No, I've had no crashes, no significant bugs and I've played around 25 hours (the kind of platime I very rarely do, in a short space of time). I did end up turning ray tracing off on my pc, because the framerate tanked during one scene, but otherwise, it's been pretty solid.
I was really enthusiastic to play it, loving cyberpunk aesthetics and the Witcher games, but wasn't expecting anything too trancendant. Those 80s sci-fi vibes could carry me through something far more mundane, for sure. I gave up on Mankind Divided twice, after a few hours, for comparison.
