Post was deleted because I can't post IMGur links apparently, so I'll do this again quickly.
The game's UI/HUD is bugged and won't show the cursor or any text-based selections (example; main menu is blank save for a transparent green box).
In-game the display is clearly glitchy and is showing two of my characters along with strange lighting issues. Menu/Pip-Boy are similarly bugged. In short, game's pretty unplayable.
Have been playing FO4 on a solid rig since release. I've only modified the .ini files as necessary to make mods run, and the mods I've been running have been simple texture replacers without issue. I've deleted these and uninstalled the mods to no avail.
I'd post the image links as it's hard to explain the screen, but I can't post links, apparently. I can try to PM them or something. Regardless, any help would be much appreciated. Thanks.
EDIT: Still unsolved. See moderator post below for pics.
