The game seems to work fine in multiplayer for about 40 secconds, then fps drops from arround 30 to 2. If i have mods installed it closes the game at this moment. without mods it stays at 2 fps for abour 30 secconds, then its back to the normal 25-30 fps i get at the start, this repeats every 10 minutes then. (this is on lowest settings with a powerfull pc).
This is with a just recently installed copy of arma3 since i just bought it on steam. {F26454}
