I don't have any framerate issues unless something big is happening, and even then it's not bad
also, to whoever was wondering about water the other day
there is water, but it's frozen
if there is liquid water I have yet to find any
edit: I have a 16-minute long video of this whole deal
I'm gonna shorten it and see if I can manage to upload it to youtube
some of it is worth seeing. like my amazing jury-rigged atmospheric flight capable ship which I originally copied and pasted from something from the workshop
which still crashed. I am a complete and utter failure
