I had one crash in Apex with this driver. Using a 2080.
The game froze and closed. I couldn't see any errors. I have an eventviewer report, which i most likely can't find now, since it was days ago.
Overall it seems as stable or more than 417. Atleast for me.
I haven't played any other games yet, but I think i will try witcher 3 and shadow of the tomb raider later.
