I am on turn 245 and when I move fleets it lags a lot, when I move ships it lags less but still a lot, does this on both my computers, one is
Core I7 3.2GHz
16GB DDR3 Ram
Geforce GTX 960 2GB DDR5 Video Card
WD Black HDD
Windows 10 Pro
My other computer is
Core I7 3.2GHz
12GB DDR3 Ram
Geforce GTX 760 2GB DDR5 Video Card
WD Black HDD
Windows 10 Pro
Both do the same lag but the early game runs perfect, this is also an insane map size with 12 major races and a bunch of minor races.
