That means if the triangles are big then pretty few to do with CPU. If you have display lists and much vertex data, then a TCL might give you big advantage. For texturing its advantagoues if the hardware is driven to do multitexturing. Performance optimisation is a rather individual subject. Some applications do never benefit from a particular optimisation. > This is something that intrigues me most for some time now.

If you want so see specific perfomance, you should try glperf. Thats one of the important feedbacks on your specific works.
