if the opensource driver don't do what you want you only use the wrong "workstation" software!
well Maya,3dmax and Catia don't run well then its the fault from 3dmax and CATIA.
the people should just quit in using this shit and they should start using "Blender"
and yes "Blender" works well with the Open-source drivers.
and if "Blender" don't do the 3D CAD work then they should start a similar open-source project.
I vote for making Maya,3dmax,CATIA against the law! I also Vote for making FireGL and Quatro against the LAW!
no more apologies and excuses!
