Hi, the AMD ReLive game capture overlay seems to have an issue in DayZ. It does not function unless you change the resolution from one to another and then back to your original. At this point the overlay works and you can begin streaming. However if you alt-tab or minimize DayZ the streaming stops and it breaks again. So you have to change the resolutions to get the overlay back up.
I attempted to solve the issue by for example removing steam overlay and other things but it has no effect. The issue is quite annoying and makes streaming or recording very tedious.
