didnt read all answers, maybe someone said this allready i had bad fps too for me it helped to start arma with this: G:\ArmAOA\Expansion\beta\arma2oa.exe -beta=Expansion\beta;Expansion\beta\Expansion -mod=G:\armf;Expansion;@DayZ -nosplash -world=empty -winxp -cpuCount=4 most fps i got with -winxp edit: be sure u have the latest beta patch installed http://www.arma2.com/beta-patch.php and change "HDRPrecision=32" in ur ArmA2OA.cfg normally in folder: C:\Users\"username"\Documents\ArmA 2 if nothing helps maybe ur Radeon HD 5700 is too weak and the server ur playing on has something to do with ur FPS too, on some server i get only 30 on others 60 most time (vsync on) only in towns it goes down to 40 my system is: amd phenom 2 x4 @ 2.8GHz radeon HD 6870 1GB 4GB DDR800 RAM
