My rig Phenom II X6 1100T @ 4ghz- 20-30% usage while playing DayZ SA per core (unparked cores) GTX570 1280mb SOC version by gigabyte, slightly OC´ed by me- 15% usage in town, 20-30% usage in countryside and forests. When I stare to ground or sky GPU usage jumps to 99% (I dont really get it) rest of the rig- 8 gigs corsair ram (some fast pieces, my friend bought them for me to fit into rig), Asus Formula IV Extreme, game is installed on 1tb 7200rpm HDD FPS Town like elektro and berezino are almost unplayable for me (no matter what settings I set low, medium, high) around 20 fps. Countryside and forests are ok (40+ fps, but again no FPS boost when I set the game on low, high etc. only FPS loss when I turn on AA) If I have 30+ fps in cities and 50+ at forests and country... I will be one happy mother fucker
