How to get OpenGL acceleration on X11?
Does anyone know how to get OpenGL acceleration on X11?
http://qt-project.org/doc/qt-4.8/qtopengl.html is independent of the window system.
I use the command:
but I didn't see any acceleration with the device performance...
(I am trying to use the acceleration on qml application and not on new opengl application).
Both Qt Quick 1 as well as the QWidgets do not profit too much from GL acceleration. In one case a QWidget UI of mine was even slower with GL than it is with the raster graphics engine.
That is the reason for having Qt Quick 2 in Qt5, which does profit a lot more.
What can I do now in QT 4.7/4.8 to improve the qml performance, or use some how the GL abilities?
