Help:Renderer Initialisation Failed
The T:ANE renderer initialisation begins when the game executable (i.e. The Launcher) is started, and continues for some number of seconds. If the initialisation fails for reason an error dialog will be shown when attempting to do anything which requires the renderer (e.g. entering the game environment).
If this error is displayed it indicate a corrupted install, or (much more likely) an incompatibility with your hardware. In some cases, it may be possible to resolve this by adjusting your game settings in the launcher.
When the error is encountered, detailed information is written to the T:ANE log (accessible through the main menu "Developer" options). If the error is displayed again subsequently within the same run, no further entries are written to the T:ANE log.
