**I HAVE THE ANSWER FOR THIS PROBLEM**. I had the same issue, nothing more than the game minimizing, then afterwards my desktop looking like I had zoomed in about 200% and then having to go to processes through the task manager, close out steam and dayZ then restart again. But I figured it out. Try following these steps. I got them from a buddy of mine in PA who is a gaming whiz, and it has since worked. GO TO: Configure (at the very start of the game, before you click play or look for a server) CLICK ON: Video On overall quality select NORMAL Then go to Quality, (not overall quality, just QUALITY) CLICK ON NORMAL NORMAL NORMAL (everything should be normal), even though you want top quality, you pay for it, just select NORMAL Next CLICK ON TEXTURE Make sure the settings are 2048 MB NORMAL NORMAL NORMAL (so in otherwords, the number should be 2048 MB for this, and the rest should be set to NORMAL) **MOST IMPORTANT** CLICK ON RENDERING RESOLUTION *****SELECT 150% OR LOWER******* this was the main thing that stopped my minimizing and shit. I know these directions seem nonsensical at the moment, but they helped me from DayZ minimizing, my character still moving while I scramble to fix my problem, and my character dying. Again, hope this helps. P.S. my buddy said that specs and OS and all that jazz is really meaningless with regard to fixing this game, as it is in Early Alpha, that the steps up above are only one of just a few ways to fix this. Take care and hope this helps.
