a tip for those who dont updade at home.
I update my BF4 at work and then copy the BF4 folder from my laptop to my home PC. But this update and the update before, even if I deleted the dir on my home PC and copied over the updated BF4, the game would still download the entire update, no matter how many times you repair.
So what I did was to open regedit, delete all instances (obviously after making a backup first) of Battlefield 4, and installing the game again from within Origin. It didnt pick up the existing and updated game files right away and started to download again. I simply stopped it and did a repair.
Good deed for the day done, now hide away you 18+ daughters! "whistling:
