My video needs to be set to balanced, or else it has stuttering issues. So I can only change it on a single program basis. By default, anti-aliasing is on. The game getting a problem from this is Halo, but I can't change anti-aliasing to off in the control panel. There is simply no "off" option for anti-aliasing mode. There is only Use Global Setting, Application-controlled (still causes crash), and Enhance the Application Setting. There's no off, and that's the only setting it will accept.
