Немного ошибся я, но не настолько. Судя по статье ATI и nVidia где-то наравне.

Furthermore, Carmack made a brief comparison of the functionality of ATI and Nvidia offers. He mentioned, among other things, that the vertex program extensions provide almost the same functionality. However, the ATI hardware seemed to him a bit more capable, but not in a significant way. On the other hand, the ATI extension interface "is massively more painful to use" than the text
parsing interface from Nvidia. But, as one more point to ATI, the programmer noted that the Canadian company's vertex programs are invariant with the normal OpenGL vertex processing, which allowed him to reuse considerable amount of code. "The Nvidia vertex programs," he continued, "can't be used in multipass algorithms with standard OpenGL passes, because they generate tiny differences in depth values, forcing you to implement EVERYTHING with vertex programs. Nvidia is planning on making this optional in the future, at a slight speed cost."
