I have Overwatch installed on my personal PC. I'm playing it trough a friend's battlenet account. I'll soon buy a copy for myself and simply login in battlenet and play on the same installation on my PC. Will the settings I have for graphics, sensitivity and different heroes be saved for me, on the new account, or will they be saved on my friend's account and I'll get some default settings ?
The settings are installation specific. They are stored in
C:\Users\[username]\Documents\Overwatch\Settings\Overwatch\ so your best bet would be to copy the files in that location from your friend's computer to the same location on yours.
Unfortunately, gameplay settings like sensitivity and keybindings are account specific and loaded from the Blizzard servers when you login. You cannot copy them from an account to another, you have to re-setup everything by hand.
Graphics settings are installation specific and are located in
