I wonder if you are seeing what I saw in Beta, that the Clipper slowed down immensely in turns.
I couldn't work out if it was something I was doing/not doing and switched to another ship an therefore didn't get round to testing it thoroughly to bug report.
It does not behave like it use to do. One thing is comparing to botships.. thats not so easy to compare due to better bots but I compare to how ship behaves on docking. Well I will stop play until this bug is fixed!
