To use Qml on Win8 Metro, we must have a directX backend (with or without
angle .. but it seems that for now angle is directX9 only and Metro need
DX11), and to be able to use qt5 qml for digital signage on low end
hardware ( in that case qt5 qml is just perfect...) we need to have
hardware acceler

We've just added ANGLE support in Qt (-angle ), to enable DirectX
usage instead of OpenGL ES 2 on Windows, due to many buggy drivers.
How will this effort affect this usage?
Will we ac

Which features are we talking about here?
I have been thinking that we could add something equivalent to the rasterwindow
I did for the examples here:
