I am having trouble figuring out how to run the timedemo in Hexen II for both the GL and non-GL versions with patch 1.11. Originally, I installed Hexen II from CD, which is version 1.03. When I load the game, at the command console, I type timedemo demo1 and the timedemo runs just fine and displays an average frame rate. However, after I patch the game to versions 1.09, 1.11, or 1.15, I receive an error after typing the above command. The error is: error: couldn't open. Is a new command needed to run the timedemo with these patches?
