If you don't remember, try the fo= llowing: import OpenGL print(OpenGL.version.__version__) Remember that, despite appearances, this is the PyOpenGL version--the package.

During that process, you choose (or it's done for you). If you're asking about what your system supports, look up your GPU name for GL support. Alternately, the program "GPU Caps Viewer" will measure the capability of your GPU/driver combination and report in-detail.
