Disable OpenGL?.
Force it to render in software?

yes in software

When you specify the pixel format descriptor, enumerate PFD_GENERIC_FORMAT as one of the dwFlags. This should force the device context to use the MS implementation, as per MSDN online here: http://msdn.microsoft.com/library/psdk/opengl/ntopnglr_73jm.htm

Does that answer your question?
