When I was a student at SGI and OpenGL was replacing IrixGL? it was never pushed as cutting edge graphical porn. It was promoted as an easy to use, cross platform graphics language with emphasis on 3D apps that could also be used for games. Which it still is of course. Hands up I don't know what graphical advantages Direct3D has over OpenGL but I do know the games market probably doesn't care. PC games are dying on their arse. Witness the shrinking shelf space for PC games compared to the Wii in the Uk (I don't know about other countries). I have a hunch that OpenGL is good enough for Autodesk and good enough for most gamers.
