[multiplayer lag] I would like to lower the number of pedestrians and cars on the road

[Yourebuying]

What files do/can I edit to accomplish this? I would like to lower the number of random cars and pedestrians so that the game's fragile netcode doesn't have a stroke every time I try to play the game with too much happening on screen. I already removed the light tracers from the grenades and that helped a lot, but I feel like I could get away with lowering the number of cars and pedestrians for a better multiplayer experience.
