3D OpenGL® Overrides
ATI Displays can override key 3D graphics options for OpenGL® based
games and applications. Create a profile, a group of settings, that can be
applied on a per program basis. Use OpenGL® Overrides to turn on
OpenGL® functionality when it is not supported by a specific application
or turn off functionality where it is enabled by an application.
