Hi Everyone
I've got the game and it has not crashed for me once. I've been playing for three days straight and my laptop is not as powerful as some of your pcs.
Try this:
Turn off Autosave frequency (slide it all the way to the left)
Turn off Shadow detail
Turn off Night&Day Cycle
Turn off Weather
Reduce Shaders to Low
I'm reading that alot of you guys can only play for like 10 mins then it exists to desktop. Well for 90% of you the reason that happens is because the autosave fails and the PC doesn't what to and so it exits to desktop or freezes. I find this to be the most likely problem because the default autosave frequency is - every 10 mins.
I really feel for you guys and it must suck that you put you bucks and effort for something that lets you down.
Hope this helps.
