--- Comment #32 from Stefan Dösinger stefandoesinger@gmx.at 2009-01-17 19:12:19 --- fyi, I have some patches in the works that duplicate the vertex shader in case of a format switch. That way it should work for cards/drivers that don't have the mentioned extension too(at the cost of slightly more memory use, although that shouldn't be measurable)
