if you want to have a good ping you need to play in your server....for example if your in eroupe and all those areas play in UK servers....if your in North america play in delta or alpha....(I play in delta I get like 80 ping)
Second close every thing on your computer that you do not need because It slows down the internet....
Third is if you have a strong computer or not....if you have a i7 prosseser and 12 GB ram that is good.....I have 2 GB ram (I need to get more ram....lo)
