Ever since he tried upgrading the game, he was saying he couldn't do anything about the Direct X version the game uses, so we had to use DgVoodoo to increase game performance on Windows 10 or 11, whereas windows XP and Windows 7 users had no problem with the game. That's because of different Direct X versions among the different operating systems. Well, Windows 10 and 11 have the option to force games to run using older Direct X versions, increasing their performance on newer operating systems!
