Help me ! :)

Hi guys so basically i want to run 3 barbarians on my isboxer i can run 3 but the other two seem to lag behind

my pc specs are
Windows 7
8gb ripjaw Ram
AMD Phenom II X4 850 processor 3.3ghz
AMD Radeon Hd 6670 graphics card

I have set it up so the main uses 2 cores and the other 2 use 1 each i have also set it to 60 front and 20 background fps any help would be appreciated

I tried 4-boxing D3 for a weekend but didn't enjoy the desynchronisation issues you get all the time with no /follow.

However, I did find the 'followers' lagged far less when I swapped from 60/15 to 30/30, so all my clients had the same FPS all the time - try it, it might help.

Thank you very much appreciate your post ill try it now
