Do you maybe have a solution to the smoke from burning vehicles, missile trails and all other sort of smoke in ArmA 3, not suddenly disappearing because of several simultaneously explosions?
Not really thats a game engine issue, about the only way to "fix" that is either a script that does something to add time, or better yet use a mod like this: steamcommunity.com/sharedfiles/filedetails/?id=2904288133 which may or may not work.
