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 available). 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. bye, Manuel _______________________________________________ Flightgear-devel mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
