I had some pretty similar performance issues before 0.13, however the first few hours of playing 0.13 went perfectly fine for me. About 1 hour ago it was still working fine, but now I can't move more than a few seconds without my game freezing or anything of the likes. I have not experienced any proper crashes with this either so it is most likely different to the other reports about similar issues. (This is less of a bug report and more of a cry for help)
