App falling back to software renderer

  • Hi,

    I have a Qt-Quick application which I cross compile to windows. I use qt 5.15.2. Performance under windows is terrible, starting with QSG_INFO=1 revealed that it is using the software renderer (GL_RENDERER softpipe).

    How can I find out why it is using the software renderer and not opengl?

    Thanks for your help,

    Usually the first step is to check your graphics card and its drivers to see if they support a recent enough version of OpenGL.

    Some information can be found here.

  • The qtdiag diagnostic program might be helpful.
