I've got ~50 hrs in game.

I've had 1 full crash, and a good handful of NPCs running into walls or levitating through ceilings.

Performance is fine, I guess, but I got the game as part of a promotion while upgrading my graphics card so it had better be. I believe folks who say it runs like dog on hardware that's only a couple years old. It's apparently unplayable if installed on a hard disk instead of an SSD.

All in, it's the smoothest Bethesda launch I've ever seen (I skipped fallout 4, maybe it was better IDK) but that's honestly not saying much. It's way better than cyberpunk was at launch.
