Where does this version save the settings?! How can I achieve the "out-of-the-box" experience where the game explains to me about the enabled accessibility options and gives me a choice to disable them all at once, etc.? I searched the game dir, the appdata folders, programdata, registry... I just can't find where the options are saved. Help?

I hope this puts you in the right direction:

"Heads up for anyone on PC who wants to reset the settings: Delete the kexengine.cfg file found in your "C:\Users\XXXXXXX\Saved Games\Nightdive Studios\DOOM" folder. This should set everything to default (display, audio, controls, etc.). "

@borsdy, thank you. You're a life saver! :)
