Well, I know that in FaS, when I turn down the graphic power, for the sake of better FPS, there's one set up function that I don't turn down/off anymore, because without it, it turns off the smoke and explosion effects. Also, notably this function's option in the menu was not showing, I could only turn it on/off via the "low, medium, high" graphic display options on the right of the video options menu. I could tell because when I manually turn everything as low as possible, it ends at somewhere in the 120's, but when i chose the "low" option on the side, it then turned into about a 133%....
so that MIGHT have something to do with ashleyheshir's problem :/ just a thought
----oh, but I never got "script error" when smoke and explosions were turned off.... so, probably a different ordeal here, sorry
