​So . . . like, *how* lost? Have you used compute shaders before? OpenGL
before? PyOpenGL before?

​Whichever version you installed. If you don't remember, try the following:
import OpenGL
print(OpenGL.version.__version__)

Remember that, despite appearances, this is the PyOpenGL version--the
package. It doesn't say anything about what the OpenGL context can do
(that's also how it's possible to get this information without a GL
context).

​Create a context using your favorite windowing system. 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.

Second, is it possible to update to OpenGL 4.3

​The latest PyOpenGL (currently 3.1.0, I believe) should support
everything. It has a module for compute shaders, though I haven't used it
myself.
