Technically, supporting a specific game is not how development works, games and 3d apps have requirements that involve versions of OpenGL, DirectX, Pixel Shaders and Vertex Shaders, development works to support specific versions of these 'standards' to meet the games and apps requirements. PDM 4 supports higher versions of these than PDM 3.
The game page only refers the requirement of DirectX 9.0c.
The PDM 4 features page says:
Expanded DirectX 9, DirectX Pixel Shader 2.0 and OpenGL 2.0.
So, I believe it doesn't work because PDM 4 doesn't fully support DX9c (yet).
