Where did you get that from? The best info I have been able to find says
OpenGL 1.1 with no extensions.

I have tried to keep this thread from being an MS bashathon and have
nearly succeeded. The best I have been able to figure out what happened
to the students in my class is that they had either Intel integrated
graphics systems or very old graphics cards that have lousy 3D
performance and no vendor OpenGL support. Go figure....
Also, I found that scitechsoft.com has a $19.95 version of OpenGL hosted
on DirectX that works just fine and that that code is working its way
back into Mesa. So, by the time vista gets here there should be several
ways to get high performance OpenGL on Vista. But, you will have to be
smart enough to install it and have hardware that will support it. OTOH,
the graphics requirements for Vista are so high that anyone running it
will have the graphics hardware needed to support high performance
OpenGL.
