The amount of video memory your computer has is dependent on the amount of pre-allocated memory set for your system plus the Dynamic Video Memory Technology (DVMT). DVMT dynamically allocates system memory for use as video memory creating the most efficient use of available resources for maximum 2D/3D graphics performance.
Many graphic-intensive applications (especially games), require a minimum amount of video memory in order to run correctly (or even to run). Video memory is allocated based on the amount requested by the operating system. When the memory is no longer required, it is returned to the operating system for use by other applications or system functions.
DVMT allocates memory based on system needs. Some newer systems have an option in the system BIOS that adjusts the amount of memory available for DVMT. Memory can be allocated up to the maximum limit set by the graphics driver. The maximum limit of video memory allocated by DVMT depends on your specific Intel chipset and the version of the graphics driver installed. Specific information for each integrated graphics chipset can be found via the links below.
