It's not specific to qmlviewer and should work everywhere. Just make sure you got that environment variable set in the environment where you run you application. If you use QtCreator, you can set it in the Project/Run settings. > Approximately for a second, it prints all this information: > > paintEvent: 0 time since last frame: 16 > paintEvent: 0 time since last frame: 16 > paintEvent: 0 time since last frame: 15 > paintEvent: 0 time since last frame: 18 > paintEvent: 0 time since last frame: 13 > paintEvent: 0 time since last frame: 19 > paintEvent: 0 time since last frame: 12 > paintEvent: 0 time since last frame: 16 > paintEvent: 0 time since last frame: 15 > paintEvent: 0 time since last frame: 16 > paintEvent: 0 time since last frame: 16 > > Do you have any idea how to calculate the Frame-Rate per Second, out of this? The values you see are milliseconds since the last repaint with the limited timer resolution available. 1s / 0,016s = 62,5fps. In the pre-scenegraph era the repaints aren't synchronized to the display refresh rate so you can't get perfectly smooth animation even if your scene can be rendered faster than the display refresh rate.
