Here is the Microsoft webpage for the pattern to follow for the display recovery, ArmA 3 is DX11 game or not ? That is the question !

For myself, i've stopped playing ArmA 3 for now. Waiting to change CPU/MB/RAM/Storage in few week along with a clean & fresh Windows 10 installation, to see if it helps me solving it. But anyway, the game itself should integrate the full display recovery after a TDR.
