Same issue with flickering smoke/lighting + flashing, seizure inducing lights. None of the suggestions/fixes in this thread or any other I've found on reddit have worked.

It's in every cutscene, and constantly in the longhouse. Was literally fine a week ago. Now almost unplayable.

Really hope it gets fixed soon.

I've been getting this same issue for several days now as well. On top of constantly flashing lights/shadows/etc that almost certainly pose a seizure risk. Like I'm at a rave or something. It's brutal. Game was perfectly fine just a week ago, but almost unplayable now.

I can't deal with this in every conversation I have.
