OpenGL has nothing to do with content protection - as I read the article Microsoft has dropped support for this library in Vista, in favour of their own (proprietary) DirectX. "There are some programs that showed deeply disappointing performance. Unreal Tournament 2004 and the professional graphics benchmarking suite SPECviewperf 9.03 suffered heavily from the lack of support for the OpenGL graphics library under Windows Vista. This is something we expected, and we clearly advise against replacing Windows XP with Windows Vista if you need to run professional graphics applications. Both ATI and Nvidia will offer OpenGL support in upcoming driver releases, but it remains to be seen if and how other graphics vendors or Microsoft may offer it." <http://tinyurl.com/2uysns> Stroller.
