I've had these on and off since Stormblood dropped to be honest. Sometimes it feels like they taper off for a few days, a week, even a month, then Nvidia or the game or Windows updates and it'll pick back up again. It always generates strange things in my event viewer like: The description for Event ID 13 from source nvlddmkm cannot be found, etc and has been near impossible to fix. I was concerned enough six months ago I took the whole rig in to my local tech and let him keep it for three days. He tested my GPU and everything he could think of but, proving how inconsistent the error is, he ran the game for two full days and didn't have one. I brought it home and set it up to a new monitor etc just in case it was something with my peripherals and got the errors in two hours. As of now I'm averaging one every other day at random but its highly disconcerting to feel like you can't relax playing because at any moment the game is just going to lock up and crash. Don't get me started about some of the longer single duties I've had to redo multiple times because the errors started coming in fits and starts.
My friend and I have tried multiple things from the obvious, like redoing all my drivers from scratch, to the obscure like altering settings in internet explorer that supposedly caused other people issues. The only thing I've come to learn from this is that it is somehow specifically linked to FFXIV and apparently I'm not alone.
