most probably CPU limited. I'm not sure, but maybe a profiler could give you
some useful information (if OpenGL symbols and call graph profiling are

Do you have any triangle counts for the particular scene? I assume
your system should be able to render >50 Mio. multi-textured triangles
per second.
