I have a problem with extremely slow ship movement playing on Insane map with 8 AI opponents – no pirates. I own some 62 colonies and have a lot of ships on the map. When I want to execute at movement the game stops a few seconds and start to move the ship in one or two steps each taking some time. No smooth movement. It helps to zoom in close but not much. If I switch to the next 'Idle Ship" while first ship is moving, the game hangs while the first ship stutters towards its destination. I noticed that my CPU works hard all the time even if not action is taking place in the game.
Game takes up some 9.5 GB of RAM.
Intel i7 3770K, 16 GB RAM, Nvidia GTX 750 TI
What can I do?
