Direct3D. Using standard Windows installable client driver (ICD), OpenGL will be fully accelerated and be fully compatible with Windows Vista's Aeroglass UI.

However, the OpenGL ICD drivers must still be downloaded and will not ship on the Windows Vista installation disc. Khronos said that NVIDIA already has a beta 2 ICD OpenGL driver available and ATI will release its own soon. If no ICD is present, Windows Vista will rely on the layered OpenGL mode by default and only offer basic functionality.
