Why no progress in the Directx plugin?

[omegadox]

The DX9 plugin is broken because the Cg Vertex and Pixel Shader code fail to compile with the CgD3D9 API and no one can figure out why.

Both Direct3D 11 and OpenGL can do the same work on the GPU, however the APIs have their own advantages

Direct3D:
- Strongly supported by ATI Graphics Cards
- More cards support it including really junky ones
- Easier API to work with
- Dedicated SDK and MSDN Library
- Control over where textures are stored (VRAM or RAM)

OpenGL:
- Cross-Platform
- Smaller Library
- Legacy API - allowing more direct control over the graphics engine
- Open Source
- Vendors can add their own extensions to it
