I don't think you can select this before the aplication is launch, it's
Windows and the video driver that choose that for you. You could however,
have a small launcher or a checker on application launch with the OpenGL
card used (maybe inspect the QSurface format or anything that could point
to if the wanted OpenGL features is available).
you can execute the following batch script to get the video card
///////// VideoCardIdentifier.bat
*@echo off*
*for /F "tokens=* skip=1" %%n in ('WMIC path Win32_VideoController get Name
^| findstr "."') do set GPU_NAME=%%n*
*echo %GPU_NAME%*
///////// END VideoCardIdentifier.bat
should output something like that:
*AMD Radeon R9 200 Series*
use a regex to parse the output to detect the available card type.
You could show an error dialog and stop at this point and tell the
requirement to your user. I would point. depending on the nvidia or AMD
card detected, you could try to launch the proper panel and display the
instruction to change it or give a link to do it.
