A problem with the game, please help. (Saints Row 4)

PS3
The problem is that I recently bought Saints Row 4 on a sale in the Play Station Store I
go into the game and start playing
But the game starts to lag
And I just have to turn off the Play Station
I don’t know what to do
The sound of the game is playing, but the game is frozen Gamepad
buttons are not answer
Hangs on the moment when I approach the rocket
Or on it
In general, I need help with this game.
