Number of DMA Sub Buffers
Each DMA buffer is subdivided into sub-buffers, which are used in conjunction
with an Interrupt DMA mechanism to reduce latency in the system. The number
of sub-buffers can be set here. Setting it to 2 will disable the interrupt mechanism.
Wait For VBlank
Smooth animation of 3D applications can be achieved by rendering to an off-
screen window/desktop sized color buffer and copying or swapping the contents
to the displayable front buffer at the completion of each frame. Enabling this
option prevents tearing of the display by synchronizing the swap of the back
and front buffers to the vertical blank retrace interval of the monitor display.
Leave this option unselected if the highest rendering frame rates of a double
buffered application are desired (i.e., not locked to sub-multiples of the current
display refresh rate).
