1 Rename or delete the inte * * * directory under your World of Warcraft installation directory, and then transfer all files under your WTF and WDB directories to other folders. When you rerun World of Warcraft, these files will be rebuilt according to the default values. 2 Create a game shortcut for wow.exe, then right-click the shortcut, select Properties, and add -opengl to pay attention to the space after the target item. For example: "d: \ world of war craft \ wow.exe"-OpenGL, or you can use the -- windowed parameter to run in the window mode at the same time, as long as there is a space between the two parameters. 3 Check the status of the hard disk. Use the ScanDisk/Defrag page command in the running window to check whether your disk has too many fragments or errors. If you use a hard disk larger than 127GB, please make sure that you have applied the latest patch from Microsoft. World of Warcraft will run at the maximum state of your hardware, so if you overclock your hardware, please jump back to the normal working frequency.
