Got to agree with most comments here. I've had problems with Supercruise in highly populated systems, either with excessive FCs or planets (one system down by the Orion Nebula had 36 bodies). And it gets worse when visiting Engineers. Left my FC in the black and took a trip to engage with Chloe Sedesi in Shenwe. Game crashed a few times, both entering and exiting the system. And on the occasion I was able to play, the game was lagging badly. Permit locking the Engineer systems seems to be the only acceptable option at this time to allow everyone to play comfortably. And Deciat permit can be a reward from the initial mission so it is open to players but stops FCs parking up.
