I play arma 2 just fine with evrythin goin on around me, but opperation arrowhead is different story + dayz, in CITYS my FPS as low as 20, but outside im ok, like serious stan says it can vary, im playin on an old rig 5/6 yo now, its an intell E4300 1.8 core 2, 4g ram, ATI HD 4670, i play with med settings sort of tweaked, out in the wild i get around 45fps, i kno its my cpu that is the bottleneck (or at least i thk so) u can only try it :) gl
