Hi I'm new I've yet to download DayZ mod I have only downloaded the game so far doing the tutorial I am lagging very hard but I am defragging, updating graphics cards, and doing as much as I can I don't know why but I usually lag on steam games but I can run League of Legends on High pretty good but here even on everything low I have trouble.. My CPU is 2.6GHZ and my GPU is a NVIDIA GeForce 9100
