A couple of days ago I was having this common issue: "Display driver has stopped working and has successfully recovered".
I tried everything that was suggested to me by people such as performing a clean installation of drivers, editing the registry and playing on the lowest settings without any luck.
Until I stumbled on this article, I tried Fix #2 and surprisingly I am no longer experiencing that display driver issue.
I'm just sharing this link to help out anyone who might be having this same problem.
