Keybounds problem || Same PC, different accounts

The binds are stored in a settings file, for me its C:\Documents\Respawn\Apex\local\settings.cfg

If you save your settings and take a copy of that file and your partner does the same, you can swap in your respective copy whenever you want to play.

If you want to make it even easier you could write 2 batch scripts to swap to your copy, you would just need to click that before you start playing.
