Wud be interesting where the option “shared system memory” is set by windows. I have 256 MB physical on my card. Windows shows 256 MB dedicated + 512 MB shared System. System memory shows 0. As i’am using a AGP card i set 256 MB AGP-ApertureSize in Bios. I recognized that it is not possible to fill the whole DDRAM with Data. 256 MB r complety holden free by the system, regardless how hard i punished the system. Maybe there is a way to play around with the shared system memory to gain some extra performance in games or applications or just to avoid that the system locks usefull memory.
EDIT: Found this: GraphicsMemory.doc
