Hello there, buddy. This is common sense but I'll explain it to you. The 5 FPS you see is the rate at which the world is simulated (also known as tick rate). Yes, your client can run well but your server's tick rate matters a LOT in player interactions. The shitty tickrate is part of the reason why you get SECONDS of delay in DayZ. This is the reason why people shoot at each other and wonder why nothing happens. Our server is running at 1-8 FPS with barely any players on it and the CPU is constantly maxed. This is a joke.
