Changing DirectDraw
®
support
AVWorks supports DirectDraw, a standard that allows direct manipulation of
video display memory, hardware blitting, hardware overlays and page flipping
without the intervention of the Graphical Device Interface ( GDI). This can
result in smoother animation and improvement in the performance of display-
intensive software.
However, if your machine has a software cursor or pointer shadow enabled, or
if your video driver does not support DirectDraw, you may experience a flicker
in your mouse cursor when over the title bar of the Viewer.
You can either disable the software cursor or pointer shadow, load a new
driver for your video card or disable DirectDraw.
