Il2 uses a wrapper for DirectX that basically translates OpenGL into DX on-the-fly. It is still running OpenGL under the hood. This is not very efficient but was probably included for compatibility reasons, as nobody could be sure where OpenGL would be going.

In the last 10 years DirectX has matured a lot, while OpenGL is unfortunately not going anywhere. It's definitely the better choice these days to stick with DirectX, even though in theory you can achieve pretty much the same results in both APIs.
