Many modern GPUs rely on VRAM. In contrast, a GPU that does not use VRAM, and relies instead on system RAM, is said to have a unified memory architecture, or shared graphics memory. System RAM and VRAM have been segregated due to the bandwidth requirements of GPUs, [2] [3] and to achieve lower latency, since VRAM is physically closer to the GPU ...
DirectDraw uses hardware acceleration if it is available on the client's computer. DirectDraw allows direct access to video memory , hardware overlays , hardware blitters , and page flipping . Its video memory manager can manipulate video memory with ease, taking full advantage of the blitting and color decompression capabilities of different ...
Dual-ported video RAM (VRAM) is a dual-ported RAM variant of dynamic RAM (DRAM), which was once commonly used to store the Framebuffer in Graphics card, Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
Most video cards manufactured since about 1998 and most media players support hardware overlay. [1] The overlay is a dedicated buffer into which one app can render (typically video), without incurring the significant performance cost of checking for clipping and overlapping rendering by other apps. The framebuffer has hardware support for ...
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.

The functional blocks (the application-specific integrated circuit display driver, 2- and 3D acceleration and video decoding and encoding) are separate semiconductor intellectual property (SIP) blocks on the chip, since hardware devices vary substantially; some portable media players require a display driver that accelerates video decoding, but ...
A common design uses a graphics library such as OpenGL or Direct3D which interfaces with the graphics driver to translate received commands to instructions for the accelerator's graphics processing unit (GPU). The GPU uses those instructions to compute the rasterized results and the results are bit blitted to the framebuffer. The framebuffer's ...
Radeon Software 17.7.1 is the final driver for Windows 8.1. Radeon Software 18.9.3 is the final driver for 32-bit Windows 7/10. AMD Software 22.6.1 is the final driver for Windows 7 (and Windows 8.1 unofficially); 22.6.1 is also the final driver for GCN 1, GCN 2 and GCN 3 based GPUs [42]
