Windows 10 includes WDDM 2.0, which is designed to dramatically reduce workload on the kernel-mode driver for GPUs that support virtual memory addressing, [37] to allow multithreading parallelism in the user-mode driver and result in lower CPU utilization.
Network device drivers for Windows XP use NDIS 5.x and may work with subsequent Windows operating systems, but for performance reasons network device drivers should implement NDIS 6.0 or higher. [8] Similarly, WDDM is the driver model for Windows Vista and up, which replaces XPDM used in graphics drivers.
In Direct3D 11, the concept of feature levels has been further expanded to run on most downlevel hardware including Direct3D 9 cards with WDDM drivers.. There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while ...
Direct3D 12 for Windows 10 requires graphics hardware conforming to feature levels 11_0 and 11_1 which support virtual memory address translations and requires WDDM 2.0 drivers. There are two new feature levels, 12_0 and 12_1, which include some new features exposed by Direct3D 12 that are optional on levels 11_0 and 11_1. [ 158 ]
Drivers that may be vulnerable include those for WiFi and Bluetooth, [19] [20] gaming/graphics drivers, [21] and drivers for printers. [ 22 ] There is a lack of effective kernel vulnerability detection tools, especially for closed-source OSes such as Microsoft Windows [ 23 ] where the source code of the device drivers is mostly proprietary and ...
Intel introduced DirectX 10 for the X3100 and X3500 GPUs in the Vista 15.9 drivers in 2008, though any release of DX10 drivers for the X3000 is uncertain. WDDM 1.1 is supported by X3100 but DXVA-HD is not. OpenGL 2.0 support is available since Vista 15.11 drivers [63] and XP 14.36 drivers. [64] Windows 8 ships with a driver for the X3100. [65]
DWM works in different ways depending on the operating system (Windows 7 or Windows Vista) and on the version of the graphics drivers it uses (WDDM 1.0 or 1.1). Under Windows 7 and with WDDM 1.1 drivers, DWM only writes the program's buffer to the video RAM, even if it is a graphics device interface (GDI) program.
Windows Driver Frameworks (WDF, formerly Windows Driver Foundation), is a set of Microsoft tools and libraries that aid in the creation of device drivers for ...
