I'm not sure, but doesn't Matrox have the MGA Impression + boards that support
OpenGL under NT 3.5? I think it does coz' I have the MGA and the manual says
it does although I do not have any OpenGL apps nor do I run NT to be sure if it
works. Also, a new board from Kubota supports OpenGL which is said to be super
fast (and also cost around 2 grand….) I think it's call the Action Graphics.
You'll see a bunch of them come out by next year like the Glint chips and all
that stuff when NT gets more popular. I hope this info will help you somehow.
