4.3.6 OpenGL Acceleration
OpenGL functionality is available with the OpenGL display driver provided on the
Microsoft Windows NT CD. In addition to this generic OpenGL display driver, you have
access to an optimized OpenGL display driver from Compaq (pbxgdacogl.dll). This
display driver maximizes the performance of applications that are written with OpenGL,
and supports OpenGL Version 1.1 and the OpenGL Utility Library (GLU) Version 1.2.
The pbxgdacogl.dll file is located in the %SystemRoot%\system32 directory, where
“%SystemRoot%” is the environment variable defining the path of the system root
directory; for example, D:\winnt40. For more information on using the Compaq OpenGL
display drivers with the PowerStorm 300 AGP and 300/350 PCI graphics controller, see
Section 5.3.
