Got my 3080Ti FW3 Ultra last night and played my favorite driving sim for 2 hours in VR with my HP Reverb G1. Within seconds of *exiting the game*, (less than 10 I think) I get black screen. All 3 of my monitors went black while I was at my desktop moving my GPUZ window to my main screen. Within a few seconds of that, I get my windows login screen. (Not enough time for a reboot). I log back in and find my carefully curated triple screen wallpapers all out of whack. I decide to try the sim again before doing anything else and VR is messed up. (Everything is HUGE and the menu appears to be touching my nose....re-centering my headset just puts my nose more precisely in the center of the menu)
I rebooted and everything appeared to be back to normal, played for another hour and everything worked fine. Still, I just upgraded from a 3080FE that never had anything like this happen.
I was running stock with the exception of the overclock BIOS for the more aggressive fan curve. And because I know power supplies get blamed for a lot of stuff: My PSU is a Corsair RM1000i and this happened while at my desktop with almost no load.
