Apparently they have hidden settings which you can set by making a textfile called BC.cfg in the BC.exe directory and then putting in lines such as:

set playVideos 0 - This will skip all videos in the game, if for any reason your machine is having trouble playing them due to video codecs, etc.

set clickHoldToMove 1 - This enables the experimental click and hold to move function, so players with a mouse can hold left click to move in that direction. Right click will also interact with objects.

set rumbleEnabled 0 - This will disable rumble on your controller.

set showInteractOutline 0 - This will disable the interaction selection outline in dungeons.

set showCombatOutline 0 - This will disable the combat target selection outline.

set immediateScreenFreeze 1 - This will make pause menus/the book immediately gray out the background instead of doing so gradually, if this is causing performance issues on your machine.
