It is a replacement for the previous Windows 2000 and Windows XP display driver model XDDM/XPDM [3] and is aimed at enabling better performance graphics and new graphics functionality and stability. [2] Display drivers in Windows Vista and Windows 7 can choose to either adhere to WDDM or to XDDM. [4]
Built-in benchmarking tool that analyzes the different subsystems (graphics, memory, etc.), and uses the results to allow for comparison to other Windows Vista systems, and for software optimizations. It rates the computer's performance using the Windows Experience Index. winsat.exe: Windows Vista: System Restore
Direct2D performance and memory usage scale linearly with primitive counts in both software and hardware. Direct2D [6] [7] supports high-quality rendering with the following key features: High-quality subpixel text rendering via DirectWrite for both grayscale and ClearType technique; Per-primitive antialiasing; Bézier geometry draw and fill

DirectX Graphics Infrastructure (DXGI) [1] is a user-mode component of Microsoft Windows (for Windows Vista and above) which provides a mapping between particular graphics APIs such as Direct3D 10.0 and above (known in DXGI parlance as producers) and the graphics kernel, which in turn interfaces with the user-mode Windows Display Driver Model driver.
SharpDX, [99] [100] which is an open source project delivering the full DirectX API for .NET on all Windows platforms, allowing the development of high performance game, 2D and 3D graphics rendering as well as real-time sound applications; DirectShow.NET for the DirectShow subset
Some performance improvements could be seen in memory management and graphics display, but other parts of OS have equal or lower performance than Windows XP. On a low-end computer system, Windows XP outperformed Windows Vista in most tested areas. Windows OS network performance depends on the packet size and used protocol. However, in general ...
Performance Monitor (known as System Monitor in Windows 9x, Windows 2000, and Windows XP) is a system monitoring program introduced in Windows NT 3.1. It monitors various activities on a computer such as CPU or memory usage.
