During Janeway runs I came across quite a few people pulling anywhere between 7 to a full 12 army party with little to no lag. Not being an avid PC gamer my computer can at best pull 3 after which lag starts to set in with every new client. Yet when I see people pull so many I'm always amazed and wonder what kind of rigs they have that can handle so many clients all at once. I'd ask them in-game but they are always in such a rush that I can never get a moment to ask them while on the field so I figured the forums would be a decent place.
tl;dr What specs does a PC have to have to be able to handle at least 10 or a full party of your own alts with some or no lag at all.
