Intel GMA X3100 Dynamic Video Memory Technology 4.0 memory?
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. * DVMT White
