Configuring Key ForceWare Graphics Driver Features
Vertical Sync
Vertical Sync settings specify how vertical synchronization is handled in OpenGL
applications.
•
Off
keeps vertical synchronization disabled unless an application specifically
requests otherwise.
•
On
keeps vertical synchronization enabled unless an application specifically
requests otherwise.
Vertical Sync
Click the list to specify how vertical sync is handled in OpenGL.
•
Always off
always disables vertical sync in OpenGL applications.
•
Off by default
keeps vertical sync disabled unless an application specifically
requests that it be enabled.
On by default
keeps vertical sync enabled unless an application specifically requests
that it be disabled.
Unified back/depth buffer
Note that this setting is
on
by default allowing the OpenGL driver to allocate one
back buffer and one depth buffer at the same resolution of the display. When this
setting is enabled, OpenGL applications that create multiple windows use video
memory more efficiently and show improved performance.
When this setting is off
, the OpenGL driver allocates a back buffer and depth buffer for
every window created by an OpenGL application.
Early z test
Enabling this option causes a z-test to be performed earlier in the graphics pipeline,
which can improve the performance especially of shaded rendering when items are
often behind other items that were already drawn.
Note:
This settings is “disabled” by default for most application because enabling
this setting generally hurts application performance for wireframe rendering.
