This lag is strange cuz I can log in and then all is fine but if I tp to other sim it come this lag. I am a Acientworld fighter with dcs and ura and if I log in and all is fine, but as soon as we start a raid I lag out. I never had this lag before but now its so bad that i cant fight any more. Any know what to do ?? Yooshi
