl.pdf). I don't know much about this area of wined3d, so can't help. It might be that they used software emulation or used some GPU features which are not exposed through OpenGL.
