Windows Display Driver Model ( WDDM) is the architecture for running versions beginning with. It is a replacement for the previous and display driver model XDDM/XPDM and is aimed at enabling better performance graphics and new graphics functionality and stability. Display drivers in Windows Vista and can choose to either adhere to WDDM or to XDDM. With the removal of XDDM from, however, WDDM became the only option. WDDM provides the functionality required to render the desktop and applications using, a running on top of. It also supports new interfaces required for basic device management and creation. The WDDM specification requires at least Direct3D 9-capable video card and the display driver must implement the for the Direct3D 9Ex runtime in order to run legacy Direct3D applications; it may optionally implement runtime interfaces for /10.1 and higher.
Contents. Features enabled by the WDDM WDDM drivers enable new areas of functionality which were not uniformly provided by earlier display driver models.
These include: Virtualized video memory In the context of graphics, virtualization means that individual processes (in ) cannot see the memory of adjacent processes even by means of insertion of forged commands in the command stream. WDDM drivers allow video memory to be virtualized, and video data to be of video memory into system RAM. In case the video memory available turns out to be insufficient to store all the video data and textures, currently unused data is moved out to system RAM or to the disk.
When the swapped out data is needed, it is fetched back. Virtualization could be supported on previous driver models (such as the XP Driver Model) to some extent, but was the responsibility of the driver, instead of being handled at the runtime level. Scheduling The runtime handles scheduling of concurrent graphics contexts. Each list of commands is put in a queue for execution by the, and it can be preempted by the runtime if a more critical task arrives and if it has not begun execution.

Driver models: Windows Display Driver Model (WDDM 1. It would help us a lot if you could post your Dell system model and operating system and if you know the make and model of your video card. Vista Drivers are WDDM 1.0 there are no updates to WDDM 1.1 that requires HARDWARE. WDDM v1.2 is a superset of WDDM v1.1, and WDDM 1.0. Report Unresolved Customer Service Issues.
This differs from native threads on the CPU where one task cannot be interrupted and therefore can take longer than necessary and make the computer appear less responsive. A hybrid scheduling algorithm between native and light threads with cooperation between the threads would achieve seamless parallelism. It is important to note that scheduling is not a new concept but it was previously the responsibility of individual driver developers. WDDM attempts to unify the experience across different vendors by controlling the execution of GPU tasks. Cross-process sharing of Direct3D surfaces A graphics surface is the memory area that contains information about the used for rendering a 2D or 3D scene. WDDM allows Direct3D surfaces to be shared across. Thus, an application can incorporate a mesh created by another application into the scene it is rendering.
Sharing textures between processes before WDDM was difficult, as it would have required copying the data from video memory to system memory and then back to video memory for the new device. Enhanced fault-tolerance. Windows Vista alerting the user of a successful WDDM recovery If a WDDM driver hangs or encounters a fault, the graphics stack will restart the driver. A graphics hardware fault will be intercepted and if necessary the driver will be reset.
Drivers under Windows XP were free to deal with hardware faults as they saw fit either by reporting it to the user or by attempting to recover silently. With a WDDM driver, all hardware faults cause the driver to be reset and the user will be notified by a popup; this unifies the behavior across vendors. Previous drivers were fully implemented in kernel mode, whereas WDDM is implemented partly in user mode. If the user mode area fails with an unrecoverable error, it will, at the most, cause the application to quit unexpectedly instead of producing a as it would in previous driver models. WDDM also allows the graphics hardware to be reset and users to update drivers without requiring a reboot. Limitations The new driver model requires the graphics hardware to have Shader Model 2.0 support at least, since the fixed function pipeline is now translated to 2.0.
However, according to Microsoft as of 2009, only about 1–2 percent of the hardware running Windows Vista used the XDDM, with the rest already WDDM capable. It also requires some other hardware features; consequently some SM 2.0-supporting hardware such as the 900 fails the WDDM certification. One of the limitations of WDDM driver model version 1.0 is that it does not support multiple drivers in a multi-adapter, multi-monitor setup.
If a multi-monitor system has more than one graphics adapter powering the monitors, both the adaptors must use the same WDDM driver. If more than one driver is used, Windows will disable one of them.
WDDM 1.1 does not have this limitation. WDDM 1.0/1.1 does not allow some modes that were previously handled by the driver such as spanning mode (stretching the desktop across two monitors) although Dual View is still available. Need for a new display driver model One of the chief scenarios the Windows Display Driver Model enables is the. Since the desktop and application windows managed by DWM are Direct3D applications, the number of open windows directly affects the amount of video memory required. Because there is no limit on the number of open windows, the video memory available may prove insufficient, necessitating virtualization. As the window contents that DWM composes into the final desktop are generated by different processes, cross-process surface sharing is necessary.
Also, because there can be other DirectX applications running alongside DWM on the DWM-managed desktop, they must be able to access the GPU in a shared manner, necessitating scheduling. Though this is true for Microsoft's implementation of a composited desktop under Windows Vista, on the other hand, a composited desktop need not theoretically require a new display driver model to work as expected.
Successful implementations of composited desktops were done before Windows Vista on other platforms such as,. The approach Microsoft attempted was to try to make sure WDDM was a unified experience across different GPUs from multiple vendors by standardizing their features and performance. The software features missing from other driver models could be made immaterial by extensions or if a less restrictive or simply different driver model was in place. History WDDM 1.0 Windows Vista introduced WDDM 1.0 as a new display driver architecture designed to be better performing, more reliable, and support new technologies including., which combines and functionality for enhanced stability in the event of power failure, also requires WDDM.
WDDM 1.1 Windows 7 supports major additions to WDDM known as WDDM 1.1; the details of this new version were unveiled at 2008. New features include:. 1.1, which features return of hardware acceleration for use by (but not GDI+) and /., StretchBlt, TransparentBlt., ColorFill. font support. interface (DDI). DDI.
DDI. Optional encryption. Optional decoding of encrypted video content.
Support multiple drivers in a multi-adapter and multi-monitor setup Hardware acceleration of GDI and Direct2D/DirectWrite operations helps reduce memory footprint in Windows 7, because DWM compositing engine no longer needs to keep a system memory copy of all surfaces used by GDI/GDI+, as in Windows Vista. DXGI 1.1, Direct3D 11, Direct2D, and DirectWrite were made available with; however GDI/GDI+ in Vista continues to rely on software rendering and the continues to use Direct3D 9Ex. WDDM 1.1 drivers are backward compatible with WDDM 1.0 specification; both 1.0 and 1.1 drivers can be used in Windows Vista with or without the Platform Update. WDDM 1.2 Windows 8 includes WDDM 1.2 and DXGI 1.2.
New features were first previewed at the 2011 conference and include performance improvements as well as support for rendering and video playback. Other major features include of the GPU with finer (DMA buffer, primitive, triangle, pixel, or instruction-level), reduced memory footprint, improved resource sharing, and faster timeout detection and recovery. 16-bit color surface formats (565, 5551, 4444) are mandatory in Windows 8, and Direct3D 11 Video supports YUV video formats with 8, 10, and 16-bit precision, as well as 4 and 8-bit palettized formats. WDDM 1.2 supports display-only and render-only WDDM drivers, such as Microsoft Basic Display Driver and -based Microsoft Basic Render Driver which replaced kernel-mode driver. WDDM 1.0/1.1 only allows rudimentary task scheduling using 'batch queue' granularity; improvements to multitasking, as well as fast context switching and support for, were initially expected in versions tentatively named WDDM 2.0 and WDDM 2.1, which were announced at 2006.
WDDM 1.3 includes WDDM 1.3 and DXGI 1.3. New additions include the ability to trim DXGI adapter memory usage, multi-plane overlays, overlapping swap chains and swap chain scaling, select backbuffer subregion for swap chain and lower-latency swap chain presentation. Driver feature additions include wireless displays , format ranges, cross-adapter resources and GPU engine enumeration capabilities. Graphics kernel performance improvements. WDDM 2.0 includes WDDM 2.0, which is designed to dramatically reduce workload on the kernel-mode driver for GPUs that support virtual memory addressing, to allow multithreading parallelism in the user-mode driver and result in lower CPU utilization.
Windows 10 also includes DXGI 1.4. Direct3D 12 API, announced at, requires WDDM 2.0. The new API will do away with automatic resource-management and pipeline-management tasks and allow developers to take full low-level control of adapter memory and rendering states.
The display driver model from Windows 8.1 and Windows Phone have converged into a unified model for Windows 10. A new memory model is implemented that gives each GPU a per-process virtual address space. Direct addressing of video memory is still supported by WDDMv2 for graphics hardware that requires it, but that is considered a legacy case. IHVs are expected to develop new hardware that supports virtual addressing. Significant changes have been made to the DDI to enable this new memory model. WDDM 2.1 10 Anniversary Update (version 1607) includes WDDM 2.1, which supports Shader Model 6.0 (mandatory for 120 and 121), and DXGI 1.5 which supports - a 10-bit high dynamic range, wide gamut format defined by ITU-T / - and variable refresh rates.
WDDM 2.2 Windows 10 Creators Update (version 1703) includes WDDM 2.2, which is tailored for, and with for the platform, and DXGI 1.6. WDDM 2.3 Windows 10 Fall Creators Update (version 1709) includes WDDM 2.3.

When i downloaded a WDDM 1.0 driver from Microsoft Catalog.it worked and installed correctly but the problem is now appearing.when i hover at start menu icons the letters goes invisible. But when i restore Microsoft Basic Display Driver it works fine with bad resolution.
The words are hidden:/ i came to understand that when i switch back to ms basic display driver the Driver Model of that was WDDM 1.3 with directx 11,2.on the other hand the driver model i downloaded from catalog is WDDM 1.0 with directx 9e:/ if anyone understands my problem kindly fix this. Work through the to make sure it's set up correctly, optimized for best performance, and any repairs are done. If that doesn't sort the correct driver from Windows Update then go to the PC or Display device's Support Downloads webpage to import the latest driver for WIndows 10, 8.1, 8 or 7 in that order. For AMD you can also try to compare it's findings. If only an older driver is available it might be necessary to install it in If in doubt you can trace the device's and even search by the full HID for drivers and issues per Windows 10. I am a volunteer and not Microsoft. Approaching 100,000 helped in forums.
