Internal Graphics
The setting enables/ disables the internal graphics.
GTT Size
The Graphics Translation Table (GTT) is a Translation Lookaside Buffer
(TLB) used to map the virtual memory space of the graphics aperture to
that of the physical address space. At less 1MB for Intel Smart 2D Display
Technology direct access to the pre-allocated memory space is necessary.
Aperture Size
Aperture memory will not be used until on-board memory is running low. That
means it will usually not impact gaming performance because developers
are trying hard to not exceed the on-board memory limits. However most
games requiring more and more texture memory supported. A good number
seems to be 256MB Aperture Size for all.
