I've noticed the same thing I think. My system is rock solid stable, I never have the issues I see posted in these threads and all my games work without issue using 1080TI SLI. Except recently Deep Rock Galactic updated their UE4 engine. I went from 50 hours no issues to every second game crashing. It wasn't a BSOD -- the game just freezes, and alt-tabbing doesn't remove the game displaying. The only other element to change at about the same time was upgrading to the latest Nvidia drivers (starting wit the version before these - first 4.19 version? Can't remember). Then I tried out Mutant: Road to Eden last night. Playing through the first level, 10 minutes in it freezes and game locks up -- exact same issue as Deep Rock Galactic. Lo and behold, it's also UE4. All other games no problems. And just a quick note -- it's not SLI as it's not being used in either game, both games are using single card. Is it UE4 or the last couple of drivers? I've never had a need to rollback, but if it's the drivers, maybe there's a first time for everything @ManuelG -- is this a known issue?
