So, i bought Arma 2 couple of months ago and i'm having little problem. When i start playing DayZ everything are smoothy but then after about 10-20 minutes the lag starts. Lag will take about 5 minutes and starts again about 5 minutes after. I have lag only in DayZ but not in Arma 2 or Arma 2 OA. My system specs are: - Windows 7 - Processor Intel® Core i3-370M processor - RAM 4GB - 64 bit I have Nvidia Geforce Experience - Nvidia Geforce GT 420M 1GB VRAM Sorry about my english. And i'm not good telling system specs etc but here are all what i can do. Thanks for help. :)
