Hmm -- taking a quick benchmark look at the CPU and GPU your PC's specs aren't all that much lower than mine (though the 4 GB of ram might be a real killer; my usage is sometimes up to 4 GB before I even launch DayZ.) -- but I can still run at a pretty solid 30 FPS. Not perfect, but smooth enough that I haven't lost a gunfight just yet. When tinkering with settings and searching online for solutions, the ones I found that really made a -huge- difference (as in, 10+ FPS boost) were the following: Go into your Users/username/mydocuments/Dayz Open up the file labeled with your player name that does -not- have .vars appended to the end. Using the find function, search for the following terms and change them to the values I've specified: sceneComplexity=90000; viewDistance=3000; shadowZDistance=100; viewDistance=1600; preferredObjectViewDistance=1000; Save that file, then in the same folder open the DayZ.cfg file and alter the following: GPU_MaxFramesAhead=1;GPU_DetectedFramesAhead=1; In all honesty, I am not certain which of the above fixed the problem for me (I'm guessing scene complexity, but really haven't a clue.) And you could always try fudging the numbers down lower to see what works. Nothing... and I do mean -nothing- else seemed to help my FPS. Even dropping all my settings down to low. Though dropping resolution did help a bit, but the game looked like poop so I've insisted on keeping it maxed.
