Please let us know if you are still able to reproduce this issue in latest Development build.

To solve your problem we need dxdiag and all files from this folder: "C:\Users\<Name>\AppData\Local\DayZ\"

Can you pack the files in winrar and upload it somewhere please?
When the *.rar will be smaller than 2.097k, you can attach it here.

Thank you.
