I tend to try to play "Epic" games against the AI when I play RTSs. Ill pit myself against 3 or more of them just for yucks and love a game that takes 2+ hours. That said, I can pretty much expect that in every game of PA I play, the game will have a massive slowdown and framerate drop (1fps is not uncommon) due to one or more of the ai opponents going apesh!t with mass uncontrollable unit production. It doesnt even matter whether or not I have any units on world (its usually worse if I dont). It seems like the ai's that have this issue will have gotten their armies "stuck". Its pretty common when that ai's central base area has a combination of drivable and undrivable (water, mountains, etc) terrain. It looks like the ai is trying to centralize his forces before sending them out for an attack but with a mix of terrain at the heart of his base, the land units just logjam in the drivable areas constantly pushing against each other ... by the thousands ... yes thousands... sometimes it looks like 10s of thousands. Armies look like a tentacled monster that just keeps growing, filling the mouths of all nearby ai factories and trashing my framerate. I'll get a screenshot next game I play. For your reference I have 2 quadcore i7 cpus (8 cores total), 32gb ram, a sata3 Ssd, and a gtx 680 (4gb vram). My computer should be more than enough to deal with PA. My internet connection averages about 75Mbps down and 30Mbps up.
So what im gathering out of this is that either PA is soaking up 30mbps or i am running out of vram. Thank you Ryan
