Starfield PC crash fix!!
I've read a lot of posts about people crashing on PC, and sadly, I was one of them. I tried everything mentioned by others, but nothing fixed it for me. The drivers were up-to-date, the framerate was capped at 60, and so on...until I looked in the Windows event log.
It seems that Starfield somehow profits from a bigger page file size. If you haven't set it to "automatically manage page file size" (or at least have it set manually to a bigger size) in system properties -> advanced -> virtual memory, the game will constantly crash, at least for me.
Since then, I've played for around 3 hours without any crashes, before that, they were constant.
Edit: played over 20hrs with only one crash.
