Looking at the list, I noticed a couple of odd things. Why don't the ATI drivers support GL_{ARB,EXT,NV}_texture_rectange or GL_{ARB,EXT}_blend_equation_separate?
ATI sometimes makes strage decicions about the features their drivers support: Even though the r200 could support GL_ARB_vertex_shader just as the r300 does, they only expose GL_ARB_vertex_program.
Beyond that, there are basically 5 groups of useful extensions that they have but we don't:
- GL_ARB_texture_env_crossbar - GL_ARB_occlusion_query and similar extensions. - GL_ARB_point_parameters (I thought support was added for this?) - GL_EXT_multi_draw_arrays - GL_EXT_fog_coord
I once tried simply enabling GL_EXT_multi_draw_arrays, but there was a problem: When calling glMultiDrawElementsEXT while creating a display list the r200 driver called a Mesa function which wasn't to be called when creating display lists.
