I'm not a c++ person, but assuming you are using qgraphicsview
you just need to assing our viewport to a QGLWidget, qt will take care of using GL

Code:
ui.graphicsView->setViewport(new MyGLWidget(QGLFormat(QGL::DoubleBuffer)));

Ok it means that i have to change QGraphicScene to QGLWidget? Are you sure that huge cpu consumption is normal?

you should not need to change anything. just assign a glwidget to your viewport.
nclock uses qgraphicsview and and i am updating 6 times a second and using 70 percent cpu. glwidget gets it down to about 40 percent without any optimization. still not brilliant but better.
