BF3 always crashes and closes if I open video settings.

Hey, @xJoBoBox make sure that all drivers for windows and your gpu drivers are up to date.

You can also try to do a clean boot to see if there any programs messing with Battlefield 3 and turn off any overlay programs for example Discord or Nvidia experience.

Try running a CCleaner to remove old temp files and cache.

Let me know if this works or not for you. 🙂
