Opted in to the beta patch, loaded up my game (after having made a backup), walked around the corner and started shooting at some raiders...boom, game crashed.

Attempted the same fight a couple of times after that using different approaches, but no dice, game still crashes as soon as I get into the fight.

The same is happening in other places or with other groups of enemies as well.

Praying that this "update" doesnt make it into the release patch...;;

Edit: I noticed that the game keeps setting my texture settings to medium all the time, even when I make the ini files read-only...

Edit2: It is quite possible that this issue is not even related to fights; rather, it seems to me that the game simply crashes after a certain amount of time has passed, which is even worse.
