I knew Windows came with Opengl drivers.

In fact, this is not the case. Windows comes with OpenGL emulation. But the actual OpenGL drivers are only available through the original vendor drivers.



how to determine the OpenGL version?

Create an OpenGL context and use a function glGetString

to get the identification values. Of greatest interest are GL_VERSION and GL_RENDERER.

You can use glGetString(GL_VERSION)

to get the current version of OpenGL.
