Some former critics of Direct3D acknowledge that now Direct3D is as good if not better than OpenGL in terms of capabilities and ease of use. In January 2007, John Carmack said that "…DX9 is really quite a good API level. Even with the D3D side of things, where I know I have a long history of people thinking I'm antagonistic against it. Microsoft has done a very, very good job of sensibly evolving it at each step—they're not worried about breaking backwards compatibility—and it's a pretty clean API. I especially like the work I'm doing on the 360, and it's probably the best graphics API as far as a sensibly designed thing that I've worked with.

Doubt is not a pleasant condition, but certainty is absurd.
