This trick lets you use your existing Battlefield 4 key bindings and graphics settings with Battlefield 1

Don't waste any time sorting out your graphics settings and control mappings.

If you're among the lucky few who have access to the Battlefield 1 beta now, or if you're waiting patiently for tomorrow's open beta launch, you may want to copy over your settings from Battlefield 4 to save yourself some time in-game.

If you have Battlefield 4 installed, you can simply navigate to your Documents folder > Battlefield 4 > Settings. Under Settings, you're going to find a file called 'PROFSAVE_profile', this is the one we need.

As Reddit user Wiidesire notes, all you need to do now is copy that file into the same folder for Battlefield 1, which you can also find under Documents > Battlefield 1. But before you do that, you need to run Battlefield 1 at least once to get it to create these folders.

The 'PROFSAVE_profile' contains many of your settings, including all graphics options as well as controller and keyboard/mouse bindings. Even sensitivity sliders and other gameplay options are available.

It wouldn't hurt to take a look at it in-game the next time you launch it, though, just to be sure. You wouldn't want your soldier to go prone when you wanted to crouch, or whatever.
