And not to forget the radar issue (though worked around in mods) or the chronometer for those that like their TDC manual.
Oh, and repeating missions.
And could anyone turn the IJN sonar operators onto some cool addictive music. My engines and creaking noises can't be all that exciting now, can it? I mean, I try to be kind and keep the noise down, but will they return the favour?
Bastards
As for stuttering time compression: It's the nature of the beast, if you don't like it upgrade your CPU, or don't go over the "stutter" treshold (not applicable in the vicinity of multiple contacts, like say a convoy. A dead giveaway BTW if something interesting is close by. If it stutters, something of a target rich enviroment can be found for those that care to look). A lot of tedious and constant computations happen at TC, the stutters are just your computers way of saying it's enough already.
