Render more than 60 fps

[kDohmen]

Hello,

I need to know if Qt renders more than 60 fps even if QScreen.refreshRate() returns 60?
At the moment I just use the openglwindow example and filled the render(QPainter* painter) function. Do I need to change something on the example code to run with more frames or is it impossible? Or does it run with the maximal possible framerate which may be higher than QScreen.refreshRate?

Additional info: I use a raspberry pi (1 B) and forced more than 60 hz but QScreen.refreshRate() returns 60. But I need 120 fps to archive my goal.
