Installing the update for Assymetrix 3D FX This update will allow 3D FX to run under Windows 95 with the Matrox Millennium graphics adapter while using its 3D acceleration capabilities. You must have 3D FX already installed from the Superpack CD ROM, version 1.0. If you have version 1.1 of the Superpack CD, you do not need to install this update. This update will not work with any other versions of 3D FX. To install it, simply copy the file TIDAL.DLL to the directory where you have installed 3D FX. This will overwrite the existing TIDAL.DLL file so make sure 3D FX is not running.
