Wait for Vblank lets you determine whether the OpenGL driver will attempt to synchronize screen
updates to the vertical blanking interval. Smooth animation of 3D applications can be achieved by
rendering (drawing) 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.
Visible “tearing” can occur if Wait for VBlank is not selected. Disabling this option gives the highest
rendering frame rates of double buffered applications. You should disable this option, for instance,
when running benchmarks.
Stereo View Support can be enabled (checked) and disabled (unchecked). This option provides control
over the export of stereo capable OpenGL pixel formats. You should enable this option when there is
a requirement to run OpenGL applications that require stereo support, since additional graphics
memory resources are consumed when stereo is enabled. The stereo support provided is quad
buffered and frame interleaved. You must restart your system for a change to this setting to take
effect. For additional information, see Configuring your Oxygen GVX210 Card for Stereo View on
page 23.
Enable 3D Textures activates OpenGL driver support for both 3D textures and Multiple Textures as
used by applications such as Quake 2/3. Enabling this option may affect the Geometry acceleration
performance.
