@puzzlezaddict its gets really laggy or freezy when i play bridgeport but other than that when i play moonlight falls it becomes pretty smooth then freezes out of nowhere. Ive tried to use smth like TSW3 for limit framerates and have tried to put a cap on the amount of FPS used, ive tried to make the sims 3 the highest priority, used NRAAS overwatch and errortrap which have helped the game run smoothly but it still crashes
