Microsoft's Graphics group is very close to finally releasing the long awaited next generation DirectX. You can forget the name DirectX as Microsoft has decided to call this one WGF (Windows Graphic Foundation).
The interface will, for the first time, reunite Direct Draw part that was mainly used for drawing 2D windows and Direct 3D part of DirectX used to draw 3D scene.
WGF will unite them into one item. It is intended to change things by allowing graphics subsystems to be served with as much performance as you will need.
