Just Registered to say I have the same problem as well,thought my graphics card to blame because it’s being old.
Same symptoms as above, Overhead map freezing and a few seconds later my company appears where it should be
if there was no freeze, Don’t register key clicks (Pause, escape etc.).
Seems like a performance issue. DxDiag attached.
Game is awesome but I cannot enjoy it at the moment due to this problem.
