GDI is no longer hardware-accelerated, but instead rendered to system memory using the CPU. All these resources add up and increase the video memory footprint. In order for Windows Vista to perform compositing, DWM allocates an extra window-sized compositing buffer for each top-level window in the system. This is also true when the Desktop Windows Manager (DWM) is off. Each OpenGL window now requires an offscreen frontbuffer, because there's no longer direct access to the surface being displayed: the desktop. Graphics applications now have to share resources with the 3D-accelerated window manager.

The user will then see a popup bubble notifying that the 'Display driver stopped responding and has recovered.'Д¬hanges Introduced by the Desktop Window Manager When a command buffer spends too long in the graphics chip (more than two seconds), the operating system assumes the chip is hung, kills all the graphics contexts, resets the graphics chip and recovers the graphics driver, in order to keep the operating system responsive. This is achieved via Windows Vista's Timeout Detection and Recovery (TDR). In short, this means that multiple simultaneous graphics applications can be running in round robin as scheduled by Windows Vista's Video Scheduler and their working sets (video resources) will be paged in, as needed, by Windows Vista's Video Memory Manager.Д«eing that the video hardware is virtualized, user-mode components (the OpenGL ICD is one of those) no longer have direct access to that hardware, and need a kernel transition in order to program registers, submit command buffers, or know the real addresses of the video resources in memory.Д«ecause Windows Vista controls the submission of graphic command buffers to the hardware, detecting hangs of the graphics chip due to invalid programming is now possible across the operating system. Under WDDM, Microsoft takes ownership of the virtualization of video resources at the video memory level, but also at the graphics engine level.

Changes Introduced by the New Windows Display Driver Model For example, both Direct3D and OpenGL will get transparency and dynamic thumbnails when Windows Aero is on, and all the WDDM features (video memory virtualization, etc.) will work in a similar fashion.

OpenGL and Direct3D are treated the same by Windows Vista, resulting in full integration into the OS for both APIs.

The new Desktop Window Manager with its Desktop Compositing Engine provides 3D accelerated window composition when Windows Aero is turned on.

The new driver model, Windows Display Driver Model (WDDM), formerly known as Longhorn Display Driver Model (LDDM).

The two biggest changes that Windows Vista brings to OpenGL are:

Just like Windows XP, Windows Vista does not contain an OpenGL ICD 'in the box.' End users will need to install drivers from OEMs or video hardware manufacturers in order to access native hardware-accelerated OpenGL. Microsoft's software OpenGL 1.1 implementation (renderer string is GDI Generic), is clustered in higher numbered pixel formats.The OpenGL version supported depends on the hardware manufacturer. Hardware manufacturers provide OpenGL ICD (installable client driver) with variable renderer string.Windows Vista supports two primary OpenGL implementations: So Windows Vista is here, but what does it mean for an OpenGL user and developer? In this article we will try to give OpenGL application developers a quick peek at what to expect and the current state of OpenGL on Windows Vista.
