“We use OpenGL for Brink. Partially because of our legacy, partially because it provides a nice platform for cross DX9 and DX10+ class hardware, partially because of the portability. Yes, D3D has some nice debugging tools that at times I wish I’d have for GL, but at the same time there is not enough of a reason to change to D3D and support two renderer backends on the PC (D3D9 and D3D10+).

And I guess the Source engine will be using Ogl for Mac.
