Flashing lights in the game (Call of Duty: Black Ops 3)

Who faced the problem of flashing lights in the game when looking at the light ?. And another question is how to make normal graphics in the split screen mode, but how I play the feeling at low ones. And how to enter zombie mode (pirate). And please, it is inappropriate to write that I had to buy a person, and so I bought a pirate for 800 rubles (besides, there is no place to find it in my city)
