One of my applications (I have access to the source) can display a
bunch of triangles in wireframe and solid mode. Whenever I use the
solid mode, it is clear that the hardware acceleration is
working. However, as soon as I switch on wireframe, then the response
is much slower, leading me to believe that the software renderer kicks
in, which is undesirable (since it is rather slow).
Not calling glLineWidth () seems to make a little difference, but
displaying without lines is much, much faster. So my question is:
does anyone know how to get hardware acceleration for line drawing?
FWIW, I'm using XFree 4.1.0
