Having issues here as well. Also after the game crashes, I can't even start it back up without completely restarting Origin. Also Tomb Raider was having issues over on Steam. Just a bad week for game launches. I knew it wasn't my hardware but I was starting to think maybe it was Windows 8, since it has caused so many instability issues with my programs.
