Well at some point I seem to have aquired an odd display issue. In normal gameplay I have that look like when you're in power armour HUD or looking through a recon scope, you know all sepia, crushed contrast and fuzzy edges. I took some Adictol thinking I'd overdone the Psycho ("F-king kill!") or too much of Tommy Tinker's chems, but it looks the same. I tried an earlier save and it was fine, but I've levelled up quite a bit and don't want to do the Railroad quests again (I was just trying to get the ballistic mesh craft ability anyway - which I still haven't managed after countless PAM and TT side quests).

Anyway, was just wondering if this was an issue with the update or if there's some game play that could cause this (like taking certain drugs or perks)?

No ideas what's causing this?
