I just changed my old computer into about 4x more efficient one, I have noticed following annoyances: For some reason ships go extremely low speed in tactical combat when you choose option "Animate ship movement in combat". If I take it off, the movement is about 2x faster (still unbelievable slow). If I choose the option "Fast tactical combat", I they move so fast, I can't actually see anything. No movement (I just see the first and Last square of the movement), no firing (occasionally some flash supposed to be a beam weapon) or explosions. This effectively cripples the whole combat. If I choose to watch my fleet battle (no fast tactical combat), I have to wait maybe
AN HOUR for
ONE BATTLE TURN to be watched (if its a big battle).

If I take the "fast tactical combat", I can't see how my ships move and fire in practise and that effectively kills all pleasure of wathing any combats and also I can't therefore tweak my ship strategies for I don't want to wait tens of minutes just to see how one special ship fires.
I believe this has something to do with processor sped, for my old computer could handle it better. Well, I don't know but it should be addressed one way or another.
