DVMT
Dynamic Video Memory Technology (DVMT) - Allows you to select
the amount of system memory allocated to the integrated graphics
device (IGD) video.
Intel Dynamic Video Memory Technology 3.0 (DVMT 3.0) allows
additional memory to be allocated for graphics usage based on
application need. Once the application is closed, the memory that
was allocated for graphics usage is then released and made
available for system use.
The options available may vary by board.
For information on DVMT, refer to the Intel® Graphics Media
Accelerator 900 White Paper at
