Bought a new computer recently - Pentium i7 -4790 cpu, 16 gb RAM. I thought I'd be able to play ck2 to late game now that I've got a new computer, but I find that with over a thousand living/dead family members, panning across the dyanstic tree gets really slow and glitchy. Is this normal or is there some kind of feature I can tweak (the refresh rate, perhaps? Currently set to my screen 60 hz) to make it better?
