This enables them to the working memory of the system in addition to the video memory to enable textures to be accommodated.
Microsoft used to include a view of the planet Mars 3GB for his demonstration, which zoomed in to ground level to gullies and cracks in the surface and in the memory of the graphics card is only 16MB was used. In another demonstration of middlewareproduct Granite of the Belgian graphical company Graphine could on the tiny details of the four gliders zoomed in.
