No, not when alt tabbing. Either it occurs directly after starting the game or a little later when I switch server. Alt tabbing does not effect the gamma setting on my system. I have already deleted and updated my graphic driver (GTX 960), no effect.

Central European "prime time" (UTC+1) is the time between 5 p.m. and 10 p.m.

Hello Geez,
I deleted the contents as you said and it worked fine so far. I had no more crashes while playing DayZ 32 Bit Version (in total about 5 hours playtime).

Same here. I switched to Windows 10 64 Bit two days before, and now I have the same issue. Game crash while playing or game crash while exiting game. I did not have the issue with Win 8.1 64 bit.

Hello, it only occurs when there are multiple dead zombies lying in the entrance of police station, all the remaining alive zombies glitch into the basement or "fly" over dead bodies.

Ok, here you are. I hope this helps:

I have tried to upload my crash dumps, but I get failure message while uploading. I made ZIP file ( 27 mb ), I tried to split it, but it does not work. How can I upload the file?

Edit: Server is completely down now.

Edit: Logged onto last server, where I died in the truck. I found the truck at the end of the airfield and my old character was sitting in truck. I got into truck as passenger but could not do any action. I had to log off again.
