I play 2 v 2 with a friend and 2 computers. After time goes by the game is unplayable your servers are so slow it take forever to do anything. What can we do about this can we just play over the net with our two computers? Because your servers are not cutting it.
You can always create a local game. Then the server will run on your own computer. You'll need 8GB of RAM or more though. Also, I am not sure if that would help. Servers usually slow down when you have lots and lots of units as Uber didn't implement a unit limit for futureproofing reasons.
