I usually play on medium graphic's for everything, unless i really want to get the best view of scenery. As for torrent bugging, i don't know of any bug or malfunction that would result in your being unable to change graphics. In addition, it would seem more likely that if there was a graphics bug, it would not cause you to only be able to use max settings... You just wouldn't be able to see. < At least that's what i would think if i was in your situation.
