Fixed is a memory allocation method addition to the Unified Memory Architecture (UMA) concept,
wherein a static amount of page-locked graphics memory is allocated during driver initialization.
This fixed amount of memory will provide the user with a guaranteed graphics memory at all
times, and will no longer be available to the OS.
DVMT is an enhancement of the UMA concept, where in the graphics driver allocates memory
as needed for running graphics applications. If a user is not performing any graphics-intensive
operations, most of the DVMT memory can be utilized by the OS for other uses. We recommend
using DVMT setting for better overall system performance.
