WARP is a full-featured Direct3D 10.1 renderer device with performance on par with current low-end graphics cards, such as Intel GMA 3000, [2] when running on multi-core CPUs. [3] To achieve this level of rendering performance, WARP employs advanced techniques such as just-in-time compilation to x86 machine code and support for advanced vector ...
This improves GDI performance and allows DWM to use local video memory for compositing, thereby reducing system memory footprint and increasing the performance of graphics operations. Most primitive GDI operations are still not hardware-accelerated, unlike Direct2D. GDI+ continues to rely on software rendering in Windows 7. [10]
DirectDraw (ddraw.dll) is an API that used to be a part of Microsoft's DirectX API.DirectDraw is used to accelerate rendering of 2D graphics in applications. DirectDraw also allows applications to run fullscreen or embedded in a window such as most other MS Windows applications.
In the "compositing" strategy, the window manager maintains an off-screen memory buffer containing the full appearance of each window, including the back window. With a stacking manager, the repainting process can become corrupted when a program that is slow, unresponsive or buggy does not respond to messages in a timely manner.
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.
In computer graphics, the render output unit (ROP) or raster operations pipeline is a hardware component in modern graphics processing units (GPUs) and one of the final steps in the rendering process of modern graphics cards.
User-mode memory dump, also known as minidump, [23] is a memory dump of a single process. It contains selected data records: full or partial (filtered) process memory; list of the threads with their call stacks and state (such as registers or TEB); information about handles to the kernel objects; list of loaded and unloaded libraries.
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
