I am playing Overwatch on this setup:
CPU: AMD Ryzen 7 2700x
GPU: Gigabyte Windforce 8G RTX 2070
Mobo: AsRock Fatal1ty Gaming k4 B450
And the past few days I have been playing it with no problems at all. Today (12/01/2019) my game crashed saying “Your rendering device has been lost”. I have searched on the forums and tried everything, from redownloading softwares, re-updating Windows 10, Making Sysmain (which is Superfetch) running. I don’t have anything overclocked. I remember that at least that a few days ago I had a Windows update.
