stickyboot writes "The independent games developer Wolfire describes why they decided to use OpenGL instead of DirectX. The article mainly discusses the marketing strategies behind DirectX and how the API became so popular. It also goes over why a developer would choose OpenGL over DirectX and what this decision means for the gamer. 'Back in 1997, the situation was similar to how it is now. Microsoft was running a massive marketing campaign for Direct3D, and soon everyone "just knew" that it was faster and better than OpenGL. This started to change when Chris Hecker published his open letter denouncing DirectX. Soon after that, John Carmack posted his famous OpenGL rant, and put his money where his mouth was by implementing all of Id Software's games in OpenGL, proving once and for all that DirectX was unnecessary for high-end 3D gaming. This lesson appears to have been forgotten over the last few years. Most game developers have fallen under the spell of DirectX marketing, or into the whirlpool of vicious cycles and network advantages.'"
