GTA V #5 father and son Mission

I know my GTA V lag because my laptop is normal.

Father/Son is a storyline mission in GTA V. It is the protagonist Michael De Santa’s mission. It also involves Franklin Clinton and Jimmy De Santa.
In this mission, Franklin is seen visiting the De Santa residence to ask Michael if he has a job for him, while Michael is resting on a lounge chair by his swimming pool. Michael invites Franklin to have a beer with him. While they walk towards the car, Michael receives a call from Jimmy, who tells him that his boat has been stolen while he (Jimmy) tried to sell it for some money. Michael and Franklin take Amanda’s car and go after Jimmy.

They drive towards Pacific Bluffs and see the boat on a trailer. They go after it and Franklin jumps onto the boat, having to fight two men on it. Jimmy safely gets into the vehicle while Franklin is still aboard the boat on the trailer. Michael gets closer to the trailer and Franklin jumps back into the car as well.
After the car has taken quite some damage, it slows down and the trio drive to Los Santos Customs. Michael takes a cab after giving Franklin some money to fix Amanda’s car and drop Jimmy home. Franklin drops Jimmy and the car at the De Santa residence and leaves.
