	X-bit labs - Windows Vista for Gamers: Graphics Card Performance Preview (page 4)
		Although Windows Vista supports both driver models, the new user interface can only be used with a WDDM driver that supports the new WGF 1.0 API (and, later on, WGF 2.0).
		The WGF 2.0 API is sometimes referred to as DirectX 10 and is the next step in the evolution of the Windows Graphics Foundation.
		This is unlikely, however, considering the hardware requirements of WGF 2.0, but still it’s yet too early to discuss the advantages of the new API in earnest.

	Windows Vista - OnMac.net Wiki
		Windows Vista was deemed "code-complete" with the release of build 5308 CTP, released on February 22 2006, and much of the remainder of work between that build and the final release of the product will focus on stability, performance, application and driver compatibility, and documentation.
		Windows Sidebar: A new panel on the right-hand side of the screen where a user can place Desktop Gadgets(An exact copy of Apple's "Widgets"), which are small applets designed for a specialized purpose (such as displaying the weather or sports scores).
		Windows Vista is intended to be a technology-based release, to provide a solid base to include advanced technologies, many of which will be related to how the system functions, and hence not readily visible to the user.

	Windows Graphics Foundation - Wikipedia, the free encyclopedia
		The Windows Graphics Foundation (WGF) is a next-generation presentation subsystem of Microsoft that unifies a whole range of output services: user interface, 2-D and 3-D drawing and imaging, document-based printing and rendering, speech, and audio and video services.
		These new features include: cross-process shared surfaces, managed graphics memory (and virtualized graphics memory), prioritization of resources, text antialiasing, advanced gamma functions, and device removed (in order to gracefully recover from a failure the hardware can be "removed" and then "added").
		When the WGF is finalised, it will be included as standard in Windows Vista.

	Windows Presentation Foundation - Wikipedia, the free encyclopedia
		The Windows Presentation Foundation (or WPF), formerly code named Avalon, is the graphical subsystem feature for Microsoft Windows.
		All graphics will be routed through Direct3D, providing a unified avenue for display and more advanced graphical features.
		More advanced graphical effects, such as blurring and transparency, can provide a better connect with designers, who will be able to apply effects previously only accessible from dedicated graphical design programs.

	Create the Experience (Site not responding. Last check: 2007-10-16)
		A new graphics driver model has been introduced with Windows Vista that is stable and secure; it has built-in fault tolerance to enable constant use of the graphics processor unit (GPU) for the rich graphics sported by the operating system and the applications.
		Windows Presentation Foundation is built on top of Microsoft DirectX(r), which enables it to unleash the full power of the graphics hardware present in modern computers and is engineered to exploit advances in hardware moving forward.
		Windows Presentation Foundation is designed for extensibility, enabling developers to create their own controls on top of the Windows Presentation Foundation engine from scratch or by subclassing existing Windows Presentation Foundation controls.

		Aero is the codename for a Windows Vista shell; Windows Presentation Foundation is the graphics subsystem and developer platform.
		On Windows Vista, Windows Presentation Foundation relies on the version of Direct3D that is part of Windows Graphics Foundation 1.0 (the new name for DirectX, in part reflecting its new fundamental role going forward within Windows).

	Slashdot \| The End Of DirectX As We Know It
		WGF is roughly equivalent to OpenGL / Quartz Extreme and everything else that DirectX does at the moment, while Avalon is equivalent to Aqua / WindowServer.
		Seeing that graphics cards exceeds standard desktop computers in both processing power and memory capabilities, it was the logical choice to have the graphics do the OS, and not the other way around.
		A combination of graphics, sound, controllers, and network handling might sound good for a developer trying to get games to run on linux, but is worried about the costs of trying to find each component and hope it works on most people's computer.

		Graphics command streams are validated to prevent unauthorized used of one application's graphics resources from another application, and to prevent sending bad commands to the hardware.
		Graphics device virtualization opens up new scenarios such as hot-plug insertion and removal of graphics hardware (on hot-plug supporting systems), allowing GPU insertion or removal and configuration (new driver installation) without requiring a reboot.
		WGF 1.0 is an enhanced version of Direct3D 9.0 supporting managed memory resources, cross-process surface sharing, extended gamma range, and text antialiasing.

		Graphics technology moves faster than probably any other area of PC technology, doubling performance every year or so, and reinventing itself just as quickly.
		It appears that it will unify the vertex and pixel shaders into a generic shader language, where graphics cards would perform certain sets of operations on certain types of data, but these wouldn't necessarily have to be defined as verticies or pixels.
		The company has designed the graphics chip for Microsoft (and Nintendo's next console, for that matter, though the design teams are separate), and we hear it is based on the R500 core technology that will be the basis for their next-gen PC graphics, too.

	DriverHeaven.net - ATI and NVIDIA Proclaim Different Graphics Processors Architecture Goals
		While particular approaches in graphics processing units design have been pretty different for leading computer visual companies ATI Technologies and NVIDIA Corp., in future the architecture of GPUs from the firms may be fundamentally different, as executives from both companies proclaim different approaches for chip internal architectures.
		While he declined to elaborate on the timeframes for such chips, he said unified pixel and vertex data processing is a required capability for Windows Graphics Foundation 2.0 that comes out together with Microsoftâs next-generation operating system called Windows Longhorn.
		NVIDIA Corp.âs chief architect David Kirk called the unified graphics engines as an implementation detail, not a feature, but admitted the unified architecture would be nice for programmers, who would have one instruction set for vertex and pixel shaders.

		I wonder what the motivation behind WGF is. It seems distinct enough to discontinue it from the DirectX line.
		Foreshadowing this, all capability bits have been eliminated from WGF 2.0 (meaning that either hardware will or will not support exactly the same set of functions as all other WGF 2.0 hardware).

		A new 3D graphics architecture in Longhorn, called Windows Graphics Foundation (WGF), will be responsible for rendering the Windows desktop.
		The upshot is that there are changes in the certain graphic functions are being eliminated and consolidated, with the end result being a more stable operating system with better crash recovery capabilities.

	WinG at AllExperts
		The original Windows Graphics Device Interface (GDI) was designed with static images in mind, making its animation capabilities very limited.
		The GDI provides an interface to the graphics hardware that is device independent, that is, a program written using the GDI will work on all graphics and printer hardware, provided suitable Windows GDI drivers for the hardware are installed on the system.
		This meant that fast graphics algorithms could be written to allow fast scrolling, overdraw, dirty rectangles, double buffering, and other animation techniques.

		If an application's display processing chores can't preemptively be given higher priority when that app comes into the foreground focus, we wonder if there might be some perceptible latency as other instructions are retired and the in-focus app's processing gets the driver's full attention.
