3D Sync
Your XCLAIM VR graphics accelerator provides superior
3D performance by performing many tasks in offscreen
memory including graphic rendering. Depending on the
3D scene, the refresh rate of your computer monitor, and
the game or application, you may notice some slight
horizontal ßickering or ÒtearingÓ. This ßicker is caused by
the different rates at which the display performs a
complete screen redraw, and when the XCLAIM VR
moves images located in offscreen memory to the display
buffer. Synchronizing the redraw and the write to the
display buffer provides a ßicker-free 3D window.
¥
On (Synchronize with vertical refresh) - Provides a
ßicker-free 3D window. The display is synchronized
with the vertical refresh, so there isnÕt any ßickering
or ÒtearingÓ in the 3D window.
¥ Off (Do not synchronize with vertical refresh) -
Provides a boost in performance, but in some games
and applications it can introduce ßickering or
ÒtearingÓ in the 3D window.
You should experiment with these settings to Þnd the
proper setting for your application.
