I hoped you turned off camera movements like head bob in the options menu in the game. This will without doubt give you a headache as it does it to me. Every time you walk the screen will slightly move, and if you are sensitive to that stuff you will get a migraine. The game is so much better and smoother after turning off that option.
Cyberpunk also was giving me migraines and then I turned off those camera animations and migraines gone.
EDIT: of course you may need to increase your FOV to at least 90.
Several tips have come to light that I hadn't tried so I'm going to give the game another shot. Didn't see the setting for head-bob, that sounds like a definite trigger. FOV was the first thing I adjusted. Thank you
