Dynamic Video Memory Technology (DVMT) - How much video memory do I have?

Many graphic-intensive applications (especially games) require a minimum amount of video memory in order to operate correctly (or even to run at all). So how much video memory does an Intel® chipset-based system with "integrated graphics" have? The answer: it depends.

The amount of video memory is dependent upon the amount of pre-allocated memory set for your system plus something called Dynamic Video Memory Technology (DVMT). DVMT, as its name implies, dynamically allocates system memory for use as video memory to ensure the most efficient use of available resources for maximum 2D/3D graphics performance.

The amount of video memory allocated depends upon 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 to adjust 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.
