To reduce your lags and ping on the game you can use :
Pingzapper
Noping
Both programs reduce your ping by alot.
My own experience with pingzapper was that it improved my ping from original 390 to 130 after using the program.
Pingzapper has a trial you can test, for "no ping" it has trial only in a few countries
There are several other good programs but the ones I listed are programs me or ppl I know successfully used
