Niels,

You did not mention on which platform you noticed the speed difference between
OpenGL and IRISGL.
All our newer hardware, from Impact and Infinite Reality onwards, is based on
OpenGL, and IRISGL runs through software emulation (IGLOO), which gives OpenGL
a tremendous performance advantage.

Furthermore, support for IRISGL will cease to be in upcoming versions of
Performer.

Regards,

Dick.
