OpenGL is built into the core of Mac OSX right? Then why does it seem that OpenGL games run better on a PC? Especially when I thought PCs just use OpenGL extensions. Is it a poor job of porting? I havent played Quake III, but I know its OpenGL, so does it run better on a Mac? Also, why did Half-Life not appear on the Mac platform? I read it was because the Mac version had to be too watered down to play well. But its an OpenGL game! How could a game written in OpenGL not perform well on an OpenGL system? Will OpenGL 2.0 correct this? Im completely not trolling, but I am frustrated with this situation. Can someone please help me understand this? Am I missing something?
