Before you ask, yes I have tried reinstalling the game (through steam) and updating my graphics card. Neither fixed this.
Each time I leave a battle or leave the port, my graphics go apeshit, obscuring all of my screen, usually dropping my fps to 0-10 and forcing me to restart the game to fix it. I'd like to know if there's a way to fix it permanently and make sure it never happens.
I'd at least like to know if anyone else has had this problem. Thanks.
