I have read the performance tweaking tips and i am little confused.
It says that :
"On all operating systems, use OpenGL hardware acceleration by supplying "-graphicssystem opengl" as command line argument or calling QApplication::setGraphicsSystem("opengl") (Only available for Qt versions before 5.0)."
So, isn't it possible to use OpenGL after Qt 5.0 ? If it is, how it is possible ?
By the way, i have no knowledge in OpenGL. I have lots of data and i need real time plotting, so, i 'm in need of really high performance.
