Literally, when ever my blood goes low and the screen becomes saturated my eyes feel like they are gonna bleed. Combine that with an un even FPS and I can't even play while it's like this cuz my head starts killing me, I've turned down the brightness but it just delays the on setting headache, starting to think about just killing myself than keep going. I know there isn't any solution to this other than don't go low on blood or hope the devs change how it works. Just feel like voicing this issue and seeing if anyone else feels the same. Now I'm gonna go loot my restroom and hope I find some Advils.
