These Standard Features and associated settings are
available for adjustment.
Wait for monitor
sync
Sometimes called Wait for Vsync, this option controls
whether or not buffer swaps and other activities should
be synchronized to the display’s Vertical Synchronization
or Vertical Retrace Signal and blanking period, during
which the display blanks as it retraces its way from the
bottom right to the upper left corner of the screen.
Setting options include:
By App (default) – Select By App if you want the
Wait for monitor sync
setting to change on
application requests. If Vsync OFF is requested, the
back buffer is flipped without waiting for vertical
retrace. If the application requests VSync ON, then
the back buffer is flipped while in vertical retrace.
ON – Select ON to always force a wait for monitor
sync. This option will reduce “tearing” artifacts.
Synchronizing with the vertical retrace constrains the
frame rate so that it does not exceed the refresh
rate.
OFF – Select OFF to allow buffer swaps to be
processed without waiting for vertical
synchronization. When a buffer flip occurs at a
different time than during the vertical blanking period,
visual artifacts, often described as “tearing” or
“shearing” may be apparent. Note that while visual
artifacts will probably occur with this setting, the
frame rate may increase.
Anisotropic
filtering
Anisotropic (which means non-uniform shape) filtering is
a filtering technique more advanced than trilinear, which
is useful for quadrilateral shaped and angled areas of a
texture image. A shaper image is accomplished by
interpolating and filtering multiple samples from one or
