Hi, I have a similar issue, the game freezes then I'm oblige to alt-tab to window7 and see this message "Dayz has stopped working". I am not sure if it happens only when my computer seems to be overhelmed (entering in a city w/ other players on screen for example) but I'm trying to get a step-by-step game configuration in order to avoid this. Still working on it, but I got some hope last night, no crashes ! I am waiting to see if it will worked fine before making any other cfg modification. Tell me if you find out what is going on your computer. my specs : motherboard : msi Z77A-G41 proc : i3 3230 ram : 4go ddr3 kingstone hyperx 1600mhz gpu : msi gtx 660 2go twinfroze hardrive : seagate sata 1T 7200rpm
