If you put this code in your init routine, you'll be able to know what you're really using in OpenGL
char *r = (char *)glGetString(GL_RENDERER);
char *v = (char *)glGetString(GL_VENDOR);
char *ver = (char *)glGetString(GL_VERSION);
char *ext = (char*)glGetString(GL_EXTENSIONS);
Then you run in debug mode and put a break point in front of the first line. A few step latter, you'll be able to know if you use hardware or generic renderer.
