Starbound suffers from a very bad optimization, you can notice in the video, that the game lags occasionally. Most of the time these lags happen during preset missions where you fight bosses.

Right before the final boss, you have to defeat Asra Nox again. She's the same as before, only this time you can kill her much quicker. Since i used the checkpoint, that part was skipped.
