Sorry.. i had posted this is isboxer forums and Lax gave me some tips.. BUT what i found out is it was not my PC.. it was the toon. I was playing Ironman..Hawkeye, Storm and Scarlet Witch..the scarlet witch and hawkeye both would lag behind ( run slower ). I made a new team of ironman and 4 ( added a 5th account ) Storms and they stay together.

I do have heavy lag/low fps in heavy combat areas with lots of mobs and players around, which can cause the team to separate at times. I have all settings on lowest settings. All windows are 1920x1080. In isboxer i have tried round robin and all cpus for all windows.
