Arensnuphra That seems about right to me. The terror, being nearly twice the price cap in BH, and having more crew-per-credit than usual, is basically the most intensive ship in the library right now. I just recreated that scenario myself, and got a very similar amount of lag.
As far as lessening the lag goes, turning off fancy particles helps some people, lowering the game speed (Which speedset allows you to do to a much larger extent) will always help, and if need be, Cosmofine should allow you to run a lot more stuff at the same time, at the cost of some physics accuracy
