depends on whch servers you connecting to,
Some game servers will always give you high pings,
One way is if your using either Roger wilco or teamspeak is to turn them off,
Also try to connect to servers that arent to busy or in some games make your own.
Maybe if you have other programs using your internet connection try turning them off.
But in the end as long as your not lagging out or not lagging, i wouldnt worry to much about your ping.
