Questions of portability and system support. I've seen the questions of "why DX9" and "why not OpenGL" come up in discussion, so I thought I would ask it directly: Why does Forgelight use DirectX 9 instead of DirectX 11?Why does Forgelight use DirectX at all?Was either OpenGL or SDL considered for Forgelight?After the Mac port, will OpenGL be available as a renderer on the Windows version of Forgelight? I would be especially curious as to why OpenGL is not used, since that the eventual Mac port will require it.
