I run a CAD program which had been using OpenGL 4. After the update, it reported no OpenGL 4 support and reverted to OpenGL 1
When I check under <Sytem Settings><Display and Monitor><Compositor> it reports Rendering Backend as OpenGL3.1 and there is no option to choose OpenGL 4
I have an Nvidia GT470 card and driver is GeForce 420 series and later (chosen automatically by the system)
installed packages are

I had thought Mesa 17.3.9 package provided support for OpenGL 4.
Would appreciate any help you can give.
Thanks in advance.

You're currently using the nouveau driver, hence only software acceleration. That CAD program might require hardware acceleration.

Thank you. is there a way for me to get that?

Just checked.
glxinfo |grep direct gives: direct rendering: Yes
It is my understanding that this means that hardware acceleration is enabled, so I am at a loss for what to do.
Thank you

Follow up question: Will access to OpenGL4 under Nouveau be coming in the near future. I have lost some functionality in a program which worked prior to the upgrade.
Thank you
