Replace OpenGL with DirectX?

Hello, OpenGL not working in my laptop, I installed CrazyBump for creating normal maps, and this program contains a Realtime 3D Preview(using DirectX), in the realtime 3d preview work very good the normal maps and all shaders! How can use DirectX in Blender Game engine?

You can’t. OpenGl is the open standard that works cross platform, so that’s why it is used in blender.
