The first thing I have to say is: Please read the YanC documentation that is included in the package you have downloaded.
As you can see, antialiasing, anisotropic texture filtering and vsync are environment variables that can't be saved in the XF86Config.
--> "This option will not be stored in the XF86Config. An environment variable that will only be valid for the application entered in the "Run program" field will be set. "
Please enter the program which you want to start with the customized settings for antialiasing, anisotropic texture filtering and vertical synchronization in the "Run program" field. To launch the program please either press the input key or the "Run with customized settings" button.
