6 hours in and I have only experienced one issue: crash to desktop with no error just after the intro sequence. It didn't happen on second launch and it allowed me to skip cutscenes I had already viewed easily, so that was good. I am not on the most powerful machine and it runs perfectly fine on the high graphics preset, so despite the huge focus on visuals it seems like enough optimization work was done.

Would that generally be enough to fix launch bugs? Genuine question; I almost always buy games when they're over a year old.
