I''d like to know which of the 2 API is either better, easier to learn, better documented....and your personal opinion about them. I know that OpenGL can be used with any language, and DirectX is neither portable like OpenGL is nor can you use any language. But OpenGL only has the 3D graphics and stuff like DirectSound is missing. Is it right that you can implement DirectSound into OpenGL?? and is it still portable as without i.e DirectSound?? And again: which of the 2 API is either better, easier to learn, better documented...?

Well I''m probably the last person you would ask about comparing these two, but you can''t stop me from posting :D
From my (short) experience with both of these APIs, I prefer Directx. OpenGL definitely had the better graphics of the two (note: I''m speaking from limited experience), but I looked at all the games I owned, and all were made in DirectX, including Everquest, Diablo 2, etc. And personally I think (so far) that DirectX has been easier, but I''d recommend using both and seeing which you like better and work from there. Good luck to ya!
