With the success of the TV Series, Bethesda have taken the time to update Fallout 4 with next-gen features for consoles, fixed some bugs, and finally got this amazing game "Steam Deck Verified & Certified", but unfortunately this seems to be at the expense of disabling the original PC launcher, which means that you can't now access the games graphics settings...
In this tutorial video I show you how to re-enable and re-activate the launcher (is un-disable a word?) so that you can change the graphics settings should you wish, but hopefully Bethesda will patch this in anyways before too long.
Thanks, Rob.
