Anyone who's turned off cinematic dialogue, preferring first/thirdperson chatting instead knows the bane of their existence - the horrible camera controls when talking to people. There's actually an area on the screen that allows the cursor to be displayed in order to click on dialogue choices, and moving your mouse towards the edges after a certain point then lets you look around again. The problem with this is that A) it only lets you move the camera in either the X or Y axis, but not both at the same time and B) it's so goddamn slow.

After an hour or two messing around with the related dialogue ini settings, I finally found it...go to C:/My Documents/My Games/Fallout4/ and open up Fallout4.ini, then add bUseDialogueCursor=0 to it. If your game is open while doing this, add the line, save the changes then alt-tab back into the game, open up the dev console and punch in refreshini then hit enter. The changes should take effect immediately; try talking to someone and rejoice in the ability to look around like a normal person while talking to someone again.

Do note that since this (somewhat obviously) disables the cursor in dialogue, you'll have to use the number/arrow keys. At this point though this shouldn't really be an issue...especially with the Full Dialogue Interface.

People have been wondering where in the ini to place it - it really doesn't matter, it's entirely up to you - ini files have no sorting feature, you could place this setting at the ass end of the ini, or right at the front of the queue and it would still take effect. Placing it under a section is purely for organisational purposes.
