I made the mistake of upgrading my laptop to from Windows7 to Windows10...
Browsing around the Intel support web pages, I found my graphics card (formerly code-named Cantiga) on the "Legacy Intel Graphics Products" page at:
Unfortunately, it appears that there is no updated driver for this hardware now that I am running Windows10.
During the upgrade (from Windows7) process, I notice that Windows10 detected:
Chip type: Mobile Intel(R) 4 Series Express Chipset Family
and installed Driver Version: 188.8.131.5202, which seems to work, okay for the most part.
...However, I need to use an application that requires OpenGL support, and apparently my current driver doesn't support OpenGL.
So my question is: Does anyone happen to know whether Intel is in the process of making an updated Windows 10 driver available with OpenGL support for my Cantiga hardware?
