I had the same problem. For me it was the field of view which had to be changed. You can give it a try: http://dayzmod.com/forum/index.php?/topic/31609-ultimate-fov-field-of-view-guide-for-arma-2-and-dayz-from-dayzpvpcom/ Another thing you can try is to set the shading quality to zero: go to My Documents/ArmA 2, open up the file called "<profilename>.ArmA2OAProfile" Change these lines to the following: shadingQuality=0
