KDE

Plasma 2 Technology Preview demonstrates the current development status. The Plasma 2 user interfaces are built using QML and run on top of a fully hardware accelerated graphics stack using Qt5, QtQuick 2 and an OpenGL(-ES) scenegraph. Plasma 2 is a converged workspace shell that can run and switch between user interfaces for different formfactors, and makes the workspace adaptable to a given target device.

Plasma 2 is not a complete rewrite; it's a port to a new graphics system (a fully hardware accelerated OpenGL(ES) scenegraph).

3D support required?

What does this mean for computers that have older graphics cards or poor Linux driver support for advanced compositing/3D graphics functions? Does this mean that KDE will be added to the list of desktop environments that won't run until proper compositing/3D graphics support is enabled on the base system?

For example, Gnome 3.x and Cinnamon and Unity have LLVMpipe support, but on many systems they still won't load until proprietary drivers are configured. Or, if they do load, they run dreadfully slowly as the CPU tries to do the work of the GPU. This is common on Nvidia and Radeon systems. Fortunately systems with Intel graphics usually work better out of the box.

I always admired KDE 4 (although I can't stand it for other reasons that don't matter in this discussion) because it allows the user to select the graphics backend for rendering effects. It defaults to some basic, standard, X protocol (don't remember the name) for basic rendering, which works well out of the box on virtually any system. No "fallback mode" or drastic interface changes required to get basic functionality from the computer. Then later if the user wants to he can change the rendering method to something more advanced, including openGL. Will this be maintained in KDE 5? Or will KDE be added to the list of desktop environments that lead to initial failure due to graphics issues, and new users subsequently giving up on Linux at first sight because "it doesn't work" or "it's awfully slow"?

I'm not trying to harass anybody about this, but it does genuinely concern me and I'd like to know.
