So I got a not really good laptop, but it runs games well. But terraria is a problem for it. The game lags a lot. I've read other posts, but none of them helped me to fix the problem. I assume the problem is achievements, becuase the lag only happens when walking, when jumping,flying or doing other stuff it will not lag. So I want to know, how do I disable the achievement tracking, because there is a achevement which requires me to walk a lot of distance, so it is calculating when I walk, but how could quickly get that achievement, or disable it?
