Hi, Correct me if I'm wrong, it looks like EXT_draw_buffers2 (OpenGL 3.0) is not enabled on Radeon HD2900 (R600 codename) due to hardware limitation. I have no R600 card to check glxinfo.
David Airlie enabled this extension with this commit: http://cgit.freedesktop.org/mesa/mesa/commit/?id=de48199693484fc903627ce53b007901af2e37a8 And current code is still: /* Supported except the original R600. */ case PIPE_CAP_INDEP_BLEND_ENABLE: case PIPE_CAP_INDEP_BLEND_FUNC: /* R600 doesn't support per-MRT blends */ return family == CHIP_R600 ? 0 : 1; Regards.
