You're asking for 32 depth bits. That's a rather unusual format. Typical choices are 24 depth bits and 8 stencil bits in a combined 32 bit depth-stencil format. Also you can use glfwOpenWindowHint
to request an OpenGL-3 context, which should give you a context on the NVidia GPU.
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 0);
err = glfwOpenWindow(...);
