I have an RTX 2070 from Gigabyte (Gaming OC 8 G).
At the moment I am not yet using 417.71 but 417.35, if I am correct. I am a little hesitant on getting the latest drivers installed because my crashes already seem to happen less often than for some in this thread. My crashes, if they happen are once a day (It has never happened to me twice per day) which could be in the first match but it usually happens after a few hours of play, if it happens at all. The crashes seem to happen at any time during QP matches. At least for me it doesn’t seem to happen solely when there is a lot going on. It can even happen when it is just me and one other person on screen.
Update: I haven’t crashed yet with the OverwatchTest method.
