Oh my gosh...
Just alt enter in game and manage with windows manually by pulling it's window in any side you want and make this kind of 2 windows.
Yea i can do that dude, thats not a problem, but what happens when you do that is you still get lag on one (like if they were both open full) this apparently makes them think they are both open (both on top) at the same ti,me
alt+x > options > Untick Decrease Background Performance ?
I wish I had much RAM and iProc GHz and cores
But, everything good in its season
lol... its not that much big of a deal... i can run with 4gb ram 7-8 clients with phenom II x2 560t... i could run more earlier cuz i had 8 gb ram but one stick died... so im stuck with 4 atm
hint
lower resoulution means lower ram usage
