Report to the application that it should use this version of the OpenGL API with your Matrox product. Some applications work better with a version of the OpenGL API older than what's currently installed on your system. While this is enabled, anytime the application requests to know what version of the OpenGL API your Matrox product complies with, PowerDesk provides the version number specified here.
