I have already mentioned this in another part of the forum and noticed that it is not a general problem. And it had happened to me exactly the same when I went from the stable version 1.5.7 to the 1.5.8 beta. Now, when going from the stable version to the new version,1. 5.9,I don't even know if it's beta or not ..., the performance problems reappeared. As soon as I installed it, I noticed when going to the settings, that everything had gone down to medium and low, I always had it high and very high, and when I started playing there was a huge lag on the map, it looked like a frame-by-frame advance. Did anyone else have this problem? I've heard theories of mining and all that.
