Sorry, maybe searched to fast for a good reply but in general that is maybe the point:
Or another shorty:
Quality is better than quantity.
What do you get from millions of planets if you are either alone on them or every planet looks the same?
We will get star systems in Empyrion soon but No Mans Sky and other “big big” games showed how to perfectly fail with these approaches.
But that goes #Off-Topic here.
Regarding the performance: check with patch 7.1 again and let us know please.
Thanks.
