Wtf happened overnight. Yesterday I played for about an hour and game ran great as usual. Today I log on, game starts out windowed, fov set to 60, and settings reset to default. Fixed them to how I had them yesterday and went to an official ffa server. Game was unplayable. Laggy, and it looked I was having an epileptic seizure. Went to another official Ffa server.same thing. Does anyone have any idea what happened and how to fix it. Thanks in advance.
