its a combo of f-11/12 and f-9/10 i believe, each sets a parameter and the game will run fine when u find the optimum if that's not it then... ur comp sux! 640k memory lol noob
I first played it when I was 11 and never realy managed to get trough. I oftentimes replayed it later on, sick game. Actualy all old games from acclaim were good (Turok)... oh acclaim :(
