Works with DX No
Maybe Leadwerks meant 'Works with DX9'? In this case there is not an official support.
I really don't understand the topic of this thread 'Blitzmax - A gaming language?'. Is ASM a gaming language? or C++?
I think it's not the language itself, but the tools that come with it: if you have a 3d editor/world editor - 3d format converter and so on...is quite easy to define the 'language' a 'gaming language'.
If Bmax+MaxGUI comes with a GUI editor can be considered an 'application language'?
