Whenever i am in multiplayer server in an area with a few players and not shooting or using radar my game is fine. When more players are around doing things my game lags a lot and crashes. Sometimes it just crashes randomly on multiplayer and im not sure why. It seems the more entities i am around the laggier the game is. Could someone please tell me why this is and how it could be fixed? (I have FC3 installed)
