I see, well POV-Ray is fast enough for me and about this permission I 
think the POV-Team could get it for free since they're developing a high 
quality and complex freeware that requires lots of effort and time whoch 
merits for some companies to donate some software to POV-Ray. I don't 
think nVidia or any other company have the audacity to charge a freeware 
developer team IMO.

True, AND Open-GL is more fluent when you rotate around an objet or 
objets are in motion than Direct X. I have experiencied this on games. 
When you move around in a Direct X game I see a little blur and I don't 
see this on Open-GL games. Considering the source of both technologies I 
don't find this strange.
