OpenGL Version issue

[Mathieu Bisquay]

Hello,

I am trying to figure out what seems to be a recurring error:
PyQtGraph works fine in 2D but I do have a fez errors when trying the script "test3D.py"  enclosed in this message .

When executing the script ( test3D.py), the output displayed on the console is the following:

<module 'OpenGL' from 'C:\Python27\lib\site-packages\OpenGL\__init__.pyc'> 3.1.0

The original exception is printed above; however, pyqtgraph requires OpenGL version 2.0 or greater for many of its 3D features and your OpenGL version is 1.1.0. Installing updated display drivers may resolve this issue.

Also I updated pyopengl to 3.1.0 as it can be seen at the beginning of the error message ( highlighted in blue).
However the version 1.1.0 is also found (in orange there above).

Drivers on my computer were updated a couple of months ago (january 2017).
I used the windows installer of pyqtgraph V0.10.0 ...

Question is: How could that issue be solved?

Many thanks
